In their own words
Huddlekit
Huddlekit is a visual annotation and QA tool for designers, developers, and clients reviewing websites, web apps, images, PDFs, and video. Comments on websites and web apps capture a screenshot and context such as the page, clicked element, browser, device, and viewport. Guests can comment through a shared link without an account or browser extension, and guest access is unlimited on every plan. Comments can be tracked on a project Kanban board and assigned owners, priorities, due dates, and effort estimates.
Inspect mode shows sizing, spacing, and alignment on a live website without opening developer tools. Pro and Team add side-by-side breakpoint review, custom breakpoints per project, and connections to Claude, Claude Code, or Cursor over MCP. Team also includes integrations, webhooks, and REST API access. The free plan includes 3 team members, 1 project, unlimited guests, and 100 MB of storage. Pro is $19 a month and Team is $39 a month. Review requires a desktop browser window at least 1,024 pixels wide; Wix page passwords do not work for staging review.
Hypothesis
Hypothesis adds shared annotations to digital course materials, letting learners mark passages, ask questions, and reply to peers alongside the content. Users can create private highlights and page notes, add tags, and hold threaded discussions. Supported material includes web pages, PDFs, EPUB files, YouTube videos, and content from VitalSource and JSTOR. For institutional use, Hypothesis lists LTI 1.3 integrations with Canvas, Blackboard, Moodle, D2L Brightspace, and Sakai; annotations can also sync with LMS gradebooks, including Canvas SpeedGrader. A free account is available for personal use and collaboration. The web app works with a Chrome extension on Chrome and other Chromium browsers, or a bookmarklet in Firefox and Safari. Hypothesis also offers API access, exports in JSON, plain text, CSV, and HTML, and JSON import. The Free plan costs nothing, billed per student/yearly, and includes core annotation, private groups, and self-service support. The project was founded as an open-source project in 2011.
