ChainMemory gives your AI agents persistent memory that belongs to YOU — 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 — 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.

  • 10 Best WYSIWYG Editors for Web Developers in 2026
    TipTap is a headless WYSIWYG editor built on top of ProseMirror. It gives developers full control over the UI while handling complex editing logic under the hood. This makes it a strong fit for highly customized interfaces. - Source: dev.to / 7 months ago
  • Top 5 Page Builders for React
    While Storyblok and Builder.io offer full-page editing experiences with structured CMS capabilities, Tiptap takes a different approach. It’s not a traditional page builder but rather an embeddable headless editor built on ProseMirror. This means that instead of giving you a predefined UI to work with, it provides the underlying logic, leaving you in full control of the interface, interaction and level of... - Source: dev.to / over 1 year ago
  • Ask HN: How to integrate a Blog system into my NextJS app
    > One thing I learned is that you should lean towards letting non-technical people choose their own tools like why we largely let developers choose their own tools. IMHO: I think a more sustainable variant of this (for your own sanity) might be to ask them which tool(s) they like and then take some time to understand WHY. But then instead of just letting them use those directly, you would either vet them first... - Source: Hacker News / almost 2 years ago
  • Open Source Contribution: Round 2
    However, after doing some extensive research, I realized that almost none of them were compatible with Svelte, and those that were did not offer what I was looking for. That is, until I found tiptap, which is a headless wrapper around another WYSIWYG editor called ProseMirror. However, ProseMirror is very low level, and tiptap is super Svelte friendly! - Source: dev.to / almost 2 years ago
  • Word-like HTML inline edit with design mode
    I love how Trix [0] and (I think) ProseMirror [1] work in that regard: it does use contenteditable, but every edit you make is applied to an internal model instead, then the editor state is updated back from the model.
