During champion select, DRAFT ranks the champions you play against the enemy composition, highlights the best fits and explains how to play each one. It never picks, bans or locks in a champion for you: the decision stays yours.
In champion select you watch the enemy team come together, but you have little time to work out which of your champions handles it best. DRAFT does that reading with you, using explicit rules, and lets you decide.
Engage, divers, crowd control, squishy targets: the enemy team profile at a glance.
Every champion in your pool is ranked, with an alternative and what separates them.
A game plan for each phase and tips matched to your level, so you learn while playing.
Screenshots of the DRAFT 2.16 beta interface, with a simulated draft and fictitious data. Each feature shows its maturity level. The app is currently in French.
Compact panels show the essentials: enemy composition, your pool's ranking and the game plan. They sit next to the client window.
Experimental Automatic opening: to know when a champion select starts, DRAFT compares a tiny thumbnail of the client window (96 × 54 pixels, in memory, never saved) with what it has learned. It can be turned off from the tray icon menu.
Top, Jungle, Mid, ADC, Support: each role keeps its own champions. Switch roles in one click and export your profiles to a file.
Experimental If you enable client reading, DRAFT can suggest the profile for the position League assigns you. It only switches roles by itself if you choose so.
The win condition, threats, targets and useful bans, then tips for laning, mid game and teamfights. These tips are hand-written and still being reviewed.
Criterion by criterion, DRAFT shows what puts one champion ahead of another. When two options are very close, it says so instead of choosing at random.
If you import your ranked history, DRAFT shows your most played champions. These numbers inform you; they never change the strategic ranking.
An icon appears next to the Windows clock. No account and no key are needed.
In settings, add the champions you play for each role. They are saved on your PC.
Type each enemy champion once it is locked in, or enable optional client reading to add them for you. Their guessed role can be corrected in one click.
Your ranked pool, the reasons and a game plan. You select and lock in yourself, in the client.
Launch, profiles, entering enemy picks, reading the ranking, panels, tabs and Riot import. The video only plays when you click it.
The core ranking works without any request to Riot. The official API powers three optional features, always started by the user from the settings or the tray icon menu. They are described as they work in version 2.16 beta.
The user enters one or more Riot IDs, a region and how many games to read (100, 200 or 500 per import). The tool is meant for the user's own accounts; in the beta, nothing verifies ownership (see Riot Sign On below).
ACCOUNT-V1 /riot/account/v1/accounts/by-riot-id/{gameName}/{tagLine}MATCH-V5 /lol/match/v5/matches/by-puuid/{puuid}/ids?queue=420MATCH-V5 /lol/match/v5/matches/{matchId}Kept on the PC until deleted: the Riot ID entered; for each ranked solo/duo game longer than 5 minutes, its ID, date, patch, duration, champion, position, result, K/D/A and the enemy champions. No name or identifier of any other player.
Shown: most played champions and records in the Games tab.
To guess the enemy champions' roles, especially mid, DRAFT counts positions played over about 1,000 recent ranked games (last 14 days). It takes about 40 minutes.
LEAGUE-EXP-V4 /lol/league-exp/v4/entries/RANKED_SOLO_5x5/{tier}/II?page=1 — Silver to Emerald, starting pointMATCH-V5 match lists (5 games per player) and match detailsKept: champion × position counters per patch, the IDs of matches already read and a few compositions (champions only) used to measure how accurate the guesses are. Starting players stay in memory and are never saved.
For the "direct matchup" criterion, DRAFT measures how the pool's champions fare against their same-position opponent over the last 30 days. It starts from the same lists, then follows, in memory, players who play those champions. At most 3,000 requests, about 65 minutes.
LEAGUE-EXP-V4 same starting point as aboveMATCH-V5 ranked solo/duo match lists and detailsKept: wins and games per pool champion and per opponent, per patch, and the IDs of matches read. Below 30 games for a matchup, the record is not used and the hand-written table remains the reference.
In the beta, each user enters their own development key. It is masked on entry, sent only to Riot in the X-Riot-Token header, never in a URL, and is neither stored nor logged.
At most one request every 1.3 seconds, below a personal key's limit (100 requests per 2 minutes). On a 429 response, DRAFT waits for the Retry-After delay. On 401 or 403, it stops.
Matches already read are never requested again. A recent role computation (under 3 days) is not rerun, and the next import resumes where the previous one stopped.
The League client's local API runs on the player's PC: it is not the public Riot Developer API, and Riot states it is not officially supported for third-party applications. If the user enables it, DRAFT only sends read requests (GET) to two local endpoints: /lol-gameflow/v1/gameflow-phase and /lol-champ-select/v1/session. It keeps the phase, enemy champions already locked in and the player's assigned position. It ignores names, identifiers, hovers, allied picks and bans. This use will be declared in the registration request to Riot.
Champion artwork and the version list are loaded from ddragon.leagueoflegends.com, Riot's static content service. No key is needed.
A production key cannot be embedded in a distributed app. The project therefore plans a DRAFT server that would keep the key, compute aggregated statistics (roles and matchups) once and distribute them as anonymous counters. The app would no longer need any key, and the total number of requests sent to Riot would drop sharply. Personal history import would go through Riot Sign On, so that each player only imports their own accounts.
DRAFT is designed to follow Riot Games' policies for third-party tools: it highlights several options and their reasons, without deciding for the player. It is not yet registered with or approved by Riot.
DRAFT's data stays on the user's PC. There is no DRAFT account, no DRAFT server, no ads and no telemetry.
Privacy policy ↗Version 2.16.0 is available as a public beta on GitHub. It includes role profiles, assigned-position suggestions and signed in-app updates. Automated tests pass, but real champion-select tests and tests on other PCs are still needed. Educational tips are being reviewed; client reading and automatic panel opening remain experimental. Version 2.16.0 can be downloaded from GitHub.
