Don’t want to wire up OpenAI Whisper API? Drop the file here.
The first 20 minutes of any recording are transcribed free: a recording up to 20 minutes transcribes in full, a longer one is previewed, and a pack from $6 (500 minutes) transcribes the rest and opens every export, and credits never expire.
OpenAI Whisper API compared with its closest alternatives — and with us — on the claims that decide the choice. Anything we can’t source from the vendor’s own pages says “Not verified” instead of a guess.

Common questions
What is the best alternative to OpenAI Whisper API?
It depends on the job. AssemblyAI is the closest like-for-like (Product teams that want transcription + NLP (summaries, topics, sentiment, PII) in one API). If the job is turning a recording you already have into a timestamped transcript, Whipscribe does that: the first 20 minutes are free, and one-time packs from $6 for 500 minutes transcribe the rest of transcript (credits never expire).
Is there a cheaper alternative to OpenAI Whisper API?
Prices in the table above are sourced from each vendor's own pages where we hold a current quote — anything we can't source says 'Not verified' rather than a guess. Whipscribe's one-time packs are $6 for 500 minutes, $12 for 2,000 and $24 for 5,000 — roughly $0.29–$0.72 per audio hour depending on pack size, credits never expire, no subscription.
How is this comparison sourced?
Every claim about a third-party product or API requires a verbatim quote from that vendor's public pages, with URL and check date, logged in our public claims file at whipscribe.com/claims.md. Cells without a current source display 'Not verified'.
