How hands-off: Assists you, you do the final step
Setup: A bigger project · a few focused days

Watch out for

AssemblyAI webhooks may arrive out of order if multiple calls are processed simultaneously, so add a unique call ID field to correlate results correctly.
OpenAI responses can occasionally fail JSON validation due to trailing commas or markdown formatting, so implement a retry loop with regex cleanup logic.
Large audio files may exceed AssemblyAI's timeout limits for webhook delivery, so monitor file sizes and consider splitting long recordings into chunks beforehand.
Supabase insertions might fail if the AI returns null values for required fields, so add default value mappings in the workflow before the database step.
