Weava Highlighter

Weava Highlighter is a research annotation tool for collecting and organizing highlights from webpages and PDFs. It is best for students and researchers who want citations and export options alongside their notes. Its broad capture and organization tools are useful, but the free plan’s 100 MB storage cap and gaps in file compatibility may rule it out for some workflows.

Overview

Weava brings web and PDF annotation into a dashboard built for sorting and reusing research. You can highlight websites, online PDFs, local PDFs, and PDFs uploaded to Weava, then attach notes to individual highlights; Weava says notes have no length limit. That mix suits research spread across browser sources and documents, rather than a workflow focused only on saving webpages.

Folders, sub-folders, search, and color filters help keep a collection navigable. The dashboard can create citations and export work to Microsoft Word, Excel, CSV, or TXT, which gives users practical ways to move collected material into writing or analysis. Compatibility is the main caveat: Weava does not directly support highlighting Google Drive or Google Classroom files, and some websites may conflict with its highlighter.

Key features

Capture and organization

Weava’s support for webpages and several PDF sources makes it flexible for mixed-source research. Search and color filtering add useful ways to find passages later, while folders and sub-folders provide structure. Free users get five default highlight colors; Premium adds unlimited colors and unlimited sub-folders. The latter matters most to people managing a large or finely categorized archive.

Citations, exports, and collaboration

Citation creation and exports to Word, Excel, CSV, and TXT help turn annotations into material for other work. Premium shared folders let users invite collaborators by email to view and work with highlights and notes, making the paid plan more relevant for shared research. Users who need only personal annotation may get less from that upgrade.

Pricing

Weava uses a freemium model, with a free plan and Premium at $3.99 a month, billed $3.99 / month.

The free plan provides the core annotation and syncing tools, but 100 MB can constrain users who upload or keep many PDFs. Premium removes the storage ceiling and expands organization and collaboration, so it is the better fit for heavier or shared research collections. Both plans include unlimited highlights and notes; the paid upgrade is chiefly about capacity, flexibility, collaboration, and support.

Weava says billing is processed through Stripe and that it does not directly handle credit card information.

Platforms

Weava is available as a Chrome extension and an iOS app. Its resources also describe use with recent Microsoft Edge versions that support Chrome extensions. The iOS app extends access to mobile devices, while the browser extension is central to capturing web material.

Who it's for

Weava suits students and researchers who collect material across websites and PDFs and want a single place to annotate, organize, create citations, and export work. The free plan is a reasonable starting point for lighter collections and personal use. Users with large PDF libraries, a need for more color and folder options, or collaborators will have a clearer case for Premium.

It is a weaker fit for workflows centered on Google Drive or Google Classroom files, or for users who depend on every site working consistently with a browser highlighter.

Pros and cons

• Broad source support: highlights work across webpages and online, local, or uploaded PDFs, which suits research drawn from varied sources.
• Useful ways to retrieve and reuse material: folders, sub-folders, search, color filters, citations, and multiple export formats support work beyond initial capture.
• Free syncing and annotation: the free plan allows unlimited highlights, notes, and device syncing, but its 100 MB storage cap can limit larger document collections.
• Collaboration is Premium-only: shared folders support email-invited collaborators, but teams need the paid plan for that workflow.
• Compatibility gaps: Drive and Classroom files cannot be highlighted directly, and some websites may conflict with the tool.

Verdict

Choose Weava if you are a student or researcher who needs to annotate both websites and PDFs, keep the results organized, and carry them into citations or exported files. Its free plan covers a substantial core workflow, and Premium makes sense when storage, customization, or collaboration becomes important. Look elsewhere if your research depends on direct highlighting of Google Drive or Classroom files, or if the 100 MB free limit is too restrictive and you do not want a paid plan.
