What is The Playbook?

Three steps. Zero noise.

When you sign up, you pick the teams you care about across any combination of supported leagues. There are no required picks and no league bundles — a Manchester United fan who also follows the New York Rangers and Boston Red Sox can build that exact mix.

Every morning, an automated pipeline fetches live data from public sports APIs (ESPN, official league feeds), composes a per-team brief using a large language model, runs the result through a two-dozen-plus-rule fact-check validator, and assembles a personalized broadsheet email that lands in your inbox by 6 AM ET. One subscriber. One email. Only their teams.

Personalization beats personalization-by-section.

Most "personalized" sports newsletters let you pick a section preference (e.g. NFL-heavy or NBA-heavy) but still deliver league-wide content. The Playbook is granular at the team level: if you follow only Liverpool and the Jacksonville Jaguars, you get one section about Liverpool and one about the Jaguars — nothing else. No Manchester City news, no Buffalo Bills coverage, no PGA filler.

Hallucination defenses.

AI-generated sports coverage is famously prone to factual errors — wrong scores, players assigned to old teams, fabricated stats. Every brief from The Playbook passes a validation cage of two dozen-plus fact-check rules before it's cleared to send. It catches transferred players (a driver still listed at a team he's left), score and standings mismatches, fabricated advanced stats, impossible game states, and stale-season references, and it cross-checks the day's headline result against an independent web source. Critical violations trigger an automatic re-prompt; if a factual leak survives the retry, the offending sentence is redacted from the email before delivery — the send is never held hostage to a single bad line.

Newspaper-style design.

Every issue is rendered as a single-email broadsheet with named sections by sport: The Red Report for Manchester United, The Tifosi Report for Ferrari, The Papaya Report for McLaren, The Silver Arrows Report for Mercedes-AMG, The Tour Report for PGA Tour. The lead story — an extended brief at the top of the broadsheet — is auto-selected each day based on which of your teams has the most newsworthy moment.

We publish the paper — and grade our own calls.

Every edition is also posted, in full, to The Archive — a public, name-free record of every day's paper you can flip through like a real newspaper, back through the days. And every morning the desk makes one falsifiable call. Every call goes on The Ledger the moment it's written, then gets graded against the actual result — hits and misses both, permanently, nothing deleted. Most tipsters quietly forget the calls that missed. We don't.
