Questions
Live stats and schedules from the official MLB Stats API, rest-of-season projections from FanGraphs Steamer, advanced Statcast metrics from Baseball Savant (xBA, xSLG, xwOBA, exit velocity, barrel rate), and your league’s roster, standings, and scoring from Yahoo or ESPN Fantasy. Every recommendation cites its data source.
We request read-only access to your fantasy leagues — we can’t change your lineup, make trades, or modify anything. Yahoo uses industry-standard OAuth tokens you can revoke anytime. ESPN credentials are encrypted at rest with AES-256. You stay in control.
In-depth analysis uses 1 credit: lineup optimization, waiver recommendations, trade evaluations, and matchup strategy. Quick factual questions (game times, injury checks, scores) and follow-up questions in the same thread are always free.
No — and that’s by design. Oddsmyth is a co-manager, not an autopilot. It gives you a second opinion with reasoning when you’re torn on a decision, but you still make every call. Think of it like a knowledgeable friend you can bounce ideas off of.
Yahoo Fantasy and ESPN are both fully supported. Yahoo connects via one-click OAuth. ESPN connects through a quick bookmarklet that takes about 30 seconds. Both give Oddsmyth read-only access to your league data.
ChatGPT doesn't know your league. Oddsmyth connects to your Yahoo or ESPN team and answers with your exact roster, opponents, and scoring, using live 2026 stats and projections. It also shows its reasoning and publishes a season-long record of its calls.
No. Oddsmyth advises; you decide. It never makes a lineup change, add, drop, or trade on your behalf.
Yes. Oddsmyth does fantasy football draft prep in chat, and it needs no league connection to start. Ask who to draft at your pick, in your scoring format, and it answers with live 2026 Sleeper ADP and current projections, so it reflects this year's players instead of last year's. You can also connect an ESPN fantasy football league for roster-aware questions. Fantasy baseball stays fully supported on Yahoo and ESPN.
No. Fantasy football draft prep runs with no league connected. Open the chat, tell it your pick and scoring format, and Oddsmyth answers with live 2026 Sleeper ADP and projections. Connecting an ESPN league is optional and adds roster-aware answers.
Yes. Oddsmyth is on the App Store for iPhone, with your daily brief pushed every morning and lineup-lock alerts. It works with the same Yahoo or ESPN league as the web app.
Yes. Oddsmyth Pro builds an optimized DraftKings MLB lineup in chat, with value plays and the reasoning behind each pick. Projections are estimates and ownership is estimated, so it's an edge, not a guarantee.
