Áudio e voz · alternatives
CastReader limits show up quickly for heavy listeners. Free is capped at 20 minutes of listening and 3 AI explains per day, with playback speed up to 1.25x, so serious readers pay. Even on Pro, cloned-voice playback is limited to 120 minutes per month, and the Voice API is billed separately from the reading plans.
ElevenLabs is the voice-focused alternative: text-to-speech, cloning, dubbing and voice agents, with Starter (Creative) at $6 per month and a free tier. Descript edits video and podcasts by text and includes voice cloning, Hobbyist at $16 per editor per month billed annually. Otter.ai transcribes meetings rather than reading pages aloud, Pro at $16.99 per user per month. Gemini Notebook creates summaries and audio grounded in your own sources, with a free option and no price in our pack.
