They picked the wrong camping spot. 🍄

What does space actually smell like? An astronaut answers, at NASA's Crew-12 post-flight news conference. Katto's AI picked this moment out of the full briefing. Source: NASA (public domain) https://t.co/OiNtXCiEfk #NASA #space

A sheep, a salesman, and a deal that's too good to be true. Katto pulled this moment out of Blender Studio's 12-minute short Cosmos Laundromat. Source: Blender Studio, "Cosmos Laundromat" (CC BY) https://t.co/OiNtXCiEfk #Blender #animation

Sprite Fright is a 10-minute horror comedy. Katto's AI picked these 28 seconds: a forest ranger, a botany nerd, and the worst pun in the woods. Source: Blender Studio, "Sprite Fright" (CC BY) https://t.co/OiNtXCiEfk #Blender #animation

Katto's virality score is Hook 30 + Flow 30 + Value 25 + Trend 15. I published the exact rules, and why the top-scored clip isn't always the one you should post. https://t.co/CB1qPyMTzM

13 AI video tools now have an MCP server, so Claude, ChatGPT or Cursor can make clips for you. I compared all 13: which plan you need, what the agent can do, and the one-line install for each. https://t.co/HWeI3bICmw

Katto can dub a clip into 105 languages: 19 stable, 86 in beta, including 15 languages spoken in India besides Hindi. Caption translation covers 19. The full list, and how dubbing differs from translated captions: https://t.co/VV0uVcAq5x

Reap Creator: $9.99/mo yearly for 10 hours of video. Katto Creator: €11.90/mo yearly for 25 videos up to 90 min each. I compared Reap, Katto, OpusClip, Klap and Vizard, including when Reap is the better pick. https://t.co/SZFql30BrD

Podcast clips are tricky: two people on screen, long episodes, audio-only shows. We compared 8 AI clip makers on exactly that, with prices checked today and the honest cases where Katto isn't the right pick. https://t.co/7v2r51yLq2

@ARJUNNANGAl007 Yes ?

[Anthony ✦ Katto.tech @Katto_Tech]

Katto now dubs clips into 105 languages.
The 86 new ones each passed a round-trip test: translate, speak, then a separate audio model has to name the language and transcribe it back. Wolof, Dzongkha and Sundanese failed. So they're not in. https://t.co/1dsha4b2fs

78 videos clipped on Katto yesterday, by 61 people. My best day so far was 29.

Happy… and a bit frustrated: almost nobody tells me what they think. Analytics show what people click, not why they leave.

Tried it? Good or bad, reply here. I read everything and fix it as soon as I’ve finished sleeping ^^

Turning 16:9 into 9:16 throws away two thirds of the frame.

A centre crop cuts people off. Letterbox makes them tiny.

Katto picks the framing shot by shot: close-up, wide, split screen, panel grid. On a panel of four, everyone stays in.

Fixed now. If you tried clipping videos with Katto from Claude, ChatGPT or Cursor in the last few weeks and gave up, it works, no need to reconnect.

Setup for every assistant: https://t.co/25tk8nbkKe

[Anthony ✦ Katto.tech @Katto_Tech]

Our AI connector was broken for 19 days and every check said it was fine.

Claude listed Katto as “connected”. The tool list loaded. But every real call returned 404: a security rule we’d added was blocking the connector’s own requests.

Lesson: monitor the call, not the handshake.

@verbove Katto is my app not a startup ^^

Katto now runs inside ChatGPT.

Add https://t.co/9AaXp355Dg as a custom MCP server, sign in, and ask it to clip a long video: you get ranked 9:16 clips back in the chat.

Listing in the ChatGPT directory is under review.
