Shopify AI translation usage costs

The listing shows Free at $0. Professional is $10 “plus usage charges”. Plus is $20, plus usage again. The estimator prints $0.01 per unit. What is a unit, when does it bill, and when does it not? That search is Shopify AI translation usage costs — not whether the app is “expensive”, which meter is running.

OO - Ultimate AI Translations bills App AI on Professional and Plus *at the translation cost*. Listing estimator: $0.01 per unit. Free does not include App AI; you connect your own model. 0 reviews. Launched 14 October 2026. Do not invent stars.

Related: why that AI price is pitched as fair (no markup pitch). This article is the meter: Free vs Professional/Plus, when usage starts, what the estimator is.

Usage is not a second plan — until App AI runs

Shopify Languages / Markets create locales. They do not bill AI. The translation app does, once *its* model runs.

Two routes, both on the listing:

1. Your AI. OpenAI-compatible base URL, key, model. The app charges $0 for AI. That is Free, and it stays an option on Professional/Plus (“Or use your own AI”).

2. App AI. Professional and Plus only. Usage at that model’s translation cost. Listing estimator: $0.01 per unit. Plus does not cheapen the unit; it buys daily schedule and 5+5 backup slots.

Until the plans sit side by side, shops assume:

• Free means a translation cap. Listing: unlimited languages, markets, translations — while your own AI is connected. No backups, no scheduled jobs, no App AI.

• $10 “includes AI”. No: $10 + usage if App AI runs. Or $10 + your provider invoice.

• Plus is cheaper per unit. Listing: both paid plans $0.01.

None of that is the meter. The meter moves when App AI translates strings.

What the listing estimator shows

Listing (3 Nov 2026):

USD, billed through Shopify. Estimator copy: “AI translation costs”, “Cost per unit $0.01”, “Rounded up to the nearest dollar”. It is a listing estimate, not a Shopify invoice until usage posts.

The listing does not define a unit as a character, a field, or a job. Do not claim “per word” or “per product”. Do claim: ~$0.01 per unit on the listing, pass-through, App AI only on paid plans.

Jobs skip handles, URLs, IDs, SKUs, size codes, JSON, empty source, locked fields. Those rows should not fill the meter. Saved manual edits stay locked; scheduled jobs do not overwrite them — and should not bill them again.

Your own AI: the provider invoices tokens. The app invoices no App AI usage. Free is then $0 for the app. Professional/Plus stay $10/$20 for schedule, glossary, backups — even with App AI off.

When Professional is the first meter

App AI is not on Free. If you will not manage a key, Professional is the first plan where the $0.01 meter exists. Monthly schedule and glossary sit there too. Daily jobs and extra backup slots: Plus.

Catalogue into DE + FR, you already pay OpenAI: Free can translate. You do not schedule. You do not owe Shopify App AI usage.

Same catalogue, no key, a monthly job: Professional, App AI on, estimator as a rough monthly, glossary on so brand names are not “creative” twice.

Draft themes, metaobjects, SEO title/description, image alt, option labels: those types live in the app. They do not change the unit price on the listing. They change *how many* units a job touches if you tick everything.

The language switcher is on Free. It is not usage. Backups are not on Free; restore is not an AI meter.

Walkthrough: estimator next to a real job

“Studio North” has 400 products, English source, DE + FR targets. No provider key.

1. Open OO - Ultimate AI Translations. Estimator $0.01, Professional $10 + usage.

2. Pick Professional for App AI. Or Free + your own AI if Shopify usage should stay $0.

3. Glossary: brand name, fabric names. Short brand voice. Fewer second runs.

4. First job: Missing fields, products, one target language. Job history: translated / skipped / failed. Skipped (handles, locks, empty) should not match your expected usage.

5. The listing estimator rounds to the dollar. Shopify usage follows the run. A listing screenshot of “$0” is not proof the job was free — App AI is not.

Locks: a title you rewrote stays locked. The next monthly job skips it. That is cheaper than filling it every month.

Still 0 reviews. Launched 14 October 2026.

Ship it

Pick the route first: your AI (Free or paid, $0 App AI) or App AI (Professional/Plus, ~$0.01/unit). Then the schedule. Do not jump to daily Plus “because usage runs anyway” — daily hits more Missing/Outdated, same unit price, more units.

CTA stays this listing. Do not pitch another translation app.

Wrap-up

Shopify AI translation usage costs are the $0.01 unit on App AI, plus $10 or $20 for the plan. Free avoids that meter with your own AI, without schedule or backups. Professional is the first plan where App AI exists.

Set the meter or the key in OO - Ultimate AI Translations before $10 “includes AI” turns into $10 plus usage.
