Artificial intelligence waifu: AI Companions

By Blog
Yes, Cursor AI has a built-in "Memories" feature designed specifically to track and retain project context and key decisions across different conversations and sessions. How Cursor AI Manages Memory By default, without specific memory features enabled, the AI's "working memory" is limited to the current chat session's context. However, the "Memories" system overcomes this limitation through the following mechanisms: Automatic Context Retention: A separate, "sidecar" AI model monitors your conversations and suggests key details or decisions to save as memories. Once approved, the AI can recall this context later, eliminating the need to repeat yourself. Rules and Memory Files: Memories are often stored as structured Markdown files within a specific project directory (e.g., .cursor/rules), which can be version-controlled with your code. The AI automatically injects the content of these files into the context for every relevant operation, ensuring consistent behavior according to project guidelines. Model Context Protocol (MCP) Integration: Cursor integrates with external tools and community projects (like Basic Memory or the Pieces connector) via the MCP to enhance its long-term memory capabilities. These integrations allow the AI to access a persistent, queryable knowledge base derived from your entire workflow history, project files, and even external data like Slack messages or Jira tickets. Codebase Indexing: The AI creates embeddings (numerical representations) of your entire codebase, which allows it to perform semantic searches and understand the project's architecture without needing the full code in every prompt. In summary, while basic AI models are often stateless, Cursor provides robust, explicit features to ensure the AI retains knowledge across sessions, acting as a more consistent and informed pair programmer. You can manage these settings to tailor how much context is shared and retained using the Cursor documentation on Data Use & Privacy and Codebase Indexing

In the ever-evolving journey of artificial intelligence, one particularly fascinating niche has emerged at the intersection of technology, psychology, and pop culture: the rise of the AI waifu. Once a term bound to anime fandoms and virtual fantasy, the notion of creating emotionally intelligent, digital companions has leapt into the realm of plausibility…
