Chrome extension that drafts your Reddit comments in your own voice, not ChatGPT's.
u/B3N0U · Reddit
I got tired of Reddit replies that sound like ChatGPT, so I built a tool that writes in my own tone of voice I lurk way more than I post, mostly because writing a good reply takes time and half the AI-assisted comments you see now get sniffed out and downvoted instantly. You know the ones: "Great question! In today's fast-paced landscape..." Nobody talks like that. So I built a small Chrome extension for myself. It reads the whole thread, then drafts a comment right inside Reddit's reply bo

Re-explain any learning material in your own words with adaptive questions that reveal what you actually understand.
@indrajit_tweets · X
Most AI learning tools explain concepts for you through summaries, notes, quizzes, and flashcards. But recognising an answer is not the same as understanding it. That’s why I built ReExplain ( for the @OpenAI Build Week Hackathon. ReExplain flips the roles - the AI becomes the curious learner, and you become the teacher. You explain the material in your own words, while the AI listens, identifies gaps, and asks follow-up questions that challenge you to think deeper. Powered by GPT-5.6 Luna and built with Codex, ReExplain is now live on Product Hunt! If the idea resonates with you, I’d really appreciate your upvote and support 😄 🔗 Product Hunt Launch Link: Watch the demo, try it, and share your feedback! #ProductHunt #OpenAI #BuildWeek #AI #EdTech #Hackathon

Generate Gmail replies in your personal writing voice using AI trained on your emails.
u/Sea_Visual9618 · Reddit
I fed an AI 12,000 of my sent emails to clone my writing voice. My cofounder couldn't tell which replies were mine. Bit of background: I've spent ~2 hours a day in Gmail for the last two years, and almost none of it was thinking. It was re-typing the same six replies. So the side project started as a dumb question: if I gave a model every email I'd ever sent, could it write like me? Not "professional email tone" — me. The lowercase, the "sounds good, will do by fri," the fact

Crawls your site and scores how AI-written your copy sounds, with evidence and rewrites.
u/NotGeorge1 · Reddit
I built a tool that scores how Ai-written your site sounds. My own homepage got 6 out of 100. I've spent the last month building SiteTell . It crawls a site and scores the copy against a curated rule set of the patterns that make writing read as Ai-generated. Generic vocabulary, structural tells, the openers that show up on every generated landing page. When it was working well enough to test, I decided to run it on my own site. It scored 6 out of 100. I'll be honest, in the first instan
