Multilingual teams and document-heavy workflows
Teams needing live captions and accessible transcription
Sembly AI and Otter.ai are both AI meeting assistants, but they solve different problems. Otter.ai is built around live transcription - showing text in real time as people speak during the meeting. Sembly is built around what happens after the meeting - generating structured documents through AI Artifacts.
The most important practical difference: Otter.ai supports 3 languages (English, Spanish, French). Sembly supports 50+ with automatic detection. For international teams, this is often the deciding factor before anything else is considered.
Free Plans
Otter.ai gives 300 minutes per month on the free tier with a 30-minute per-meeting cap. Sembly gives 5 meetings per month with no time cap per meeting. For short meetings, Otter's cap is more generous. For longer meetings (60+ minutes), Sembly's 5-meeting limit is more practical. Neither free tier is generous enough for daily professional use.
What Each Does That the Other Cannot
Otter.ai shows live transcription to all meeting participants during the call. No other tool in this category does this as reliably. If accessibility, live captions, or real-time note sharing during meetings are requirements, Otter.ai is the only option here.
Sembly's AI Artifacts generates structured follow-up documents after meetings. Otter.ai has no equivalent - it produces summaries, but not proposals, project briefs, or executive emails from meeting content. If document generation is the workflow, Sembly is the only option.
