24 alternatives to Side Reader
Side Reader is a Chrome extension that lets you read and interact with PDFs directly on ChatGPT, Claude, and DeepSeek websites. I built Side Reader because I got tired of the constant tab-switching between PDF readers and AI chat - copying text, switching tabs, pasting, repeat. It was driving me crazy. Over time, I added more features like custom highlight buttons, screenshot functionality, and local storage.

Speed Reader▲99I built a Chrome extension for speed reading using RSVP (Rapid Serial Visual Presentation).

That's how Speed Reader was born — a free Chrome extension that lets you read faster right in your browser. The main feature is automatic article parsing. Open any page, click one button, and the extension extracts the text, removing ads and clutter. It also highlights the ORP (Optimal Recognition Point) — the natural focus point in each word. Free, no ads, no data collection.…
