BrainTripping

BrainTripping is a whimsical Markov-chain language game founded by Matthew Huebert in the Y Combinator Summer 2012 batch. It lets players step inside the vocabularies of famous historical and modern figures and compose their own sentences, constrained to that person's word patterns. The company is no longer active as a startup; today the BrainTripping GitHub organization publishes open-source ClojureScript tooling such as cljs-live, magic-tree, and the Lark editor. The public surface is a single-page ClojureScript web app at braintripping.com and it exposes no public REST API, SDK, or developer platform.

BrainTripping is profiled on the APIs.io network. Tagged areas include Company, Language, Games, Natural Language Processing, and ClojureScript.

x-enrichment-note: Enriched 2026-07-18. BrainTripping is a defunct YC S2012 Markov-chain language game and an open-source
  ClojureScript GitHub organization, not an API provider. No OpenAPI, AsyncAPI, SDK, MCP, well-known, or developer surface
  exists (the site is a SPA that returns its app shell for every path, including /.well-known/security.txt, /openapi.json,
  and /llms.txt). Enrichment was therefore limited to honest identity hygiene plus a live domain-security probe; no API artifacts
  were fabricated.
