Common questions
What's the difference between Lite and Spark?
Lite gives you the upgraded model plus 5 Research searches a month for $8. Spark gives you the advanced reasoning model, 15 Research searches a month, priority compute, and the highest limits — for $20.
How does the message limit work?
Every plan has a session-based message budget — Free 25, Lite 80, Spark 250. The session is a rolling 4-hour window, so capacity returns as your oldest messages age out. You can see exactly where you stand any time in Settings → Usage.
Can Free users use Think mode?
Yes. Quick, Auto, and Think are all available on Free. Research mode is the one feature that requires a paid plan (Lite or Spark) because it pulls live web pages with citations.
Can I switch or cancel anytime?
Yes. Manage your subscription from Settings → Account. You keep your tier's features through the end of the current billing period after cancelling.
Do unused Research searches roll over?
No — Research resets on the 1st of every calendar month. Use 'em or lose 'em.
Are payments secure?
Yes. Payments are processed by Polar.sh. We never see or store your card details.
