Web apps and developer tools, built in Haskell in the UK.

• FileChanger

  Converts Typst, Org-mode, AsciiDoc, DocBook, Jira markup, LaTeX and Markdown in any direction, plus documents, images, audio and video, through one API and an MCP server.

• Model Waygate

  An OpenAI- and Anthropic-compatible gateway on your own provider keys, routing each request through the fallbacks, retries and circuit breakers you draw in its editor.

• Word Burst

  A calm, untimed spelling game: type in the words you want to learn, then drag the scattered letters back into place to spell each one.

• Roll Dice

  Rolls dice for tabletop roleplaying games, with quick buttons for D&D, Cypher, Call of Cthulhu and Daggerheart and a box for any dice expression.

• Request Proxy

  An HTTP proxy that puts retries with backoff, circuit breaking and rate limiting in front of the APIs you call.

• Comment Sentiments

  Sentiment analysis for comment sections, so you can read the reaction to a post without wading through every comment.
