MemoryFirst vs Mem0
Mem0 is a memory layer for AI agents consumed via SDK or API: you decide what to remember, when to write it, and how to surface it, because you integrate it inside your own product. It has three plans (as of July 2026): Free, Starter at $19/month and Pro at $249/month. Graph memory, its most advanced feature, is only available on the Pro plan.
MemoryFirst solves an adjacent but different problem: it’s not a piece you integrate into your product, it is the product. You connect over MCP, connect your sources (email, chat, documents, your Claude Code sessions too) and get business memory with a temporal graph and citations from the first paid plan, without writing a line of integration code.
| Mem0 | MemoryFirst | |
|---|---|---|
| What it remembers | Facts and preferences extracted from conversations, meant for YOU to use inside your own product. | Structured business memory (decisions, clients, deadlines, blockers), with provenance, ready to query without building anything on top. |
| Delivery format | SDK / API you integrate into your application. Developer infrastructure. | Finished product: MCP ready to connect, morning brief, no integration code. |
| Temporal graph | Available only on the Pro plan, $249/month. | Included from the entry plan, €19/month. |
| Verifiable citations | Fact memory; no citation to the source fragment shows up in the answer. | Every answer cites the exact fragment and source. |
| Data residency | SOC2 certification. “GDPR compliant” shows up as a footnote, no EU residency stated. | Data hosted in the European Union, with region selection, as a core argument. |
| Entry price | Free / Starter $19 / Pro $249 (as of July 2026). | Free / Founder €19 (graph included). |
| Who it's for | Development teams building their own AI product and needing a programmable memory layer. | Founders and teams who want to use memory that's already built, without writing integration code. |

Mem0 is infrastructure; MemoryFirst is a finished product
If your job is building an AI product and you need memory as one more component of your stack, Mem0 is a solid, established choice. If your job is running a company and you want AI to remember that business without writing code, that programmable layer isn’t what you need: you need something already built.
Choose them if...
you’re building your own AI product and need a programmable memory layer over an SDK, with full control over how it integrates into your stack, and $249/month for the graph isn’t a barrier at your scale.
If you’d rather understand what a temporal graph does for your memory first, start with the glossary. And if you already know you want the graph included without paying $249/month for it, see what MemoryFirst costs.
The temporal graph, without the $249 plan
