Notezilla is a sticky notes app for Windows & Phones designed to keep you well-equipped & well-organized. It lets you take quick notes on sticky notes (that look like 3M Post-Itยฎ Notes), right on your Windows desktop & gives you the best sticky notes experience.
With the optional cloud synchronization feature, you can sync sticky notes between computers, access them from any smartphone using our free apps for iPhone/iPad, Android, etc or send sticky notes to any contact across the globe.
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.
