Download of Excerptor 1.1.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Chen Guo. We recommend checking the downloaded files with any free antivirus. The application relates to Productivity Tools.
From the developer:
Excerptor lets you take and locate excerpts in PDF files quickly. When you read a PDF file, you may want to take some excerpts, like excerpting on physical books (including article name, page number, etc.). Via Excerptor, you can take excerpts easily: select text in Preview/Skim and type a shortcut. An excerpt will be stored in the pasteboard or in a file. The excerpt includes a special link.
You may want to check out more Mac applications, such as Mail to ToDo X, FOGT or Remote Buddy Express, which might be similar to Excerptor.
