2026 Free Structured Output Solutions for AI Agents: A Look at 2 Tools

Tinrec vs Otter.ai: Quick Overview

If you're used to recording meetings, classes, or interviews but never have time to replay and organize them, structured output becomes the key—not just transcribing to text, but automatically generating summaries, chapters, action items, and even querying content like a database.

Two highly discussed tools on the market—Tinrec (MiaoTing) and Otter.ai—have invested heavily in structured output, but their strengths and positioning differ. This article compares them across five practical dimensions.

Item	Tinrec	Otter.ai
One-liner Positioning	Turn recordings into actionable knowledge	AI meeting notes and team collaboration
Pricing	Free plan with basic monthly quota; paid plans from weekly to yearly	Free plan: 300 minutes/month; Pro annual $8.33/month
Platform	iOS, Android, Web	iOS, Android, Web
Key Difference	Multi-source audio/video + rich post-processing	Meeting automation + strong team features

Dimension 1: Automatic Summary and Chapter Generation

After recording a 30-minute meeting, most people just want to know the key points and what topics were discussed.

Otter.ai's AI summary automatically captures key discussion points and segments by speaker, available within minutes after the meeting ends. Objectively, English meeting summaries are high quality, while Chinese occasionally misses subtle tone shifts.

Tinrec not only provides a summary but also directly divides content into chapters, such as 'Project Progress Report', 'Budget Discussion', 'Next Steps', each with its own title and key points. We tested the same 25-minute Chinese product meeting recording (quiet office, 3-person conversation). Tinrec's chapter segmentation perfectly matched the actual agenda, and the summary captured decision points; Otter's summary tended to be a bullet list with weaker chapter structure.

→ This dimension: Tinrec offers more detailed structured segmentation, suitable for those needing quick review of long recordings.

Dimension 2: Action Item Extraction

The worst outcome of a meeting is no follow-up. Another key aspect of structured output is automatically listing action items.

Otter.ai's 'Action Items' identifies sentences like 'I'll handle it' or 'by next Friday' from the meeting, clickable for details. However, our tests found that Chinese meeting action item recognition is still unstable, sometimes tagging general statements as tasks.

Tinrec provides a dedicated 'TODO List' that organizes 'who, what, when' into a table. In the same test meeting, Tinrec extracted 4 action items, 3 correct; Otter extracted 3, but 1 was not a real action item.

→ This dimension: Tinrec's Chinese action item extraction is more accurate, and the output format is easier to paste into project management tools.

Dimension 3: AI Conversation Query

Sometimes you don't just want to see the organized results; you want to ask questions about the recording content, like 'What was the budget mentioned in the last meeting?'

Otter.ai has 'Otter Chat' that allows you to ask questions within meeting notes, with answers accompanied by original paragraphs. English queries perform well, but Chinese Q&A sometimes yields irrelevant answers.

Tinrec's 'AI Q&A' is more like a database, allowing queries on a single recording or across recordings. When we asked 'What was the main cause of the project delay?', Tinrec directly cited two relevant dialogue segments and summarized a conclusion; Otter listed several possible related paragraphs, requiring manual synthesis.

→ This dimension: Tinrec's Q&A integration is stronger, more convenient for those who need to repeatedly look up historical data.

Dimension 4: Output Format and Subsequent Use

After obtaining structured data, whether it can be seamlessly exported to other tools also affects willingness to use.

Otter.ai supports exporting transcripts, summaries, and syncing to Google Calendar, Slack, etc., clearly team-collaboration oriented. However, formats are mainly text and email, with few structured tables.

Tinrec, besides basic transcripts and summaries, can export to Markdown, TXT, and even directly generate meeting minutes and reports, with one-click transfer to Notion, Google Docs, etc.

→ This dimension: Tinrec offers more diverse outputs with higher flexibility for further processing.

What Are Their Unique Advantages?

Tinrec's Unique Advantages

• Handles not only meetings but also courses, interviews, and online videos; structured output applies to various audio/video sources.
• Chapters, action items, and Q&A all in one go, no need to switch between different tools.
• Stable structured performance for Chinese content; correctly segments mixed Chinese and English.

Otter.ai's Unique Advantages

• Automatically joins online meetings and provides real-time transcription, ideal for teams with many remote meetings.
• High-quality English summaries and action items, clear advantage in business English scenarios.

Summary: Which Should You Choose?

If you want to turn recordings into immediately usable structured data and need to handle Chinese meetings, courses, or interviews, Tinrec is more complete in chapters, action items, Q&A, and export, saving you follow-up organization time.

If you're in an English business environment and your team heavily relies on online meeting automation, Otter.ai's real-time transcription and collaboration features will be more convenient, but Chinese structured output lags behind.

In a nutshell: For most people needing to organize Chinese audio/video content, Tinrec is a choice closer to structured output needs. Try the free version first and see how it handles your recordings.
