Turn recordings into transcripts and summaries in minutes
Upload audio or video for multilingual transcription, AI notes, and action items
Having back-to-back meetings all day and then working overtime to transcribe recordings for meeting notes—that's the daily routine for many office workers in Central. You want an app to help, but the price tags make you hesitate. The truth is, many speech-to-text tools now offer free versions that are sufficient for basic use. Today we picked two popular free options on iOS: Tinrec (Miao Ting Recording) and Otter.ai, to help you compare which one suits Hong Kong users better.
Tinrec vs Otter.ai: Quick Overview
Tinrec is an AI-powered recording and audio/video organization tool, strong at handling multi-source audio/video data including meetings, classes, interviews, and even YouTube videos. After transcription, it can generate AI summaries, to-do lists, and exports. Otter.ai is a classic AI meeting bot that automatically joins Zoom and Google Meet, focusing on English transcription and team collaboration. Both have iOS apps and free versions, but their actual experiences differ quite a bit. Let's break it down dimension by dimension.
| Quick Comparison | Tinrec | Otter.ai |
|---|---|---|
| Free transcription quota | Monthly base quota (enough for daily short meetings) | 300 minutes per month |
| Cantonese recognition | Optimized for Cantonese tones, performs well with mixed Chinese-English | Primarily English, Cantonese accuracy is average |
| Input sources | Live recording, audio/video files, web links (YouTube, TikTok, etc.) | Meeting platforms (Zoom, Meet, Teams), limited file imports |
| AI post-processing | Summary, chapters, to-do list, AI Q&A, mind map, multi-format export | Summary, action items, AI Chat |
| Cross-platform | iOS, Android, Web | iOS, Android, Web |
Dimension 1: Free Transcription Quota and Features
Otter's free version generously offers 300 minutes of transcription, enough for general meetings. But features are basically transcription plus simple summaries; you'll need to upgrade to Pro for AI Q&A or more advanced organization.
Tinrec's free version also has a basic transcription quota, but with fewer feature restrictions—even the free plan includes live recording to text, importing audio files, web video parsing, AI summaries, chapters, and to-do extraction. You can also ask questions about the recording content through AI Q&A, something Otter's free version can't do.
→ This dimension: Tinrec's free version offers more complete features, better value.

Dimension 2: Cantonese Recognition
Work conversations are often mixed with English and Cantonese, with several colleagues chatting together and background noise. Accuracy of transcription tools is crucial. We tested with the same 5-minute Cantonese meeting recording (iPhone 14, office environment, 26°C). Otter, being English-focused, often misheard Cantonese words like "係" (hai) becoming "系" (xi) or "唔該" (m goi) becoming "母雞" (mou gai). Error rates were notably high during Chinese-English code-switching.
Tinrec, on the other hand, is clearly optimized for Cantonese tones. The same recording had far fewer errors, with high recognition for local terms like "佢哋" (they), "聽日" (tomorrow), and "執手尾" (clean up). Of course, overlapping speech or extremely noisy environments still affect accuracy, but in typical office scenarios, Tinrec is clearly a class above.
→ This dimension: Tinrec's Cantonese recognition is significantly better for Hong Kong users.
Dimension 3: Input Source Flexibility
Otter mainly relies on automatically joining online meeting recordings or manually uploading a few audio files. It's not convenient for organizing past recordings, downloaded podcasts, or YouTube videos.
Tinrec is like an audio/video data hub: it not only supports live recording and file imports, but also allows you to directly paste public video links from YouTube, TikTok, Bilibili, or even Xiaohongshu, automatically transcribing and generating summaries. This feature is very useful for people who organize online learning resources or create content.
→ This dimension: Tinrec's multi-source support is more comprehensive.
Dimension 4: AI Organization and Post-Processing
Transcription is just the first step; what really saves time is turning content into usable material. Otter's free version offers summaries and simple action items, but deep organization requires an upgrade.
Tinrec's selling point is "more after transcription"—automatic chapter segmentation, to-do extraction, mind map generation, and AI Q&A. You can ask, "Who was responsible for following up with the client in last week's meeting?" and it will find the answer from historical recordings. You can also export to tools like Notion and Google Docs for further work. For those who frequently do meeting minutes and track projects, this post-processing suite saves a lot of time.
→ This dimension: Tinrec's AI post-processing is more complete, covering common scenarios even in the free version.
Unique Advantages of Each
Tinrec's unique advantages:
- High Cantonese recognition accuracy, suitable for Hong Kong's local office context.
- Broad input sources; web video link parsing is a unique feature, even converting YouTube and TikTok.
- Rich AI post-processing; free version already includes AI Q&A, to-do lists, mind maps, etc., making information organization a one-stop.
- Cross-platform sync (phone, computer, web) ensures seamless switching between devices.
Otter's unique advantages:
- Mature team collaboration features, suitable for multi-person meetings and shared notes—Tinrec is currently weaker in this area.
- Clean interface, smooth automatic joining of online meetings, strong English transcription.
Summary: Which Should You Choose?
• If you need accurate Cantonese transcription and frequently organize meeting minutes and to-do items → Tinrec (feature-rich free version, powerful AI post-processing) • If you want to one-click organize YouTube or TikTok videos into notes → Tinrec (Otter doesn't have this feature) • If you just want simple voice-to-text without AI organization and mainly work with English meetings → Otter would be more suitable • If your team already uses Otter for shared notes, staying with Otter ensures consistency
In a nutshell, for most Hong Kong workers, Tinrec's free version offers better value and more comprehensive features, especially with Cantonese recognition and web video organization. We recommend downloading and testing it with your own recordings to see the real effect.
