Common questions
What's the difference between Lite and Spark?
Lite gives you the upgraded model plus 5 Research (deep web) searches a month for $7.99. Spark gives you the advanced reasoning model, 15 Research searches a month, priority compute, and the highest session limits — for $20. Quick web lookups are included in every mode on both.
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.
How do Research searches work?
Research mode runs a deeper multi-source web search with citations. Lite includes 5 and Spark 15 per 30-day cycle (which starts from your first message). Quick one-off web lookups inside Quick/Auto/Think aren't capped — they're included in your session budget.
Are payments secure?
Yes. Payments are processed by Polar.sh. We never see or store your card details.
