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.

Nudgify is a Social Proof and FOMO notifications app that makes your website more engaging, boosting sales and sign-ups.

What Makes Nudgify Special?

Nudgify uses real data to show visitors important context (like who has viewed a page and what people have been buying). Because Nudges show things people don't usually get to see online, they increase engagement without compromising user experience. You simply pick from a library of Nudges to display recent sales ("Sales Pop"), low stock warnings (FOMO) and reviews - all in real-time.

How Does Nudgify Boost My Website's Revenue?

Nudgify increases your conversion rate by showing visitors they can trust your website and creating a sense of urgency.

  • Social Proof Nudges highlight how popular your products are
  • Google and Trustpilot Review Nudges add testimonials to any page
  • FOMO Nudges give visitors a reason to take action immediately
  • Custom Nudges make your website user-friendly

Using a combination of Social Proof, FOMO and Custom Nudges, you can build trust, stop leads procrastinating and reduce funnel exits.

How Does Nudgify Create Social Proof and FOMO In Real-Time?

It's all automatic! Once you have set up your data feed, by integrating Nudgify with another app or connecting it with one of your website's forms, every interaction with a visitor becomes powerful Social Proof.
