GreenConvert

Messy recordings, unclear speech and hours of manual typing are what GreenConvert is built to cut down.

GreenConvert is an AI transcription and audio enhancement tool that turns speech in audio and video files into text, cleans up noisy recordings and converts media between formats.

It claims 98% transcription accuracy and covers more than 98 languages, which makes it relevant if your material is not in English.

Beyond plain transcripts, GreenConvert separates speakers through speaker diarization, so interviews and meetings are easier to read afterward.

Its neural audio upsampling reduces background noise and improves speech clarity before or alongside transcription.

The platform also handles video processing at up to 8K, and its categories include subtitle generation, translation and video translation, so one account can cover captions and multilingual versions of the same file.

The main promise is also environmental.

GreenConvert says it runs on sustainable computing infrastructure with a neutral carbon footprint, a claim you would need to take on trust.

The accuracy figure is the company's own, so test it on your own audio, especially with heavy accents or crosstalk, before relying on it.
