Live draft analysis

Every pick, scored the moment it lands

With Champion Select open, Mejais mirrors all picks and bans and ranks the strongest champions left on the board — so you always know the best call under the timer.

  • Three-axis scoring: OP strength, SY synergy, CO counters.
  • A “why this pick” breakdown in plain language.
  • Live team-composition meter: AD/AP, frontline, roles.
02
Explore the roster

Know every champion, every matchup

Browse all 170+ champions with win rates from high-ELO ranked play. Filter by role, sort by performance, and open any champion to see who they beat and who beats them.

  • Role filters and win-rate / games sorting.
  • Favorable and challenging matchups, with magnitude bars.
  • Refreshed every patch from aggregate statistics.
03
Built around you

A champion pool that tips close calls your way

Build a pool of the champions you actually play and Mejais weights them in every draft — so when two picks are nearly equal, your comfort picks come out ahead.

  • Pool champions get +0.10; starred favourites get +0.50.
  • Discover picks by role with a swipe deck, or search the whole roster.
  • Reorder your pool, set a main, and track its overall strength.

This demo ranks by win rate (OP) only, on real patch data — so the team it builds is just a taste. The full app also weighs synergy and counters, explains every call, and learns your pool. See how Mejais compares ↓
Why Mejais

The demo ranks win rate. Mejais drafts the whole picture.

Most companion apps stop at raw win rate — which is why the demo above can't really tell you who to draft. Mejais scores every pick on three axes, explains the call, and builds around the way you actually play.

FAQ

Questions, answered

Is Mejais allowed — can I get banned for using it?
Mejais is read-only. It never modifies, automates, or interacts with the game; it only reads your Champion Select and shows statistics. It runs on Overwolf, the vetted overlay platform used by many popular League apps. As with any third-party tool, use it at your discretion, but it is built to stay firmly within the lines.
Which platforms does it support?
Mejais runs on Windows via the Overwolf platform, alongside the standard League of Legends client.
Does it work on my server / region?
Yes. Recommendations are built from aggregated high-ELO match statistics that apply regardless of your region, and the app reads your local Champion Select directly.
Do I need to log in with my Riot account?
No account or login is required. Mejais reads Champion Select through the local League client, and nothing about your games leaves your machine.
How much will it cost?
Mejais is still in development. Pricing and availability will be announced at launch — follow on X to be the first to know.
When does it launch?
The app is built and whitelisted by Overwolf, and is currently pending Riot's approval. See the roadmap above for the latest status.
