MemoryLake for ChatGPT
Long-term memory for ChatGPT — across sessions, devices, and even other AIs.
Why ChatGPT needs MemoryLake
ChatGPT's built-in Memory feature stores a few dozen facts. The practical limits hit fast:
- Capacity is small. Entries get auto-trimmed once you cross a threshold.
- Coherence is weak. Complex multi-chat context almost never survives.
- Lock-in is total. Memory works in ChatGPT and only ChatGPT.
- Control is shallow. You cannot precisely manage what it remembers or forgets.
That is fine for casual use. It is not enough if you actually rely on ChatGPT as a daily working assistant.
What you get
Real long-term memory
Hundreds or thousands of facts, conversations, files — auto-loaded at the start of every chat.
Multimodal capture
Save images, PDFs, screenshots, tables — searchable later by natural language.
Cross-device sync
Phone, laptop, tablet — same memory, automatically.
Cross-AI portability
The same memory works in Claude, OpenClaw, and any MCP-compatible tool. Switch AIs without losing context.
Full control
Edit, export, or delete any memory from a clean dashboard. Your data, your rules.
Privacy by architecture
Triple-party encryption — even MemoryLake cannot read your data.

How it differs from ChatGPT's built-in Memory
| ChatGPT Memory (native) | + MemoryLake | |
|---|---|---|
| Capacity | A few dozen facts | Thousands of memories |
| Modalities | Text only | Text, images, files, tables |
| Cross-chat coherence | Limited | Full |
| Cross-device sync | Inside OpenAI account | Independent of OpenAI |
| Cross-AI portability | None — ChatGPT only | Works in Claude, OpenClaw, MCP tools |
| Edit / export / delete | Limited UI | Full dashboard control |
| Encryption model | OpenAI-managed | Triple-party (architecturally inaccessible) |
They coexist — there is no need to disable ChatGPT's native Memory. Use both.
What people use it for
"Auto-loaded my ongoing project context every time I opened a new ChatGPT chat."
"Switched devices throughout the day; memory stayed in sync everywhere."
"Reviewed and edited remembered facts in a clean dashboard — no more guessing what ChatGPT thinks it knows."
FAQ
Will OpenAI see my MemoryLake data?
Only the snippets that get injected into your specific prompt. The full memory store stays on MemoryLake's infrastructure, not OpenAI's.
Is this against OpenAI's terms of service?
No. The browser extension only injects context into prompts you send — functionally identical to copying notes into a chat manually.
Does it work with GPT-4o, o1, and o3?
Yes — works with every ChatGPT model, including the reasoning models.
Can I use this with Plus and Pro subscriptions?
Yes — every ChatGPT subscription tier is supported.
Does it work with the ChatGPT mobile app?
Browser extensions work in mobile Safari and Chrome. A native iOS/Android app integration is on the roadmap.
Can I export or delete my memory?
Yes. Full export and full deletion are available from your dashboard at any time.
