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.

  • How to Summarize PDFs Locally with Open-Source LLMs (No API, No Data Leaving Your Machine)
    You just need a few summaries occasionally. Standing up Ollama, a model, and an extraction pipeline to summarize five PDFs is overkill. If privacy isn't the constraint, a free web tool does it in seconds โ€” ChatPDF and NotebookLM if you don't mind an account, or PDFSummarizer.net if you want no sign-up and formats like EPUB/PPTX handled for you. One caveat that matters specifically because this article is about... - Source: dev.to / 20 days ago
  • Tools I'm Using in 2026 (and what I've stopped using from 2025)
    Last year I was heavily into Perplexity but for most of 2026 I've actually been using NotebookLM a lot more. Perplexity is still useful for just daily news, but when I want to research, when I want to summarise, when I want to learn... NotebookLM all the way. - Source: dev.to / 2 months ago
  • NotebookLM Skills: Give Claude Code a Brain That Doesn't Hallucinate
    NotebookLM already sorted this on Google's side. You upload your sources, Gemini answers only from those sources, every answer comes with citations pointing to the exact passage. The catch was it's browser-only. No API. No way to wire it into your agent workflow. - Source: dev.to / 3 months ago
  • How did I pass the AWS Certified Solutions Architect โ€“ Professional 2026 exam?
    In Notebook LLM, add the information sources you use for studying and use different formats. It currently supports Latin American Spanish. - Source: dev.to / 4 months ago
  • Automating Roadmap.sh into NotebookLM
    Then there's NotebookLM. For me, this is the "holy grail" of studying. You feed it a few links, and it generates these incredibly fun, informative "Deep Dive" podcasts. I started listening to them on my daily commute, and honestly, I've never absorbed complex tech topics faster. - Source: dev.to / 4 months ago
