Common questions

Can I cancel my subscription?

Yes — cancel any time from your Stripe billing portal. You keep Pro access until the end of the billing period, with no fees.

What payment methods do you accept?

All major credit and debit cards via Stripe (Visa, Mastercard, Amex). Apple Pay and Google Pay are available where supported by your browser.

Do I need an account to try Lexio?

No — the free tier works without signing up. You get 30 lookups and 3 OCR scans per month. Sign up only when you want to save words or upgrade to Pro.

Is my payment information stored by Lexio?

No. All payment processing is handled by Stripe. Lexio never sees or stores your card details.

Which AI model is best?

Claude Sonnet gives the most nuanced, literary definitions — ideal for dense non-fiction or literary fiction. Haiku is faster and perfectly accurate for everyday words. GPT-4o Mini and Gemini Flash offer useful alternative perspectives.

I upgraded but my account still shows Free?

Activation is normally instant. If it doesn't update within a few minutes, refresh the page. If you still see Free after 5 minutes, email hello@lexio.site with your receipt and we'll fix it immediately.
