Lös – Private Markdown Notes with Local AI

No account, no cloud, no telemetry. Your notes stay on your machine.

Search, ask, and research with models that run entirely on your Mac.

Open format, export anytime. No proprietary lock-in, ever.

Write freely

A Markdown editor that stays out of your way. Your writing is always plain Markdown — no proprietary format, no content loss.

Live Preview — Markdown stays intact while formatting renders inline, like Obsidian.
Three modes — Live Preview, Raw source, and a clean Read view.
Organised — Folders, autosave, and export as Markdown or ZIP.

Your notes become searchable by meaning, not just keywords. Ask a question and get answers grounded in what you've actually written — all on-device.

Semantic search — finds notes by meaning, not just matching words.
Chat with your notes — get answers with clickable source citations back to the original note.
Quick and Deep modes — fast answers or thorough, multi-source responses.

Generate cited research reports without leaving the app. The AI stays on your machine — only your search queries go to the web.

Multi-pass research — plans, searches, reads, and synthesises across multiple sources.
Cited reports — Markdown reports with inline citations, saved directly to your notes.
Three depth presets — Quick (~5 min), Standard (~15 min), or Deep (~30 min).

Privacy isn't a feature we bolted on. It's how the app works.
