Turn recordings into transcripts and summaries in minutes
Upload audio or video for multilingual transcription, AI notes, and action items
Are you constantly interviewing candidates for your company or going to job interviews yourself, then having to listen back to recordings and type up transcripts? Always staying late for overtime? We tested 4 tools on the market and found the most convenient one is Tinrec (Instant Playback). Not only does it transcribe quickly, but it also automatically generates summaries, highlights key points, and even creates a to-do list. Below we guide you step by step on how to use Tinrec for interview recordings, so you never have to stay up late typing transcripts again.
Before You Start | What You Need to Prepare
- A smartphone or computer: Works on iPhone, Android, and web version. Tinrec's multi-platform sync is very convenient.
- Download the Tinrec App: Free download from App Store / Google Play. Login with Google or Apple ID, no complicated registration needed.
- Prepare your interview recording: Can be recorded live on the spot, or a pre-recorded audio file (supports mp3, m4a, wav, etc.).
- Stable internet connection: Real-time transcription requires internet; if interviewing in a basement, it's best to record first and upload later.
Step 1 | Record the Interview
The goal here is to get a clear recording—everything else depends on it.
If you are interviewing in person, open Tinrec and press the red record button, place your phone in the middle of the table, no more than one meter from the speakers. The clearer the audio, the more accurate the transcription, saving you a lot of proofreading time. If it's a video interview (Zoom / Google Meet), use the desktop version of Tinrec to directly record system audio, even filtering out background noise.
Why do this? Because the limit of AI transcription is determined by audio quality. If you record messy audio, no engine can salvage it. Rather than regret later, spend an extra ten seconds positioning the device during recording.
Once done, the main screen will show a new recording with duration and file size.

Step 2 | Let AI Generate a Transcript
After recording, tap the recording file and Tinrec will automatically start transcribing. Typically, for a few minutes of recording, it produces text in about ten seconds. It automatically separates speakers (Speaker 1, Speaker 2) and skips irrelevant filler words.
If you are importing an old recording, go to the "Import" section and select the file. It supports audio and video, even YouTube interview clips (must be public videos). This feature is not available in many tools; Otter only has it in Pro, and Notta limits formats.

Step 3 | Quick Proofreading of the Transcript
AI is not perfect, especially Cantonese sometimes gets it wrong (e.g., '唔該' (thank you) becomes '唔乖'). But Tinrec has a killer feature: it highlights low-confidence words so you can focus check them.
You can listen to the recording while editing the text. Best of all, it supports a "Notes" feature, allowing you to mark key points as you go, such as the candidate's expected salary, notice period, etc.

Proofreading doesn't require going through the whole thing; use the AI summary feature (next step) to find key parts and check those.

Step 4 | Let AI Generate an Interview Summary
This step is where Tinrec leaves competitors behind. It doesn't just produce a transcript; it can generate a structured interview report:
- Press the "AI Summary" button, and it will automatically summarize the key points of the interview, e.g., "The candidate has 5 years of Java experience but limited management experience."
- Use "Task Extraction," and it will output a checklist, e.g., "Prepare the technical test needed before the second round next week."
- Most impressively, "AI Chat Query" lets you directly ask: "Did this candidate mention why they left their previous job?" It will instantly find the answer in the transcript.

Step 5 | Export and Share
After organizing, you can export as PDF, Word, TXT, or even share a link directly with HR colleagues. No more back-and-forth via messaging apps.
If you use Notion or Google Docs, Tinrec can output directly, streamlining the process. This is better than hardware like PLAUD—they require export and then manual copy.

Common Questions and Troubleshooting
Q: The recording has a lot of noise, and the transcription is full of errors. What should I do? Usually, the environment is too noisy. Tinrec has built-in smart noise reduction; turn it on in settings before recording. If you are using a pre-recorded file, you can select the "High Noise Environment" mode after import. Most transcription tools on the market don't have this option; they just use the default mode.
Q: Multiple people talking, and it can't tell who is who? Tinrec's speaker separation works well, especially for in-person meetings, as long as people don't talk over each other. If overlapping is severe, you can manually merge or split paragraphs later. Fireflies and Otter are stronger in English environments, but for Cantonese speaker separation, Tinrec is still the most reliable.
Q: If the interview is in Mandarin or English, can Tinrec handle it? Yes. It supports over 50 languages, including mixed Chinese and English. You can set it to "Auto Detect Language" in settings, and after transcription, you can even translate it with one click.

Advanced Tips | 3 Ways to Double Your Efficiency with Tinrec
1. Use AI Chat to Find Key Points Directly No need to scroll around. Just ask the AI: "What salary is the candidate asking for?" or "Do they have management experience?" Tinrec will find relevant sentences in the transcript and highlight them for you. Competitors like Notta and Otter have AI chat, but most are limited to English; Tinrec is one of the few that supports natural language queries in Cantonese.
2. Build an Interview Database Keep recordings and summaries after each interview. Months later, you can search past candidates. For example, search for "applicants who know Python," and Tinrec will search across recordings. This feature is not even possible with PLAUD—they have a hardware mindset and lack cloud-based long-term storage.
3. Cross-Platform Handoff Record on phone, organize on computer. Tinrec automatically syncs everything; you can mark key points on your phone during the commute, and when you open your computer at the office, it's already updated. Unlike some tools that require manual export and import.
If You Don't Use Tinrec, Here Are Other Options
- Otter.ai: Strong in English, but Cantonese transcription has many errors, and the free version only has 300 minutes. Suitable for companies with all-English interviews.
- Notta: More minutes, but the AI summary after interviews is basic, lacking AI chat query. Suitable for users who only need cheap transcription.
However, if you need a one-stop solution for recording, transcription, report generation, and searching past records, Tinrec remains the most comprehensive choice.
Summary
By mastering these 5 steps, you can turn any interview recording into text, automatically generate summaries and to-do lists, and even use AI to ask for key points. No more overtime listening to recordings, and you can build your own talent database. Next step: Download the free version of Tinrec, try it with an old recording. The monthly allowance is enough for several interviews. Getting off work early is the real win!
