Abogen is a software that converts EPUBs, PDFs, and text into audiobooks with synchronized captions.

The software is designed to be user-friendly and efficient, making it a great tool for content creators and publishers.

Speechify is a text-to-speech and voice productivity app that converts written content such as documents, PDFs, articles, and ebooks into natural-sounding audio across 60+ languages and 1,000+ voices, with adjustable playback speed up to 5x. It includes OCR-based document scanning, AI summarization, and a voice assistant that can answer questions about the content being read. The app also offers voice typing and dictation, AI-generated podcasts created from documents, and meeting transcription, and is available on iOS, Android, Windows, Mac, and as a Chrome/Edge browser extension. Speechify markets heavily to students, professionals managing heavy reading loads, content creators, and people with dyslexia or other reading-related accessibility needs -- its founder built the product after his own dyslexia diagnosis.
