THE PROBLEM A leaked key or a runaway loop can quietly burn hundreds of dollars before your monthly invoice ever arrives. TKN puts your AI spend somewhere you'll actually see it. ONE DASHBOARD, EVERY PROVIDER Connect your provider billing keys and see today's spend across all of them at a glance, with a per-provider breakdown — no more logging into four separate billing consoles. • OpenAI & Anthropic — organization/admin key • xAI (Grok) — management key • Google Gemini — Google Cloud Billing Spend figures come straight from each provider's official billing API, which reports on a daily cadence. YOUR KEYS NEVER LEAVE YOUR DEVICE API keys are stored in the iOS Keychain — encrypted, never in plain text, and locked behind Face ID. TKN does not upload your provider keys to any server. A KILL SWITCH WHEN YOU NEED IT Something looks wrong? The kill switch is a deliberate, swipe-to-confirm control — designed so you can never trigger it by accident. SPEND RULES Define what "normal" spend looks like and keep an eye on it from the Console. START WITHOUT AN ACCOUNT The whole app runs in a demo mode with no sign-up. Create an optional account — Sign in with Apple, Google, or GitHub — only when you want to sync your setup across devices. You can delete your account and its data from inside the app at any time. TKN PRO Free covers the dashboard for a single provider. Pro unlocks unlimited providers, spend rules, and the kill switch — as a monthly or annual subscription, or a one-time lifetime unlock. Subscriptions auto-renew unless cancelled; manage them anytime in your Apple ID settings. Built by developers, for developers. TKN Pro is available as an auto-renewing subscription (monthly or annual) or a one-time Lifetime purchase. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your Apple ID settings.
