Honest comparison

KAERIS vs POEditor

POEditor and KAERIS both keep it simple. The difference is the verification: KAERIS reads every translation back into your language to catch the errors that still read fine on the surface.

What it costs

Entry price, side by side

POEditor's entry plan is cheaper than ours in dollars, and it is fair to say so. It is also a different unit: they meter strings you store, we meter characters we actually translate — 200,000 per file and 30M a month, with no ceiling on how many strings you keep.

Questions

FAQ

How is KAERIS different from POEditor?

Both are lightweight and get out of your way. KAERIS adds read-back: every string is back-translated by an independent model and checked for meaning drift, plus a deterministic placeholder/tag check. And it starts free with no account.

Can I move my .po / JSON files over?

Yes — export from POEditor and drop the file in. For .po, KAERIS writes the correct Plural-Forms for each target language and keeps msgctxt distinct; JSON keeps its nesting. No account needed to try.

Does it keep my terms consistent?

List brand/product terms as glossary entries and KAERIS keeps them verbatim across all 46 languages — and flags any that don't survive as a fact, not a guess.

I need contributors to collaborate on strings — is KAERIS enough?

If shared contributor management is central to your flow, POEditor is a fair choice for that. KAERIS is a translate-and-verify tool, not a collaboration platform.
