Excerlo in action
A guided tour of the extension: capture, notes, comparison and export, narrated in English.
Meet Excerlo. Highlight useful passages, keep their sources, and turn your reading into organized research. Let’s see how it works, using two fictional tools.
On a webpage, select the passage you want to keep. Choose a color, a folder, and a section, then click Capture. Your excerpt and its source are saved together.
In your library, find your excerpts and add your own analysis. Your note saves automatically. In Outline view, find your passages grouped by section and write your summary.
Reading more than one source? Compare view, included in Pro, brings their excerpts together by criterion. Here, the prices and benefits of our two examples appear side by side.
Your research is ready. Choose a format and export your work with its notes and references. Markdown and CSV are free. Pro also includes Word, HTML, and a print view you can save as PDF.
To move faster, create a list of words or phrases. Excerlo highlights matches as you read. Use a shortcut to move to the next match, then choose which passages to keep.
Excerlo works in English and French. Your folders stay in your browser, with optional encrypted syncing. Try the interactive demo on our website.
