ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity โ€” no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

The 7 Best Note-Taking Apps for Programmers and Coders
Quiver is yet another app like the two above: you can mix and match text (in both Markdown and LaTeX formats) with embedded code inside notes. However, Quiver has a dedicated code editor right inside the app thatโ€™s cleaner and more responsive than its competitors.

Ask HN: Favorite note-taking software?
For anything more technical I use Quiver which supports MarkDown, code with pretty printing, LaTex and diagram markup, but it doesn't have an iPad editor (just reader).
