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.
70x faster Whisper on TPUs via JAX + Flax + batching.
Best for bulk transcription on TPU pods or A100 clusters where JAX shines. Pricing: free.
What it is
A drop-in JAX re-implementation of OpenAI Whisper that batches across the time dimension and reports up-to-70x speedups on TPUv4. MIT-licensed; the canonical choice when you have JAX infrastructure already.
Watch out for: JAX/TPU setup is non-trivial; CPU/MPS inference is slower than faster-whisper.
