Comparison

Proton's Lumo can read your Drive. Archevi answers and shows you the source.

In June 2026 Proton added Lumo, an AI assistant that works with your Drive files, which closes the old gap where Proton only stored documents. Two things still separate them for a Canadian family. Archevi cites the exact document and page behind every answer, and it strips personal details inside Canada before any AI reads a file. Proton Family includes Lumo, but on its metered free tier.

Heads up: Proton Family includes Lumo on its free tier

Proton Family now bundles Lumo, so it can answer questions about your Drive files. On the family plan that is Lumo's free tier, with limited usage. Unlimited questions need a paid Lumo upgrade on top of the family plan.

Archevi includes document Q&A on every plan with no separate AI add-on, and every answer links to the exact page it came from.

Where Archevi and Proton Lumo differ

Answers that cite their source

Ask "when does our home insurance expire?" and Archevi answers with the exact document and page cited. A general assistant gives you a written answer and asks you to trust it. Archevi shows you where the answer came from so you can check it yourself.

Private before the AI reads it

Proton's encryption protects your files in storage and in transit. The moment you ask Lumo a question, the model still reads the real contents. Archevi replaces names, SINs, and account numbers with stand-ins before any query reaches the AI, so your identifiers are never in the model's view.

Canadian data residency (PIPEDA)

Lumo is built and hosted in Europe under European privacy law. For Canadian families, Archevi's Toronto hosting under PIPEDA removes the cross-border question for your medical and legal documents.

Built for living documents

Wills, insurance, tax slips, and medical records, with expiry tracking and a family timeline. Lumo's Projects are general-purpose workspaces. Archevi is shaped around the documents a household actually uses.

Two private products, built for different jobs

Proton built one of the most respected encrypted suites in consumer software, and in 2026 it added Lumo, an AI assistant that can now work with the files in your Drive. That is a real step. For households that want encrypted storage with a capable assistant on top, Proton is a strong choice.

The interesting question is no longer whether Proton has AI. It does. The question is what happens at the moment you ask it something. With Lumo, the model reads your decrypted files and writes you an answer. With Archevi, the model reads an anonymized copy with names and numbers removed, and the answer comes back with the exact source passage attached.

Archevi takes a Canadian position. Files live in Toronto under PIPEDA. Personal details are stripped before any query touches the language model, so your raw identifiers never enter the model's context, and every answer cites the document and page it came from.

These can be complementary. Proton handles encryption, email, VPN, and general storage with an assistant attached. Archevi sits on the documents you most need to ask questions about and answers with a citation. Some privacy-conscious Canadian families will use both.

On price, Proton Family is around €23.99 a month for the full encrypted suite with Lumo on its free tier. Archevi starts at $6 CAD a month with document Q&A included on every plan and no separate AI add-on. Which one fits depends on the problem you are solving: a full encrypted suite, or a family vault that answers questions about your documents with the source attached.

What Proton does better, and we'll say so

Proton's encrypted suite is genuinely excellent. Mail, VPN, Pass, Calendar, and Drive are polished and deeply integrated, and Lumo adds a capable assistant across them. If you want one privacy-focused vendor for your whole digital life, Proton is a strong answer, and we don't try to compete on those surfaces.

Proton's zero-access encryption is also a stronger guarantee than ours for files you only ever store and never query. The keys live with you, and even Proton cannot read those file contents. For documents you never need to ask about, that is a meaningful difference.

Archevi earns its place when you want every family member to ask questions about your documents and get an answer with the source attached, and when Canadian jurisdiction matters more to you than European. On that job, the cited answer and the redaction step are the difference.

Use Proton for your encrypted suite. Use Archevi for cited answers.

Start on the Core plan for $6 CAD a month. Every family member gets document Q&A with the source cited, personal details stripped before the AI, and hosting in Canada.
