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.

Https://syncthing.net/ <- like this :) Free, opensource, works on computers and phones, can in most cases puncture nat, supports local discovery (lan, multicast). No googles, no dropboxes, no clouds, no AI training, no "my kid likes the wrong video on youtube, now our whole family lost access to every google account we had, so we lost everything, including family photos", just sync!

Syncthing is a decentralized, peer-to-peer file sync tool. Devices connect directly to each other โ no central server. It does one thing: keep folders in sync across devices. It does this exceptionally well, with block-level delta sync and strong encryption. - Source: dev.to / 5 months ago
This will let you download all of your photos that already exist on iCloud Photos. Going forward, youโd want to set up some other way to sync photos you take from your phone to your other devices. I can personally recommend Synology Photos for simplicity[1], or Immich[2] for an open-source (and in my opinion, slightly better) alternative you can run on any hardware, if youโd like to set up an always-on NAS. These... - Source: Hacker News / 6 months ago
