Markdown won. Your notes are plain files. Your specs are plain files. Agents read and write markdown better than any format ever made. So now every tool wants to live where your files live.
Most of them are good. Most of them answer a different question than Stet does.
brief/launch-plan.md
The brief is a plain file any agent can edit.
Review the agent's edits after it finishes. Every agent edit is reviewed before it lands.
An agent edit, caught in review.
Where do I think? That's Obsidian. A vault for connecting ideas, with a plugin for everything. Keep it. Stet and Obsidian →
Where do my agents keep their memory? That's OpenKnowledge. A wiki agents can grow on their own. A different bet than ours. Stet and OpenKnowledge →
Where do I run my coding agents? That's Nimbalyst, or Cursor. Cockpits for shipping software. Stet and Nimbalyst →
What did the AI paste into my draft? That's iA Writer. It dims the text you didn't write. We admire it. Stet and iA Writer →
Who approved this?
That one is Stet.
Stet is a document editor for writing that carries your name. The spec that ships. The brief the agent acts on. The SOW that gets signed. Agents propose changes. You review each one and accept, reject, or refine it. Nothing lands without your sign-off, and the record of what you approved stays with the file.
The other tools trust the AI and check later, or never. Stet asks first. That's the whole product, and no one else builds it.
That's Obsidian. A vault for connecting ideas, with a plugin for everything. Keep it.
/compare/openknowledgeThat's OpenKnowledge. A wiki agents can grow on their own. A different bet than ours.
/compare/nimbalystThat's Nimbalyst, or Cursor. Cockpits for shipping software.
/compare/ia-writerThat's iA Writer. It dims the text you didn't write. We admire it.
/compare/google-docs-word-notionThe suites added AI to editors built for a world where only people typed. It shows.
You don't have to leave anything. Stet works on plain markdown in a folder. Keep your vault. Keep your terminal. Keep Claude Code, Codex, whatever comes next. Point Stet at the folder where the words matter, and every change becomes a proposal you can stand behind.
Still using Google Docs or Word for the documents with stakes? That comparison is less friendly. →
