What RotoBot is
RotoBot is an AI research assistant for prop bettors and fantasy football managers. You ask it questions in plain language, and it reasons across lines, game logs, injury news, defensive splits and matchup history.
An AI assistant like this does not place bets or promise outcomes. It gathers and explains information so you can decide faster. It works on web, iOS and Android.
Who RotoBot is for
It fits bettors who like asking questions rather than browsing tables. If you would rather type "which receivers face a weak defense this week?" than build a filter, the chat format helps.
It also suits fantasy football players. League sync works with Sleeper, ESPN and Yahoo, and the tools include trade grades, start/sit calls and a draft board.
It is a weaker fit if you want a scanner for +EV bets or arbitrage. RotoBot is research, not price scanning. It is also a weaker fit if you want a full free product, since the app requires a subscription for all features.
How it works
The main pieces are:
- AI chat: a research agent you can ask about a player, a game or a prop.
- Prop Analyzer: a deeper look at a single player prop.
- Insights feed: curated prop edges, such as hit-rate trends, defensive vulnerabilities and usage shifts, surfaced for the slate you care about.
- Parlay generator: you choose the number of legs, the games and the odds range. Parlays are labeled correlated or decorrelated.
- Fantasy tools: a trade analyzer for dynasty, keeper and redraft deals, plus league-aware start/sit advice.
- Free NFL stat explorer: browse situational research without signing up.
There is also an MCP server for connecting RotoBot to other AI assistants. It needs an account and an active subscription.
Alerts can notify you when a line moves, and your research history syncs across devices.
If a parlay appeals to you, remember that legs multiply the book's margin. The no-vig calculator and odds converter show what the prices really imply.
What to weigh before subscribing
Subscription is required. The app lists a paid subscription for all features, though the NFL stat explorer is free to browse. See the at-a-glance table above for current pricing and trial terms.
Trial rules are specific. The terms say weekly plans have no trial and bill right away, and each user gets one trial per plan type. Read the purchase screen carefully before you start.
Refunds depend on where you buy. Web charges are generally non-refundable once a billing period begins, with legal exceptions. App-store refunds go through Apple or Google.
Fantasy tools are NFL-only. The betting and research suite covers more sports, but fantasy features focus on football.
AI answers need checking. A chat assistant can sound confident and still be wrong. Verify injuries, lines and stats before you bet.
We found no stated sportsbook coverage. If you need a particular book's prices, confirm that in the app.
Bottom line
RotoBot suits prop bettors and football fantasy players who want to ask questions and get matchup research quickly. If you want automated edge scanning, or you don't want to pay for a research tool, look elsewhere. Browse the free NFL stat explorer first to see if the approach fits how you work.
