Pricing Face-Off

Otter wins on pricing at every level. At $8.33/month on annual billing, it’s almost half the cost of Sembly’s $15 Professional tier. The free tier is also far more generous - 300 minutes versus 60. Even at Team level, Otter ($20/user) is cheaper than Sembly ($29/user).

Features Compared

Transcription

Otter was built for real-time transcription first. The live transcription is fast, accurate on clean audio, and the collaborative editing (multiple people annotating the transcript live) is the best in class.

Sembly transcribes too, but its differentiator isn’t transcription speed - it’s what happens after.

AI Capabilities

Sembly’s AI strengths:

• AI Artifacts: Generate documents from meetings - project plans, proposals, briefs
• Multi-meeting chat: Query across your entire meeting history
• Semblian 2.0: Advanced AI that produces structured outputs

Otter’s AI strengths:

• AI summaries: Basic meeting summaries with action items
• Otter AI Chat: Query your meeting content (limited to 20 queries/month on free)
• Slide capture: Pull slides from virtual meetings automatically

Sembly’s AI features are more powerful and differentiated. Otter’s AI feels more like an add-on than a core capability.

Language Support

This is a massive gap:

• Sembly: 48 languages
• Otter: English, Japanese, Spanish, French

If your team operates in languages beyond those four, Sembly is the only choice. For English-dominant teams, this matters less.

Integrations

Otter integrates with Zoom, Google Meet, Teams, Salesforce, HubSpot, and Dropbox. Sembly also integrates with Zoom, Google Meet, Teams, Webex, Slack, Notion, Salesforce, and Google Drive.

Both cover the major platforms. Sembly has a slight edge with Webex and Notion integrations.

Where Sembly Wins

• AI document generation: Unique capability that no competitor matches
• Language support: 48 languages versus 4 makes it viable for global teams
• Multi-meeting intelligence: Query patterns across months of meetings
• Security: SOC 2 Type II, GDPR standard; Enterprise has HIPAA
• Better rating: 7.5 versus 7.0 reflects deeper feature set

Where Otter Wins

• Better free tier: 300 minutes versus 60 is a huge gap
• Lower entry price: $8.33/mo versus $15/mo
• Real-time collaboration: Multiple people can annotate a live transcript
• Brand recognition: Established, trusted, proven at scale
• Mobile recording: Better for in-person meetings recorded on phone

The Verdict

For most teams, Sembly AI delivers more value. The AI document generation is practically useful, the language support makes it viable for global teams, and the multi-meeting intelligence is powerful for tracking patterns.

Choose Sembly if:

• You need to generate documents from meetings
