These threads are great for impressions but weak for real traffic — everyone drops, few click. Still, here's mine: turns any YouTube lecture into study notes in 60s. Anyone actually convert from these?

Hiya! So I've been playing around with having Claude make videos for a bit now even had some success posting the results to TikTok (and setup a whole pipeline so Claude can generate and post autonomously). With the release of Nano Banana 2 Lite, I was curious show fast I could make the generation, so last night I gave it a whirl and got down to around 30s for short-form video. It uses GLM-5.2 fast via Fireworks to generate the scripts and image prompts and, like I said, Nano Banana 2 Lite for the images, gpt-4o-mini-tts for the narration, and ffmpeg to string it all together and add the Ken Burns zoom effect (which still has a shake I haven't been able to get rid of). The video compilation proved to be the blocker once the rest was in place, but I was able to speed that up by putting it on a 64 vCPU EC2. The cost might be the most interesting aspect as the short form videos tend to be about 25 cents. Almost 90% of that is the images, which are 3.336 cents a piece. Of course, running

Search YouTube channel transcripts to research content and build fair-use clips.

Built an entire YouTube research platform with @AnthropicAI Claude Code. a YouTube research tool that treats entire channels as a searchable transcript database rather than individual videos. Any YouTube channel. Every word. Fully searchable. Track how topics trend, peak, and evolve across hundreds of videos. Researching what someone said on YouTube means watching hours of footage and hoping you find it. ChannelScout extracts full transcripts from any channel, makes every word instantly searchable, and tracks how topics trend over time, without watching a single video manually. Paste a YouTube channel or playlist URL and it transcribes and indexes every transcript. Follow multiple channels and they all land in one private library. New videos on followed channels are auto-transcribed and added to your library the day they publish. Beyond YouTube it accepts any yt-dlp-supported URL including Vimeo, TED, and SoundCloud, and you can upload local files directly

I built a slide deck video builder Most AI generated visual can look like slop. I built a slide deck video builder for training content. It generates beautiful slide decks from 18 templates, adds voice over, allows post editing, and finally export to mp4. Check it out at https://inkbolt.ai and let me know what you think! I have to give a shout out to this repo for inspiring how to do design properly with AI. https://github.com/zarazhangrui/frontend-slides submitted b

Built an AI SaaS that turns your notes/articles/PDFs into study flashcards — looking for harsh feedback (and bugs) Hey folks, Solo/small side project here: Deckly ( deckly.one ) — an AI-powered flashcard generator for spaced-repetition learning (Anki-compatible export). You give it text, a PDF, or an article link, it generates a deck of flashcards (Q&A, Cloze, or multiple choice), optionally with TTS audio and images per card, and you can study it right in the browser or export to `.apkg`.
