What You’re Seeing

The live demo runs entirely in your browser - no API keys, no backend, no install. Left panel (Agent Feed): A simulated AI agent processes a stream of events - user preferences, news headlines, system events, and agent observations. Every 1.2 seconds, the agent generates a mock embedding and writes it to an in-memory Recall instance running in the browser. Right panel (Memory Inspector): The Inspector updates live as the agent writes. You’ll see:
  • Stats bar ticking up as memories are added
  • Memory list with the latest memory appearing at the top
  • Merkle Timeline growing with each write
  • Verify badge showing the integrity state

​
Interacting with the Demo

​
Add Your Own Memory

Type any text in the input bar and click Send (or press Enter). The text gets embedded using a deterministic mock embedder and written to the collection. Your memory appears in the feed with a distinct marker.

​
Query Mode

Click Query to toggle query mode. In this mode, typing text runs a similarity search against all stored memories and shows the top-5 results with their cosine similarity scores.

​
The Tamper Demo

This is the most powerful demonstration of why cryptographic verification matters:
  1. Click Tamper - this corrupts the most recent memory vector with garbage values
  2. Watch the Verify badge flip from ”✓ verified” to ”! unsynced”
  3. Click Restore - the original vector is restored
  4. The badge flips back to ”✓ verified”
This shows that even a single corrupted vector is immediately detectable through the Merkle tree. In production, the root lives on Solana - making tampering not just detectable, but provable to anyone.

Technical Details

  • No WASM dependency - the demo uses a pure JS cosine similarity engine for maximum browser compatibility
  • Mock embeddings - deterministic 64-dimensional vectors generated from text (same text = same vector)
  • 50 pre-written events - cycled through by the agent loop
  • Everything is ephemeral - refresh the page to start fresh
