How credits are calculated
Taia measures your translation usage in credits. One credit is one word of Standard AI translation into one language. Understanding how credits are counted helps you estimate costs and choose the right plan.
What counts as one credit?
Each word in the source text costs credits once for every language you translate it into. How many depends on the AI quality tier you choose:
| Tier | Credits per word, per language | Available on |
|---|---|---|
| Standard | 1 | Every plan |
| Advanced | 2 | Pro and Enterprise |
| Premium | 4 | Pro and Enterprise |
So a 1,000-word document translated into three languages costs 3,000 credits with Standard, 6,000 with Advanced and 12,000 with Premium.
When you translate a project, all three tiers use its translation memory and glossary. Advanced and Premium also follow your style guide, for tone and nuance, and Premium is for complex or high-stakes content.
Translation memory doesn't reduce the credits an AI translation uses. It instructs the AI so the first pass comes back closer to what your team approved, which cuts the cost of human review.
Your monthly quota
Every plan includes a monthly credit quota that resets on your billing date:
| Plan | Monthly credits (approx.) |
|---|---|
| Free | 5,000 |
| Basic | 20,000 |
| Pro | 100,000–1,000,000 (selectable tier) |
| Enterprise | Custom |
For exact quota amounts, see the Subscription plans reference.
How quota is consumed
Credits are deducted when you confirm an AI translation. If you cancel a project before confirming, no credits are used.
When you translate a project, the Ready to translate dialog shows the word count and the exact credit cost for your chosen tier before you confirm.
If AI translation of a project file fails, the credits for that file are returned automatically. If some segments come back untranslated and still show as charged, contact support and we'll put it right.
Top-ups
When your monthly quota runs out, you can purchase a top-up: a one-time block of additional credits. Top-up credits are consumed after your subscription quota is exhausted, and they expire at the end of the billing period you bought them in, rather than carrying over. See Buy a credit top-up.
Credits vs Professional translation pricing
Professional translation (human translation) is priced per word as a separate charge, not from your credit quota. Credits only apply to AI translation.
Quota summary
You can see your current credit usage at any time in the Profile → Billing section, or in the quota indicator in the sidebar. It shows:
- Credits used this period
