What "online transcription" actually means

Online transcription runs entirely through a website. You open the app, upload an audio or video file, and the service converts speech to text on its servers — then you download the result. There is no app to install, no plugin, and no local processing power required. That makes it the fastest way to handle a one-off interview, lecture, or podcast episode from any computer.

PlainScribe is file-based: you upload a finished recording and get a transcript back. It is not a live meeting bot that joins calls, and it is AI-only (no human typists). For sensitive material you can also run the offline desktop app, but for most jobs the browser workflow below is all you need.

How to transcribe audio to text online

Step 1: Open the app and start free

Go to the transcription dashboard and sign up. You get 30 free minutes with no credit card, so you can test accuracy on your own audio before paying anything.

Step 2: Upload your audio file

Drag your file into the browser or click to select it. PlainScribe accepts MP3, MP4, WAV, M4A, MOV, WebM, MKV, AAC, FLAC, OGG and other common audio and video formats, up to 200MB per file. For long recordings, a mono MP3 at 64–128 kbps keeps the file small without hurting speech accuracy.

Step 3: Let it detect the language and run

Choose the spoken language or let PlainScribe auto-detect it across 47 supported languages. Click transcribe. The AI engine processes the file in minutes; you do not have to stay on the page.

Step 4: Review the transcript online

When the job finishes, your transcript opens in the browser. Skim it and fix any misheard names, acronyms, or numbers — automated transcription is up to 99% accurate on clean audio, but a quick review still pays off.

Step 5: Export or download

Download your transcript as TXT for documents, CSV for timestamped data, or SRT/VTT for video captions. You can also generate an AI summary from the same file.

Is online transcription free?

You can transcribe your first 30 minutes free with no credit card. Beyond that, PlainScribe charges $0.067 per minute ($4 per audio hour) on a pure pay-as-you-go basis — no subscription and no per-seat fee. The minimum top-up is $10 (about 150 minutes of credit), and paid credits last a full year. Many "free" online tools cap you at a few minutes, watermark output, or require a monthly plan to export. Here is how the options compare:

| Service | Model | Price | Free tier | Notes | |---------|-------|-------|-----------|-------| | PlainScribe | Pay-as-you-go | $0.067/min ($4/hr) | 30 min, no card | Subscription-free; 7-day auto-delete | | Sonix | Hybrid | ~$0.167/min PAYG or $22/mo | 30 min trial | Higher per-minute rate | | Rev | Pay-as-you-go | $0.25/min AI | None | Pricier AI tier | | TurboScribe | Subscription | $10/mo | 3 files/day | Monthly commitment | | Otter.ai | Subscription | Free tier + paid Pro | Limited free tier | Live-meeting focused, per-seat |

Verdict: If you transcribe occasionally and want to avoid a recurring bill, PlainScribe's pay-as-you-go pricing is the cheapest honest option — you pay only for the minutes you actually upload, and the first 30 are free.

Why browser-based beats installed software for most people

You skip downloads, updates, and operating-system compatibility headaches. You can transcribe from a Chromebook, a work laptop with locked-down installs, or a phone browser. And because PlainScribe deletes your files and transcripts after 7 days, you are not leaving a permanent archive on someone else's server.
