Rev AI

ten cents an hour — the cheapest number in this ranking, attached to the least complete pricing page.

$0.10/hr#large-batch-archives-whe#english-is-the-main-lang

less than half assemblyai's rate and a third of whisper's, with real-time pricing and diarization costs that simply aren't published.

$0.10 an hour on reverb turbo is the lowest published rate anywhere in this ranking, with the standard reverb model at $0.20 and whisper-based options at $0.30. free credits equivalent to five hours of reverb make it cheap to evaluate.

rev describes reverb and reverb turbo as open-source models, which would give it a self-hosting path alongside whisper's — but we could not confirm the licence or repository within budget, so treat that as a promising lead rather than a fact. its marketing cites gains 'over competitors' rather than an absolute error rate against a named dataset, so there's no accuracy figure here we'd publish.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
