**Short version.** Polymarket built a great prediction-market exchange with a UI aimed at casual bettors. Polyterminus is a separate trading terminal that sits on top of that exchange for people who want to trade it professionally — the way a Bloomberg Terminal sits on top of stock exchanges. We never custody your money; every trade signs against your own Polymarket wallet.

## Who is it for?

  - **Volume scalpers** who need real-time WebSocket ticks, one-tap $1 buys, and a grid of "Up or Down" markets they can react to in seconds.
  - **Whale-followers** who want to see which wallets are actually making money on Polymarket, filter them by category, and mirror new positions.
  - **Systematic traders** who want to chain triggers → AI steps → actions (agents), plug in their own AI provider key, and automate the boring parts.
  - **Serious hobbyists** who want a daily AI brief on their watchlist, a proper risk gate, and a cleaner UX than eyeballing 12 Polymarket tabs at once.

## Who is it NOT for?

If you're opening one Polymarket bet a month on the presidential election, the native UI is already perfect. You don't need this. Polyterminus starts paying for itself somewhere around "I check Polymarket every day".

## How we make money

Free tier is genuinely free forever — one shared AI budget, one-click trading, whale leaderboard, scalp pit. Pro is $19/mo and unlocks higher AI quotas, copy-trading autopilot, and custom agents. Founder plan (call us) is for whales and funds. We never take a spread on your trades — orders go straight to Polymarket at their fees.

## Non-custodial forever

This isn't marketing. Your Polymarket credentials sign every order. We only ever hold the ability to place orders on your account — never to withdraw. If Polyterminus vanished tonight, your funds and positions would be entirely untouched on Polymarket tomorrow morning.
