Per-file access
Shared, read-only, or private: per file or per folder, per person or per agent. Private means private. Not even an admin can open your private tree, and no setting exists that would let them.
Memava looks like a notes app and behaves like an operating system for what your team knows: people, deals, projects, decisions, and everything your AI agents learn along the way.
A note in Memava: a teammate present and typing, the agent's filing in the body, and every note that links back, one panel down.
Open any note and just type. A teammate in the same note shows up with a named cursor and your keystrokes weave together instead of colliding. No locks, no "someone else is editing", no reading a doc over a screen share like it is 2019.
Your AI finishes a call summary, updates the deal note, files a new fact about a client. You watch the words arrive in the open note, signed with the agent's name. It is a little eerie the first time. Then it is just Tuesday.
Notes link with double brackets, every note knows what points back at it, and search covers everything you are allowed to see and nothing you are not.
The graph draws your vault as a map: one note in focus with everything it touches, or the whole vault as a drifting constellation. Teammates appear beside whatever they are reading, and notes you have never opened stay fogged until you go exploring. Yes, your knowledge base has fog of war.
Ask any note who changed it, when, and what it said before. One click rewinds it, and the rewind itself joins the record. Nothing here can be quietly rewritten, which does wonders for how much people trust what they read.
Shared, read-only, or private: per file or per folder, per person or per agent. Private means private. Not even an admin can open your private tree, and no setting exists that would let them.
An AI touches only what you explicitly granted it, and "share with everyone" never quietly includes the AI. Switch an agent to Proposals only and none of its changes to notes land until a person accepts them, and one button undoes everything an agent did in a sitting.
Every save carries its author, human or agent. There is no anonymous edit in Memava, which is a surprisingly effective behavioral policy for humans and robots alike.
Turn on Alerts and this device gets one summary notification an hour, at most, when teammates or agents change things: authors and counts only, never note contents. Quiet is still the default.
Any note becomes a read-only public link in one tap: revocable, counted, and honest about being public before you mint it. Everything else stays exactly as private as it was.
Notes you have opened stay readable offline, each copy labeled with its age. Signing out wipes the offline copies on that browser.
Sign in once by email, add a passkey, and from then on the vault opens with a look or a touch. Several devices, one identity, revocable per device.
Your vault is a folder of markdown. The Import button brings an existing one in (an Obsidian vault included), images and PDFs travelling with their links intact, and the Export button hands everything back as a zip whenever you like. Leaving is easy. That is precisely why staying feels safe.
Access rules read like sentences because they are sentences: who, what, how much. The same grammar binds people and AI, a private tree stays private from everyone including admins and agents, and an agent never inherits access from a rule about "everyone".
This panel is real: it is how permissions actually look inside the product.
The live shared vault, per-file access with private trees, attributed history with revert, search and backlinks, the graph view with live presence and fog of war, and the MCP connection for any AI agent.
Boards of cards and arrows in the open JSON Canvas format (an Obsidian canvas opens unchanged). A fenced query in any note draws a live table of the notes that match. Callouts, highlights, footnotes, tags and note embeds render the way you typed them.
Semantic search and saved graph perspectives. We tell you which is which before you sign anything.
