GPT Nitro for Github PR2023 · github.com · ▲113A ChatGPT-based reviewer for your GitHub pull requests
I made a heatmap diff viewer for code reviewsOct 2025 · 0github.com · ▲2650github.com is a pull request viewer that color-codes every diff line/token by how much human attention it probably needs. Unlike PR-review bots, we try to flag not just by "is it a bug?" but by "is it worth a second look?" (examples: hard-coded secret, weird crypto mode, gnarly logic, ugly code). To try it, replace github.com with 0github.com in any pull-request URL. Under the hood, we split the PR into individual files, and for each file, we ask an LLM to annotate each line with a data structure that we parse into a colored heatmap. Examples:…

AI explanations for other people’s code2023 · whatdoesthiscodedo.com · ▲186Hi HN, As a developer, I much prefer to write code than read other people’s code. But most projects I work on involve other developers so it’s hard to avoid. Often I find it really hard to quickly parse other people’s code so I thought maybe ChatGPT could help. ChatGPT does a really nice job of giving clear explanations when you paste in code and ask it to explain it. But the interface is a bit of a pain to use if you’re using it many times a day. It’s also hard to share explanations with co-workers. So I built whatdoesthiscodedo.com. Just paste your code and get your ChatGPT explanation and…

I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
