Knowledge is Power.

Baron Buff is a free League of Legends coach that helps you make better decisions in real games. It guides you through champion select with live recommendations and clear reasoning, then gives matchup-specific pre-match direction once the game loads — so you learn by playing, not by reading lectures.

Yes — Baron Buff is free to use. Open it, connect your client, and start drafting with guidance.

Baron Buff is built to be read-only. It doesn't inject code, modify game files, or play the game for you — it only reads draft information and gives advice. We design it to align with Riot's developer policies, but Riot is always the final authority for enforcement.

The Connector detects champion select, reads the live draft state, and updates recommendations as picks and bans happen. You'll see counter options, team fit signals, and composition notes in real time — with the "why," not just a list.

The live draft experience requires the Windows Connector. You can still use baronbuff.com on any device for manual draft analysis — but live, automatic champion select tracking needs Windows.

They're game-specific coaching for what to do next: lane plan, trade patterns, roam/tempo priorities, teamfight approach, win conditions, and which enemies you must respect — all based on both comps and your matchup.

We combine large-scale historical match performance (drawn from many regions and skill levels), current meta strength, and composition logic (damage mix, engage, scaling, waveclear, pick potential). The exact weighting is proprietary — the principle is simple: surface the highest-impact decisions for this draft and this matchup.

Yes. It's distributed through the Microsoft Store and digitally signed. It's designed to be lightweight, read-only, and focused — no bloat, no junk running in the background.

Use the Windows Connector as usual. When you enter champion select, click the Mobile Link icon (top right) and scan the QR code with your phone. It opens the AI Coach in your mobile browser and mirrors the same live draft experience in real time — no app install needed.

Use the Champions section: draft notes, matchup ideas, and pre-match plans generated by the AI Coach — so you can study a champion at your own pace and bring a clearer plan into your next queue.

Baron Buff is built on a data-first methodology. We use official Riot match data as our primary source of truth, then apply statistical models and large language models to turn raw game information into practical recommendations. Our statistical layer detects patterns and measures relationships, while our LLM layer structures game knowledge, interprets context, and generates useful explanations from complex inputs. Coaching VODs and expert educational content are used as secondary inputs — they help the system learn concepts more efficiently, but are treated as signal, not truth, because they can be biased, incomplete, or too context-dependent. We prioritize stronger educational sources and study high-level play to identify cleaner patterns, while recognizing that relevance always depends on context. The goal is simple: use data science and machine intelligence to separate signal from noise and turn evidence into useful in-game guidance.
