What you get
Advice that explains itself
Every turn, five suggestions with plain reasons: who it works with, who it beats, what your team is missing.
A win chance you can read
See how champion strength, teamwork, head-to-head matchups and side add up, updated after every pick.
Scouting
Draft against a sample team: see each player's favourite champions and what they're likely to pick next.
A coach's report
When the draft is done, get a grade, every lane matchup and a game plan. The AI writes it only when you ask.
How it works
- 1

Choose blue or red side, the format, and an opponent to scout.
- 2
Draft
Ban and pick in the real pro order while the practice opponent answers.
- 3
Review
See your grade and lanes, then read the coach's plan for the game.
New to drafting? Each team bans five champions and picks five, taking turns in a fixed order: three bans each, three picks each, two more bans, two more picks.
About Synapse
Synapse began at the Cloud9 × JetBrains hackathon in 2026 as a draft assistant built on pro match data. That database is gone, so today's Synapse runs on estimated champion stats and made-up sample teams: treat the numbers as practice guidance, not scouting of real players.
It's free, has no accounts or ads, and saves your drafts only in your browser.
