Markup

What it does

Markup is a free & open-source annotation tool for transforming text into structured datasets that you can use to train ML models. Markup uses GPT-4 to learn how you annotate, so it can make smart suggestions and significantly speed up the process.

  I made a tool to clean and convert any webpage to Markdown2024 · markdowndown.vercel.app · ▲441

  My partner usually writes substack posts which I then mirror to our website’s blog section. To automate this, I made a simple tool to scrape the post and clean it so that I can drop it to our blog easily. This might be useful to others as well. Oh and ofcourse you can instruct GPT to make any final edits :D

  Structured output from LLMs without reprompting2023 · automorphic.ai · ▲174

  Built a tool for transforming unstructured data into structured outputs using language models (with 100% adherence). If you're facing problems getting GPT to adhere to a schema (JSON, XML, etc.) or regex, need to bulk process some unstructured data, or generate synthetic data, check it out. We run our own tuned model (you can self-host if you want), so, we're able to have incredibly fine grained control over text generation.
