Sumble
Turn Long Audio into Instant Highlights
Hey Indie Hackers! ๐
I'm excited to soft-launch a project Iโve been working on โ Sumble ๐
๐ฏ What it does:
Sumble is a simple tool that lets you upload an audio or transcript file, and it uses AI to automatically generate:
- The most important highlights
- Timestamped summaries (in YouTube chapters format)
- Key quotes and moments
Perfect for content creators, podcasters, marketers, or anyone working with long recordings.

๐ก Why I built this:
I often find myself spending too much time scrubbing through interviews, podcasts, or webinar replays just to find the key moments. I figured there had to be a faster way โ and thatโs how Sumble started.
Itโs still early days, so Iโd really appreciate:
- Any feedback on the idea, copy, or UI
- Suggestions for features or use cases I might be missing
- Whether youโd use something like this yourself
Bonus: If you upload a file and try it out, let me know how it went! Iโm happy to return the favor and check out your project too.
Thanks, and looking forward to hearing your thoughts! ๐

Hi! I'm sure this is a great tool but I wasn't able to use it with the files I have stored. They were too large. How many minutes of audio usually fit? Generating YouTube chapters just from audio would only be useful for certain users (and very useful for them!) but putting audio on Youtube isn't something everyone does. Unless they have detached audio from a video and will reattach it after. I'm wondering what GPT it is using.
It would be cool if your tool could accept video input and just use the audio from it. I have a podcast repurposing service I offer and always scoping out what's on the market. I primarily work with video.
Keep up the great work!
