Frequently Asked Questions
Is there a free plan?
Yes. Free includes every board (Today, Smart Money, Insiders, the 8-K radar, Activists, Sectors and Macro) for the last 3 months, company pages, the AI summaries that already exist, 5 AI research questions a month and 3 follows. No credit card needed.
Can I try Pro for free?
Yes. Sign up and you get Pro for 7 days with no card (50 AI research questions during the trial). When it ends you move to Free and are not charged. If you add a card for Pro monthly during the trial, you get another month free after it ends, then $29 a month. One trial per account.
What counts as an AI research question?
Each message you send to AI Research counts as one, on the web or in the Android app, including follow-ups. The count resets each month on your billing day (on the calendar month for Free). Reading filing summaries, boards and company pages never counts.
What is the difference between reading a summary and running an AI analysis?
SignalX already summarizes thousands of 10-K, 10-Q and 8-K filings, and anyone can read those. Running a new analysis, for a filing that has not been summarized yet or in Korean, generates it on demand with AI and is part of Pro and Premium.
Can I upgrade or downgrade anytime?
Yes. An upgrade takes effect immediately and starts a fresh monthly allowance from that day. A downgrade or cancellation takes effect at the end of the current billing period, and you keep your plan until then.
Is the developer API included?
No. The API is billed separately with prepaid credits at $0.10 each (minimum $5), on any plan. A /v1/chat request uses 1 credit per 10,000 tokens and /v1/search uses 0.2 credits.
Does my plan work in the Android app?
Yes. Sign in with the same Google account and your plan, follows and AI allowance carry over between the web and the Android app.
Can I get a refund?
See the refund policy for the details. You can cancel anytime from Settings, and your plan stays active until the end of the period you paid for. Refund policy
Is this financial advice?
No. SignalX organizes and summarizes public SEC filings for research. It does not recommend buying or selling any security.
