Drop in up to 50 audio or video files at once and we'll transcribe them in a single batch. Perfect for podcasters, agencies, researchers, and anyone with a backlog.
Drag your whole folder. Up to 10 hours and 5 GB per file.
OpenAI's flagship speech-to-text — 100+ languages, robust to noise.
TXT, DOCX, PDF, SRT, VTT — individually or as a batch ZIP.
Bulk audio transcription is the practice of converting many audio or video files into searchable, exportable text in a single batch — instead of uploading and processing each file one at a time. For podcasters, agencies, researchers, journalists, and anyone with a backlog of recordings, the difference between a one-at-a-time workflow and a batch workflow is the difference between weeks of work and an afternoon.
Under the hood, every file you upload runs through OpenAI's Whisper — the gold-standard speech-to-text engine. Whisper handles 100+ languages, tolerates background noise, recognizes accents and code-switching, and produces transcripts with word-level timing data. We accept every common audio and video container: MP3, M4A, WAV, OGG, FLAC, MP4, MOV, WEBM, OPUS, and more. Files of up to 5 GB and 10 hours each are supported.
Most podcast back-catalogs are dark to search engines. The audio exists, but the words inside aren't indexed. Running an entire show through bulk audio transcription gives you instant searchable archives, makes scaled show-notes generation possible, and unlocks AI-driven repurposing into newsletters, clips, and social posts.
If you run an audio production studio, content agency, or any service business with recurring client recordings, bulk transcription removes a major bottleneck. Onboard a new client's entire library overnight.
A single qualitative-research project might involve 80 interviews of 60–90 minutes each — that's over 100 hours of audio. Bulk transcription turns weeks of manual work into a few hours, with output ready for NVivo, Atlas.ti, or any qualitative analysis tool.
Depositions, recorded statements, compliance call reviews — bulk Whisper transcription beats outsourced services on speed, cost, and confidentiality. Everything stays inside your account.
A deep investigative piece might involve 30+ recorded interviews. Bulk audio means the reporter spends time on the story, not on typing or hand-correcting outsourced drafts.
Building captions for an entire corporate training library, a learning platform's curriculum, or a marketing video archive used to be a multi-week project. With bulk audio + SRT/VTT export, it's a single afternoon's work.
Industry conference recordings, earnings calls, expert interviews, focus group sessions — bulk audio lets you build a searchable intelligence layer over an entire field's spoken-word output.
Recorded patient consultations, dictated notes, telemedicine sessions — bulk transcription accelerates documentation workflows while keeping data inside your account.
Click the upload area or drag-and-drop files directly. We accept up to 50 files per batch, with no requirement that they be the same format — mix MP3 podcasts with MP4 videos with M4A voice memos all in one upload.
Pro users see their batch start the moment they hit submit. Free users see their batch parked as Awaiting Payment in their Bulk Jobs dashboard. The moment you upgrade, the entire batch releases automatically — no resubmission, no lost uploads.
Each file shows live status: Pending → Processing → Success or Failure. Whisper transcribes at roughly 5–10% of real-time — a one-hour podcast takes about 3–6 minutes.
Plain text (TXT), Microsoft Word (DOCX), PDF, or SRT/VTT subtitles. Pro users can also batch-export the entire job as a single ZIP archive for handing off to clients or archiving.
Failed items don't block the rest of the batch — each file runs independently.
Up to 50 per batch. Submit multiple batches for larger jobs — they run in parallel on our worker pool.
Whisper runs at roughly 5–10% of real-time. A batch of 50 thirty-minute files typically finishes in 60–90 minutes total, with files processing in parallel.
MP3, M4A, WAV, OGG, FLAC, AAC, OPUS, WMA for audio. MP4, MOV, WEBM, MKV, AVI for video (we extract audio automatically). If you've got something unusual, try it — we accept most things ffmpeg can decode.
5 GB per file for Pro users. Free users hit the paywall above 50 MB. Files larger than 5 GB should be split.
10 hours per file. For 24/7 stream recordings, split into chunks first.
Whisper auto-detects 100+ languages out of the box. No language selection needed — just upload.
Yes — we store source audio in object storage (Wasabi) so you can re-export or re-process. You can delete any file from your file manager at any time.
Yes — retry from the file manager. Useful when failures were transient (network glitch, temporary capacity issue).
Files are stored privately in your account. We use industry-standard encryption at rest. See our privacy policy for full details.
Scroll up, drop in your files, hit Start Processing. Your first batch will show you the whole flow in under a minute — the upload is fast, the processing is parallel, and the file manager has everything when you come back.
