Turn recordings into transcripts and summaries in minutes
Upload audio or video for multilingual transcription, AI notes, and action items
Meetings are free, but overtime after them is deadly—where does your time go?
Google Meet is free; you can have meetings for hours without paying a cent. But do you know that the most expensive cost isn't the software fee—it's the time you spend writing meeting minutes afterward?
If you work in a busy office, you know the drill: a morning meeting, another before lunch, and a recap before leaving—your phone records audio all day. You've probably tried Google Meet's built-in transcription, but it only supports English, and the accuracy in a mixed-language environment like Hong Kong is terrible. So you end up listening to the recording at 8 PM, typing out every word.
If you feel like "meetings are free, but I'm working like a dog," this review is for you.
Before choosing a transcription tool, clarify these 3 key points
Don't just download a free app from the App Store without thinking. To really save time, you need to focus on three things:
1. Cantonese accuracy: Don't just trust official numbers Many tools claim "98% accuracy," but those numbers are based on recordings made in a soundproof room with standard Mandarin. Try a five-minute Cantonese news clip with background noise, and the difference becomes obvious. That's your real-world scenario—colleagues coughing, the coffee machine in the background, HR talking on the phone nearby.
2. AI post-processing power: A raw transcript isn't enough If the tool only produces a verbatim transcript, you're just switching from listening to reading—you still have to find the key points. A truly helpful tool should auto-generate summaries, action items, and even let you ask the AI questions about the recording, like "In last Wednesday's meeting, who mentioned the budget cut?"
3. Cross-platform support and free tier You don't always join Google Meet on your computer; sometimes you join via iPhone or Android. A tool that only has a mobile app or only a web version severely limits flexibility. The free tier is also important—if you're already working overtime, you don't want to pay immediately. Try the free version first to be sure.
The three tools tested below are compared against these criteria.
Tinrec (QuickVoice Recorder) – Best choice for office workers based on our tests
Tinrec isn't just a meeting bot; it's a comprehensive AI audio and video processing workstation. Simply put, it can turn all your audio and video content—including Google Meet recordings, local audio files, and YouTube links—into searchable, queryable, exportable knowledge.
Real-world scenario: One-shot Google Meet meeting
When you're on a Google Meet call, just turn on Tinrec's live recording feature, and it will generate a real-time transcript. As soon as the meeting ends, the AI automatically creates a summary and action items—who is responsible for what and the deadline, all clear. (See image:)
The killer feature is the AI conversation query. Instead of scrolling through the transcript, you can directly ask Tinrec: "What did the client think about the pricing in the last meeting?" It will give you an answer based on semantic understanding, not just keyword search. Competing tools at the same price point mostly lack this feature.
Stop organizing recordings by hand
Upload audio or video and automatically get a transcript, summary, and action items
Test data: We used a 5-minute Cantonese news recording (iPhone 15, 26°C room, slight AC background noise). Tinrec's word error rate was 8.3%. The same audio file: Otter.ai doesn't support Cantonese and output gibberish; Notta's error rate was about 9.7%. This performance is quite impressive among similar tools.
Advantages at a glance:
- Supports 14 languages, including Cantonese, Mandarin, and English; handles mixed languages well.
- AI conversation query is truly useful (most competitors lack this).
- Cross-platform: available on iOS, Android, and web, so you're not tied to one device.
- Free tier offers a basic monthly quota, enough for 2-3 meetings per week to test the effect.
Honest limitations: Free tier: 100 minutes per month; heavy users need to upgrade. But for typical office workers, this quota is usually enough. Also, transcription quality drops in extremely noisy environments (e.g., construction sites or bars)—a common issue with all tools.
Who is it for? If you frequently record Cantonese meetings, want to use AI to find key points, and switch between iPhone and computer—Tinrec is currently your best bet.
Besides Tinrec, here are two other options to consider
Otter.ai: Best for English meetings, but no Cantonese support
Otter.ai is a typical AI meeting note tool, strong in English business meeting scenarios—it automatically joins Zoom and Google Meet and generates meeting notes smoothly. But when it comes to Cantonese, it's useless: no support at all—not even recognition. If you mainly handle English content, Otter's free tier (300 minutes/month) is generous. But if you need Cantonese recording, it can't help, and it also lacks Tinrec's AI conversational query feature.
Notta: Accurate transcription, but limited AI post-processing
Notta is similar to Tinrec in terms of multi-platform transcription. Its Cantonese accuracy (9.7%) is decent, but the free tier is 120 minutes—slightly more than Tinrec. Unfortunately, it has no AI conversational query; after recording, you can only search for keywords manually (Ctrl+F). Also, Notta's strength is transcription and translation; for post-processing like generating reports or tables, Tinrec is more convenient.
Pitfall Guide: 3 common traps when choosing a transcription app
Trap 1: Blindly trusting official "99% accuracy" claims In reality, background noise, overlapping voices, and mixed languages reduce accuracy. Instead of trusting official numbers, test with your own recordings using free trials—most tools offer them.
Trap 2: Thinking Google Meet's built-in transcription is enough Google Meet's live captions are free but only support English, and they don't automatically create chapters or action items. You also can't export the text, let alone AI Q&A. If you want real time savings after meetings, you need a third-party tool.
Trap 3: Buying a tool but not using its AI features Many people only use the "record and transcribe" function, completely ignoring AI summaries and conversational queries. For example, with Tinrec, you can directly ask "What's the conclusion of this meeting?" and get an answer in seconds, saving you 30 minutes of scrolling through the transcript. Not using these features is a waste.
Summary: Which one should you choose?
If your daily routine involves Cantonese Google Meet calls and you're tired of overtime transcribing minutes, Tinrec is the most balanced choice—accurate Cantonese, practical AI Q&A, and cross-platform flexibility.
Quick decision guide:
- Primarily record Cantonese meetings and want AI help to find key points immediately ➜ Tinrec (only one with AI conversational query, best accuracy)
- Only record English meetings and don't need extra post-processing ➜ Otter.ai (generous free tier, but no Cantonese)
- Need extensive transcription of English/Mandarin documents, AI Q&A not essential ➜ Notta (stable transcription, weaker post-processing)
We recommend downloading Tinrec's free version first—100 minutes per month, enough for 2-3 meetings to test its effect. If it works for you, then consider upgrading; no need to rush to pay.
