What Mem0 is
Mem0 gives developers a memory they can add to the AI products they build, through an API. It has a free Hobby plan with 10,000 memories added and 1,000 searches a month, then Starter at $19 a month and Pro at $249 a month (Mem0's pricing).
It also offers an MCP server, so apps like Claude Desktop, Claude Code, Codex and Cursor can use your Mem0 memory directly. You need a Mem0 account, and the quick setup runs a command that needs Node.js. Mem0's docs are plain about where things live: "Nothing runs on your machine", and the memories "live in your Mem0 account, not on your computer" (Mem0's MCP docs). Its OpenMemory page describes memory for "every MCP-compatible coding agent" (OpenMemory).
Where Zaaheen differs
- Where your memories are kept. Zaaheen keeps them encrypted on your own computer. Our servers handle sign-in and your subscription, and never receive your memories.
- Who it's for. Mem0 is built for developers. Zaaheen is for anyone who uses several AI apps: you install it like any other program and connect each app from its Agents tab.
- Apps. Both reach Claude Desktop, Claude Code, Codex and Cursor. Zaaheen also connects to the ChatGPT app for your computer.

Does a shared memory hold up across apps? We tested ours: five AI apps on one Windows computer, sharing one Zaaheen memory, answering eight questions about the person.

Where Mem0 is the better choice
If you're a developer adding memory to a product of your own, Mem0 is built for exactly that and Zaaheen isn't: it has an API, a free plan, open-source code and options to run it yourself. It also suits you if you'd rather your memory lived online and followed you to any computer.
Where Zaaheen falls short
- It runs on Windows and on Macs with Apple chips only, with no Linux or phone version.
- Your memory lives on one computer; there is no sync between computers yet.
- It has no API for building your own apps, and it isn't open source.
- After the 30-day trial there is no free plan.
