Hi, I'm Tom

Building verifiable, truth-seeking AI agents

I'm building AI agents that verify their reasoning on complex, controversial questions — surfacing counter-arguments, stress-testing logic, and turning confusion into clarity. This will 100x intellectual work and make real-time fact-checking possible.

I'm based in London, UK.

What I'm Building

Open Debate

Open Source

An AI debate arena where language models argue opposing viewpoints, get judged, and learn from their losses. Run debates that would never happen IRL — people who refuse to engage, won't share a stage, or are ideologically incompatible.

  • • Recursive self-improvement — debaters reflect and evolve between rounds
  • • Minimal "vanilla" prompts to surface raw model behavior
  • • Human-in-the-loop coaching mode
  • • CLI-first, designed for experimentation

Argument Analyzer

Open Source

Real-time argument analysis as you write. Two AI agents work in the background: Steelman surfaces the strongest version of your argument, Counter shows the objections your opponents will raise.

  • • Feedback appears as you write, no button to click
  • • Click feedback to jump to the relevant passage
  • • Chat assistant for improving specific sections
