A collection of miscellaneous HTML+JavaScript single-page tools hosted at tools.simonwillison.net, almost entirely generated with LLMs as an experiment in prompt-driven development. The repo contains the source for dozens of small utilities like OCR, markdown converters, token counters, and image tools.
Use cases
- run quick OCR on an image in the browser
- convert rich text to markdown
- count Claude tokens for a prompt
- extract tables from HTML
- resize images and check quality
- find small single-purpose browser utilities
When to choose
- you need a small client-side utility with no install
- you want examples of LLM-generated JavaScript tools
- you want to study prompt-driven development with commit transcripts
When to avoid
- you need a maintained production library or API
- you need tools with guaranteed support or tests
- you need server-side or native application functionality
