Writing Studio — The Long-Form Writing IDE with Full-Book Memory

One studio

Two writing studios became one.

Slima used to split writing, screenwriting and reader feedback across separate rooms. Screenwriting now lives inside the Writing Studio as a file type, which means a series bible, its episodes and its world map finally sit in the same tree.

📚

Novels, memoirs, non-fiction

Folders, chapters, reference material. The shape of the project is something you can see, and every part of it is one keystroke away.

🎬

Screenplays and series

A screenplay is a file now, not a separate app. One episode per file, scene cards, cast detection, and export in local or Hollywood format.

🔬

Theses and research

Sources, notes and drafts under one roof, with a version history that shows a supervisor exactly what changed between two readings.

Six file types

A book is more than a pile of chapters.

Most writing apps give you text files and hope you keep the rest in your head. Slima gives the rest of it somewhere to live — and the AI can read all six.

.md

Manuscript

The chapter you are actually writing. Tabs, split view, outline, whole-book search, and a focus mode that dims everything but the paragraph under the cursor.

Quick Open ⌘P
Split view
Zen mode

.script

Screenplay

One episode per file, with its own scenes and elements rather than a text file pretending to be a screenplay. Cast is detected from the dialogue; runtime is estimated as you write.

PDF · Word · Fountain

.map

Relationship board

Who knows whom, and who is lying about it. Marquee-select a faction and move it together, snap to guides, undo with ⌘Z, drop a note onto the canvas and it becomes a card.

.geomap Beta

World map

Draw the world the story happens in. Water, land and mountain brushes plus forest, thirty-seven place symbols, rivers that clip themselves where they meet the sea, and labels that thin out as you zoom. The map is still in beta and more brushes are coming.

.timeline

Story timeline

The story's events on one axis, and a chapter or note dragged in becomes one of them. Swimlanes show how a character's line crosses a plotline, and you can give your world its own calendar — month names, days per month, the name of the era.

Solo a character

.beats

Beat board

Acts are columns, beats are cards, and a card can hold the chapter file it turns into. Drag a chapter in from the tree; drag beats between acts when the shape of the book changes.

Four structure templates
Cards hold files
Screenplay cards expand

Images, PDFs and data files open in the tree too. Every type carries its own comments, so a note about a scene stays attached to that scene.

AI that edits structure

It stopped just writing sentences and started editing the file.

Ask for a new scene, a moved city, an extra beat in act two, and the change arrives where it belongs. The AI addresses one field at a time, so nothing you did not mention gets quietly overwritten.

Screenplays, beat boards, relationship boards, world maps and timelines are all editable
Changes appear on the page as ghost cards — accept or skip them one at a time (the world map lists its changes in a review bar instead)
A batch is all-or-nothing: if step four fails, steps one to three are not applied

Full-book memory

It remembers every word you wrote before.

Ask about a character from the opening while you are writing the ending. Slima keeps people, places and setups straight, and flags the contradiction before a reader finds it.

Catches details that drifted between chapters
No more pasting a recap in before every question

Continuity check

Cross-referenced across all 40 chapters

✓ Elena's eyes, green ch. 2

! Marcus: teacher → lawyer ch. 7

✓ Timeline consistent March–September

✓ Pendant set up before the reveal ch. 9

AI Coach

A reader who knows your whole story.

Ask about pacing, a character, or whether the ending lands. The answer comes out of your book rather than out of generic advice that ignores the chapters you already wrote.

Answers inside the context of your own story
Select any line for a quick rewrite or a note

You · writing ch. 7

Is Eleanor consistent here? She felt sharper in chapter three.

Slima Coach

She is. Chapter three is after the storm, when she is angry. In seven she is frightened, so the short sentences fit. If you want the edge back, it is the moment she decides the boats are not coming back.

Version control

Rewrite hard, lose nothing.

Every save is a version you can return to, and Slima takes a snapshot before the AI touches anything. Two devices editing the same chapter no longer overwrite each other in silence — you get told, and you choose.

Writing journey

The record of how it was written, kept as you write it.

Platforms are starting to ask authors to declare how AI was involved. Slima records the process while it happens — every version, what was pasted or imported, what the AI wrote, and every AI consultation — so you have something concrete to answer with instead of a memory of last spring.

Watch the book grow

Play the whole project back on a time axis, or step through a passage keystroke by keystroke. Anything the AI wrote is marked in purple as it replays.

🔗

A public page and a badge

Share the process with readers on a page of its own, and drop the badge on your author profile or blog. The link points back here, which is what makes it hard to fake.

📋

A declaration you can fill in

Reference figures laid out against what Kakuyomu, Shōsetsuka ni Narō and Amazon KDP each ask for. The numbers are stated; the judgement stays yours.

These are process records and a basis for a declaration. They are not a verdict on how a piece of writing was made, and Slima does not present them as one.

Day to day

Reading, listening, dictating, arguing in the margin.

Writing a long book is not eight hours of typing. Most of the work is the other things.

📖

Read it back out loud

Switch the editor into a reading layout and have it read from any paragraph you click. In a screenplay you can give each character their own voice.

🎙️

Dictate with punctuation

Say “comma” and get one. Install the offline model and it starts inferring punctuation from your pauses — and the audio never leaves the device.

💬

Comments on everything

Screenplays, beat boards, relationship boards, world maps and timelines all take comments now. Click one and it jumps to the exact card it belongs to.

📊

Chapter status, at a glance

Give each chapter a target word count and a state — drafting, in review, done. The manuscript table shows the whole book on one screen.

It stays yours

Written here, readable anywhere.

Nothing in Slima is a trap. The book leaves in formats other people can open, and other tools can reach in without a plugin.

📤

Seven export formats

Markdown, plain text, Word, EPUB, PDF, Fountain, or the whole project as a .slima archive. Screenplays come out in local or Hollywood layout.

📱

Rebuilt for phones

The editor, the file tree, the AI panel and the team area were laid out again for a small screen. Menus rise from the bottom; the tap targets are big enough to hit.

🔌

Open it from your own tools

Slima MCP lets an assistant on your desktop read and write the same book, over an open standard rather than a private integration.

🔒

You decide what is public

Share a draft by link, publish a writing-journey page, issue a certificate — the privacy centre lists everything you have made public and revokes any of it in one click. Your work is never used to train models and is never shown to other users.

“I get distracted easily and writing flow is hard to find. Before Slima, whenever I had two different directions for a plot, I had to manage two versions myself — and just switching between them would break the flow I'd barely settled into. Now I can edit freely and, once a writing session wraps up, pull out whichever version I need.”

Questions

Before you start.

What happened to Script Studio? +

It is winding down, and screenwriting moved into the Writing Studio as a file type. Existing screenplay projects stay open and there is a converter in each project's ⋯ menu that copies it across as a Writing Studio book. New screenplays start in the Writing Studio.

Do I have to use the maps and boards? +

No. A book with nothing but chapters in it works exactly as it did. The extra file types appear in the “new file” menu when you want them and stay out of the way when you do not.

Can the AI overwrite my chapter? +

Not without you seeing it. A snapshot is taken before any AI action, prose edits arrive as suggestions, and edits to the structured file types show up on the page for you to accept or skip individually.

Is my writing used to train models? +

No. Your work is never used to train models and is never shown to other users. What we do disclose — including the narrow cases where someone here could see a manuscript — is written out in the privacy policy rather than summarised into a slogan.

Can I work offline? +

Writing and editing work offline; the book lives in your browser's local database and syncs when you reconnect. Anything that calls the AI needs a connection.

What does it cost? +

There is a free tier with no time limit. Paid plans start at US$12 a month and are the same price everywhere in the world, with no per-region conversion.

Open a book and write a paragraph.

That is the whole evaluation. If the studio fits how you work, you will know inside an afternoon.
