A quiet place to write, and an assistant that respects it
Papeliz is a Markdown editor and AI-powered note-taking app for building your personal knowledge base. It works on a folder of notes you already own, with a built-in AI assistant.
What we believe
Your files
Notes are plain Markdown in a folder you own. No special format and no lock-in: a folder from another Markdown app opens in Papeliz as it is, and keeps working in that app.
Your key, your provider
The assistant talks straight from your device to the provider you choose. There is no Papeliz server in between, so Papeliz never sees your key or your notes.
The AI proposes, you decide
Every change the assistant wants to make arrives as a diff you accept or reject. It never writes silently.
An editor first
The assistant rewrites a selection, proposes changes, and suggests links and tags across notes. Papeliz is an editor with an assistant, not a chatbot that answers questions about your documents.
Use it anywhere
Papeliz runs on the web, Windows, macOS, Linux, Android, iOS and HarmonyOS. Open a folder of notes and start writing.
Open source
The whole app is released under the MIT License, so anyone can read it, change it and share it.
