Engram vs Mem0
Mem0 summarizes.
Engram remembers every word.
Both give your AI a memory. The difference is what survives: Mem0 extracts facts and discards the conversation. Engram keeps the conversation — verbatim, permanent, searchable from every AI tool you use.
| Engram | Mem0 | |
|---|---|---|
| What gets stored | Every word, verbatim — the full transcript | LLM-extracted facts, not the full transcript |
| What you can recall | Exact quotes, full context, months later | Compact summaries of what was said |
| Works inside ChatGPT / Claude | Yes — one-click OAuth connector | Via API integration you build |
| Cursor / Claude Code / Windsurf | Copy-paste MCP config, ~2 minutes | Via API integration you build |
| Import your ChatGPT history | Yes — one upload, deduplicated | — |
| Setup required | Connect and say “remember this” | SDK/API integration |
| Pricing | $9/mo flat (free tier: 10,000 messages) | Usage-based plans |
| Self-hosted option | No — hosted only | Yes |
Why verbatim matters
Tell your AI “I prefer TypeScript over Python for backend work” and Mem0 stores a fact like { "preference": "TypeScript for backend" }. Compact — but the reasoning, the caveats, and everything around it aren't part of the stored fact. Six months later you can recall that you preferred TypeScript, but not why, or what constraints drove the decision.
Engram stores the whole exchange. Ask “what did we decide about the backend language, and why?” and you get the actual conversation back — every word, with context. The conversation isthe knowledge base; summarizing it first means deciding in advance what will matter later. Nobody's good at that.
Connect the tools you already use
Mem0 is a developer library — you integrate its API into an agent you're building. Engram works out of the box with the AI you already use every day:
- ChatGPT & Claude — one-click OAuth connector, no API key to paste
- Cursor, Claude Code, Windsurf, VS Code — copy-paste MCP config, about two minutes
- One shared memory — save in ChatGPT, recall in Cursor; nothing to re-explain
- REST API included on paid plans when you do want to build with it
When Mem0 is the better fit
Fair's fair: if you're building an agent pipeline around OpenAI function calling and want compact extracted facts, or you need to self-host your memory layer, Mem0 is a strong choice. Engram is hosted-only by design — zero infrastructure, but not for teams that must run everything in-house.
