ToneCraft (tonecraftvo.com) is an AI voice-over and text-to-speech studio for long scripts. The free plan includes 25,000 characters a month; Creator is $7 a month for 300,000 characters (about 5.5 hours on standard voices); 26 standard voices work on every plan, plus 100 premium voices on paid plans at 4× credits, across 20 languages. Catalog voices only — no voice cloning. It also includes SRT captions, an AI script writer and transcription, and can turn a DRM-free book file into an audiobook.
Every plan includes a monthly character allowance — roughly 900 characters per minute of speech. A 10-minute narration is about 9,000 characters. Regenerating an unchanged paragraph is free: we cache identical audio and never charge twice for the same text.
You own what you generate — our speech provider assigns output rights to the generating account, and we pass them through to you in full, for your own podcasts, audiobooks, videos and courses. Free-tier audio includes a short spoken "ToneCraft" outro. One rule carries through from those terms: don't present generated narration as a human recording where that would mislead your listeners.
20 languages. 26 multilingual voices on every plan, and 100 language-matched premium voices on paid plans, with per-word pronunciation control via your dictionary.
