Edit Like a
Pro

Fable (fable.la) is an AI text editor and collaborative document editor for your desktop. You say what should change, like ‘tighten the second paragraph,’ by typing or speaking, and the AI applies that edit to your existing document while you watch. Every edit is shown as a diff, saved to the history and can be undone. It’s built for anyone who revises long documents: writers, lawyers, academics, technical writers and teams working on a document together.

No. Fable (fable.la) is an independent desktop app for editing documents with AI. Anthropic’s Claude Fable is an AI model and OpenAI’s Fable is a text-to-speech voice; neither is related to this app. Fable uses AI models from several providers to apply your edits, but Fable itself is an editor, not a model.

Dictation apps turn your speech into typed text. Fable takes a spoken instruction about text you already have, like ‘make this section more formal’ or ‘cut this down to 200 words,’ and applies the edit to your document. You can dictate new text too, but the point is revising long documents, by voice or by typing.

Type it, or press the record button and say it. Use plain language, like ‘make the opening more direct’ or ‘add a section covering the budget breakdown.’ Your instruction is sent to our servers, which forward it to the AI to make targeted edits to your document in real time.

When you give an instruction, its text and your current document are sent to our servers, which forward them to the AI for editing. If you speak the instruction, the audio is transcribed on your computer and does not leave it. The AI providers we use work under zero-data-retention terms and agree not to keep your text. Your documents themselves are stored on our servers, encrypted at rest, so they sync and can be shared.

Yes. Fable supports real-time collaboration — everyone sees changes as they happen. You can invite collaborators as owners, editors, or viewers. Viewers can leave suggestions that editors can accept or reject.

When you give an instruction, Fable’s AI reads your full document, understands your intent, and streams targeted edits in real time. It preserves your tone and style, explains every change, and you see exactly what was modified with diff highlights.

No. Every instruction can be typed. Voice is there for when speaking is faster.

Yes. The built-in assistant reads across the documents in your project, answers questions about them, and can propose edits or new documents that you approve with one click.

Yes. Import Word, PDF, Markdown and plain-text files, and export your work to Markdown, plain text, Word, HTML or PDF.

Fable is a native desktop application available for macOS and Windows. It’s fast and lightweight, with an internet connection required for AI editing and document sync.

Fable is free to start: every new account gets $5 in free editing credits, enough to try it on your own documents. After that you can subscribe to Pro for $20/month, which refills your credits every month, or buy one-time top-up packs when you need more.

Fable runs on credits. Sign up free and you get $5 in editing credits to try it out. The Pro plan is $20/month and refills your credits every billing cycle, plus you get unlimited projects and real-time collaboration. If you ever need more, you can buy one-time top-up packs that never expire. The project owner pays for AI usage in their projects — collaborators don’t need their own plan. Every edit shows its cost in the history timeline so there are no surprises.
