Proton Docs vs Google Docs: Which Document Editor Should You Trust?

If you want the most capable document editor, Google Docs still wins. If you want a document editor that cannot read what you write, Proton Docs is the only mainstream option. That single trade-off — capability versus privacy — decides this entire comparison, and it is sharper than most head-to-heads because the two products are not really trying to be the same thing.

Proton Docs, launched inside Proton Drive in July 2024, is a deliberately lean editor wrapped in end-to-end encryption: your document names, content, edits, comments, and even keystrokes and cursor movements are encrypted so that not even Proton can read them. Google Docs is the opposite bet: a mature, deeply integrated editor that trades that privacy for Gemini AI, offline editing, templates, and an ecosystem nothing else matches. I verified every price, plan limit, and feature claim in this article against the official Proton and Google pages on October 30, 2026, and I flag the two places where hands-on testing was not possible without a signed-in account.

What Is Proton Docs, and How Is It Different From Google Docs?

Proton Docs is the document editor inside Proton Drive, Proton’s encrypted cloud storage. You open it from drive.proton.me, and it works in the browser and through the Proton Drive apps on desktop and mobile. It covers the core job well: formatted text, headings, lists, tables, images, links, comments, and suggesting mode, with real-time collaboration that shows edits as they happen and live cursors for other viewers.

Google Docs is the document editor inside Google Drive, and it has had nearly two decades to accumulate features: a large template gallery, voice typing, offline editing through Chrome, version history, add-ons, and Gemini AI built into the editor for drafting, rewriting, and summarizing. It also sits inside the largest productivity ecosystem on the web — Sheets, Slides, Drive, Gmail, and Meet share the same account and storage.

The honest framing is this: Proton Docs is a word processor with privacy as its headline feature. Google Docs is a word processor with everything else as its headline feature. Which one you should pick depends on which sentence matters more to you.

How Do Proton Docs and Google Docs Compare on Privacy and Encryption?

This is the category Proton Docs wins outright, and it is not close. Proton Docs applies end-to-end encryption to the whole document: content, file names, comments, suggestions, and even keystrokes and cursor movements during live collaboration. Proton’s own comparison page states the point plainly — with Google Docs, Google can access your documents, while with Proton Docs, only you and the people you share with can. Proton is also based in Switzerland, under Swiss privacy law, outside both EU and US jurisdiction.

Google Docs encrypts your documents in transit and at rest on Google’s servers, but Google holds the keys, so the company can access content for abuse detection and legal requests. Client-side encryption — where even Google cannot read a document — exists, but only on paid Google Workspace plans, not on the consumer Google Docs most people use. Google also trains no Gemini model on your personal Docs content by default, but your documents still live in a system designed to be readable by its operator.

One practical consequence: sharing works differently. Proton Docs lets you share encrypted links and revoke access at any time, and you can set passwords and expiration dates on shared files through Proton Drive. Google Docs sharing is more flexible — anyone-with-the-link, domain-restricted, commenter versus viewer roles — but every shared document remains readable by Google’s infrastructure.

Proton Docs vs Google Docs: Side-by-Side Comparison

Which Is Better for Real-Time Collaboration?

Google Docs, by a clear margin — with one caveat that matters. Google’s collaboration is the industry reference: simultaneous editing, comment threads you can assign and resolve, suggested edits, version history you can restore by the minute, and the ability to start a Meet call from inside the document. If your team edits together every day, nothing else feels as smooth.

Proton Docs covers the essentials — real-time edits, live cursors, comments, and suggesting mode — and that is genuinely impressive for an encrypted editor, because encrypting live keystrokes is a hard problem. But it is younger and narrower: no comment assignments, no built-in video calls, no add-on marketplace, and no equivalent of Google’s version-history depth. The caveat: Proton’s collaboration is encrypted end to end, so collaborators’ edits are private from Proton itself. Google’s collaboration is better, but it is not private in the same sense.

What Does Each Cost?

Both editors are included in their parent storage plans at no extra charge, so the real price comparison is the storage plan behind them. Proton’s no-cost plan includes 5 GB of Drive storage with the Docs editor and full end-to-end encryption — the same encryption paying customers get. Drive Plus raises that to 200 GB at $3.99 per month billed annually, with 10 years of file-version recovery, and Proton Unlimited bundles 500 GB with Mail, Calendar, VPN, and Pass at $9.99 per month billed annually.

Google’s no-cost plan is more generous on raw storage: 15 GB shared across Drive, Gmail, and Photos, with Docs included. Google One Basic adds up to 100 GB for $1.99 per month, and Premium gives 2 TB for $9.99 per month. The AI gap costs extra on both sides: Gemini inside Docs requires Google AI Pro at $19.99 per month, while Proton has no AI inside Docs at any price — its Lumo assistant is a separate product.

The trap to avoid: comparing only the headline storage numbers. Proton’s 200 GB plan costs about the same as Google’s 100 GB plan, but you are paying Proton for encryption, not gigabytes. If storage per dollar is your metric, Google wins. If encryption per dollar is your metric, Proton wins.

Where Does Google Docs Still Win?

Three places, and they are all practical rather than philosophical. First, offline editing: Google Docs works on a plane through Chrome, while Proton Docs needs a connection — if you write on trains, planes, or patchy hotel Wi-Fi, that alone can settle the decision. Second, AI: Gemini drafts, rewrites, and summarizes inside Google Docs, and it is genuinely useful for first drafts and long-document summaries. Proton Docs has no AI inside the editor, by design. Third, breadth: templates, voice typing, add-ons, and the Sheets and Slides companions make Google Docs a complete office, while Proton Docs is a focused editor with a spreadsheet sibling and no presentation tool at all.

There is also a quieter Google advantage: familiarity. Almost everyone you share a document with already has a Google account, and Google Docs links just work for them. Proton Docs links work for anyone too, but recipients who have never heard of Proton may hesitate at an unfamiliar sharing screen — a small friction that matters when you collaborate with clients rather than colleagues.

Can I Move Documents Between Proton Docs and Google Docs?

Yes, and the path is the humble .docx file. Proton Docs uploads and edits existing .docx files and exports to .docx, .pdf, .txt, .md, and .html. So the practical migration is: export from Google Docs as .docx, upload it to Proton Drive, and open it in Proton Docs — or reverse the trip to leave. Expect minor formatting cleanup on complex documents either way, the same way any Word-to-Docs round trip behaves; simple documents with headings, lists, tables, and images survive cleanly.

Two warnings from the fine print. First, the moment you download a Proton Doc, it is no longer encrypted — the protection lives inside Proton Drive, not in the exported file. Second, Proton Docs has no bulk migration tool, so moving a large archive is a file-by-file job. If you are switching teams rather than documents, plan for that afternoon of exporting.

Who Should Choose Which?

Choose Proton Docs if you write anything you would not want a provider to read: legal drafts, medical notes, investigative reporting, unreleased business plans, or personal journals. Choose it too if you are already in Proton’s ecosystem — the same account that holds your mail, calendar, and VPN also holds your documents, and the Drive Plus plan that unlocks 200 GB also unlocks the full editor. Our earlier head-to-heads on Proton Drive vs Google Drive and Proton Mail vs Tuta reach the same conclusion from the storage and email angles: Proton is the pick when privacy is the requirement, not the preference.

Choose Google Docs if you collaborate daily, write offline, want AI help inside the editor, or need templates and add-ons to move fast. Students, teachers, and teams already on Google Workspace will lose more than they gain by switching. And if your documents are mostly public-facing — blog drafts, lesson plans, meeting notes — Google’s convenience advantage is real and the privacy cost is low.

The split verdict, then: Google Docs is the better document editor; Proton Docs is the better vault for documents. If you only get one editor, pick the one that matches your most sensitive document, not your most common one — and remember you can use both, keeping everyday writing in Google Docs and sensitive work in Proton Docs, since both have no-cost plans. For the spreadsheet side of the same decision, see our Google Sheets vs Excel comparison.

Method note: prices, plan limits, and feature claims in this article were verified against Proton’s and Google’s official pages on October 30, 2026. Proton Docs’ interface claims follow Proton’s own product pages, since testing live collaborative editing requires a signed-in Proton account; no live editing session was run for this comparison.
