Stop explaining yourself to every AI.
ChatGPT, Claude, and Gemini each keep their own memory. Here is what each tool remembers natively — and how to share one authored context across all three.

Why you repeat yourself across ChatGPT, Claude, and Gemini
No major AI assistant natively shares memory with competitors. Google's March 2026 import tools help you migrate intoGemini — not keep context live across every tool. Claude and OpenAI have export flows, but each platform's memory stays in its own silo.
If you use ChatGPT for drafting, Claude for analysis, and Gemini on mobile, you are maintaining three separate summaries of who you are — or re-explaining from scratch each time.
What each tool remembers natively (and what it doesn't)
| Platform | User-written layer | Auto memory | Workspace |
|---|---|---|---|
| ChatGPT | Custom Instructions | Memory Summary (Dreaming synthesis) | Projects with project-only memory option |
| Claude | Project instructions | Global Memory (24h synthesis, standalone chats) | Projects with separate project memory |
| Gemini | Personal context / instructions | Memory from past chats (Keep Activity on) | Gems (memory not available in Gems) |
Each layer is useful inside its own ecosystem. None of them gives you one plain-text record you authored, inspect line by line, and share everywhere without an import/export step.
Option A: Native setup per platform
If you primarily use one tool, native memory may be enough. Configure each platform's standing instructions and memory toggles:
- ChatGPT: Settings → Personalization → Custom Instructions + Memory
- Claude: Settings → Capabilities → Memory; Projects for client work
- Gemini: Settings → Personal Intelligence → Memory toggle; instructions for standing rules
Expect to maintain three summaries as your work changes — and accept that inferred memory may not match what you would have written yourself.
Option B: One authored context file + private link
Write your context once in plain text. AIMemLink serves it at a private, unguessable URL. The same link works across ChatGPT, Claude, Gemini, and any future model with web access — no extension, no import wizard, no vendor lock-in.

How to wire the link into each assistant
- Write your memory on AIMemLink.
- On your dashboard, tap ChatGPT, Claude, or Gemini under Talk to your AI — your instruction snippet copies automatically.
- For lasting setup, paste the snippet into each tool's standing instructions (Custom Instructions, project instructions, or Gemini personal context).
- Start a new chat and ask a question only your memory can answer.

When native memory is enough — and when it isn't
Native memory works when you use one tool, trust inferred summaries, and do not need to audit what is stored. It falls short when you switch tools, want inspectable authorship, or need the same biography and constraints everywhere without re-importing.
AIMemLink is not "better memory than ChatGPT." It is a vendor-neutral record you write, read, and update — while each platform's native memory handles what you are comfortable letting it infer.
Keep it current
Built-in memory infers and lags. Authored memory updates on your schedule — edit the dashboard, text the Telegram bot when life happens, and rotate your link if it leaks. See our guide on keeping AI memory current as your work changes.
