Part 1. Why Need a Kami Alternative

Subscription economics push teachers off Kami

Kami was known for its generous free tier, but per-seat licensing and tightening budgets have led many districts to cut subscriptions --- sometimes with only a week's notice before the semester. Teachers are scrambling to find replacements before the next assignment cycle. You can see teachers asking in forums, in faculty chats, on r/Teachers about which apps like Kami they should adopt before the next assignment cycle.

Google Drive sits at the center of K-12 workflows

Every tool here supports Google Drive, because that's where K-12 work happens --- assignments, submissions, rubrics, and permission slips. Any Kami replacement must plug into Drive without downloads, installs, or a new storage paradigm.

Annotation alone is not enough --- Google Docs matter

Kami handled both PDF annotation and Google Docs markup. Most alternatives only do PDFs. If you assign reading responses, peer reviews, or comment-heavy Docs work, you need both. Only one mainstream option annotates Docs and PDF in the same sidebar; everyone else forces a tool switch.

Student-side zero install is non-negotiable

If students must install an extension, create an account, or download a client, adoption drops fast. Link-based tools --- click, annotate, submit --- get used; setup-heavy tools get abandoned. Every tool below was tested on both sides.

Every tool below was tested on both sides of that workflow.

Part 2. How We Tested Kami Alternatives

We scored each of the 10 tools across six dimensions. None of these dimensions is a deal-breaker on its own, but the combination shapes which tool fits which classroom.

• Dimension 1 --- Google Drive integration depth. Three tiers matter here. Drive "Open with" lets you right-click a PDF in Drive and open it in the tool without installing anything. Chrome Extension adds a one-click button inside the browser. Drive Add-on embeds the tool inside the Drive sidebar so you never leave the Drive page. The deeper the integration, the less friction for teachers and students.
• Dimension 2 --- PDF annotation tools. Highlighting, text boxes, freehand drawing, stamps, signatures, and form filling. We checked whether the free tier covered each tool or gated it behind a paywall.
• Dimension 3 --- Google Docs annotation. This is the make-or-break dimension for K-12. If a tool can't annotate a Google Doc, it isn't a real Kami replacement for most teachers --- it's a PDF-only substitute.
• Dimension 4 --- Pricing model. Free tier, freemium, per-seat subscription, or one-time buyout. We tracked what the free tier actually includes, not what the marketing page claims.
• Dimension 5 --- Student-side experience. Can a student complete and submit work without installing anything? Can a teacher distribute work via a single link? Is submission tracking visible to the teacher?
• Dimension 6 --- Privacy and data flow. Where do student files go after upload? Are they processed locally on a desktop app, in a browser sandbox, or in a vendor's cloud? FERPA matters here, and teachers should know which category each tool falls into.

Who Should Pick What

Different classrooms need different tools. Here's the decision matrix:

• District IT blocks Chrome extensions → Drive "Open with" tier: Xodo, iLovePDF, Smallpdf, Lumin, Sejda, Web Highlights
• Teacher wants to install one extension and go → Chrome Extension tier: Xodo, DocHub, Smallpdf, iLovePDF, pdfFiller, Adobe
• Teacher wants to stay inside Drive for both Docs and PDF → Drive Add-on tier: DocHub, pdfFiller, Lumin
• Teacher workflow is mostly forms + signatures + collection → pdfFiller, Lumin
• Teacher wants offline annotation + Cloud Share distribution, no subscription → PDNob PDF Editor (differentiator: AI translation + OCR included)
• District has budget and wants brand-name security → Adobe Acrobat
• Teacher only needs browser-based highlighting + notes → Web Highlights
• Bilingual classroom or ESL support → PDNob PDF Editor (side-by-side AI translation is the standout)

Part 4. Details of Top 10 Apps Like Kami

4.1 Web Highlights · Chrome-Native Lightweight Annotator

When I opened Web Highlights for the first time, what struck me was how minimal the chrome actually is. There's no app to launch --- you click the extension icon while reading a PDF in your browser, and the sidebar wakes up. For teachers who mostly highlight and extract, this is the lightest possible workflow.

Web Highlights started as a web-article annotation tool and expanded into PDF support. The Chrome extension is the primary surface; there is no standalone desktop app and no mobile build. The "Open with" tier is covered because any open PDF tab in Chrome can be annotated.

Supported Devices / Ecosystem: Chrome extension only --- runs on any Chrome browser (Win / Mac / Linux / Chromebook), no native mobile build

Note:

Its' Annotation tools are limited to highlights, text notes, and the sidebar tag system --- no form filling, no signatures, no OCR. That's a feature gap for teachers who need to sign permission slips, but it's also the reason Web Highlights loads instantly and never feels heavy.

4.2 Xodo PDF Editor · Cross-Platform Free PDF Editor

Xodo is what you get when a free PDF editor tries to do everything. Web, desktop, mobile, Chrome extension --- all from the same account, with annotations syncing across surfaces. For teachers who switch between an iPad at school, a laptop at home, and a phone in between, that's the killer feature.

Xodo's Chrome extension opens Drive PDFs without downloading, and the Drive "Open with" route works for anyone who doesn't want to install anything. The annotation toolkit is broad: highlight, draw, fill forms, sign, merge, split. The free tier covers the everyday stuff; OCR and redaction sit behind the paid plan.

Supported Devices / Ecosystem: Web · Windows · macOS · iOS · Android · Chrome Ext (6 surfaces, broadest mobile coverage)

My Take:

Xodo is the closest thing to a "does everything free" Kami replacement --- annotation, forms, signatures, sync across devices, with no subscription gating the everyday toolkit.

4.3 pdfFiller · Drive-Embedded Forms Workflow

Pdf filler is a forms-first tool with annotation grafted on. If your teacher's workflow is "send a permission slip, collect signed copies, file them," pdfFiller is more useful than a general annotator. If your workflow is "annotate reading assignments," pdfFiller feels heavy.

The Drive Add-on is the standout. Embed it in Drive's sidebar and form filling, signing, and submission tracking happen without leaving the Drive page. Chrome extension adds a one-click path for PDFs that aren't already form-ified. The free tier caps form submissions, which is the real constraint for classroom use.

Supported Devices / Ecosystem: Web · iOS · Android · Chrome Ext · Drive Add-on (no desktop native)

Tested Words:

pdfFiller isn't trying to be Kami --- it's built around forms and signatures first, with annotation grafted on. If your workflow is permission slips and consent forms, this is the right shape.

4.4 DocHub · One-Stop Doc + PDF + Form Annotator

DocHub is the only mainstream tool on this list that annotates Google Docs and PDF in the same sidebar. That's the whole reason it's here. If you assign Doc-based reading responses and PDF-based worksheets in the same week, DocHub is the tool that handles both without forcing a workflow switch.

The Drive Add-on is the primary surface --- embed it and Doc + PDF annotation both appear in the Drive sidebar. The Chrome extension adds a one-click path when you're working outside Drive. Form filling, signatures, and a library of common school paperwork (permission slips, rubrics) round out the package.

Supported Devices / Ecosystem: Web · iOS · Android · Chrome Ext · Drive Add-on (no desktop native)

One caveat:

DocHub is the only tool on this list with a Google Workspace Add-on that natively edits both PDF and DOCX (Google Docs format). pdfFiller has a similar Add-on, but its workflow converts the Google Doc to PDF before editing — losing the live DOCX format. Lumin and Sejda integrate via Google Drive 'Open with' but don't annotate native Google Docs files.

4.5 Smallpdf · Trusted Brand for Daily PDF Tasks

Smallpdf is the brand students and parents already know. The interface is clean, the tools are obvious, and the Chrome extension works the way you'd expect. For teachers who don't want to learn a new interface and parents who might need to use the same tool at home, that brand familiarity matters.

The free tier is more limited than Xodo's --- most tools cap at two tasks per day before the paywall appears. The Chrome extension handles Drive-resident PDFs; there is no Drive Add-on. Smallpdf is a solid "everyday PDF tool" rather than a teacher-specific platform.

Supported Devices / Ecosystem: Web · Windows · macOS · iOS · Android · Chrome Ext (full coverage, no Linux)

Why we Recommend it:

Smallpdf is the brand students and parents already recognize. The interface is the most beginner-friendly on the list, and the trade-off is a tighter free tier than Xodo or iLovePDF.

4.6 iLovePDF · Free + Chinese-Friendly PDF Tool

iLovePDF is the closest thing to Smallpdf's alternative --- same general toolkit, similar interface, but with a more generous free tier and a Chinese UI out of the box. For teachers in bilingual programs, or for districts with non-English-speaking staff, the language support is the real differentiator.

The Chrome extension integrates with Drive; the free tier covers annotation, conversion, merging, and basic OCR. Advanced features (batch OCR, redaction) are paywalled. There's no Drive Add-on.

Supported Devices / Ecosystem: Web · Windows · macOS · Linux · iOS · Android · Chrome Ext (7 surfaces, widest coverage on this list)

The verdict:

iLovePDF is the Smallpdf alternative that wins on free-tier generosity and Chinese-language support. For non-English-speaking teachers or districts, that language support matters more than the brand.

4.7 Lumin · Drive-Native Annotation + Form Collection

Lumin is built for the teacher workflow --- annotate, assign, collect --- and the Drive Add-on makes that workflow feel native to Drive rather than bolted on. If your classroom runs on assignment distribution and submission tracking, Lumin is purpose-built for it.

The Drive Add-on and Chrome extension both work. The free tier covers annotation and signature, but document volume is limited --- heavy users hit the cap fast. OCR isn't in the free tier. Mobile is a thin wrapper around the web app.

Supported Devices / Ecosystem: Web · iOS · Android · Chrome Ext · Drive Add-on (mobile-friendly but no desktop native)

Where it wins over Kami:

Lumin is purpose-built for the assignment-distribution-and-collection workflow. The Drive Add-on is the primary surface, and the form tracking dashboard is the part teachers actually use day to day.

4.8 Sejda · Heavy-Duty Free PDF Operations

Sejda gives you a generous free tier --- for occasional use. The daily task quota is the constraint, not the feature set. Heavy classroom use will hit the cap fast. If you're a teacher who uses a PDF tool three times a week, Sejda is excellent. If you're a teacher who annotates 30 worksheets a day, Sejda will run out by Wednesday.

Sejda offers web, desktop, Chrome extension, and Drive Add-on surfaces. The annotation toolkit covers the basics plus OCR and form editing. The interface is functional, less polished than Smallpdf or Xodo.

Supported Devices / Ecosystem: Web · Windows · macOS · Linux · Chrome Ext · Drive Add-on (no mobile)

Why we bet on it:

Sejda's free tier is the deepest on the list --- OCR, form editing, advanced PDF edits, all without paying. The catch is the daily task quota, which disappears by Wednesday for heavy classroom use.

4.9 PDNob PDF Editor · Desktop + Cloud with AI Translation & OCR

PDF annotation featuresThat trade-off matters. Chrome-extension-and-Drive-Add-on tools feel lighter because there's nothing to install. PDNob PDF Editor is a desktop-first PDF tool that handles annotation, OCR, AI bilingual view translation, and Cloud Share distribution. PDNob ships the same Kami had --- highlight, draw, stamp, sign --- and layers OCR on top, so scanned worksheets and student phone-captured homework become markable instead of static images. It's also a backup solution when teachers get offline annotation power, students get a frictionless browser experience. For IT-restricted districts that block extensions but allow desktop apps, this is the path that actually works.

Supported Devices / Ecosystem: Windows · macOS (desktop app); Cloud Share opens in any browser; Online version allows google drive upload

Two features keep PDNob on the shortlist :

• AI bilingual side-by-side translation with 40+ languages on the Gemini-3-flash model. The Pro version is unlimited. Real differentiator for bilingual and ESL classrooms.
• OCR that handles scanned worksheets and handwritten phone captures. Kami never had strong OCR, and most alternatives here charge extra for it.

Field notes:

What I noticed after a week with PDNob is that the workflow is genuinely different from the rest of the list. There's no Chrome extension to install and no Drive Add-on to enable. Instead, you launch the desktop app, open a PDF from anywhere on your machine (or pull it from Google Drive via Cloud Import), annotate locally, and share via a Cloud Share link. The student opens the link in any browser --- no client, no extension, no account.

4.10 Adobe Acrobat · Professional PDF Ecosystem

Adobe is the safe choice when the district already has Adobe volume licensing or when "PDF tool" must mean "the one with every feature ever shipped." The full Acrobat covers annotate, fill, sign, OCR, redact, batch --- everything. Drive Add-on, Chrome extension, and desktop are all there.

The trade-off is price. Acrobat is subscription-only, and the per-seat cost adds up across a faculty. The free tier (Acrobat Reader) doesn't include full annotation, so teachers who want real editing need to pay. Adobe also feels heavier than competitors on older school hardware.

Supported Devices / Ecosystem: Web · Windows · macOS · iOS · Android · Chrome Ext · Drive Add-on (full ecosystem)

Why It's Listed:

Adobe Acrobat is the safe pick when the district already has volume licensing or when "PDF tool" has to mean "everything ever shipped." The price is the highest on the list, and the brand is the strongest.

Part 5. Tips on Transferring Work from Kami

Tip 1 --- Audit What You Actually Use in Kami

Before switching, list what you actually do in Kami day to day: annotate PDFs, fill forms, share links, comment on Google Docs, collaborate with co-teachers. Mark which are core (must-keep in the new tool) and which are nice-to-have. Most teachers discover they use 30% of Kami's feature set --- which means most tools on this list will cover their actual workflow.

Tip 2 --- Pick by Priority

Three priorities cover most teacher workflows:

• Google Docs annotation is the hardest to replace --- only DocHub handles it in the same sidebar as PDF. If you assign Doc-based reading responses, this is your top filter.
• Student-side zero install is the second filter --- Web tools, Chrome extensions, and Cloud Share links all satisfy it. Anything that requires a student-side client install will hurt adoption.
• Price is the third filter --- free tiers (Xodo, Sejda, Lumin) cover most needs, but a one-time $64.99 PDNob license often beats multi-year subscription math.

Tip 3 --- Migrate Files Without Losing Annotations

Kami exports PDFs with the annotation layer preserved. The migration itself is a four-step process:

• Step 1. Export each Kami-annotated PDF to your local machine or Drive.

• Step 2. Open the exported PDF in your new tool --- most tools on this list open a PDF file directly, including PDNob's desktop app.

• Step 3. Confirm the annotation layer survived export. If annotations appear flattened (turned into image content), the new tool will only see a static PDF. If they appear as a separate layer, you can continue editing.

• Step 4. Re-share via the new tool's distribution mechanism. For PDNob, that's Cloud Share --- upload, set access code if needed, copy the link, send to students.

Google Docs are trickier. Most alternative tools don't annotate Google Docs natively. Two paths: use DocHub for Doc-based work, or use Google Docs' built-in Suggesting mode as a no-cost fallback.

Tip 4 --- Pilot Before You Commit

Don't switch your entire classroom on day one. Pick one class or one assignment type and run it through the new tool for a week. Watch for three things:

• Student-side friction --- does the link open cleanly, does the student need to sign up, does submission work?
• Teacher-side friction --- does annotation feel natural, do forms route correctly, does the tool play nice with your existing Drive organization?
• Data flow --- where do student files end up after submission? Local on the teacher's machine, vendor cloud, or somewhere in between?

If all three check out after a week, scale up. If any of them break, you've learned cheaply and can try the next tool on your shortlist.

Conclusion

There's no single kami alternative that covers every teacher workflow perfectly --- but the 10 tools on this list cover every combination of Drive integration tier, annotation depth, and pricing model. The right pick depends on your school's IT constraints, your students' device situation, and how much Google Docs work your assignments include. Pick the tool that fits your answers, run a one-week pilot, and commit.
