Resoomer

Resoomer is a free online "cognitive studio" for processing, studying and handling information. It started as a text summarizer that condenses long documents into their main ideas and has grown into a suite that also includes a text editor, text player, synonymizer, paraphraser, text rewriter, translator, spell checker, word counter and text comparator, all working with 66 languages.

You can import documents such as PDF, EPUB, DOCX, ODT and TXT files and move the result from one tool to the next, from summarizing to rephrasing to translating. The core tools are advertised as free with no account required, though some tools apply usage limits with a short cooldown or a login prompt. Resoomer is available on the web, as browser extensions for Chrome, Firefox, Edge, Opera, Brave and Vivaldi, and as the Resoomer REFLEX mobile app for Android and iOS.

It is designed for students, teachers, journalists, writers and people with ADHD or dyslexia, with accessibility features such as text-to-speech with real-time highlighting and text simplification.

Resoomer is free to use. The homepage describes it as free, with no account required and no character limit for its core tools, and the mobile app is described as free with no usage limits.

Some tools, such as the paraphraser and synonymizer, apply usage restrictions: after reaching a quota you must log in or wait about 10 minutes before using the tool again. A premium or account option is implied for extended access, but the pricing pages could not be retrieved, so no official paid plan prices are listed here. Older third-party reviews mention a premium plan around $9.95 per month, which should be verified on the official site.
