Use Charts with AI

Ask Claude or ChatGPT about any team, player, or number on this site. Free, no sign-in.

Charts has a connector, so an AI app can look things up here directly instead of guessing. Add it once, then ask in plain English. It answers from the same numbers as these pages: team ratings and ranks, the player board, run values, park factors, and the glossary.

It is free and asks for no account. This is the address the app needs:

Connect it

Claude

Open Settings, then Connectors, then Add custom connector. This works on any plan; the free plan allows one custom connector.
Paste the address above and save. There is nothing to sign in to.

ChatGPT

On the web, go to chatgpt.com/plugins, press Add, then Add custom MCP server.
Name it, paste the address above as the Server URL, and set Authentication to none: this connector has no sign-in.
Check I understand and want to continue, then create it.
If your Plugins page has no Add custom MCP server, your plan cannot add one yet. Claude's free plan can.

Anything else that speaks MCP

Gemini's custom apps, Claude Code, Gemini CLI, and other MCP clients take the same address. It is a standard Streamable HTTP server with no authentication.

Things to ask

Who led the SEC in wRC+ this season?

How good was Texas's pitching, and where did it rank?

What is a walk worth next to a single in college softball?

Is it worth bunting with a runner on first and nobody out?

Which Division I fields boost scoring the most?

Explain wOBA in plain words, then show me the top ten.

What to know

It is the finished 2026 season, not a live feed, and it covers Division I only.
Two kinds of numbers come back, labeled: official NCAA season totals (records, a player's season line) and our own metrics (ratings, wOBA, wRC+, WAR, FIP, odds).
Every answer comes from the files these pages are built from, so the app and the site cannot disagree. Ask it for the page link and check for yourself.
The connector asks for no account, and it records only which tool was called, not who called it or what was asked.

The 15 things it can do

Find a team by nameLook up NCAA Division I softball teams by any part of the name. Returns each match's conference, official record, composite rank, and page.
Team profileOne Division I softball team's 2026 season: official record, composite rank nationally and in its conference, 24 metrics each with a national and conference rank (ratings, WAR, offense, run prevention, style), offensive identity, park factor, and its bracket simulation odds if it made the tournament.
Rank teams by a metricDivision I softball teams in order on one metric, nationally or within a conference. The default metric is the composite rating, the site's main ranking.
Division I conferencesThe Division I softball conferences with how many teams each has and its top team by composite rating.
Find a player by nameSearch the Division I softball player board by any part of a player's name, optionally within one team. Returns each match's team, class year, position, and a short season line.
Player season lineOne Division I softball player's 2026 season: the official NCAA hitting line, pitching line, or both, plus Pioneer Pennant's wOBA, wRC+, WAR, WPA, and FIP, and where her rates sit as percentiles among Division I players.
Hitting leaderboardDivision I softball hitters ranked on one stat, nationally or within a conference or team. Rate stats start from a 100 at-bat minimum unless you set another.
Pitching leaderboardDivision I softball pitchers ranked on one stat, nationally or within a conference or team. Rate stats start from a 150 batters-faced minimum unless you set another.
Run values and league baselinesWhat each event is worth in college softball: the run value and wOBA weight of a walk, hit by pitch, single, double, triple, and home run, the value of a steal and its break-even rate, league baselines, runs per win, and the softball-native FIP weights.
Run expectancy by base-out stateExpected runs and the chance of scoring at least once from each of the 24 base-out states in college softball, plus what a successful sacrifice bunt costs and the success rate a steal needs to break even.
Park factorsHow much each Division I softball home field raises or lowers scoring. With a team, that field's factor; without one, the most hitter-friendly and most pitcher-friendly fields.
Bracket simulation oddsThe 2026 NCAA tournament field's simulated chances of reaching the super regionals, the Women's College World Series, the final, and the title, best title odds first.
What the season's data showedThe measured findings from the 2026 Division I season: how hitters do each time through the order, which offensive traits produce runs, what bunting and stealing are worth, and whether an unusual style pays.
GlossaryA softball analytics term in plain words and in technical ones (wOBA, wRC+, WAR, FIP, SRS, run expectancy, park factor, and the rest). With no term, lists every term by group.
