Sitanshu Sinha | Systems that prove their own work

I build systems that prove their own work.Sitanshu Sinha builds agentic software, explained at the system level: closed loops, external verification, honest exits. The flagship is FactLens: a working fact-check pipeline that listens to a video, reads its caption and on-screen text, and checks the claims against the web. It caught a viral reel putting a fabricated quote in a government spokesperson's mouth at 103,478 likes, in about two minutes on a Mac mini. Its sibling, Nudger, judges the media diet privately on the same machine. Eight more systems are documented here, spanning build infrastructure, intelligence systems, and personal systems, alongside a personalised India inflation tracker computed from official MOSPI data.One headline number, very different lives: India's May 2026 CPI is 3.93%, but the official basket runs at about 3.9%, a metro renter's basket at about 3.4%, and a wedding saver's at about 7.3%. Set your own spending mix at the inflation tracker.Explore

The eight systems

An agentic operating system: A single backend that coordinates specialized capability modules behind one API.

A constitution for AI-built software: A written spec before code, a mechanical exit gate, and a second reviewer who cannot edit.

A narrative-intelligence engine: Watches many public surfaces at once, classifies brand-relative, and abstains when the evidence is thin.

A synthetic-audience simulator: A weighted panel of synthetic personas estimates reaction, audited against its own bias before it is trusted.

A creator-operations platform: Chat-first coordination between a creator and a production agency, with one hard approval gate no message skips.

A forensic personal-finance ledger: Ingests statements into a deduplicated, ownership-verified ledger, and never assumes a purchase is yours.

A research second brain: A topic in, a grounded report and a chat interface out, filed as plain markdown in a personal vault.

A face-first event gallery: A folder of event media and a folder of reference headshots in, a browsable face-organised gallery out.
