The trade-offs
Strengths and Limitations
AssemblyAI
Strengths
- Pay-as-you-go with no subscription and $50 in free credits to start
- 99 languages for pre-recorded transcription on Universal-2
- Compliance certifications and an EU region at no price premium
- Official MCP server exposes transcription and transcript search to AI agents
Limitations
- A developer API, not a ready-made studio or editor
- No voice cloning or voice creation
- Speech Understanding add-ons are billed on top of the base rate, so cost stacks per request
- Streaming is billed for as long as the connection stays open, not for the audio sent, and multichannel files are billed per channel
- Universal-3.5 Pro covers 18 languages against 99 on the older Universal-2
Granola
Strengths
- No bot joins the call, so nothing appears in the attendee list
- Expands shorthand typed during the meeting instead of replacing note-taking
- AI chat runs across the whole meeting history, not a single transcript
- Opt-out of model training on every plan, including the free one
- MCP server and API on Business, so meeting context reaches other AI tools
Limitations
- Capture depends on a machine being in the meeting, since it records local computer audio
- The free plan limits how far meeting history reaches back
- Integrations, API and MCP start on the Business plan
