The AI writing tool you own.
A real word processor for novels and long work. Your files stay plain Markdown on your disk, the AI runs on your keys or your own machine, and the app is yours for one payment.
Your files
Everything is plain Markdown on your own disk. Open it in any editor, back it up anywhere, leave whenever you like.
Your models
Bring an API key, or run Ollama or LM Studio and keep every word on your machine. No account required for any of it.
Pay once
Wisp Pro is $49, one time. Not a subscription, no seat limits, no activation server. It keeps working offline forever.
The AI
AI stays in the margin. You hold the pen.
Wisp never silently edits your prose. Every suggestion arrives in a review panel showing exactly what would change, and nothing happens without your accept.
Not quite right? Say what was wrong in one line and retry; Wisp remembers what you rejected and will not serve it again. Curious what left your machine? "What was sent" shows the exact prompt, every time.
There is no chat window to manage, and no feature spends a token without a direct gesture from you.
Private by wiring
AI writing that never has to touch a server.
Point Wisp at Ollama or LM Studio and your manuscript never leaves your machine. Or paste a key for OpenRouter or any OpenAI-compatible endpoint and use whatever model you trust.
Any document can be locked to local models only: the promise is stored in the file itself, and Wisp refuses remote calls for it from then on.
- Local models: Ollama and LM Studio, no key, nothing sent
- Your key: OpenRouter, OpenAI, or any compatible endpoint
- Per-document lock: "this file stays on this machine", kept by the app
- Prompt preview: see exactly what was sent, on every suggestion
- No account: nothing to sign into, nothing tracking you
The editor
A real word processor, not a text box.
Everything you expect from a serious writing app, saving to files you already own.
True pages
A paged layout that reflows as you type, a facing-page spread view, and page setup that carries into print and export.
Comments and review
Margin comments stored in the file, resolvable by hand or by the AI, one at a time or in one pass over the whole document.
Chapters and navigation
An outline flyout, a generated contents page, and a jump palette that reaches any chapter, phrase, or page number.
Import and export
Opens Word, PDF text, and Markdown. Exports Markdown, PDF, and Word. Rich paste from Docs and the web just works.
Your work, kept safe
Autosave, snapshots you can reopen read-only, session restore, and files that remain plain text through all of it.
A calm room
Focus mode, typewriter scrolling, ten themes, font pairings built for long reading, and a spellchecker that works offline.
Pricing
