Built around how SaaS teams actually ship

Translation isn't a marketing surface. It's part of your deployment.

The CLI is the contract.

@i18nnn/cli login , pull , status . The cloud is the single source of truth — keys live in your project, translations flow to your repo as files.

BYOK. You pay your AI, not us.

Bring your own OpenAI or Anthropic key. We don't take a margin on tokens. Default quota of 1,000 / 10,000 / 100,000 calls per month on Free / Pro / Team, used as a rate guard.

How AI keys work

Roles, not comments in a spreadsheet.

Five roles per project: Owner, Admin, Translator (per language), Reviewer, Viewer. Invite translators by email, scope their language, audit every change.

Roles explained

CLI · @i18nnn/cli

One command. Local repo in sync with the cloud.

No push, no merge conflicts, no drift between staging keys and production keys. You edit in the cloud, you pull from the cloud.

Device-code login

Authenticates against your work email. Tokens stored in ~/.config/i18nnn/credentials.json .
Idempotent pulls

Re-running pull overwrites only what changed in the cloud. Existing keys in your files are preserved.
Smart merge

Detects your existing flat or nested layout. Generates the right shape on first run, never reformats.

AI translation · 07

Translation that learns your product.

Every project carries a glossary, a brand voice note, and per-key context. The model uses them every time it touches a value.
