what if you could drop in a youtube link...

get a transcription...

then have a generative AI model answer your questions BASED on the transcript via a web interface?

@AssemblyAI is building that right now

I'm facing 2 issues using @OpenAi's Whisper Speech to Text with @Bubble.

1. Whisper's max file size limit of 25 mb.
2. Bubble API timing out for larger videos.

I've now been using @AssemblyAI Speech to Text API for a day and I'm really impressed.

Here's why 🧡

This is a game changer, I've just created this summary blog on a recent podcast from my YouTube channel using @AssemblyAI's new LLM model LeMUR.

The performance of @AssemblyAI's new Conformer-1 ASR model looks really promising, can't wait to give it a try!

Should I transcribe all videos on my YT channel? πŸ€”

I transcribed @dwarkesh_sp's first episode with @tylercowen four different ways.

1. Deepgram
2. AssemblyAI
3. Gladia
4. Local inference (using Dwarkesh's Speechbrain Pyannote model)

The winner?

Thanks Patrick. πŸ™

The API integration has been super straightforward and we've gotten a lot of support with credits and reduced pricing for startups.

Can recommend @AssemblyAI to anyone looking to integrate transcription into their product. πŸŽ‰

If you want to use an external dependency, I highly recommend @AssemblyAI

1) Discord is where our dev support volume is @Superfluid_HQ

2) A teammate recommended @supabase so went w that. I've heard good things about @pinecone tho

I'll check out what you built! I also recommend @AssemblyAI for audio transcriptions. Better performance & better DevX than Whisper

I just launched http://ToastyAI.com yesterday to address a bit of this problem. I’d recommend using alternative transcription services like AssemblyAI if you’re looking to send URLs - also they have a higher transcription accuracy than Whisper + timestamps
