Oddsmyth

Oddsmyth connects to a Yahoo or ESPN fantasy baseball league in a single OAuth step, imports your roster, standings, and scoring settings, and then functions as a chat-based co-manager. You ask it a question — should I start this pitcher against Colorado? is this trade fair? — and it returns a take with explicit reasoning, citing which data source drove the recommendation. The vendor states data comes from the MLB Stats API for live stats, FanGraphs Steamer for rest-of-season projections, and Baseball Savant for Statcast metrics including xwOBA, barrel rate, and exit velocity. Every in-depth analysis costs one credit; quick factual lookups and follow-up questions in the same thread do not.

The credit model is the practical differentiator. There is no subscription clock running: credits do not expire, and the free daily brief arrives every game-day morning at 9am regardless of credit balance. That brief is two lines — who starts, who sits, one action item — which means you get a daily floor of utility without spending anything. The weekly Monday report card summarizing record, standings, and top performer is also free.

The tool is deliberately not an autopilot. The vendor describes it as a co-manager rather than an agent: it offers reasoning and a take, but it cannot touch your lineup, submit waiver claims, or execute trades. Read-only access is enforced by design, and Yahoo credentials use OAuth tokens you can revoke independently. ESPN credentials are encrypted at rest. The friction this creates is intentional — you stay accountable for every move — but it also means the tool adds no value if your goal is hands-off automation.

Platform support is limited to Yahoo and ESPN. Managers on Sleeper, NFBC, Fantrax, or custom-hosted leagues can access a Draft Prep mode that delivers player rankings, ADP analysis, and Statcast scouting without a league connection, but the roster-aware, matchup-specific analysis that defines the core product is not available outside the two supported platforms.
