The best AI transcription tools in 2025 — compared
AI transcription has come a long way in the past two years. What used to cost £1 a minute from a human transcription service now costs fractions of a penny and comes back in seconds. But not all tools are the same — accuracy, pricing, and output formats vary significantly.
Here's how the main options compare in 2025.
The tools at a glance
| Tool | Price | Output formats | Best for |
|---|---|---|---|
| FileSense TranscribeThis tool | From $5 (credits) | TXT, SRT, DOCX | Users who also need image renaming |
| TurboScribe | $10–$20/month | TXT, SRT, DOCX, PDF | High-volume transcription only |
| Otter.ai | $8.33–$20/month | TXT, PDF | Meeting notes & live captions |
| OpenAI Whisper (self-hosted) | Free (requires setup) | TXT, SRT, VTT | Technical users comfortable with code |
Accuracy — does it matter which you choose?
TurboScribe, FileSense Transcribe, and most modern tools all use OpenAI's Whisper model under the hood. This means accuracy is essentially identical between them on clean audio. The difference comes with accents, background noise, and technical vocabulary — where Whisper's large-v3 model performs noticeably better than smaller versions.
Otter.ai uses its own proprietary model which performs well for meetings and multi-speaker conversations, but can struggle with single-speaker audio that isn't a standard American or British accent.
Pricing — the real comparison
TurboScribe charges a monthly subscription whether you use it or not. If you transcribe 10 files one month and zero the next, you've still paid. FileSense uses credits — you buy them when you need them and they never expire. For irregular users this is significantly cheaper.
For very high-volume users (daily transcription), TurboScribe's unlimited plan likely works out cheaper. The break-even point is around 200 minutes of audio per month.
Output formats — what you actually get
Most tools give you plain text. The formats that matter beyond that are:
SRTSubtitle format — essential if you're adding captions to video content for YouTube or social media.DOCXWord document — useful if you're sharing with clients or editors who need to annotate the transcript.VTTWebVTT — subtitle format used by web video players. Less common but important for web publishing.
Our verdict
For most people, the choice comes down to how regularly you transcribe. If it's a daily workflow, TurboScribe's unlimited plan is worth considering. If you transcribe occasionally — a few podcast episodes a month, client interviews, meeting recordings — a credit-based tool like FileSense is more sensible. You're not paying for months where you don't use it.
The advantage FileSense offers that others don't is combining transcription with AI image renaming in one platform — useful if your workflow involves both.
