In their own words
AudioPod AI
AudioPod AI is an in-browser audio workstation for creating podcasts, audiobooks, music, voiceovers, transcripts, and edited audio. Audiobook Studio accepts PDF or EPUB manuscripts, organizes chapters, narrates them with cloned or studio voices in more than 200 languages, and masters output to ACX specifications. Podcast Studio turns supplied PDFs, articles, or notes into editable episodes with one to four AI hosts; its description says output is grounded only in those sources. Other tools include text-to-speech, voice cloning, prompt-based music generation, stem separation, speaker-labeled transcription, and noise reduction. Developers can connect through a REST API, Python and JavaScript SDKs, or an MCP server. Listed agent clients include Claude, GPT, Codex, Cursor, Continue, Cline, OpenClaw, and Hermes. The free Basic plan provides 1,000 credits per month, about three minutes of text-to-speech, and limits files to 30 minutes and uploads to 500 MB. Paid plans start at $20/mo: Creator lists 200,000 monthly credits and a two-hour file limit. AudioPod says data is encrypted in transit and at rest and that customer audio is excluded from generic training without explicit opt-in.
