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.

    Also see https://wordpress.org/openverse/ it allows you to filter to only public domain images. - Source: Hacker News / over 3 years ago
  • Google Broke Image Search for Creative Commons and Hardly Anyone Noticed
    Thanks for the HN treatment. As a followup piece, a Google response of this being "a bug". Followup story, my return rate for CC licensed images of "dog" went from 3 to 13. More than that, license info is not displayed (only linked), is frequently wrong, and photo credits often given to the site, not the creator of the image. https://cogdogblog.com/2022/10/google-cc-image-search-better-sad/ Try Openverse for much... - Source: Hacker News / almost 4 years ago
  • Google Broke Image Search for Creative Commons and Hardly Anyone Noticed
    Last time I've checked, Creative Commons had their own search for things under their licenses. But now apparently that project got transferred to WordPress and is now named Openverse: https://wordpress.org/openverse/?referrer=creativecommons.org Anyways, I'd argue that's the most comprehensive database of CC-licensed works. - Source: Hacker News / almost 4 years ago
  • Best Practices for Attribution
    > In addition, a searchable database of Creative Commons works would be a welcome addition to the Internet. Openverse is a CC search engine with 600 million items: https://wordpress.org/openverse/ And of course, Google Images supports CC search for images. - Source: Hacker News / almost 4 years ago
