There is a free plan that allows a limited number of queries each day. Paid subscriptions add more usage and are billed through Stripe. ### How do I submit a problem? You can type it, paste text, or upload a photo. Feen reads equations, diagrams, and word problems, then returns a step-by-step solution in seconds. ### Does it just give the final answer? No. It breaks each problem into steps and explains why each one matters, so you can apply the method to similar questions yourself. ### Can I cancel or get a refund? You can cancel anytime in account settings. The site says refund requests can be made within 7 days of payment by emailing their support address. ### Feen AI 的每月流量與成長趨勢為何？ Feen AI 目前每月有 4802 次造訪，月流量變化為 +768（成長率 +19%）。其主要來源市場為美國（佔比 100%），其中包含每月 1517 次直接造訪與每月 — 次自然搜尋造訪。 ### Feen AI 是免費的嗎？其定價模式為何？ Feen AI 採用免費增值定價模式。Free plan with a daily query limit; paid subscriptions are available and billed via Stripe, with cancellations allowed anytime. 支援的帳務與結帳平台包括：未列出。 ### 2026 年最佳的 Feen AI 替代方案有哪些？ 依據 OpenAITools.app 的分類流量與功能契合度，Feen AI 的前五大替代方案為：1.
