Threadline PRO - The first AI video editor that listens to how you speak

Hey PH! I'm Jacinto, co-founder of Threadline.

I've spent the last decade making documentaries and branded video, and every project starts the same way: you record great footage, then spend 10x longer trying to turn it into something you can actually use.

Here's what bothered me most: every AI editing tool out there just reads a transcript. It treats your footage like a text document. But the best moments in video aren't about the words. They're about how someone says it. The pause before the honest answer. The shift in energy when someone gets excited.

So my co-founder Bradley (previously a founding engineer at Tavus, YC S21) and I built Threadline to actually listen. We use intonation analysis to detect tone, emphasis, and pacing in your footage, not just the words. That means Threadline can find the moments that matter, the ones a transcript-based tool would miss completely.

Upload your footage. Get a transcript in seconds. Pull your selects or let AI find them using intonation and delivery cues. Chat with AI to reshape your edit. Export a structured sequence into Premiere Pro, DaVinci Resolve, or Final Cut Pro.

We ran an alpha with professional editors and the results blew us away. One editor went from one assembly per day to eight. 78% exported their results and used them on real client work.

Threadline is free to start, no credit card required. Sign up in the next 72 hours and get 30% off Pro for your first 3 months.

What's the moment in your footage you always know is gold but can never find fast enough?

Solid product, even through the early alpha builds. As a user I'm occasionally making work that's the perfect fit for Threadline but more often then not I'm throwing edge-cases at it and it STILL drastically speeds up my workflow.

Hugely impressive.

This is insanely clean, well done on the launch!
