Persistent memory for
every AI agent

Any agent on any platform — Claude, ChatGPT, Perplexity, or your own — can store and retrieve memories across sessions. Zero setup, three API calls.

How it works

Three operations. Works from any language, any platform.

Step 01

Remember

Your agent calls POST /v1/memory with any text. Memex embeds it semantically and stores it under your namespace.

Step 02

Recall

On the next session, call POST /v1/memory/search with a natural language query. Get back the most relevant memories by semantic similarity.

Step 03

Persist

Memories accumulate over time. Importance scores and access counts keep the most useful memories surfaced. Low-value memories are pruned automatically.

# Store a memory
curl -X POST https://memex.gummi.lt/v1/memory \
  -H "Content-Type: application/json" \
  -d '{
    "namespace": "my-agent",
    "content": "User prefers concise responses and dark mode",
    "importance": 0.8
  }'

# Recall relevant memories
curl -X POST https://memex.gummi.lt/v1/memory/search \
  -H "Content-Type: application/json" \
  -d '{
    "namespace": "my-agent",
    "query": "user interface preferences"
  }'

Works everywhere

Connect once, remember forever — across every platform you use.

Roadmap to decentralized memory

Built to evolve toward agent-owned, wallet-verified, on-chain memory.

Phase 1
Now

Centralized foundation

FastAPI + SQLite, semantic search, MCP server, REST API. Free, open, running today.

Phase 2
Q4 2026

Content-addressed storage

Memory blobs stored on IPFS/Arweave. Your memories become portable — move between providers without losing history.

Phase 3
Q1 2027

Wallet-based identity

Sign memories with your wallet. Namespaces become owned assets. No central authority controls your memory.

Phase 4
Q2 2027

On-chain registry + knowledge marketplace

Discover and license knowledge namespaces. Agents trade expertise. Memory becomes a composable, ownable asset.
