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.
Performance fork of Tortoise — quality kept, latency 5-10x lower.
Best for researchers + indie devs who want Tortoise-quality output without the 30-90s-per-clip baseline. Pricing: free.
What it is
tortoise-tts-fast applies inference optimizations (key-value cache, kv-cache float16, batch generation) to the original Tortoise model. Same quality, dramatically faster. Listed for the OSS-stack reader who's already evaluating Bark / XTTS / F5.
Watch out for: English-only (same as upstream Tortoise). Tortoise outputs ship with a model-author disclaimer about consent for voice cloning — keep it. Maintenance is community-effort; not a vendor SLA.
