Oak – AI Battle Coach

Oak is your AI battle coach — a chat companion for building and reasoning about competitive creature-battle teams. Ask any question about your roster and get a reasoned, cited answer, not a stat dump. Most reference apps hand you raw numbers and leave the thinking to you. Oak reasons on top of the data: every answer comes with its reasoning, the sources it's grounded in, and explicit "this part is inferred" flags whenever the data doesn't fully cover your question — so you always know what's fact and what's a best guess. WHAT YOU CAN DO • Build full competitive teams — set species, ability, held item, all four moves, nature, EVs, IVs, and Tera type for every slot on your roster. • Import and export teams using the popular Showdown text format — bring a team in from a calculator or a friend, or take yours out to use elsewhere. • Ask anything in plain English and get the direct answer plus the reasoning behind it, with cited sources and clear flags when something is uncertain or inferred. • Switch your entire chat and team builder to the official competitive regulation format with one toggle — no separate app, no manual rule lookups. • Attach a photo or screenshot — a team sheet, a card, an in-game moment — and ask Oak about it directly. • Drill into any move, ability, type matchup, or damage calculation in a dedicated detail view without losing your place in the conversation. • Start chatting instantly as a guest, no account required. Sign in with a one-time email code (no password) when you want your chats and teams saved and synced across devices. Oak is free to use, with no in-app purchases.
