Features · Text

Write documents, with AI that edits alongside you.

Draft, rewrite, autocomplete and illustrate without leaving the document. Frontier cloud models on your own keys, or open-weight models free and offline on your machine. Split long pieces into pages and export them as a multi-page PDF or EPUB.

Choose

Frontier cloud or free local.

Use frontier cloud models like Claude, GPT, and Gemini on your own API keys when you want the best prose, or open-weight models like Gemma, Qwen, and Llama running on your own machine when you want free, offline, and private. It is the same editor either way, and you can switch per document or leave the picker on Auto and let the prompt choose the model.
Draft

Prompt in, draft streamed onto the page.

Your prompt streams straight into the document, appending, replacing a selection, or inserting at the caret depending on what you asked. Follow-ups build on the instructions you already gave, and any rewrite can be undone with one click.
Revise

Fix the sentence, not the document.

Select a clumsy passage and a floating toolbar appears: Shorten, Expand, and Improve up front, plus fix grammar, simplify, summarize, continue writing, change the tone, or translate into a dozen languages under More. The rewrite streams in over exactly that range while everything around it stays put, and a Keep / Discard bar lets you undo it instantly. ⌘J improves the selection without leaving the keyboard.
Enhance

Say it roughly, send it precisely.

Here the prompt is an instruction to the writer, so the wand sharpens the ask: what to change, which part of the document it applies to, and the tone, format, and length you want. With a passage selected it scopes itself to that passage. It never drafts the document itself.Text is the cheap place to be vague, so here the wand buys accuracy rather than money.
Editor

An editor first, AI second.

Underneath the AI is a proper writing tool, with real formats, real formatting, and files that stay yours. The model helps in place instead of replacing your editor.

Rich text, Markdown, or plain text

Create .html, .md, or .txt documents and format with a full ribbon: headings, bold and italics, lists, case transforms. Type / for a block menu, ⌘F to find in the document, and watch live word, character, and token counts in the footer. Everything autosaves as you type, to ordinary files any other editor can open.

Autocomplete that waits for you

Pause for a moment and a greyed continuation appears at the caret: Tab accepts all of it, ⌘→ takes one word at a time, Shift+Right tries another, Esc dismisses. It never touches the file until you accept, uses whichever model you've picked (a local model keeps it offline), and the delay is yours to set: medium (3 s), short (1.2 s), or off.

Split a long piece into pages

Add pages from the Pages panel and drag them into order, or ask for “a 5 part guide” and the model writes every page for you. Export builds the index: a PDF opens with a numbered contents page, and EPUB turns each page into a chapter.

Generate images inside the doc

Select a phrase, hit Generate image, and a placeholder resolves on its own line using your image model. The espresso-tamper shot here is a real Flux 2 Pro generation. You can also drag images, audio, and video straight from your project or the OS into the page: they're copied in beside the document and audio and video become real players you can hit play on, in Markdown as well as rich text.
Workspace

The rest of the writing desk.

The small things you reach for constantly: finding your place in a long draft, grounding a prompt in a source, getting the file back out again.

Export anywhereSend the document out as Markdown, HTML, plain text, a print-styled PDF, or an EPUB e-book: pick a format, choose where it lands, done.
Outline panelToggle a live map of the document's headings and jump straight to any section. Handy once a draft outgrows one screen.
Bring your own contextAttach up to five sources (reference files, or URLs whose readable text is pulled in), then write against them. Sources are clearly fenced off from your instructions.
Instruction historyEvery instruction you've applied to the document stays as a chip above the composer. Click to reuse, and follow-ups like “now make the intro punchier” resolve against what came before.
Find and filter⌘F highlights every match in the document and steps through them; the sidebar filters your files by name as you type.
Files that stay yoursDocuments are ordinary files in your project folder: autosaved, duplicable, revealable in Finder, and openable in any other editor. No database, no lock-in.
Catalog

Available models & providers.

Every text model in the catalog, in one picker. Cloud models run through Runware, OpenRouter and Replicate, or direct from vendors like OpenAI, Anthropic, Google and more, with your own keys; open-weight models run locally through Ollama and the bundled Hugging Face runtime, free and offline.
