Kalshi + Polymarket
Auto-import your Kalshi & Polymarket fills, then see what actually makes you money — by category, by venue, by how long you hold. Fees included, math you can trust.
Free forever plan · No card required · Read-only imports
Stock and options journals can't import a Kalshi API key or a Polymarket wallet, don't understand contracts that settle to $1 or $0, and have no idea what "politics" or "weather" edge means. So prediction-market traders end up in spreadsheets — or flying blind.
Paste a Kalshi API key (read-only) or a Polymarket wallet address. We pull your fills and settlements, normalize them, and group them into positions. CSV upload too.
Realized P&L with fees folded in, weighted-average cost on partial closes, and correct settlement to $1/$0. The number is the whole point — we get it right.
Win rate and average win/loss broken down by market category — politics, sports, weather, econ, crypto — and by venue and day of week. Find where your edge actually is.
Notes and tags on every position: your thesis, your setup, your mistakes, your emotions. Review your losses and stop repeating them.
See P&L by holding duration — an early read on whether your edge fades the longer you sit in a position.
We never place trades. We never sell your data. Delete everything on request. Read-only, from day one.
Start free. Upgrade when your book outgrows one venue.

We ask for a read-scoped key and encrypt the private key at rest. We only read fills, positions and settlements — we can't place or cancel orders.
No. Polymarket import is fully read-only: you paste your public wallet/profile address and we read your on-chain trade history. No keys, no signatures.
Per position (one market, one side), using weighted-average cost for partial closes, with trading fees subtracted and settlement to $1 or $0 per contract. For Kalshi we use the exchange's reported per-fill fee; for Polymarket there are no trading fees.
Kalshi and Polymarket today. Those are the venues generic journals ignore — so that's where we started.
