Features

Dictionary of 260,000+ word forms
Unambiguous cases (берёза, ёж, идёт, тёплый) get the letter ё automatically — powered by the eyo dictionary, the same data the best yoficators use.
Ambiguous cases are your choice
Words where both е and ё are valid (все/всё, берёт/берет, нёбо/небо) are highlighted yellow. Choose the right one by meaning in a single click — with an explanatory hint.
Capitals and headings
Restores ё even in all-caps words: БЕРЕЗА → БЕРЁЗА, ЧЕРНЫЙ → ЧЁРНЫЙ. Most yoficators silently skip these.
Names and surnames
Recognizes ё in proper names — Артём, Алёша, Семён, Фёдоров. This matters for documents: an «е/ё» mismatch in a surname can cause legal trouble.
Reverse mode — remove ё
Need the opposite? «Remove ё» mode replaces ё with е across the whole text — for systems and fonts without ё support.
Copy, download, import
Copy the result, download a .txt file, or load text by dropping a .txt file onto the input.

FAQ

What is a yoficator?

It is a tool that automatically puts the letter «ё» back into text in place of «е» where it belongs. It runs on the eyo dictionary (260,000+ word forms) right in your browser, with no installation.

Why do some words stay unchanged?

Some words are unambiguous (берёза is always with ё), while others are ambiguous: «все» vs «всё», «берёт» (he takes) vs «берет» (a beret), «нёбо» (palate) vs «небо» (sky). The tool does not change these on its own — it highlights them so you choose the right variant.

Does it add ё to names and surnames?

Yes. Артём, Алёша, Семён, Фёдоров and many more are recognized from the dictionary. This is especially important for documents — an «е/ё» mismatch in a surname can cause disputes with banks, notaries, and inheritance.

Why write ё at all?

The letter ё removes ambiguity (все/всё, узнаём/узнаем, нёбо/небо), shows the correct pronunciation when reading aloud, and is required in proper names, documents, and texts for children and Russian learners.

Can it remove ё from text instead?

Yes. Switch to «Remove ё» mode and the tool replaces every ё with е. This is useful for legacy systems, databases, and fonts that do not support the letter ё.

Does it handle large texts?

Yes. Processing runs in your browser and takes a fraction of a second even for an article of several thousand words — you can paste entire chapters.
