AI analyses are explainable assistance — never a price prediction.

Before the crowd

Diamonds in the rough. A whisper from Mantis.

The names the crowd hasn't priced yet. The setups that haven't aired yet. Mantis hands you both, quietly, before the room knows.

Diamonds in the rough VALUE

Five names where price and value disagree.

Each morning, the screener surfaces names trading below what the business looks worth. Five different reads — earnings, growth, what the assets are worth, what the cash flow implies, and what analysts who follow the name expect — blend into one number per stock. The wider the gap and the more reads agree, the higher the confidence label.

Common questions.

Is my data secure?
All data is encrypted in transit and at rest. We never sell your trade data, period.
Do I need a brokerage account?
No. Mantis is a research and journaling tool. You log your trades after they happen — we don't connect to a broker.
What's the difference between Free, Essential, and Pro?
Free gets you the trade journal, position sizer, and risk manager. Essential adds the screener and sentiment. Pro unlocks Smart Money flow, whale tracking, macro regime, AI earnings summaries, and pattern analytics. See the pricing page for the full breakdown.
Is a card required for the trial?
Yes — we use Stripe to verify your card before starting the 14-day trial. We won't charge until day 15, and we send a reminder email 3 days before that.
Where is Mantis available?
Anywhere the App Store and Google Play distribute. EU pricing in EUR; US pricing in USD; we accept payment in both.
