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.

    Love this tool, super easy, reasonably priced and GREAT customer service!

    Before deciding to go with a platform for running promotions, we did a ton of research and looked at all the usual suspects. We weren't familiar with SweepWidget, though decided to give it a chance. We couldn't be more happy with our decision. It's reasonably priced with a TON of features, and the customer service is well beyond what we expected. Give it a chance like we did, you won't regret it.

    SweepWidget is an awesome organizational tool!

    I am Laura the garden blogger behind Raise Your Garden. I switched to SweepWidget and what a game-changer! Not only does SweepWidget help me effectively organize all entrants, but it is super easy to use! In under 5 minutes I am able to complete another giveaway form. My loyal readers are equally thrilled with how easy it is to enter my contests and verify their entries. Itโ€™s a great alternative to Gleam! My favorite part of SweepWidget is the โ€œCreate Your Own Optionโ€ button that allows me to add any type of entry with ease. Now I use SweepWidget to run all my contests and I usually have one per week so it's a tool I'm using constantly! I don't have time for an inferior host for my contests and SweepWidget is the creme de la creme!
