Billing FAQ

Do I need a credit card for Hobbyist?

No. Hobbyist is genuinely free — no card required, no trial expiration.

Can I cancel anytime?

Yes. Cancel from your account settings at any time. Monthly subscribers lose access at end of billing period. Annual subscribers get access through their paid year.

What's the difference between monthly and annual?

Annual billing saves you 33% (2 months free). Same features, same plan — just billed once per year.

What is the AI Power Pack?

ReefBot is powered by AI APIs that cost us money per query. The Power Pack add-on ($4.99/mo) unlocks unlimited AI queries on any paid plan, covering our API costs and keeping base plan prices low.

What counts as an AI query?

Any message you send to ReefBot counts as one query. Automated insights and alerts do not count against your limit.

Can I switch plans?

Yes, upgrade or downgrade anytime. Upgrades take effect immediately; downgrades take effect at your next billing cycle.
