Show HN: I built Magiclip – an all-in-one AI studio
Hi HN
I’ve been working on a tool I personally needed as someone who edits a lot of video content.
The problem is simple:
Modern video editing requires 8+ different tools, all slow, all noisy, all repetitive.
Subtitles here. Audio cleanup there. Silence removal elsewhere. Upscaling in another tool. AI voice in a different one. A clip extractor somewhere else…
So I built Magiclip.io — a single interface that automates the most boring parts of editing.
What it does today
Auto-subtitles (fast & accurate)
Silence removal
AI voice-over
Audio enhancement
Image upscaling
Clip extraction from long videos
Thumbnail generation
Quick TikTok/Reels format conversion
And more coming
The idea isn’t to replace full editors. It’s to remove the friction of things we repeat 100 times.
Upload → Magic → Download. No timeline, no project files, no complexity.
Why I built it
I edit content frequently, and the workflow felt unnecessarily painful. Magiclip is my attempt to reduce editing from hours to seconds by batching the most common tasks behind simple endpoints.
What I’d love feedback on
What other tasks should be automated?
Anything in the UX that feels off or slow?
Any feature you’d want exposed through an API?

Happy to answer anything about the architecture, the pipelines, or the reasoning behind the features.
