ChatGPT Memory personalizes ChatGPT — and stays locked inside ChatGPT. Palim is an encrypted memory layer that works across ChatGPT, Claude, Cursor, Claude Code, Perplexity, and any MCP-compatible tool.
If ChatGPT is the only AI tool you use, its built-in memory is probably enough. If you switch between several AI tools, Palim gives all of them one shared memory: decisions, project context, and preferences follow you from tool to tool instead of starting from zero in every new chat.
| Feature | Palim | ChatGPT Memory |
|---|---|---|
| Works in | ChatGPT, Claude, Cursor, Claude Code, Perplexity, and any MCP-compatible client | ChatGPT only |
| Cross-tool context | Yes — one knowledge base shared by every connected tool | No — memories never leave ChatGPT |
| How memories are created | Explicit and on your terms — “Save this session to Palim” or natural prompts | Automatic, curated by OpenAI in the background |
| Data control | Your own knowledge base, hosted in the EU (Frankfurt) | Stored and managed by OpenAI |
| Encryption at rest | AES-256-GCM with a unique per-user key | Provider-managed |
| Search across past sessions | Full-text search across all saved sessions | No full-text search of chat history via memory |
| Price | Free — no credit card required | Included in ChatGPT |
ChatGPT Memory requires zero setup. It automatically remembers your tone, preferences, and recurring topics, and OpenAI keeps improving how memories are curated in the background. For personalization inside ChatGPT it is genuinely good — and it is included in every plan.
Vendor memory is a retention feature, not a portable record of your work. Everything ChatGPT learns about you stays with OpenAI: the preferences you taught ChatGPT never reach Claude, and the architecture decision you discussed yesterday is invisible to Cursor.
In 2026 every major assistant — ChatGPT, Claude, Gemini, Grok — ships cross-session memory, and none of them share it with the others. That is by design. If you work across tools, you become the bridge: copy-pasting context, re-explaining constraints, rebuilding the same setup in every new chat.
Palim is a hosted MCP (Model Context Protocol) memory server. You connect your AI clients to one endpoint (https://api.usepalim.com/mcp) — setup takes about two minutes. From then on you can save sessions, decisions, and memories from any connected tool and recall them from any other.
Your data lives in your own encrypted knowledge base: AES-256-GCM at rest, a unique key per user, hosted in Frankfurt (EU). You can export or delete everything at any time; after account deletion, all personal data is removed within 30 days.
This is not either/or. Keep ChatGPT Memory for in-app personalization, and use Palim as the project memory that travels with you — across ChatGPT, Claude, Cursor, and whatever tool you adopt next.
No. ChatGPT Memory is not portable — it only works inside ChatGPT. Palim bridges this gap by storing your context in a tool-independent knowledge base that every MCP-compatible client (Claude, Cursor, Claude Code, Perplexity, and ChatGPT itself) can read and write.
They serve different purposes. ChatGPT Memory personalizes ChatGPT; Palim gives all your AI tools one shared project memory. Most users keep both: built-in memory for personalization, Palim for portable context.
Connect ChatGPT to Palim's MCP endpoint, then say “Save this session to Palim” in any conversation worth keeping. The session is stored with a summary, decisions, and tags, and becomes searchable from every other connected tool.
Yes. Palim is free to use and includes chat storage, full-text search, the distilled knowledge profile (Brain), and encryption — no credit card required.
Single-tool users: stick with ChatGPT Memory. Multi-tool users: ChatGPT Memory cannot follow you, and that is exactly the job Palim was built for — one encrypted, searchable memory shared by every AI tool you use.
