Reedle is a digital reading platform designed to help users engage deeply with academic papers, articles, and other long-form content across devices. It addresses the challenge of retaining information from saved readings by integrating AI chat, spaced repetition, and advanced rendering features into a single experience. The tool is aimed at those who take reading seriously, such as students, researchers, and language learners, and supports workflows for language learning, academic reading, and habit tracking.

Key capabilities include PDF and formula rendering (with LaTeX and MathJax), AI-powered chat for summarizing and explaining content, and a built-in spaced repetition system based on the FSRS algorithm. Reedle also offers listen mode to convert readings into audio with neural voices, contextual translation and grammar analysis, and interactive video transcript support for platforms like YouTube and Bilibili. Users can track reading habits with daily streaks, receive weekly digests summarizing key highlights, and share collaborative reading lists. The platform provides universal import for EPUBs, PDFs, and web articles, bulk import from Zotero, and a library-wide AI search across saved content, highlights, and comments.

Reedle is accessible via a web app, native iOS and Android applications, a Chrome and Edge browser extension, and offers offline sync and PWA support for reading without internet access. For developers and advanced users, it features a terminal CLI for saving articles and searching the library, an open API for exporting highlights and integrating with tools like Obsidian and Zotero, and the MCP Server for connecting to external AI assistants such as Claude or Cursor. Theming options are available for reading comfort, including white, sepia, and dark modes.

The service offers a 30-day free trial with no credit card required and allows users to cancel anytime. Reedle positions itself as a comprehensive solution for deep reading, active recall, and information retention, integrating tools and workflows that support both individual and collaborative learning.
