Actually saves me copying text into chatgpt every time.
Decent highlight sync, but wish the tag sorting was faster.
Good workflow addition for research.
A bit clunky when jumping between multiple sites.

Turn highlights into answers with free-form prompts or 40+ scenario and industry templates powered by GPT-4, GPT-3.5, Claude or Bard.

Send highlights to TrendsCritical.com, group them by website, and export them as Word documents using preloaded templates.
Highlighter for TrendsCritical.com is a browser extension offered by the trend-research service TrendsCritical.com. Rather than being a plain marker tool, it treats every highlight as a research artefact: selected text is stored in the browser, listed in the extension popup with dates and custom tags, and can be pushed to a TrendsCritical account for longer-term analysis.
Three highlighting flows are supported — a configurable keyboard shortcut, a right-click context command, and a start/finish highlight mode for collecting several passages in one pass. Highlights restore automatically when you return to a page, although dynamic or heavily updated pages may not restore cleanly; in those cases you save them to TC Documents and export as a .docx file.
The analytical layer is what sets it apart. You can write free-form prompts or pick from more than 40 scenario-based and industry templates, and run them against commercial language models such as GPT-4, GPT-3.5, Claude or Bard. Pro and Power users also get document templates, including frameworks for turning trend research into action plans, an AI workflow enhancer and a second-brain mental-model extractor. Free users receive up to 1,000 AI credits after signing up, and no separate ChatGPT or Claude account is required.
Highlight passages across industry news, reports and blogs, then run templates that surface emerging workflow, lifestyle and productivity shifts.
Collect competitor and audience observations in one pass and analyse them with the Trends into Actions framework to produce concrete next steps.
Tag highlights by theme, revisit them per website, and use the mental-model template to extract hidden insights from long-running reading.
