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.

  • I reached $10,000 in savings for the first time in my life.
    Another vote for treasuriesโ€ฆ theyโ€™re paying 5.4% atm! I found the treasury.gov site to be super clunky and opted to buy my treasuries (6m short-terms) through Public. Itโ€™s been nice to drip any extra money here and there and it definitely adds up fast. Source: about 3 years ago
  • Possible to earn 4-5% on bond/cash-like assets
    HL allow you to buy bonds, and public.com is another major site. Source: over 3 years ago

  • What's the best trading platform except public.com?
    Unfortunately, public.com is region locked to the USA. Its unavailable in my country, so I'm asking for an alternative. Because Glizzlord has been saying that other trading platforms have bad business models and or steal information and sell it, I'm afraid to pick one on my own. Could the interested in stocks here suggest me a platform to start on? Source: over 3 years ago
  • We the Investors Partners.
    Public.com is an app based brokerage- Open To the Public Investments, Inc, that has existed under numerous names for twenty years or so. Public uses Apex for it's clearing house, they put GME and others onto PCO as a result, during the sneeze. They were, purportedly angry about it. They also stepped back from PFOF as of 2/16/21.... Just after the sneeze. And probably just to get out from the shitstorm of hate... Source: almost 4 years ago
