Dumme
AI that automatically generates short-form highlight clips from long-form YouTube videos and podcasts for TikTok, Reels, and Shorts.
Dumme is an AI video repurposing platform that analyzes long-form YouTube videos and podcast episodes and automatically selects and exports the most engaging moments as short-form vertical clips optimized for TikTok, Instagram Reels, and YouTube Shorts. Unlike clip selection tools that require manual marking of in and out points, Dumme uses AI to identify high-engagement segments based on transcript content, speaker energy, and topic density - then crops, reformats, and optionally captions the clips for vertical viewing. Backed by Y Combinator, Dumme targets YouTubers and podcasters who know they should be distributing on short-form platforms but lack the time to manually clip episodes. The platform connects via YouTube link or file upload and returns a set of ready-to-post clips with social captions. Free and paid plans are available with paid tiers starting around $19 per month.
Key Features
- AI clip selection - identifies the highest-engagement moments from long-form video without manual marking
- Vertical reformatting - auto-reframes horizontal 16:9 footage to 9:16 for Reels, TikTok, and Shorts
- Auto-captioning with word-level highlighting synced to speaker audio
- Social copy generation - produces caption text, hashtags, and hook suggestions for each clip
- YouTube link input - no file download or upload required for YouTube-hosted content
- Batch processing for podcast networks and multi-channel creators managing high episode volumes
Use Cases
- YouTubers with long tutorial or interview content who want a short-form presence without a dedicated editor
- Podcast hosts distributing audiogram and video clips to grow on Instagram and TikTok
- Brands repurposing webinar recordings and keynote presentations into social media content series
- Agencies managing social content calendars for clients with existing video libraries to draw from
Pros
- Fully autonomous clip selection removes the most time-consuming step in the repurposing workflow
- YouTube link input eliminates the download-upload cycle that slows other repurposing tools
- YC backing and focused product scope reflects a team committed to this specific creator workflow
Cons
- AI clip selection favors speaker intensity and topic density and may miss nuanced or slow-burn engaging moments
- Output captions may need styling and accuracy corrections for creator channels with distinct brand aesthetics
- Clip count per video is limited on lower pricing tiers, which constrains use for very long-form content
