Overview
Speechify
Speechify helps you turn any written text into high-quality audio so you can listen while you commute, exercise, or multi-task. Whether you are dealing with a long PDF for work, a physical book you need to scan, or a web article, you can instantly transform it into a spoken track. It uses advanced AI to provide human-like voices that make listening feel natural rather than robotic.
You can adjust reading speeds up to 4.5x to power through content faster or slow it down to aid comprehension. The platform is designed for students, professionals with heavy reading loads, and individuals with dyslexia or visual impairments. By syncing across your phone and computer, you can start a document at your desk and finish it on your walk using the mobile app.
Synthesia
Synthesia helps you turn text into professional-quality videos in minutes. Instead of hiring actors, booking studios, or using expensive camera equipment, you simply type your script and choose from over 140 diverse AI avatars to deliver your message. It is designed for teams who need to produce consistent, high-quality video content at scale for training, sales enablement, and internal communications.
You can customize your videos by adding your own backgrounds, images, and screen recordings directly within the browser-based editor. The platform solves the common problem of video production being too slow or expensive, allowing you to update content instantly by just editing the text script. It is widely used by L&D professionals and marketing teams who want to replace text-heavy documents with engaging video content.
