What survives aren't subscriptions —
it is the file.

Suggested: "In an era where AI ships custom enterprise-grade software on demand, what endures isn't the subscription, it's the idea."

AI can generate enterprise-grade software with a fraction of the work it used to take. The assumptions behind SaaS are quietly collapsing. Good software isn't gated by subscriptions anymore, it's gated by good ideas. That's your ideas, whether that means respecting privacy, or integrating with your favorite e-ink tablet. Prose is an answer to the question: What does software look like when it stops being scarce?

What makes it different
*.md
Plain files, always
No databases, no sync servers, no proprietary formats. Your documents are .md files. Open them anywhere. They'll outlast this app.
◉ BYOK
Your keys, your costs
Connect your Anthropic API key directly. No markup, no middleman. Your conversations stay on your machine.
</> MIT
Fully open source
Read every line, fork it, build on it. MIT licensed. Prose exists to be useful — not to manufacture dependency.
✍ rm
reMarkable sync
Write on paper. Prose syncs your reMarkable and runs OCR — handwriting becomes editable markdown in seconds.
⚡ MCP
Agent-accessible
Prose ships an MCP server. Claude Desktop can open, read, and edit your active document without you leaving your flow.
◎ local
Offline-first
No required internet. Write on a plane, in a cabin, when the API is down. Your editor works when you do.
Model Context Protocol
Your editor has an API now.

Prose ships with an MCP server. Point Claude Desktop at it and your editor becomes an agent-accessible workspace — Claude can read your document, suggest edits, and apply them without a single copy-paste.
