Pro Lifetime — Founding Members
FOUNDING 200All Pro features, forever. No recurring payments. Only 200 spots — closes for good after that.
How does Pro Lifetime work?
What: One-time payment for the Pro plan, used forever. No recurring fees, no plan expiration.
Why: We're opening 200 lifetime spots as a thank-you to early adopters who bet on i1n before it's a household name. Once the 200 spots are gone, lifetime closes for good.
Caps: You stay on Pro caps forever — 2,000 keys, 3 languages, 2 projects, 3 seats, 10,000 AI translations/month. If you need Business limits later, you'd switch to the recurring $99/mo plan.

Frequently asked questions
What counts as an AI translation credit?
One AI translation costs 1 credit. Cache hits cost less — from 0.2 credits on Starter down to 0.01 on Enterprise. Translating 100 keys to 3 languages consumes 300 credits if none are cached.
Are viewer seats really unlimited?
Yes. Every plan includes unlimited viewer seats. You only pay for admin and editor seats that can modify translations.
Is the CLI free?
Yes. The CLI, SDK, and MCP server are free on every plan, including Starter. You can push, pull, and generate type definitions at no cost.
Can I switch plans anytime?
Yes. Upgrade or downgrade from the dashboard at any time. Changes take effect immediately.
What's the difference between cache types?
Public cache shares translations across all Starter users — common strings are instant and cheap. Mixed cache checks your private cache first, then falls back to public. Private-first and Dedicated caches isolate your translations completely.
How does annual billing work?
Annual billing gives you 12 months for the price of 10 — saving you 2 months per year. You can switch between monthly and annual at any time.
What is the Pro Lifetime Deal?
We're opening 200 lifetime spots for our Pro plan — pay once, use forever. The first 50 spots are $199, next 50 at $249, and the last 100 at $299. You get every Pro feature ($29/mo equivalent): 2,000 keys, 3 languages, 2 projects, 3 seats, 10,000 AI translations/mo, Brand Voice AI. Lifetime stays locked at Pro caps — if your team outgrows Pro, you'd switch to the recurring Business plan. After 200 spots, lifetime closes for good.
