The League companion that plans every level — and tells you out loud.

Not another scoreboard. QueryLoL maps a per-level game plan for all 172 champions, calls out plays in real time while you play, and reads the enemy team — in a ~15 MB native app with no account and no telemetry.

  • 172 champions planned
  • ~15MB native binary

Why it's different

More than an op.gg overlay

Plans every level

A coach-style 18-level route vs your lane opponent, with the right action on each level — for all 172 champions.

Talks to you

Hands-free voice callouts: enemy missing, recall ready, objective spawning, jungler unseen — while your eyes stay on the game.

Featherweight & private

~15MB native Tauri app. No Electron, no account, no telemetry. All requests run locally from your machine.

Reads the enemy

Smurf scoring and premade/duo detection surface who you're really up against — before the game even starts.

Level-by-level plan timeline with per-level actions and spike nodes
01

The signature feature

A game plan for all 18 levels

Power curves, spike bonuses and ult strength are compared level by level against your specific lane opponent, then turned into one concrete action per level — "Lvl 3 trade", "All-in con R", "Farm side", "R2 + objective". Hexagonal nodes pulse on your spikes and color-code each level from dominant to careful.

  • Full coverage for all 172 champions
  • Per-level advantage from power curves + spikes + ult tiers
  • Hover any level for a coach-style tip

In-game overlay

Live advisors — and a voice

Hold TAB for a borderless overlay that thinks with you: a recall optimizer, wave-state advice, death-timer prediction, an enemy-jungle tracker, MIA alerts, vision targets, and a 5-level plan preview. The build strip shows owned / next / future with a gold-needed counter and a "READY" pulse.

  • Voice cues (TTS): "Caitlyn missing", "recall ready, Lost Chapter", "drake in 30s, jungler unseen"
  • Win probability, gold diff & objective timers (Season 2026 timings)
  • Spell-cooldown trackers and power-spike alerts

Champion select & scouting

Win the draft, scout the lobby

Runes, spells and items auto-apply the moment you pick — with alternatives labeled Popular or Best WR. On top of that: pick/ban scored 0–100, per-enemy matchup win rates, team-comp callouts, an all-lanes prediction, and AD/AP damage composition for both teams.

  • Smurf detection — 0–100 confidence from level, WR, games, KDA & champ pool
  • Premade detection — flags duos/parties from shared recent games
  • Adaptive defensive items based on enemy comp

After the game

Improve on the right things

Post-game breaks down both teams with MVP and multikill badges, a gold-advantage timeline, and per-phase (early / mid / late) splits. Your home dashboard benchmarks you against your own baseline and your detected role — so a support is judged on vision, not CS.

  • Role-aware improvement priorities vs your rank's benchmarks
  • Tilt gate after loss streaks, with your historic post-streak WR
  • LP progress chart and per-champion deltas

Frequently asked

Is QueryLoL free?

Yes — completely free and open source. No paid tiers, no ads, no account. The full source lives on GitHub.

Will I get banned for using it?

QueryLoL only uses Riot's official local APIs — the League Client API and the in-game Live Client Data API — to read game state and apply builds you could set yourself. It never modifies, injects into, or automates gameplay, the same approach used by other popular companion apps.

Does it work on macOS and Windows?

Both. It's a native desktop app for Windows and macOS with automatic League client detection on each platform.

Do I need an account or login?

No account and no sign-up. QueryLoL reads your local League client directly and pulls public data from sources like OP.GG and Data Dragon.

How is the app only ~15MB?

It's built with Tauri (Rust) and uses your OS's native webview instead of bundling a full Chromium runtime like Electron or Overwolf apps — so it stays tiny and light on resources.

Stop reacting. Start planning.

One small download. Every level mapped, every callout spoken, every lobby scouted.
