ScreenFeel vs Proton Lumo

Lumo and ScreenFeel want the same thing for you. The difference is simply that Lumo cannot see your screen — you have to describe what you are looking at.

Proton Lumo: A privacy-first AI assistant from Proton, with zero-access encryption and no training on your data. Paid from $12.99/mo — Roughly $9.99/mo effective on an annual plan. Free tier: Yes. Researched in August 2026.

	ScreenFeel	Proton Lumo
Can it see your screen?	Yes — a region, an element, the visible tab, a full scrolling page, or any window on your desktop.	No. It is a text assistant; it cannot capture or read your screen.
Where do captures live?	In your browser, in IndexedDB. There is no server-side gallery to breach, because none was built.	Conversations are stored with zero-access encryption.
What does the AI provider keep?	Nothing. Lenses run on open-weight models under zero data retention, and a build check fails if a configured model is not marked private.	Strong: no training on user data, open source, encrypted at rest.
Annotate and redact before sharing?	Eleven-tool editor. Redaction is flattened into the exported pixels, not a removable overlay.	Not applicable — no capture workflow.
Searchable history of what you captured?	Yes — full-text search across titles, tags and text read out of the images, all local.	Chat history, not a capture library.
Tools for live screen sharing?	Cursor glow, spotlight boxes and arrows drawn locally, plus a warning when your other tab titles are about to be exposed.	None.
Price	€9.99/mo, or a free tier that runs every lens.	$12.99/mo as researched in August 2026.

When Proton Lumo is the better choice

If you want a general-purpose private assistant for writing and thinking — and a wider Proton suite of mail, calendar and drive around it — Lumo is a stronger product for that job. ScreenFeel answers questions about pictures of your screen, and nothing else.

Try it without deciding

Capture, editing, redaction, the library and the presenter tools work with no account at all, and the free plan runs every lens. Nothing here needs a card.
