Audify vs Twocast

Audify is a free, open-source application that turns PDF, DOC and DOCX files into editable two-speaker podcast scripts and downloadable MP3 episodes. It extracts document text and can use OCR when a scanned PDF yields little text. Users review and revise speaker turns, wording and flow, choose host and guest voices, and select conversational, educational or professional tones before generating audio. Ollama is the primary script-generation route, with OpenAI as a fallback; an OpenAI API key is required for text-to-speech, while Ollama is optional. The TTS service creates speech for dialogue turns, combines it into MP3, and supports playback and download. Audify uses FastAPI microservices with a React and Vite frontend and is orchestrated for local Docker Compose deployment. Its API handles uploads, generation, job status and downloads. Docker Engine 24.x or later and Docker Compose Plugin v2 or later are required. Uploads are limited to 10 MB, and jobs reset after container restarts unless storage is added.

Twocast is an AI podcast generator that turns source material into two-person audio conversations. Users can supply a topic, URL, PDF, Word document, text file, or pasted plain text. Two distinct AI personalities create dialogue, and settings control episode length, style, tone, and host personalities, including casual, professional, and educational options. Twocast describes the output as broadcast-quality audio with natural pauses and conversational flow. Most results are ready in 2–5 minutes, depending on content length and complexity. Short articles may become 5–10 minute episodes, while comprehensive documents may produce 20–30+ minute podcasts. Finished audio can be downloaded as standard files and edited with audio software. The service currently specializes in English conversations, with more language support in development. Businesses use it for reports, training, and marketing; educators can turn lectures and articles into audio. The Free plan is free, billed one-time, with 10 credits, up to one audio, priority generation, and 30-day validity. Starter is $9, paid once, billed one-time, with 900 credits and up to 90 audios.
