Best for

AssemblyAI

Pick AssemblyAI when you need accurate streaming/batch ASR plus diarisation + summarisation without engineering it yourself.

Vibe

Pick Vibe if you want a free, private, GPU-accelerated Whisper desktop app with diarization and a scriptable local API.

Not for

AssemblyAI

Skip it at extreme volume — Whisper self-hosted is cheaper if engineering capacity is available.

Vibe

Skip it if you need a cloud SaaS with team workspaces, SLAs, or mobile capture today.
