About Katafera

What it is

Katafera is a grammar-first Modern Greek course. It teaches the rules explicitly - gender and the article, the four cases, how verbs conjugate - and then drills them, so that you understand why a word takes the form it does instead of only recognising phrases.

Its grammar reference is the course's back matter, open to everyone: 125 entries in 6 categories, covering A1–B2, each with the rule, the full tables, and examples.

It is built and run by a single independent developer who is learning Greek too. There is no company behind it. The name is κατάφερα (katáfera), Greek for “I managed it”.

How the grammar is checked

Modern Greek only, in the monotonic spelling Greece has used since 1982: one accent mark, the tonos, plus the dieresis. No Ancient Greek and no polytonic forms.

Every table is generated from a single forms database rather than typed into the page. Those forms were checked against published sources - chiefly Wiktionary's Modern Greek inflection tables - and the hard cases, stress shifts above all, against a second one. Because the tables share one source, a correction made once reaches every table that shows that form.

Each Greek word carries a Latin-letter spelling and a stress guide that are stored with the word as part of the content, not produced on the fly by a converter, which gets Greek stress wrong. The Latin-letter layer can be switched off once you no longer need it.

Greek audio is generated once per word or sentence with a neural voice and then served as a fixed recording, so every listener hears the same clip.

Nothing is generated while you read. Every page is fixed text, prepared in advance and identical for every reader; no page sends anything to an AI model. Before each release, automated checks confirm that every table resolves to real forms and every reference entry points at real content.

None of that makes it error-free. If something looks wrong, it may well be wrong, and a report is the fastest way to fix it.

The reference stays free

The grammar reference is free to read, needs no account, and will stay that way. The course itself is free while it is in development.

Reporting a mistake

Email contact@katafera.com with the page address and what looks wrong - a form, an accent, an explanation that does not hold. Reports go straight to the person who builds the site, and corrections ship in the next release.
