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.

  • keep making extremely dumb mistakes?
    Some companies use things like CoderPad or Google Docs (yes, Google really used to use Google Docs). Those don't let you run the code either so they're more like whiteboards. Source: over 3 years ago
  • Coding Test for Embedded Engineering Internship - not a fan of high level coding
    I am a CS major with a computer engineering minor. I want to prepare myself to apply for an Embedded Engineering Internship. The interview process includes a coding task on coderpad.io, I have no clue what to expect - what kind of questions will be asked for an embedded internship? I say this because coding embedded systems is rather different from "regular" coding in practice. High level v low level. Source: over 3 years ago

  • Is this a system design interview?
    I am prepping for a final round interview for a frontend position at a medium size company. The recruiter gave me some information about one of the coding rounds and I am not entirely sure what to expect. The description says I will be building a fullstack web app, and the goal is to test my frontend and backend knowledge, and get a working solution. I will be using https://excalidraw.com/ in addition to... Source: almost 4 years ago
  • Live code screening practice?
    The specific target interview format I have in mind is via a shared, live editor (e.g. https://coderpad.io/) and a video link, lasting ~1hr. The practice format might be more like 45min for the interview followed by 15 - 30min for feedback and discussion. Doing two of those back to back so both of us get our chance in the hot seat could be exhausting, so this might be two separate sessions. Source: almost 4 years ago
