Memory.Wiki FAQ

How is Memory.Wiki different from Notion / Obsidian?

Notion and Obsidian are great as personal knowledge bases for humans. Memory.Wiki is built so the AI can read it. The output is a public URL whose markdown is what every LLM already knows how to consume. No plugin, no SDK, no shared workspace.

You can absolutely use Notion and Memory.Wiki. Many people do: Notion for active editing, Memory.Wiki for the "publish so any AI can read it" moment.

Do I need an account?

No. You can capture and share without signing up. Anonymous captures get a cookie that groups them, and you can sign in later to claim them all into your hub.

How does Memory.Wiki compare to mem0 / OpenMemory / Letta?

Those are backend memory layers for AI agents. They expose an API or MCP server, store atomic memories, and inject context automatically into one tool. Memory.Wiki is a publishing layer: human-shaped content at a public URL that any AI can read across tools. They solve different problems, and you can use both. See How Memory.Wiki Memory works for the technical comparison and MWBench for the cross-AI verification.

Does Memory.Wiki work without paying anything?

Free during beta. After beta, a Pro tier is planned with no functional removals. Pro adds features (Pro hub layout, custom domain, analytics). Document expiry is never a tier feature; every URL is permanent regardless of plan.

Can I edit my docs after publishing?

Yes. If you're signed in, every doc you own is editable from the main editor at memory.wiki/. If you captured anonymously, you got an editToken (stored locally) that lets you edit without signing in. Sign in later and your docs migrate into your account.

Can other people edit my docs?

Per-doc share modes:

• Owner only (default).
• Anyone with link (read).
• Specific people (read or edit, by email allow-list).
• Public (anyone can edit, for collaborative wikis).

What happens to my docs if Memory.Wiki goes away?

The engine is open source on GitHub. The Bundle Spec is a stable contract. Worst case, you export everything as raw markdown and stand it up elsewhere. The URL is the contract, and markdown is portable.

Is the AI memory thing actually useful?

Honest answer: only if you use multiple AI tools daily. If you're a one-vendor user (only ChatGPT, only Claude), that vendor's built-in memory is probably enough. Memory.Wiki starts paying off once you regularly switch between Claude / ChatGPT / Cursor / Codex and want the answer from one tool to inform the next.

Where does the name come from?

Memory + Wiki. Your memory, as a wiki, at a URL. Pronounced however you like.
