How it works

A quiet guardian, from the inside out.

Ayyaran runs entirely on your device. It thinks the way you do, learns your rhythm, and only speaks up when something is actually wrong.

How it works

Technical, not cold. Precise, not paranoid.

On-device engine

A Rust engine compiled to WebAssembly runs 18 detectors inside the browser tab. Zero network round-trips on the hot path. Zero cloud reads.

Agentic reasoning

Signals compose into situations — not just 'phishing detected' but 'wallet-drain attempt on a fake Uniswap, cross-tab shows your real tab is open, plan: block with typed confirmation + alert your trusted helper.' Every conclusion is inspectable — no hidden model.

Sealed cloud sync

Optional Pro sync uses a pair-code handshake. The server stores only wrapped keys and encrypted envelopes it can't read. Your dashboard decrypts in your browser.

Intelligence, on your side

A small, private AI that thinks before you click.

Ayyaran runs a compact reasoning model directly on your device. It reads context the way you do — page intent, sender history, the shape of a link, the tone of a message — and composes signals into situations rather than raw alerts. It learns your normal rhythm quietly over time, so a fake login page, a drainer contract, or a socially-engineered DM feels obvious the moment it appears. No prompts leave your machine. No model fingerprints your behaviour in the cloud.

Contextual reasoning

Combines page, sender, and clipboard signals into plain-English explanations — 'this looks like a wallet-drainer masquerading as Uniswap' — never a raw score.

Learns your baseline

Builds a private behavioural baseline on-device. The domains you actually use, the wallets you actually approve, the people who actually email you.

Private by construction

Inference runs locally in WebAssembly. No prompts, embeddings or telemetry leave your device — the AI has no cloud to phone home to.
