Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 70 of the 101 other AI agents we grade
Mem0 is a memory service for AI agents and apps. Developers add conversation messages through an SDK or API, and Mem0 stores condensed memories per user that the agent can search in later sessions. It is offered as a hosted platform and as an open-source version that runs on your own servers.
To get you started, here are 8 things to know about Mem0, taken from its own pages and our grades.
No store rating, and you add it to your own agent through SDKs or an MCP server.
- 1
Best for adding long-term memory to an AI agent through code
Mem0 is a memory layer that lets agents remember users across sessions, with SDKs in Python and JavaScript and an open-source version.
- 2
There is a free plan
Unlimited end users; 10,000 adds and 1,000 retrievals a month for the first 30 days, or 50,000 adds and 10,000 retrievals a month with your own LLM key.
- 3
It runs on Web
Web.
- 4
Persistent memory
Messages are added per user and searched later, so an agent can recall preferences and facts across sessions.
- 5
Memory compression
The vendor says chat history is condensed into compact memories to cut tokens and latency.
- 6
Python and JavaScript SDKs
A few lines of code add and search memories, and the docs include setup guides for 22 frameworks and tools such as LangChain, CrewAI and the Vercel AI SDK.
- 7
A 2.6 GPA, above 70 of 101
That is against the other AI agents we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace Mem0 you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for adding long-term memory to an AI agent through code
Mem0 is a memory layer that lets agents remember users across sessions, with SDKs in Python and JavaScript and an open-source version. The Free plan's hosted limits shrink after 30 days unless you add your own LLM key, and the paid plan has no published price.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | An open-source version you can run yourself, and a Free plan with unlimited end users. The only other plan is Custom, with no price shown. |
| Free plan and trial | B | Free gives 10,000 adds and 1,000 retrievals a month for 30 days, then 50,000 adds and 10,000 retrievals with your own LLM key. |
| Features | C | It does the memory job fully but only that job. Graph memory, user profiles, analytics and SSO are Custom only. |
| Ease of use | D | No store rating, and you add it to your own agent through SDKs or an MCP server. |
| Platforms and integrations | B | Web, with Python and JavaScript SDKs and LangChain, CrewAI, LlamaIndex, Claude Code and Cursor listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Mem0 is for
- Fits if you are a developer who wants your agent to remember users
- Works for teams already on LangChain, CrewAI or the Vercel AI SDK
Who it is not for
- Skip it if you want a finished agent, as it is only the memory part
- Tight if you stay free, since after 30 days hosted model calls need your own LLM key
- Not for you if you need graph memory or SSO, because those are Custom only
- Watch out: usage past the free limits is billed, but the page states no rates
Good to know
Good for
- Developers adding long-term memory to chatbots, support agents and voice agents
- Teams that want to self-host memory for data-control reasons
- Builders who can bring their own LLM key to get higher free limits
Worth knowing
- The pricing page shows only a Free plan and a Custom plan; the price of Custom is not published.
- The Free plan includes 10,000 adds and 1,000 retrievals for the first 30 days with model calls on Mem0; after that you supply your own LLM key.
- Graph memory, user profiles, advanced analytics, SSO, audit logs and on-prem deployment are limited to Custom.
- Past the free limits, usage is billed, but the page does not state the rates.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
70/101
Other AI agents it is graded above
Mem0's GPA of 2.6 is higher than 70 of the 101 other AI agents we grade, and level with 17.
It stands best on value for money (A, above 91 of 101) and worst on ease of use (D, above 0).
Each grade against the category
Every bar is all 102 AI agents we grade, cut by the letter each got. Mem0’s own letter is outlined.
- AValue for moneyAbove 91 of 101
- BFree plan and trialAbove 82 of 101
- CFeaturesAbove 1 of 101
- DEase of useAbove 0 of 101
- BPlatforms and integrationsAbove 20 of 101
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Mem0 you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 2.6 is higher than 70 of the 101 other AI agents we grade. Mem0 is open source, so there is a third way: take its code and run it yourself.
What you could not
- An AI agent, with the models and the safeguards behind it.
- It plugs into other products, LangChain, CrewAI and LlamaIndex among them, and has an API.
What this rests on. Mem0’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
