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.
버전 0.15.4
• 추천 모델에 GLM 5.2와 Grok 4.6이 합류했습니다. 가장 저렴한 턴, 그리고 가장 적게 거절하는 모델입니다. • MiniMax H3 Max가 소리 있는 클립을 3분의 1의 크레딧으로 움직입니다.
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.

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.
버전 0.15.1

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.

버전 0.12.2

Introduced shared typography, control, surface, and spacing token systems across the app for consistent rhythm and visual language. Refreshed the logo, favicons, and promo video, and polished the navigation icons.

Added a Sentry alert for missing Venice pricing so model gaps get caught before users hit them.

버전 0.5.1
Introducing Worlds — curated world settings with their own characters, lore, and narrative hooks. Four starter worlds ship out of the box: Ashworth End, Linden Park, Antler Lodge, and Marabou Syra. Each world generates dynamic scene suggestions via the LLM so every playthrough starts differently.
버전 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. Added Sentry error tracking with full content redaction, and a pre-flight context window check to catch token overflows before they time out.

Full mobile-responsive pass with touch-optimized interactions and viewport fixes. Added SEO infrastructure: OpenGraph images, JSON-LD, sitemap, and robots.txt. New settings page with model picker, temperature slider, and max response length control.
