Same Google account on any device = same files

Welcome to MarkVault

A Markdown workspace that reads your notes as a whole, not one file at a time. It works offline, syncs across devices, and the heavy thinking runs in this browser — your notes don't leave it.

📂

Bring anything in

Drop a .md file, a whole vault .zip (Obsidian, Notion, Bear — folders preserved), or a .pdf / .docx / .xlsx to convert. Everything autosaves and works offline.

◎

It maps itself

The Atlas (⌘⇧L) clusters your vault by meaning, names each topic in your own words, and flags duplicates, orphans and the notes bridging two subjects. The graph (⌘⇧G) draws the [[links]] you wrote. Both run on-device, for free.

✦

Search by meaning · remember what you read

Toggle ✦ in search to find the note you meant, not the word you typed. Any note becomes a spaced-repetition deck (SM-2). Every save is snapshotted, so nothing is ever really lost — and the mic in the editor dictates straight to your cursor.

☁

Sync, share, done

Sign in with Google and the same files appear on every device. Share any note as a real page — your reading width, view analytics, and inline comments from anyone you send it to.

⌂

Where would you like to start?

You can always come back to this from ?. Home (⌘⇧H) is where your recents, due reviews, topics and loose ends live.

Share "file"

Share links require Firebase sync to be connected — the link is stored in Firestore so anyone can access it.
