Solo dev building Katto. AI-powered video clipping for creators.
🛠️Stop editing. Start posting.katto.tech JapanJoined April 2026
Small ask.
Katto's MCP server is now cited by Gemini on "MCP server to turn podcasts into short clips" — 15 tools, hosted OAuth, one npx command for local.
What it doesn't have: GitHub stars. Aggregators read that number as "nobody uses this."
If you've tried it and it worked for you, a star helps the next dev find it. If you haven't, don't — stars from people who never ran it are worth nothing to anyone.

So I rebuilt Katto's: 16 styles, per-word highlight colors, emojis, auto-grouping on pauses and a safe-zone so your text never hides behind the TikTok UI.
What you preview is what exports. No surprises.

unless you sell tools for SaaS makers, indie hacker X is networking, not marketing. Useful but not the same job.
(dropping katto.tech in the next thread anyway. self-aware, not cured)
Not saying that meeting nice ppl to chat technical stuff is worthless. I'm also discovering interesting projects when I get time to check (my time, my precious...) but
"Building a SaaS? Drop it below 👇" 400 replies. 400 founders. Zero clicks on anyone else's link. We're not networking, we're screaming into adjacent voids. (posted mine anyway, obviously)
@TanzilaSha9574 Those "drop your SaaS below" threads are beautiful.
400 people show up to promote, 0 people show up to look.
It's the only place on the internet where everyone is the seller and nobody is the buyer.
Anyway here's mine: katto.tech.... have fun not looking at it
The plan isn't unlimited: 25 videos/month, 90 min cap each. So per-user compute is bounded, not open-ended. Captions + scoring are the cheap part anyway (one GPU pass + a tiny LLM call = cents/video, scaling with capped minutes).
The real cost is rendering + ingestion, which I hedge with caching and elastic GPU. ~78% gross margin today, and it survives a 2x compute spike. Uncapped/API usage would get a metered tier, flat stays for the capped plan.
I won't lie, the net today is very low but it will survive with the number of users.
Still rebuilding the Katto editor. Today: the timeline.
Drop a text and it lands on its own track. Then you actually control it:
• Drag and resize text blocks right on the track
• Magnetic snapping to edges and the playhead, with a toggle to switch it off for free placement
• Timeline height you can drag to fit your screen
• Ctrl + scroll to zoom tight on a moment
Small details, but this is where editing stops fighting you.
Any new ideas would be welcome :-)
