Extension Features

The CORE extension currently works with ChatGPT and Gemini (more integrations coming soon). The CORE logo appears directly inside your chat interface, giving you instant access to memory features: Extension
  1. Auto Sync Toggle this on and CORE automatically saves your conversations to memory. Every brainstorming session, solution, or insight gets captured for future recall across all your tools.
  2. Add Space Context Inject pre-built project summaries directly into your prompt. Create spaces in CORE for different projects or topics (e.g., “CORE Features,” “Marketing Strategy”), then instantly add that full context to any conversation without retyping.
  3. Improve Prompt Powered by CORE’s Deep Search, this analyzes your prompt, searches your entire memory, and automatically enriches it with relevant context—making AI responses smarter and more personalized.
