$10 = 4,000 credits that never expire. Available to Pro & Premium subscribers — top-up credits stack on top of your monthly allotment.
A credit is the unit you spend when the agent runs on our models. A quick factual answer costs a little; a deep, multi-step research run with code, charts, and web searches costs more — so you only pay for the depth you use. Tools have a fixed cost on top: a web search is about 16 credits. You can watch your balance live and top up anytime.
On Free, you wait for the daily or monthly refresh. Pro and Premium have no daily cap, and you can buy top-up packs that never expire — or bring your own model key and keep working without spending platform credits at all.
No. Top-up packs ($10 = 4,000 credits) never expire and stack on top of your monthly allotment. Your monthly allotment refreshes at the start of each billing cycle.
Anytime. Upgrade, downgrade, or cancel whenever you want — no contracts. Changes take effect from your next billing cycle, and you keep any top-up credits you've already bought.
Yes. Bring your own model keys — Claude, GPT, Gemini, and others — and those runs don't consume platform credits; you pay your provider directly.
Every plan covers A-shares, US, and Hong Kong markets with real-time quotes, fundamentals, filings, and news — the same full data access on every tier.
Every plan runs the full research agent. Higher plans unlock more capable models — Free uses our standard models, Pro adds advanced models, and Premium unlocks our most capable models for the deepest analysis. Bring your own keys on any plan to use your provider's models directly.
Run your first analysis today, then move up the moment you need more credits and our most capable models.
