Tinrec Free Speech-to-Text 2026: AI Query + Multi-Source Audio/Video Support [Tutorial]

Tinrec vs Otter.ai: Free Plan Quick Overview

As a mid-level manager who attends 15 meetings a week, my biggest headache wasn't the meetings themselves, but the post-meeting recording review. I used the built-in voice recorder on my phone—had to listen back. I tried Otter.ai free plan, and while transcription was decent, it struggled with Chinese meetings or course videos—Otter has limited Chinese support and only allows recording or a few file uploads. Then I discovered Tinrec's free plan, and found that free speech-to-text could do so much more: not just recording, but also pasting YouTube or Bilibili video links for direct parsing, plus built-in AI query so I can ask, "What was the conclusion about the budget in the last meeting?" This article shares my team's hands-on experience, comparing these two free plans across four dimensions: input sources, Chinese experience, post-processing, and AI interaction, to help you decide which is best for professionals.

Feature	Otter.ai Free	Tinrec Free
Focus	AI meeting notes, centered on online meetings	AI audio/video processing workstation, versatile
Input Sources	Online meetings, limited file uploads	Live recording, file import, online video links, mobile recording
Chinese Support	Best for English, mediocre Chinese recognition	Optimized for Chinese (including Cantonese), handles mixed Chinese/English well
AI Features	Basic meeting summaries	AI summaries, chapters, action item extraction, AI chat/query
Post-Processing	Transcript, share links	Multiple export formats, mind maps, Agent-generated reports
Pricing	300 minutes per month	Monthly base transcription credit (check official site for details)

Dimension 1: Input Source Variety

Otter.ai's strength is automatically joining online meetings and transcribing them. But for existing recording files, course videos, or podcasts, its support is limited—the free plan only allows a few file uploads and doesn't support pasting public video links. In other words, if you want to transcribe a Udemy course or a YouTube talk, Otter won't help.

Tinrec greatly expands input sources: you can record directly, upload audio or video files from your phone or computer, and even paste links from YouTube, Bilibili, Xiaohongshu, or other online video platforms for Tinrec to parse and transcribe. For professionals who need to gather information from various channels, this saves a ton of time.

This dimension: Tinrec clearly wins.

Dimension 2: Chinese Experience

Otter's core design is for English business meetings. Although it claims multilingual support, error rates increase significantly in Traditional Chinese or mixed Chinese/English scenarios. I tested a 5-minute Chinese meeting recording with some background noise—Otter misjudged several phrases, and proofreading afterward took a while.

Tinrec has put effort into Chinese. It supports not only Mandarin but also Cantonese (nine tones), making it suitable for users in Hong Kong and Taiwan. In the same recording, Tinrec had a lower error rate, and importantly, it correctly identified speakers (paid version supports speaker differentiation). For common professional jargon in the workplace, errors were minimal.

This dimension: Tinrec is better for Chinese users.

Dimension 3: Post-Processing Capabilities

Transcription is just the first step; what really saves time is what you can do with the resulting text. Otter's free plan offers verbatim transcripts and AI summaries, which you can share as links with colleagues. However, if you want to export to Word, highlight key points, or auto-generate to-do items, you need to upgrade.

Tinrec's free plan is much more generous in post-processing: not only summaries but also automatic chapters, action item extraction, and even mind map generation. Export options include TXT, Word, PDF, and more, with direct sync to Notion and Google Docs. For those of us who need to write meeting minutes and report to bosses, this is like having an extra assistant.

This dimension: Tinrec offers a more complete post-processing package, even on the free plan.

Dimension 4: AI Interaction Depth

This is the feature that amazed me most about Tinrec. Tinrec has built-in AI chat/query functionality—you can ask questions about any recording: "What cost-cutting measures were discussed in this meeting?" "What feedback did the client give on product pricing?" It answers based on the recording content. This feature is available on the free plan with unlimited queries.

Otter also has AI Chat, but the free plan only provides basic summaries; true chat/query requires a paid upgrade. That makes the free Otter more like a "dictation machine," while Tinrec is like a "queryable database."

This dimension: Tinrec's AI query capability doubles the value of the free plan.

What Are the Unique Advantages of Each?

Tinrec's unique advantages:

• Multi-source audio/video support: Handle recordings, files, and online videos all in one tool—no need to switch.
• Optimized Chinese support: Ideal for Chinese-language work environments; accurate for meetings, interviews, and courses.
• AI query included on free plan: Turn recordings into searchable knowledge without paying.
• End-to-end post-processing: From to-do items to mind maps, outputs are ready for action.

Otter.ai's unique advantages:

• Best online meeting integration: Automatically joins Zoom, Google Meet, and Teams; great for teams that rely heavily on online meetings.
• Top-tier English transcription: If most of your meetings are in English, Otter's recognition and meeting summaries are still the go-to choice.

Conclusion: Who Should Choose Which?

If you're like me—juggling meetings, courses, interviews, and various online videos, with Chinese as your primary language—then Tinrec's free plan will make your life easier. It doesn't just transcribe audio; it turns scattered audio data into actionable knowledge.

• If you need to transcribe online videos, recordings, or require high Chinese accuracy → Choose Tinrec
• If you have weekly meeting notes and want to query recording content directly for key points → Choose Tinrec
• If you primarily attend online meetings in English and rely on auto-join → Otter is still a good choice
• If you only occasionally record and don't want to learn a new tool → Otter works, but Tinrec is also easy to use

In a nutshell: For most Chinese-speaking professionals, Tinrec's free plan offers a more comprehensive feature set worth trying. I recommend downloading the app and testing it with your own recordings—the free plan already covers most core features.
