The toolkit

Everything you need to find an edge

A professional-grade optimizer and a true contest simulator, in one fast workspace.

AI Coach

A chat coach that reads your actual slate — projections, ownership, your lineups, and sim results — for leverage plays, stacks, and cash-vs-GPP calls in plain English. Grounded in your numbers; it never invents injury news or info it wasn't given.

Smart optimizer

Generate up to 150 unique lineups with salary optimization, per-team limits, min-unique constraints, exposure caps, and player locks/excludes.

Contest simulator

Monte Carlo every lineup across thousands of sims against an ownership-weighted field. Get projected ROI, cash %, and top-1% rates before you enter.

Exposure & leverage

See player and team exposure across your whole pool, compare to field ownership, and find the leverage spots that win tournaments.

Built for speed

10,000-sim runs in seconds, right in your browser. Paste a slate CSV and you're building in under a minute.

Multi-sport

NBA, NFL, MLB, and PGA — DraftKings and FanDuel roster rules built in, including flex and stacking-aware positions.

Export anywhere

Round-trip your DraftKings entries file or FanDuel's CSV Edit file — SharpStack DFS writes your players straight into it, entry IDs intact — or write FanDuel's bulk upload file for brand-new entries. Build here, enter there.

Workflow

From slate to submitted in three steps

Load your slate

Paste a projections CSV or start from a sample. Name, position, salary, projection, ownership, team.

Build your pool

Set your strategy, constraints, and exposure caps. Generate a diverse, optimized set of lineups instantly.

Simulate & submit

Run the contest simulator, sort by projected ROI, export the winners, and enter with confidence.

The simulator

Know your ROI before you pay the entry fee

Most tools stop at projections. SharpStack DFS samples every player's outcome from a calibrated distribution, builds a realistic opponent field weighted by ownership, and ranks your lineups across thousands of contests.
