Does DeepSeek or Grok Have Memory? How They Work and How to Share Them
What DeepSeek and Grok Remember Between Chats, and How to Keep One Memory Across AI
Disclosure: Membase is our product. We cover what DeepSeek and Grok do on their own first. Facts were checked in November 2026; neither company publishes a detailed memory guide, so where settings vary by app or region, we say so.
Quick answer
- DeepSeek: no cross-chat memory. It remembers what you said earlier in the same chat, but each new chat starts fresh. There’s no saved-memories feature or custom instructions.
- Grok: yes. Grok can remember details from your past conversations and use them to personalize answers. You can turn memory off, have it forget specific memories, or use Private Chat.
Neither one shares memory with ChatGPT, Claude or Gemini. To keep one memory across all of them, add a shared memory such as the Membase Chrome extension.

Does DeepSeek have memory?
Not between chats. At the time of writing, DeepSeek hasn’t released a memory feature.
| DeepSeek | |
|---|---|
| Within one chat | Remembers earlier messages, up to the model’s context window |
| Between chats | No. A new chat knows nothing about earlier ones |
| Saved memories | No |
| Custom instructions | No |
| Chat history | Saved to your account, where you can view and delete it, but new chats don’t use it |
Users have asked for persistent memory on DeepSeek’s GitHub, but DeepSeek hasn’t announced it.
For developers: DeepSeek’s chat API is stateless. The server doesn’t keep your conversation, so your app has to send the earlier messages with every request.
How to make DeepSeek remember you
Until DeepSeek adds memory, you have three options:
| Option | How | Trade-off |
|---|---|---|
| Paste a context block | Keep a short note about you and your project, and paste it at the start of each new chat | Manual every time, and goes out of date |
| Stay in one long chat | Keep working in the same conversation | Very long chats run past the context window, and older messages drop out |
| Use a shared memory | Add a tool that saves your DeepSeek chats and brings the relevant parts into new ones | Needs an install |
A context block that works:
About me: I'm a product marketer at a B2B software company.
Current project: launching a Chrome extension in Q1.
How I like answers: short, with bullet points, in British English.
Don't: suggest paid tools unless I ask.
Does Grok have memory?
Yes. Grok’s memory launched in April 2025. When it’s on, Grok can draw on your earlier conversations to make answers more personal: for example, recommendations that fit what you told it before.
Two things shape what Grok knows about you:
| Source | What it is |
|---|---|
| Memory of past conversations | Details from your earlier Grok chats |
| Your X data (Grok on X) | If you allow it, X can share data such as your public posts, interests and how you use Grok to personalize your experience |
Memory first launched on grok.com and the Grok iOS and Android apps, and wasn’t available in the EU or UK at launch. Availability may differ by app and region, so check your own settings.
How to control Grok memory
| To | Do this |
|---|---|
| Turn memory off | Open Settings > Data Controls in Grok and turn off the memory option |
| Forget a specific memory | When a response used memory, you can see which memories it drew on and choose to forget them |
| Chat without memory | Start a Private Chat (the ghost icon). Private chats aren’t kept in your history and are deleted within 30 days |
| Delete all conversations | In Settings > Data Controls, delete all conversations. Deletion can take up to 30 days |
| Stop X data personalizing Grok | On X: Settings > Privacy & Safety > Data sharing and personalization > Grok & Third-party Collaborators, then deselect “Allow X to personalize your experience with Grok” |
Menu names can differ slightly between grok.com, the apps and Grok on X.

Share one memory across DeepSeek, Grok and other AI
Whether your AI has memory or not, it only remembers inside itself. If you use DeepSeek for one thing, Grok for another and ChatGPT or Claude for the rest, each one knows a different slice of you.
The Membase Chrome extension saves your conversations in DeepSeek, Grok, ChatGPT, Claude, Gemini and Kimi into one memory, and brings the relevant parts into whichever chat you’re in.
- Add the Membase Chrome extension (the Chrome Web Store may still list it as Unibase Memory).
- Sign in, or create a free account at app.membase.com.
- Chat as usual. What you told Grok yesterday is there when you open DeepSeek today, so DeepSeek finally starts with context.
| DeepSeek alone | Grok alone | With Membase | |
