What is this feature?

Adaptive memory allows your Playlab apps to selectively remember things you instruct it to remember, impacting future interactions users have with your app. Memory turns on as soon as you write memory instructions in the builder’s Memory pane. There’s no separate setting to enable.
Using adaptive memory will change the way your app functions as it will include what it remembers into the chat.

​
Rationale for the feature

This feature enhances the capabilities of your Playlab apps in several key ways:
  • More Natural Conversations: AI will maintain context and have more coherent discussions
  • Better Understanding: Enables AI to grasp nuanced meanings and references from earlier in the conversation
  • Improved Assistance: Allows AI to build upon previous responses and refine its help based on user feedback
  • Context Awareness: Helps AI understand when previous information needs to be updated or modified

How do I set up adaptive memory?

1

Open the Memory pane

In the app builder, click Memory in the toolbar on the right side, just below References.
2

Write your memory instructions

Describe what you want your app to remember about each user, such as their grade level or the topics they find challenging.

Test memory in the preview

Start a session in the builder preview and chat with your app. After each response, the app updates what it remembers. The Your memory contents section at the bottom of the Memory pane shows what the app has saved about you, so you can check it against your instructions.Click the refresh icon to update the memory from your recent session, or the trash icon to delete it and start over.The Your memory contents section of the Memory pane, with refresh and delete icons next to the heading and a bulleted list of saved details

Know what users see

Signed-in users see a Save my progress toggle on your app’s start screen. It’s on by default, so the app remembers them across sessions. Users can switch it off for a session, or click the pencil icon next to it to view or delete what the app has saved about them.An app start screen with the Save my progress toggle on
Memory only works for signed-in users. Anonymous users don’t see the toggle, and nothing is saved for them.

Tips for Creating Effective Memory Instructions

​
Best Practices

Clearly define the categories of information your app should retain. Vague instructions may result in remembering too much irrelevant information or missing important details.
Not all information needs to be remembered. Focus on the details that will have the most significant impact on future interactions.
As your app evolves, revisit your memory instructions to ensure they’re still capturing the most relevant information for your users.
Analyze how memory affects actual user interactions and adjust your instructions based on what works best in practice.

​
Practical Applications

Remember learning progress, difficult concepts, and preferred explanatory styles to provide increasingly tailored educational content.
Track project stages, recurring tasks, and work preferences to offer more relevant assistance over time.
Remember stylistic preferences, past projects, and creative goals to provide more consistent and helpful creative guidance.
Track progress, habits, challenges, and preferences to provide more personalized support and recommendations.

​
FAQ

While user profiles provide static information set up in advance, adaptive memory dynamically captures and retains information that emerges during conversations. Both features can complement each other for a more personalized experience.
Yes, your memory instructions guide what the AI remembers. While testing, you can view, refresh, or delete your own memory in the Your memory contents section of the Memory pane. Users can view or delete what an app remembers about them with the pencil icon next to Save my progress, or switch the toggle off for a session.
Each user has one memory per app, kept as a short list of details that the app updates after each response. Focus on quality over quantity by instructing the AI to remember only the most impactful details.
Memory information is stored as part of your app’s data. For specific privacy concerns, please refer to our privacy policy or contact support.

​
Important Considerations

Be cautious about including Personally Identifying information in your memory instructions. Avoid instructing the AI to remember last names, addresses, contact information, and other sensitive information that you would not be comfortable sharing.
