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.

CodeKitHub's answer:
Compared to single-purpose sites like JSONFormatter.org or CodeBeautify that only handle one task, CodeKitHub covers the same ground plus image, PDF, QR, and calculator tools in one place — useful if you regularly switch between different tool types during a workday.
Unlike FreeFormatter (which recently shut down its service), CodeKitHub's tools require no backend at all — everything runs as static, client-side JavaScript, so there's no server cost pressure driving ads, paywalls, or future shutdowns of the kind that killed similar sites.
If you need a tool site in a language other than English — Spanish, French, German, Japanese, Korean, Chinese, and others — CodeKitHub is one of the few free tool sites that actually localizes the full interface rather than just running it through machine translation on top of an English-only tool.
CodeKitHub's answer:
CodeKitHub serves two overlapping groups:
Traffic data shows both groups in practice: technical tools (QR generator/decoder, Base64 encoder, JSON tools) draw developer-heavy referral sources like Hacker News and ChatGPT, alongside broader organic search traffic for everyday utility tasks.
CodeKitHub's answer:
CodeKitHub started as a small set of browser-based developer utilities and grew into a 120+ tool collection covering JSON formatting, encoding, image/PDF processing, calculators and more. The core principle from the start was that every tool should run entirely client-side — no backend, no data leaving the user's browser — which keeps the tools fast, private, and cheap enough to run without ads getting in the way. The site has since expanded to 13 languages to serve users beyond English-speaking markets.
