PasteClean

Hi HN, I built PasteClean, a small, free, client-side tool to fix a problem I kept running into when pasting ChatGPT output into Outlook and other email clients. When you paste AI-generated text into Outlook, bullet points and paragraphs often end up with extra spacing. This happens because of how lists and paragraphs are represented in HTML and how Outlook renders them. PasteClean lets you: - Paste content from ChatGPT/Claude/Gemini/Perplexity (or anywhere) - Optionally edit it - Clean up spacing, lists, and formatting - Copy the result as cleaned HTML Everything runs…

    I caught myself copy-pasting into ChatGPT like 50 times a day. Too lazy for that, so I built a shortcut. Select text anywhere on Mac, press a hotkey — text gets rewritten / translated / summarized / whatever, right where you are. No tabs, no copy-paste dance. Native Swift app, hooks into macOS accessibility APIs. Bring your own API key and calls go straight to OpenAI / Anthropic. Or just use the free tier — 20 requests/day, no signup. https://aihotkeys.tech Curious for the feedback

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
