What is Memory?

Memory is a way to store information in the model’s context. This information can be used improve the model’s responses to questions or to perform tasks in the future. Additionally, it allows you to carry over context from one conversation to the next. Memory example image Some examples of how you can use memory:
  • Remember certain details about your job
  • Share a preference for a specific style of writing
  • Remember your name and other personal details
All your memories are stored in your account, and are available to you in all your chats.
Memory is not available when using Agents. When you’re working with an Agent, the memory feature is disabled.

​
Usage

To use memory, you need to enable it in your settings. Go to your account settings, then the “Preferences” tab. There you can enable chat memory in the capabilities section.

​
Memory Operations

Langdock supports three memory operations that allow you to manage your stored memories directly through conversation.

​
Saving Memories

To save a new memory, simply tell the model what you’d like it to remember. You can use natural language like:
  • “Remember that my name is Alex”
  • “Note that I prefer concise responses”
  • “Store this: I work in the marketing department”
  • “From now on, keep in mind that I like bullet points in summaries”
The assistant will automatically identify information worth saving based on:
  • Explicit requests to remember something
  • Information that will be useful in future conversations
  • Details that will help personalize responses going forward
Good memories are generalizable (useful across different contexts), relevant (will improve future responses), and long-lasting (true for months or years, not just temporary facts).
Example memories the model might save:
  • “Prefers concise, no-nonsense confirmations”
  • “Works in sales at a B2B SaaS company”
  • “Favorite programming language is Python”
  • “Boss is named Sarah Chen”

​
Updating Memories

To update an existing memory, provide the model with new information about something it already knows. You can say things like:
  • “Update my job title - I’m now a Senior Manager”
  • “Actually, my favorite color is green, not blue”
  • “Change my preference: I now want detailed explanations instead of brief ones”
The assistant will find the relevant memory and update it with the new information.

​
Deleting Memories

To delete a memory, ask the model to forget specific information:
  • “Forget my old job title”
  • “Delete the memory about my project deadline”
  • “Remove the note about my preferred meeting times”

​
Inspect and edit memories

You can view and manage all your memories by going to the “Memory” tab in your account settings. There you can:
  • View all stored memories
  • Edit existing memories to adjust wording
  • Delete memories you no longer need
Edit memories in settings

​
Limitations

Memory limit: You can store a maximum of 50 memories at a time. If you reach this limit, you’ll need to delete some older or less relevant memories before saving new ones.

​
What NOT to store in memory

The assistant is designed to avoid storing certain types of information unless you explicitly request it:
  • Overly personal details that could feel intrusive
  • Short-lived facts that won’t matter soon (like “I have a meeting tomorrow”)
  • Random details without clear future relevance
  • Redundant information that’s already stored
  • Sensitive personal data such as:
    • Health or medical information
    • Precise location data (street addresses)
    • Political affiliations or religious beliefs
    • Criminal record details
If you do want to store sensitive information, you can explicitly ask the model to remember it, and it will respect your request.
