Whisper
WhisperAI is a browser-based transcription service for audio and video. Its features page says it uses OpenAI Whisper technology. The service's branding includes the phrase Official Whisper AI, but this listing is for whisperai.com, not an OpenAI product page. Check the provider you are signing up with before sharing a recording.
Try a file within the actual upload allowance
The homepage's free preview accepts a file up to 25 MB and previews the first five minutes. Elsewhere, the service advertises audio and video uploads up to 5 GB, bulk uploads and unlimited transcription. Confirm which plan provides the larger limit and any usage conditions before moving an archive into it.
File size is one concrete comparison with Whisper Web, which lists up to 2 GB on its Pro plan. A large-file allowance may avoid splitting a recording, but it does not establish better recognition quality. Compare the permitted size and transcription allowance against the length of your recordings before choosing a service.
WhisperAI lists MP3, WAV, M4A and MP4 among supported formats. Start with a short representative passage containing the accents, background noise or overlapping speech present in the full recording. Its claims of high accuracy and perfect speaker labeling are vendor claims, so inspect the transcript before depending on them.
Correct the transcript before using its summary
The features page describes speaker labels, automatic language detection across more than 100 languages and word- or sentence-level timestamps. Its online editor supports corrections, search and replace, and changing speaker names. These controls matter when a speaker's name or a quoted statement will appear in published work.
The service also generates summaries, key points and action items. Check them against the relevant passage of the recording, especially before treating an inferred action as a commitment someone made. For subtitles, the listed SRT export offers timestamps that still need checking against the video. Other listed exports include PDF, DOCX and plain text.
Review access and retention for sensitive recordings
The homepage advertises a meeting assistant, cloud-file transcription and MCP access from Claude and ChatGPT. Confirm the supported connection and permissions for your intended workflow instead of assuming that a feature label grants unrestricted access to every file.
WhisperAI makes encryption and privacy claims on its features page. Review the current privacy terms and retention settings before uploading interviews, client calls or confidential meetings. The demo's stated one-hour deletion rule should not be assumed to cover all account recordings or transcripts. Obtain any necessary participant consent and keep your own original recording.
