Go engineering. Practical tools.
APIs, backend systems, and AI-engineered tools — OSINT, security checks, SEO analyzers. And smart contracts you can drive yourself, live on Base Sepolia. Built in Go.
Founders describe a business idea and get a structured, AI-driven viability analysis — market demand, competition, risks — in 10 languages.

The contracts below are live on Base Sepolia right now, and you can drive them yourself.
In the escrow, a seller releases funds with a Groth16 proof of a delivery secret — the secret is never revealed, not even to the contract. When delivery is contested, the case goes to an AI arbiter: it reads the evidence both parties published on-chain, rules, and its full reasoning is written back to the chain verbatim, permanently.
The arbiter's power is bounded by the bytecode. It can credit a pull-payment balance and nothing else — it cannot push funds, cannot touch an escrow that isn't disputed, and cannot revisit one that's settled. That's the part worth looking at: not that an AI made a decision, but that the decision is auditable and the authority is enforced by a contract rather than a policy.
No screenshots, no mock data. Contract addresses are on BaseScan, source is on GitHub, and every settlement is sitting there to read.
Practical tools
Free online tools built and run in-house — from OSINT and security checks to SEO and marketing analyzers.
-
TraceCheck
Trace an email header end to end and see every hop it really took.

Not another AI wrapper.
Every tool here hits real infrastructure — DNS, WHOIS, TLS, raw metadata — before any model reasons over it. Evidence first, interpretation second, and you can verify every signal yourself. Same rule on-chain: the arbiter's authority is whatever the contract grants it, and its reasoning is public record.
