Experience

  • Pintellect (Development)
    http://www.pintellect.io

    Pintellect is a targeted information sharing platform.

    Overcome the inundation of content in linear feeds by focusing on the key highlights and takeaways.

    Highlight and annotate the key nuggets of content within any external web article, PDF, or website as it relates to your organization or immediate teammates. Add context on the information by creating annotations, visible on the source website via the browser extension. Establish permissions on who can see your content within your network. Notify teammates in comments and annotations by @name mentioning them via Slack, Teams, and Workplace. Organize the key takeaways using personal or collaborative pinboards. Create an on-going, searchable repository of content.

    Working with Chrome Extensions was something I did heavily to interact with web page content. I did a sidebar that made able for the browser to highlight and create annotation on top of any webpage opened on Chrome. Here is the extension link: https://chrome.google.com/webstore/detail/pintellect/aegkndgccfaapcfdbmejcicaglalnafh
