Memory

How AI systems store and recall information from previous conversations or interactions to provide contextual responses.

What is Memory?

Memory in AI is how models remember context from earlier in a conversation or across sessions.

Most AI chatbots only remember what's in your current chat window. Once you start a new conversation, they forget everything. Some newer systems can persist memory across sessions, remembering your preferences, project details, or previous discussions.

Builders use memory features to avoid repeating context every time. Instead of re-explaining your tech stack in every chat, the AI just knows you're using Next.js and Supabase. ChatGPT Plus and Claude both offer memory features, though they work differently.

Memory can be session-based (just this chat) or persistent (across all chats). Some tools let you manually add or remove memories. Privacy matters here since these systems are storing your information.

Good to Know

Session memory only lasts for the current conversation
Persistent memory carries context across multiple chats and sessions
You can usually view, edit, or delete what the AI has stored about you
Memory reduces repetitive context-setting in ongoing projects
Different AI tools handle memory differently - some auto-save, others require manual input

System Prompt

Instructions that define an AI's behavior, personality, and constraints before it responds to user queries.

Context Window

The amount of text an AI model can remember and process at once, measured in tokens. Bigger windows mean longer conversations and documents.

Claude Skills
