The core of the product

Every pick gets one of three verdicts.

Most tools rank everything and recommend something. Devil Drafts audits instead — against live data, the contest's actual rules, and a strategy playbook refined across formats. When the data isn't there, it says so.

[ Clear ]

The data checks out. The line is sourced from a real book, participation is confirmed, and the pick fits the contest format you're actually playing.

[ Flag ]

A real, sourced concern. Stacked risk in one entry, correlated legs, or a parlay of heavy favorites whose payout no longer justifies the risk — named specifically, with the reason.

[ Unverified ]

Missing data is not a guess. No confirmed lineup, no posted line, no sourced number — the pick is flagged unplayable until it's verified. The analyst never fills the gap with an invented stat.

What's inside

One board, every format.

Line shopping
The same bet, at the best price on the board. Every book's number is compared and the best one is quoted, with the book named and the gain over the typical price shown. Tell it which books you actually hold accounts with and it only compares those — a better number somewhere you can't bet isn't an edge. This is the one gain here that needs no opinion about the game: taking −125 instead of −145 on the same bet can't be wrong.
Live odds board
Real sportsbook lines — moneylines, spreads and totals for NBA, WNBA, NFL, MLB, soccer (EPL) and MMA, plus outright markets for golf tournaments. Player props where the books post them: NBA, WNBA, NFL, MLB and soccer. Everything ranked by implied probability with the vig shown, not hidden, and injury reports checked automatically so a prop on a player who is ruled out gets flagged before it reaches your slip.
Parlay builder
Tap picks onto a slip and watch the true combined probability and expected value update live — with the book's vig stripped out, not baked in. Mix legs from different sports in one slip, and see EV stated in cents per dollar even when that number is negative.
AI analyst
One tap audits your whole slip or pool against the playbook: cut risk, drop budgets, correlated legs, format traps. Every number it cites is sourced or it doesn't cite one.
Tier value board
Upload a tiered picksheet and each tier's players are ranked by live win odds — or by your own projections when you have a stronger read. On tiered contests, anyone still on the sheet who isn't in the event's actual field is caught and dropped, so a withdrawal never reaches your entries.
Splash Sports export
Built for Splash Sports pick'em and tiers contests. Upload the picksheet you download from splashsports.com, auto-fill every entry under the contest's real rules — distinct lineups, team limits, exposure caps — then download a CSV in Splash's exact import format. A guard blocks the download if two entries came out identical. Your picks stay yours; nothing is ever submitted for you.
Paste-odds mode
Odds load themselves — for game lines you never type a number in. Where no feed posts a market (golf and MMA player props, niche leagues), paste the odds from any book and they become the same ranked, checkable board. No event is out of reach.

What this tool will never do.

Devil Drafts was built by a bettor tired of tools that dress up guesses as data. The whole system runs on one rule: a confidently stated number is not a verified one.

  • No guaranteed picks, locks, or "can't-miss" plays — they don't exist
  • No invented stats — every number traces to a source or gets cut
  • No fake urgency, streaks, or fabricated win rates
  • No auto-betting — you review and submit every entry yourself
