Annotate.net

Overview

Annotate.net is a teaching and presentation tool built around interactive course materials, student annotations, and instructor feedback. It suits educators who want to combine assignments with discussion and assessment in the material itself. Its strongest case is classroom work with Google Slides, PDFs, and web pages; its account caps and instructor eligibility make it less suitable as a casual, unrestricted presentation tool.

Instructors can build assignments from web pages, PDFs, and Google Slides for Google Classroom, while students annotate those materials and notebooks. Instructors can review submissions in real time and give audio or webcam video feedback. Interactive questions can be embedded in supported content, and the service also includes live polls, quiz activities, audience questions, assessment reports, and LMS integration. For more options in this category, see Interactive Classroom Software.

Key features

• Questions inside course content: Ten interactive question types can be embedded in Google Slides, PDFs, web pages, and Annotate notebooks. That keeps questions alongside the material being taught, rather than making the tool solely a standalone polling service.
• Annotation and feedback: Students can mark up Slides, PDFs, and notebooks; instructors can review work in real time and respond with audio or webcam video. This suits lessons where feedback on a particular passage or page matters more than a simple score.
• Assignments and imports: Assignments can use web pages, PDFs, or Google Slides with Google Classroom. The product tour also describes importing PowerPoint, PDF, and SMART Notebook files, plus files from Dropbox and Box, giving teachers several ways to bring existing materials into a lesson.
• Browser and iPad tools: The Chrome extension supports web-page annotation, text highlighting, and screen-image capture while sharing a screen. The maker says its iPad app combines web-app and Chrome-extension capabilities and works with Adobe PDFs, Google Slides, and Google Classroom.
• Screen sharing and mirroring: The Mirror Client supports screen sharing or remote desktop control, with AirPlay and Google Cast as options. Those capabilities are useful for presenting or demonstrating material, though the free accounts impose daily limits on sharing and mirroring.
• Privacy and security: The privacy policy describes TLS 1.2 protection in transit, encryption at rest, and salted and hashed passwords. The maker says it does not sell or rent personal information or share it with third parties for advertising or marketing. It says the service seeks to comply with COPPA, FERPA, SOPIPA, and CIPA, and is designed to operate in compliance with SOPIPA.
• Support: Starter and Pro student accounts include email support. Tutorials and a bug-report form are also linked from the site.

Pricing

Annotate.net is freemium, with free accounts for students and instructors and annual paid plans. The free tiers can cover a limited class or trial use, but storage, enrollment, sharing time, and notebook privacy differ by account type.

• Student Starter Account — 0.00 USD per free: Includes 100MB storage, one regular enrollment course of up to 50 students, livestreams, audio streams, and screen shares for 2 hours/day, and annotation clips up to 12 minutes. It is a practical starting point for a single small course, but the storage and one-course cap constrain wider use.
• Student Casual Access — 0.00 USD per free: Requires no signup, but is limited to open enrollment assessments. It is the lightest option for students joining those assessments, not a full account for ongoing coursework.
• Educational Instructor Free Account — 0.00 USD per free: Provides 500MB storage and private notebooks, with screen sharing capped at 2 hours/day and mirroring at 15 minutes/day. It is the most useful free tier for eligible educators who need private teaching materials, though the mirroring limit is restrictive for frequent demonstrations.
• Instructor Free Account (non-educational) — 0.00 USD per free: Includes 100MB storage, public notebooks, screen sharing for 2 hours/day, and mirroring for 10 minutes/day. Public notebooks and the lower mirroring allowance make this a narrower fit than the educational free account.
• Student Pro Account — 12.79 USD per year, billed 1 year: The discounted annual price is $12.79, against an original price of $15.99. It raises storage to 5GB and allows unlimited regular and large enrollment courses, while annotation clips remain capped at 12 minutes. It fits students who need more room or multiple courses.
• Educational Instructor Pro Account — 15.99 USD per year, billed 1 year: The discounted annual price is $15.99, against an original price of $19.99. It includes 15GB storage, private notebooks, cloud remote desktop control, shared courses, and screen sharing and mirroring without listed daily limits. This is the clearest upgrade for eligible educators who rely on those tools beyond the free tier’s daily caps.
• Instructor Pro Account (non-educational) — 27.99 USD per year, billed 1 year: The discounted annual price is $27.99, against an original price of $34.99. It includes 15GB storage, private notebooks, cloud remote desktop control, and screen sharing and mirroring without listed daily limits. It suits trainers or presenters outside eligible educational institutions who need the Pro capabilities.

Educational instructor access requires an active instructor at a K-12 or higher education institution, registration with an institutional email, and parental consent arrangements where applicable for students under 13. Instructor access by cell phone is not recommended for daily use; some features may be disabled or may not work as designed.

Platforms

Annotate.net supports Android, iOS, Linux, macOS, the web, and Windows, and offers a browser extension. The iPad app and Chrome extension extend annotation and classroom workflows, while the Mirror Client adds screen sharing and remote desktop options.

Who it's for

Annotate.net is best suited to K-12 and higher-education instructors who want students to work directly on course materials, with trainers and other presenters also within its intended audience. Students benefit when a course uses those assignments and feedback tools. Casual presenters who mainly need quick audience polling may find the course-material and account structure unnecessary; instructors expecting to use a phone as their daily teaching interface should look elsewhere.

Pros and cons

• Pro: Questions, annotations, assignments, and feedback can be tied to Slides, PDFs, web pages, and notebooks, which supports teaching around the actual course material.
• Pro: The eligible educational free account includes private notebooks and 500MB storage, with a paid path to shared courses and no listed daily screen-sharing or mirroring limits.
• Pro: Several import sources and Google Classroom support can accommodate existing teaching materials and classroom workflows.
• Con: Free screen-sharing and mirroring time is capped, and free account storage ranges from 100MB to 500MB, so frequent or resource-heavy use can push users toward Pro.
• Con: Educational instructor access has institutional eligibility and email requirements, limiting its fit for independent educators who do not qualify.
• Con: Cell-phone instructor access is not recommended for daily use, weakening the case for teachers who need a dependable phone-first workflow.

Alternatives

Choose Poll Everywhere instead if you want a freemium audience-response tool with a free Intro plan capped at 40 people (or 700 for 30 days) and 10 AI prompts per month; Annotate.net is more centered on annotation and course assignments.

Wayground (formerly Quizizz) may suit readers who want a free Starter plan with up to 100 participants per session, while its 20-activity limit and limited library access shape the free tier. Annotate.net is the stronger fit when students need to mark up course content and receive instructor feedback.

Pick Kahoot! for a free classic live quiz experience with up to 40 participants and quiz or true/false questions. Annotate.net puts more emphasis on annotations, assignments, and feedback.

AhaSlides is an alternative for presentation-led interaction: its free plan allows up to 50 participants, five quiz questions, three poll questions, and unlimited presentations per month. Annotate.net is better aligned with annotated teaching materials and classroom work.

Choose Socrative if its free plan’s five quizzes, one room, 50 students per activity, and 30-day report history match your assessment needs. Annotate.net combines assessment with annotation and feedback on course content.

ClassPoint is another option for readers comparing classroom interaction software.

Mentimeter is another option for readers comparing classroom interaction software.

Slido is another option for readers comparing classroom interaction software.

Verdict

Choose Annotate.net if you teach with PDFs, Google Slides, or web pages and want questions, student markup, assignments, and feedback to stay connected to that material. Its educational free account offers a useful starting point, and Pro removes the listed daily sharing and mirroring limits. Look elsewhere if you need phone-first instructor access, do not meet educational eligibility, or mainly want a straightforward live-polling tool.
