Recarga o inicia sesión desde el mismo mensaje. • Las imágenes que añades en el móvil a personajes y mundos llegan ahora a tus otros dispositivos. • Cambiar entre versiones de un turno mantiene tu posición. • Correcciones en todas partes.

Muse Wonder and Gemini 4 Argon join, GPT and Inkling leave

Muse Wonder joins the model picker and tops the shortlist as best overall. It writes consensual sex and graphic violence and says no, in its own words, to coerced sex. Gemini 4 Argon joins as a family of its own rather than the next Gemini Pro: it refuses explicit sex where Pro writes it, and still writes violence. GPT 6.1 Sol and Inkling leave the picker on usage; turns already written on them keep their names in the log. The shortlist is Muse, Gemini Pro and DeepSeek.

A smaller ceiling on invites

An invite still earns you 30% of every top-up the person you invited makes, and the lifetime ceiling per invited reader is now 1,000 credits. Anyone you invited before today stays on the 5,000 they joined under. The 200 credits an invited reader starts with on top of the welcome grant are unchanged.

Versión 0.16.6

• La lectura en voz alta suena donde antes se quedaba en silencio. • La lectura en voz alta tiene una sola barra en todos los dispositivos: tiempo transcurrido sobre el total, con pausar y detener juntos. • Escuchar abre su hoja, y desde ahí una lectura vuelve a empezar. • Dos voces nuevas para escuchar. • Correcciones en todas partes.

Versión 0.16.5

• Una ilustración o un clip aparece donde lo pediste, no entre tu línea y su respuesta. • Un turno sigue escribiéndose si sales de la app, y el que corta una conexión perdida se retoma en vez de pagarse dos veces. • Los selectores de imagen y vídeo dan el precio de cada modelo. • Las ediciones y los borrados se mantienen en todos los dispositivos. • Correcciones en todas partes.

Flux 3 draws, Seedance 2.5 animates

Flux 3 joins the models you can illustrate on, at twelve credits a picture. It keeps close to what you ask for, down to the medium: an oil painting comes back as an oil painting, an ink drawing as ink. It sits behind a filter that lets a battlefield through and turns a nude away. Seedance 2.5 joins the models you can animate on: four to fifteen seconds, up to 1080p, sound on every clip. It moves a painted or drawn picture and refuses a photographic one with a person in it, so it is the model for illustrated scenes; a clip it refuses costs nothing. Five seconds at 720p come to two hundred and eighty-eight credits, against fifty-eight on MiniMax H3 Max, which stays the default.

GPT moves to 6.1

GPT 6.1 Sol takes the GPT slot in the model picker at a quarter of Astra's price: three credits per thousand characters, against fifteen. The 1M context is unchanged. If GPT was your model, it still is; turns already written on GPT 6 Astra keep its name in the log.

Versión 0.16.4

• El botón de enviar conserva su sitio en las pantallas estrechas. Lo que se acorta es el nombre del modelo, si es largo.

DeepSeek's version is a number

The version beside a model's name is a number and nothing else, so DeepSeek's reads 4.1. V4 Pro leaves the versions you can keep DeepSeek on: it was a different model rather than an earlier release of the same one. If you had kept DeepSeek on V4 Pro, your next turn is written on 4.1 and the scene says so once. Turns already written on V4 Pro keep its name in the log.

Versión 0.16.3

• Una cuenta nueva empieza con 200 créditos. La persona a la que invitas empieza con 400. • Una historia avanza cuatro turnos antes de pedirte una cuenta.

Versión 0.16.2

• Las escenas largas leen sus turnos antiguos a través de notas que guarda cada turno, y ya no se detienen a condensar. • Mientras el motor piensa antes de su primera línea, el turno muestra cuánto tiempo lleva. • Un inicio abre la preparación de la escena con una premisa breve que puedes cambiar antes de la apertura. • Fija un modelo en la versión que elegiste, o deja que siga la más reciente. • Correcciones en todas partes.

New pictures, new clips

Qwen Image 3 Pro is the new default for illustrations: it draws the dark scenes up close where Seedream kept its distance, and costs a little less. Muse joins at four credits a picture and GPT Image 2.5 for the finest detail, both behind a strict filter. To animate, MiniMax H3 Max is the new default: sound on every clip, and now up to 1080p. Wan 3.0 takes over from Wan 2.7 for less, and Gemini Omni Flash takes Veo's place for cinematic shots at a quarter of the price. Seedream, Kling, Veo, Krea, Nano Banana 2 Lite and MiniMax Turbo leave the pickers. If Wan was your model, it still is; pictures and clips already made keep the name they were made on.

Versión 0.16.1

• Empieza una historia solo con un mundo. Sin protagonista diriges la escena desde fuera: cada línea que envías es una indicación. • La longitud de la respuesta ahora la decide el narrador, y que el motor no toque a tu personaje se activa en Narración. • La estantería de la comunidad lo muestra todo; un ajuste vuelve a cerrarla. • Correcciones en todas partes.

Opus moves to 5.5

Opus 5.5 takes the Opus slot in the model picker, and it costs a fifth less than Opus 5: six credits per thousand characters in the picker, against eight. The 1M context is unchanged. If Opus was your model, it still is; turns already written on Opus 5 keep its name in the log.

Grok moves to 4.7

Grok 4.7 takes the Grok slot in the model picker, and it now thinks before it writes. The old setting hurried it to the first line; reading whole scenes side by side, the deliberating version holds the room better, lets feeling arrive through a gesture instead of naming it, and stops tidying its own tension away. That costs time and credits: first prose lands in under a minute on a long chapter rather than half of one, and a thousand characters costs five credits where 4.6 cost two. Grok still holds a scene's language where 4.6 would answer German prose in English, still balks at least, and is still the one-tap retry when another model refuses a passage. The 500k context is unchanged. Grok now runs straight from xAI instead of through an intermediary, which is quicker and drops a system prompt that rode every turn; xAI sees the prose and never the reader, and the model picker's privacy badge says so. Turns already written on 4.6 keep its name in the log.

Versión 0.16.0

• ¿Primera vez? Tu primera escena son tres campos: tu nombre, a quién conoces, dónde empieza. El motor escribe a partir de ahí. • Una escena con un solo personaje ahora abre con una línea de contexto. Elige quién habla primero: su saludo, tu propia línea, o deja ambos vacíos y el motor abre la escena. • Un personaje escrito a partir de una línea habla de él, nunca de ti. • Correcciones en todas partes.

DeepSeek moves to V4.1

DeepSeek V4.1 Flash takes the DeepSeek slot in the model picker. On the same scenes it wrote cleaner prose than V4 Pro — fewer stock phrases, half the dashes — and it costs half as much: one credit per thousand characters in the picker, against two on V4 Pro. It thinks before it writes and keeps the 1M context. If DeepSeek was your model, it still is; turns already written on V4 Pro keep its name in the log.

Versión 0.15.9

• Una historia ya no lleva dentro una copia de los retratos de su reparto, así que cada turno envía mucho menos, sobre todo en el móvil. Las historias que ya tienes adelgazan la próxima vez que se guardan. • Las historias borradas se eliminan según lo previsto a los treinta días.

Versión 0.15.8

• Publica un mundo o un personaje en la estantería de la comunidad desde el móvil. Tu firma y tus enlaces privados están en Ajustes, y una tarjeta tuya se puede retirar. • Una tarjeta de la comunidad se abre en la ficha que ya conoces; las tarjetas muestran la imagen y el nombre. • Un capítulo largo cuesta menos por turno: la app resume antes y envía solo lo que necesita el siguiente turno. • Importar pasa a Ajustes; el botón más solo crea. • Correcciones en todas partes.

Versión 0.15.7

• Empieza una escena desde una tarjeta de la comunidad: el mundo da el marco, el personaje se une a tu reparto. • La estantería ordena por nuevo o popular y filtra por etiqueta; las tarjetas muestran resumen, etiquetas y tamaño, y el reparto de un mundo en retratos. • ¿Bloqueaste a alguien sin querer? Ajustes lista a los autores bloqueados, con el camino de vuelta. • Una escena de 150 turnos o más vuelve a generarse en lugar de fallar en silencio. • Correcciones en todas partes.

Versión 0.15.6

• Un turno sigue escribiéndose si se cae la conexión o sales de la app, y al volver retoma donde lo dejó. • Detener un turno surte efecto aunque la red se trague el primer intento. • El registro muestra lo que cuestan las imágenes, los clips y la narración, no solo los turnos. • Las historias dejan de cambiarse el título a mitad de capítulo, y una historia abre en su turno más reciente. • Correcciones en todas partes.

Versión 0.15.5

• Corrección de errores y mejoras de estabilidad.

Gemini Flash moves up a version

Gemini 3.8 Flash takes the Flash slot and stays the default story model — the same 1M context and the same rate per token as 3.7. It does think longer before it writes: measured on the same scenes, deep in a long chapter it spends about twice the hidden reasoning 3.7 spent for the same paragraphs, so the picker prices Flash at three credits per thousand characters instead of two. Turns already written on 3.7 keep its name in the log.

Half of the cheapest clip

MiniMax H3 Max Turbo joins the models you can animate on: the same five to fifteen seconds, the same 480p and 768p, sound on every clip, at half of H3 Max's price. Five seconds at 768p costs twelve credits, against twenty-four on H3 Max and a hundred and sixty-four on Grok. H3 Max keeps its place in the picker.

Versión 0.15.4

• GLM 5.2 y Grok 4.6 se suman a los modelos recomendados: el turno más barato y los menos rechazos. • MiniMax H3 Max anima clips con sonido por un tercio de los créditos.

A cheaper clip

MiniMax H3 Max joins the models you can animate on: five to fifteen seconds, 480p or 768p, sound on every clip, and well under half the price of anything else here that carries sound. HappyHorse leaves the picker in the same breath — MiniMax does its job for a third of the credits. Clips already animated on it keep its name.

Versión 0.15.3

• Publica historias, personajes y mundos en el estante de la comunidad — y hojea lo que otros dejaron allí. • Las comillas hacen de una línea diálogo, la barra dirige la escena, la prosa desnuda sigue siendo prosa. • En Roleplay su cabeza está abierta; la tuya sigue siendo tuya. • La apertura que escribiste sobrevive al cambio Story-Roleplay. • Los estantes ordenan lo más nuevo primero. • En Android, los retratos salen del archivo de la biblioteca: carga ligera, escritura que no se atasca.

Versión 0.15.2

• El campo donde escribes flota sobre la prosa, con sitio para un párrafo. • Un prompt de imagen llega en cerca de un segundo, escrito palabra a palabra. • Elige la imagen a animar de un estante: escena, personajes, mundo, tus fotos. • Escribe una línea sobre la descripción y genera el resto. • Una sola clase de consigna por historia: escríbela, nómbrala, úsala donde quieras. • Grok 4.6 y Gemini 3.7 Flash toman sus puestos; las ilustraciones, Grok Imagine 2.

Gemini Flash moves up a version

Gemini 3.7 Flash takes the Flash slot and stays the default story model — the same 1M context and the same rate per turn as 3.6, on a model Google built to hold a longer thread. Turns already written on 3.6 keep its name in the log.

Grok moves up a version

Grok 4.6 takes the Grok slot in the model picker, still set to write rather than deliberate. Illustrations get Grok Imagine 2, and Grok clips animate on Grok Imagine 1.5, which adds 1080p. Turns and images already made on the older versions keep their names in the log.

Versión 0.15.1

• Historia o Rol: elige la forma al configurar. El rol abre con un personaje y espera. • Los controles de narración nombran su sujeto; el narrador en primera persona guarda su interioridad. • Escribe una consigna una vez y úsala en cualquier historia.

Grok is back in the picker

Grok 4.5 rejoins the model lineup, set to write rather than deliberate — it reaches the first line of prose in seconds. Kimi K3 leaves the picker; turns already written on it keep their name in the log.

Versión 0.15.0

• Cinco clásicos llegan a la biblioteca: Orgullo y prejuicio, Jane Eyre, Drácula, Persuasión y Sherlock Holmes. • La biblioteca abre con un escaparate de mundos y comienzos, rehecha para el teléfono. • Elige la narración o escribe una indicación permanente que el narrador sigue. • Adjunta una imagen y el narrador escribe desde lo que ve. • Cualquier pasaje se puede escuchar, con la voz que elijas. • Exporta una historia o toda tu biblioteca como archivo .underfiction portátil.

The Library, rebuilt for the phone

The Library has its own shape on a phone now: a showcase that fits the width, a menu that sizes to its labels, and detail views with one clear way back. The navigation menu stays put on the pages it opens.

Credits read in your language

Credit amounts in logs, generation details, and top-ups are written in the language you are reading, on web, iOS, and Android.

Import says what went wrong

A character card or archive that will not open now names the file and the reason, instead of failing with one generic line.

Model rates on Android

The Android model picker shows what each model costs per turn, matching web and iOS.

Browse the openings on iPhone and Android

The starter browser is native now: page through the built-in worlds, their leads, and every authored opening without leaving the Library.

Directions, grouped at setup

Narration nudges are called directions, and story setup groups them into sections instead of one long list.

Duplicating a character keeps your place

Copying a character asks first and leaves the editor open, instead of dropping you back to the list.

Narration directions

Choose the voice before you write: First Person, Second Person, Present Tense, Inner Thoughts. The narrator holds what you pick for the rest of the scene, and scene summaries now keep that voice instead of pulling the prose back toward third person.

Standing directions

Give a story a direction in your own words — "keep her unreliable", "no dialogue tags" — and every turn follows it. It outlasts compression, travels inside portable archives, and comes along when someone takes the pen on a shared excerpt.

Four new openings in the original worlds

Pip, Syra, Lydia, and Lola each get an authored opening built on a shared secret or a craft rather than a stated romance. They lead their worlds in the library rail, and The Antler & Stone reaches the showcase for the first time.

Private or anonymized, stated plainly

Story and narration model pickers mark which models run inside Venice and which reach the model through anonymized routing. Hover a badge and it spells out what that guarantee covers.

Your library lives on your device

Stories, characters, and worlds are held locally, and nothing about them leaves the device unless you move it yourself. Portable .underfiction archives are how a story or a whole library travels between web, iOS, and Android.

One composer at every width

The prose composer uses a single compact layout from phone to desktop, and long speaker names no longer crowd out the field.

Steadier on every platform

Fixed iOS navigation dismissal and zoom transitions, web header and scrollbar shifts, Android segmented-control sizing, and a setup layout that moved while an animation ran.

The world showcase

The starter grids are now a moving showcase on the landing page and in every Library. Lead characters frame each world, the openings read like a table of contents, and the stage advances on its own until you touch it.

Straight into setup

Pick a world or a character and you land in story setup. The onboarding walkthrough and the separate persona step are gone.

Carry your whole library

Export everything — stories, characters, worlds, images, videos — as one portable .underfiction file, and import it on any other device. Merging keeps whichever copy of a story you edited last.

An empty shelf opens the Library

If you have not written anything yet, your shelf opens on the built-in worlds and characters instead of a blank screen.

The classics in eight languages

The complete classics collection — worlds, canon leads, and openings — is now localized in all eight supported languages.

A new landing page

Rebuilt around the showcase, with starting in the browser as the first move and the native apps a quieter link below it.

Five literary classics

Pride and Prejudice, Jane Eyre, Dracula, Persuasion, and Sherlock Holmes joined the built-in library on web, iOS, and Android — eight canon leads, new cover art, fifteen authored openings. You are not the protagonist by default: you take the governess's chair in Jane Eyre, Anne's position in Persuasion, and elsewhere you arrive beside canon as a confidante or a client.

Recommended models first

The story model picker opens on a clear first group of recommended models, with ratings and prices lined up down the list. Kimi K3 is back in the lineup.

Animate an image from earlier in the story

Any illustration already attached to the story can be the source when you animate a scene, not just the most recent one.

Illustrate and Animate, named the same everywhere

Media actions use the same labels and sit in the same place on web, iOS, and Android.

Stories follow your language

The prose language follows what you write, independent of the interface language. Switch mid-story and the narrator switches with you; keep going and it stays in the scene's language. The per-story language setting is gone, and interface language moved into Preferences.

World artwork on story cards

Story cards show the artwork of the world they belong to again.

Turn actions stay out of the way

Rerun, edit, share, and the rest stay quiet until you reach the passage they belong to.

A design pass across platforms

Tuned story setup, character editing, settings, navigation, and the input bar so web and iOS read as the same product at the same rhythm.

Write from an image

Attach an image to your next turn and the narrator writes from what it sees — a face, a room, a photograph you want in the scene. On web, iOS, and Android.

Read it aloud

Have any passage narrated in the model and voice you choose. Narration is cached on your device, so replaying a passage is free.

Export a story

Take a story whole, or stopped at any earlier turn, as readable Markdown or as a portable .underfiction archive carrying its characters, world, images, and videos.

Library actions in the toolbar

Import, export, and the rest of the library actions moved out of the page body and into the toolbar.

Clearer credit use

Credit spend rounds the way you would read it, and model pricing labels in story setup say what they mean.

Localized menus keep their labels

Fixed menu labels that fell back to English and a language switch that did not always take.

Opus 5

Upgraded Claude Opus from 4.8 to Opus 5 — a step up in long-scene coherence and prose control at the same price. Context window and credits-per-turn are unchanged; existing stories pick it up automatically.

Starter stories and Gemini 3.6 Flash

New starter stories on the landing page and in Library — curated openings you can step into with one tap, now on web, iOS, and Android. The library gained a Mine/Library switch so built-in material and your own work stay cleanly separated. Gemini 3.6 Flash joined the model picker and became the default story model.

Shared story excerpts

Share a moment from any story as an unlisted link — a directive and the prose it produced, in a clean reader view. Readers can take the pen: one tap copies the full setup into their own library so they can continue the scene their way. Links are unlisted and never indexed; only you can share them.

Versión 0.5.0

The platform has a new name and identity. What started as Fablis, then became Unreliable, is now Underfiction — a name that better captures what we're building.
