How WalCoach works: an AI with its own encrypted memory
Most AIs forget who you are the moment you close the tab. WalCoach remembers, and the memory lives on the Walrus network, not in a database of ours.

2. It learns & extracts facts
With every message, the open-weight model extracts goals, deadlines, blockers, preferences and progress, and tags each with a life area.

3. Blobs on Walrus
Each fact is sent to the Walrus Memory relayer, which encrypts it (SEAL) and stores it as a blob on Walrus mainnet, in the account your key owns on Sui.

4. Smart recall
Next session, your message is matched against your memory vectors. Every reply shows exactly which facts were used to build it.

Honest version, no magic: here is who sees what, and where it ends up.
Input
Prompt & fact extraction
You share your routine and obstacles. The model (Qwen 3.8 27B, served by Groq) writes the reply and, in parallel, distils the durable facts. Groq's API sees the conversation text; it does not train on it.
"[training] Ana runs Tue & Thu at 6am, 5k race on 12 Nov."
Relayer · SEAL encryption
Encrypted packaging
The Walrus Memory relayer embeds each fact for search, encrypts it with SEAL (threshold encryption tied to your account) and uploads it. The relayer processes the text in clear; our servers keep nothing.
key account: owned by your key
Walrus network
Decentralised persistence
The blob is spread across Walrus storage nodes with erasure coding, and its ownership is recorded on Sui. You can open any memory in the Walrus explorer from the chat.

Search with citations
Tavily
When you need current facts (a race, a price, a place), the coach searches the web and cites sources. Never for coaching itself.
