How it works

Bring your own Finnish.
We do the rest.

Tell us about yourself

Quick onboarding — your current level, exam date if you have one, biggest challenge. Takes 60 seconds. Sets everything up for you.

Paste any Finnish text

A page from Suomi Mestari, a work email, your rental contract, a government letter. Paste it and hit generate. Every grammar pattern is identified and colour-coded instantly.

Hover, select, and go deep

Hover any highlighted word for an instant explanation. Select any phrase and open a chat thread anchored to that exact phrase. Ask anything — why is this in partitive? How would I say this differently?

Save words, come back tomorrow

One tap to save any word. Kielio generates all 15+ inflected forms automatically. Review your personal vocabulary bank with the original sentence always visible.

Why Kielio is different

Your content.
Not ours.

Kielio works with the Finnish you actually encounter every day — Suomi Mestari pages, work emails, rental contracts, government letters — plus weekly lessons from Finnish legal and government texts.
