Audify vs Tider

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.

Tider turns PDFs, articles, and personal documents into podcast-style audio on Mac or iPhone; it also makes audiobooks in the cloud. Sources can include PDFs, DOCX files, URLs, and RSS feeds. Episodes can use a single narrator or a host-and-guest format, with controls for narrator persona, audience, tone, pacing, and focus areas. Podcasts and summaries are generated on-device and can work offline after the language and voice models have been downloaded. Tider can also follow RSS feeds and URLs, crawl them, and convert them into an audio queue. Its Free plan costs nothing and includes unlimited on-device podcasts and summaries, unlimited cloud audiobooks, source imports, and plans saved locally. Audiobooks are generated on Tider’s servers. Tider says documents, scripts, and generated audio are processed and stored locally rather than uploaded; Pro cloud sync stores saved plans across Mac and iPhone, not documents or audio. Downloads are listed for macOS, Linux, and iPhone. Tider says it receives an email address when a user creates an account or enables Pro cloud sync, and holds no personal data if the user never signs in.
