Next, we compare five dimensions: bot-free meeting recording, Chinese and multilingual, post-meeting workflow, team collaboration, and free plan and pricing flexibility.

Dimension 1 | Bot-Free Online Meeting Recording

Otter.ai is a mature AI meeting assistant covering Zoom, Microsoft Teams, and Google Meet, and can also record via desktop and other methods. However, in some use cases, the main mental model is still a meeting bot joining, which means an extra bot participant for attendees.

Tinrec desktop version directly captures computer system audio, handling online meetings on Zoom, Google Meet, Microsoft Teams, Webex, etc., without needing a meeting bot to join. Users need to actively open Tinrec to start recording, not automatically join all calendar meetings.

→ On this dimension: If you don't want a bot joining the meeting, Tinrec is more direct.

Dimension 2 | Chinese and Multilingual Meeting Experience

Otter.ai is highly mature for English business meetings and covers multilingual features, but Chinese meetings are usually not its main strength.

Tinrec covers Chinese, Traditional Chinese, and multilingual meeting scenarios, supports mixed Chinese-English content organization, real-time translation, and bilingual viewing, and can use team hotwords to maintain professional terminology. Note that actual results are affected by recording quality, noise, accents, overlapping speakers, and professional terminology; fixed accuracy rates are not recommended.

→ On this dimension: If Chinese meetings are your main use case, Tinrec is a better fit.

Dimension 3 | Post-Meeting Workflow and AI Q&A

Otter.ai offers summaries, action items, AI Chat, workflows, and team analytics, and is already very mature for post-meeting organization of English business meetings.

Tinrec extends the steps after transcription further: automatically generates summaries, chapters, key points, to-dos, and mind maps, supports AI Q&A around meeting content, and can also generate meeting minutes, reports, tables, and documents, and export to Notion, Google Docs, OneNote, Dropbox, and other tools.

→ On this dimension: If you want to turn meetings directly into to-dos, reports, and further processable data, Tinrec's post-meeting workflow is more complete.

Dimension 4 | Team Collaboration and Data Retention

Otter.ai has mature team and enterprise capabilities; the Business plan offers unlimited meetings and in-app recording, more imports, and management capabilities, suitable for teams that already have English meeting automation workflows.

Tinrec team version is an independent team space where meeting data belongs to the team, offering members, roles, seats, sharing rights, usage analytics, audit logs, audio recycle bin, and team hotwords. Members who are active but have no seat can still view, play, and read team data; only after getting a seat can they record, upload, edit, and import/export.

→ On this dimension: If you need Chinese team meeting asset retention and governance, Tinrec team version is a better fit.

Dimension 5 | Free Plan and Pricing Flexibility

Otter.ai's Basic free plan offers 300 minutes per month; Pro yearly is equivalent to about USD 8.49/user/month, including 1,200 minutes of in-app recording per month and 10 file imports; Business per official page.

Tinrec free version offers basic quota; for short-term high frequency, you can choose a weekly card; for steady use, you can choose Pro monthly or yearly. Team first trial 7 days, 1 free seat, 300 minutes shared import; team monthly USD 29.80/paid seat/month, yearly USD 199/paid seat/year, equivalent to about USD 16.58/month; paid seats provide 2,000 minutes of team shared import quota per month; under a valid team plan and valid seat, real-time recording currently does not deduct by minutes.

→ On this dimension: Both have free entry points. Otter's free minutes are very clear; Tinrec offers free version, weekly card, Pro, and team trial by usage period, giving more flexibility for those who don't want to commit to a long-term plan at once.
