Kami Review (2026): Pricing, Features & Honest Verdict

TLDR

Kami is a browser-based document annotation tool built for classrooms, letting teachers and students mark up PDFs and collaborate in real time. We dug into it and found the most polished option in edtech annotation, with a free plan that does real work. Best for: K-12 teachers. Price: Free plan: yes, Teacher $149/yr. Rating: 7.4/10.

What is Kami?

Kami is a web app that turns any PDF, document, or worksheet into something students can annotate, type on, draw over, and submit. Teachers send a document through the LMS, students mark it up in the browser, and feedback flows back without anyone printing a page. The whole pitch is paperless classrooms that still feel like working on paper. It runs entirely in the browser, so there is nothing to install and it works the same on a school Chromebook as on a teacher’s laptop.

The company behind Kami is based in Auckland, New Zealand, and the product has grown into one of the most widely used classroom tools, claiming tens of millions of teachers and students worldwide. It started as a simple PDF annotator and steadily added the classroom-specific layer that defines it today. It matters now because schools standardized on Google Classroom and Canvas during the remote-learning years, and Kami slots directly into those systems instead of asking teachers to learn yet another platform. When the workflow you already use is the thing being extended, adoption friction drops to almost nothing, which is exactly why Kami spread the way it did.

What Are Kami’s Key Features?

Document annotation and markup

The core of Kami is a layer of annotation tools that sit on top of any document: highlighting, text boxes, freehand drawing, shapes, sticky notes, and signatures. Teachers can mark up student work and students can complete worksheets directly in the browser, typing answers into fields or drawing diagrams by hand. The free Basic plan ships 10+ of these tools, which covers everyday tasks like highlighting a reading and adding margin comments. The full set of 40+ tools unlocks on paid plans and adds things like equation support, more shape options, and richer media insertion.

Real-time collaboration

Multiple people can work on the same document at once, with unlimited collaborators even on the free plan. That makes it usable for group assignments and live feedback sessions, where a teacher can annotate a student’s work while they watch and respond. It behaves like Google Docs comments but for any PDF, not just native Google files, which is the part generic editors can’t match. For small-group work, several students can build out a shared worksheet together without emailing versions back and forth.

LMS integrations

Kami connects to Google Classroom, Canvas, Schoology, Microsoft Teams, and D2L Brightspace, plus Google Drive and OneDrive for storage. Assignments push out and graded work pulls back without manual file shuffling, and grades can sync to the gradebook depending on the integration. This integration depth is the single biggest reason schools pick Kami over a generic PDF editor. A teacher can assign, collect, annotate, and return work without ever leaving the LMS they already plan their day around.

Feedback and accessibility tools

Beyond text comments, Kami supports audio and video feedback recorded straight onto the document, which is faster and warmer than typing for many teachers. It adds translation in 100+ languages plus read-aloud and accessibility scaffolding through its Companion toolbar, which can layer support onto web-based resources too. For language learners and special-education contexts, these tools are the differentiator rather than a checkbox, and they are a big part of why districts justify the spend.

How Much Does Kami Cost?

Kami starts free. The Basic education plan is permanently free, not a trial, and includes 10+ core tools, Google Drive and OneDrive integration, 1,000+ templates, and unlimited collaborators. That is genuinely enough for a lot of teachers to never pay, especially if your needs are highlighting, commenting, and basic worksheet completion.

The individual Teacher plan is $149/year and unlocks all 40+ tools, the full set of LMS integrations, free onboarding, and priority support. On the workplace side, for non-education users, the Pro plan runs $12/month or $85/year and the Work plan is $25/month or $220/year, the latter adding a dedicated account manager and features like Bates numbering. School and District pricing is custom and adds domain-wide deployment, a dedicated account manager, and training, which is how most large rollouts actually buy.

Compared to peers, the math favors Kami for teachers. Lumin handles general PDF editing from around $9/month but lacks the classroom layer entirely, while Turnitin’s Feedback Studio leans on grading and plagiarism checks at enterprise prices negotiated per institution. A flat $149/year for one teacher undercuts most per-seat edtech licensing, and the free tier means you can prove the workflow before anyone signs a purchase order. New teacher accounts also get a 30-day Teacher trial to test the paid features first.

Who is Kami Best For?

Use Kami if you are a K-12 teacher who already lives in Google Classroom or Canvas and wants students annotating, completing, and submitting documents without printing. The free plan is a genuine starting point, and the Teacher upgrade pays for itself in saved prep time. It is also a strong fit for language-learner support and special education, where the translation and read-aloud tools do real work that generic editors can’t.

Skip Kami if you teach math-heavy subjects that need a compass, protractor, or robust equation tools, since those are weak or missing and teachers have flagged the gap. Skip it too if you need a rock-solid offline or mobile-first editor, because the mobile experience is limited and annotations don’t always sync or save reliably, which is the most common complaint in user reviews. If your materials are already native Google Docs, you may not need Kami’s PDF layer at all.

• Great fit: K-12 classrooms, language-learner support, special education, paperless assignment workflows inside an existing LMS.
• Poor fit: advanced math instruction, heavy mobile use, and anyone outside education paying full Workplace rates for basic markup.

One practical note: because Kami lives inside the LMS, its value compounds the more your school standardizes on it. A single teacher can run the free plan happily, but the bigger payoff comes when a whole department or district adopts it and the assign-collect-annotate-return loop becomes the default. That is also where the custom School and District pricing starts to make sense over individual Teacher licenses.

Best Kami Alternatives

Lumin

Lumin is a cloud PDF editor with annotation and e-signature, starting around $9/month. It is cheaper than Kami’s Teacher plan on a monthly basis and stronger as a general-purpose PDF tool, with solid editing and form-filling. But it lacks the deep Google Classroom and Canvas hooks, so it is a worse fit for actual classroom assignment flows where you need to assign, collect, and return work inside the LMS. Pick Lumin when you want a personal PDF editor, not a teaching platform.

Turnitin Feedback Studio

Turnitin’s Feedback Studio is the heavyweight for grading and originality checking, used widely in higher ed. It excels at rubric grading, similarity reports, and plagiarism detection that Kami doesn’t attempt. Pricing is institution-level and negotiated, typically far above Kami. Pick it when academic integrity and structured grading matter more than lightweight document markup, and when a department or university is footing the bill.

Google Workspace comments

If your school already runs Google Workspace, Docs and Slides comments are free and handle basic feedback inline. They cannot annotate arbitrary PDFs or worksheets the way Kami can, and there is no drawing or audio feedback on a scanned document. This only works as a Kami replacement when your materials are already native Google files, but for those cases it costs nothing and everyone already knows how to use it.

Final Verdict: Is Kami Worth It?

Kami earns its place as the default annotation layer for classrooms. The free Basic plan does real work rather than acting as a teaser, the LMS integrations are genuinely deep, and $149/year for the full Teacher unlock is fair next to per-seat competitors. For its core audience of K-12 teachers running paperless assignments, it is an easy recommendation, and the accessibility tooling makes it stand out for diverse classrooms.

The 7.4 reflects real friction we can’t ignore: annotations that occasionally fail to save and force a redo, thin math tooling that frustrates STEM teachers, and a limited mobile app. None of that is a dealbreaker for a Google Classroom teacher working on a laptop, but together they stop Kami short of top marks. The competition tells the story too: a general PDF editor like Lumin is cheaper but doesn’t understand classrooms, and Turnitin is far pricier and aimed at a different problem, which leaves Kami sitting in a sweet spot for everyday K-12 annotation. Start on the free plan, confirm the save behavior holds up in your specific workflow, and then upgrade to Teacher once you know it sticks. For most teachers who already plan inside Google Classroom or Canvas, that path leads to a yes.
