# mdfy FAQ

## How is mdfy different from Notion / Obsidian?

Notion and Obsidian are great as personal knowledge bases for *humans*. mdfy 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* mdfy. Many people do — Notion for active editing, mdfy 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 mdfy 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. mdfy 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 mdfy Memory works](/mdfy-memory) for the technical comparison.

## Does mdfy 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 `mdfy.app/`. If you captured anonymously, you got an `editToken` — that's stored locally and 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 mdfy goes away?

The mdcore 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. mdfy 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?

`mdfy` = "modify." It's a verb — you mdfy a thought into a URL. Pronounced however you like.
