Transcriptly

The core draw is pulling transcripts from YouTube. If a video has captions, Transcriptly grabs them through YouTube's public API and returns a timed transcript in seconds, no AI processing needed and no video download. That covers the bulk of popular content, where captions already exist. The catch is coverage: videos without captions fall back to AI recognition, which is slower and costs minutes rather than a single credit.

For files on your device and for YouTube videos that lack captions, the service runs AI speech recognition. It works as a speech to text tool for the formats people actually record in, including AAC, MP3, M4A, WAV, and OGG for audio, and MP4, MOV, MKV, AVI, and WebM for video. The AI step also adds speaker detection, which labels each voice as Speaker 1, Speaker 2, and so on. That matters for interviews and panels, where a wall of text with no attribution is hard to use.

Transcriptly handles 98+ languages, and the language picker lets you target a specific one. For captioned YouTube videos with several language tracks, you can switch between them, but each switch spends another credit. For research that crosses borders, this means foreign lectures, interviews, and press material become readable without a separate translation service, and the AI summary works on the other-language text too.

Beyond the raw text, the tool summarizes a transcript and lets you ask questions about it. You can pull key points, condense an hour of talking into a short brief, or query the content for a specific topic. It's useful when you need the gist of a long recording before deciding whether to read the whole thing. The summary quality tracks the transcript quality, so a noisy recording gives a thinner brief.

Transcripts come out in the formats different workflows need. TXT for plain reading, SRT and VTT for video subtitles, CSV for spreadsheets and analysis, and PDF or DOCX for documents and reports. That range means one transcript can serve a video editor, a writer, and an analyst without re-processing. Sharing is covered too, through a link you can pass to a teammate.

Transcriptly ships an API for batch and programmatic work. Developers can request transcripts by video ID or URL and get structured output back, which suits teams building a pipeline or processing content at volume. Access sits behind the paid plans, and each call spends a credit, so cost scales with volume. It's aimed at professional users rather than one-off jobs.
