Draft Sonar — Live Draft Assistant for Yahoo

Read-only Yahoo fantasy draft companion: live pick tracking, tier alerts, and pick recommendations. Never drafts for you.

Reads the board. Never touches it. Draft Sonar watches your Yahoo fantasy football draft live and shows you what the board is really doing — who survives to your next pick, which tier is about to collapse, and when a run is on. You make every pick yourself, in Yahoo's own UI. Draft Sonar has no draft button, by design. ZERO SETUP. Open your draft room and the overlay appears, already configured: league size, your slot, roster shape, and scoring — detected from the page itself. Superflex/2QB leagues automatically run on real 2QB market ADP. TE-premium and 6-pt-passing scoring are detected too, with manual overrides if you want them. LIVE, AND HONEST ABOUT IT. Every recommendation shows survival odds to your next pick, learned from how your room drafts. Tier alerts ("Last Tier-2 TE on the board"), run detection, bye-week context, and value flags — computed on your machine, updated within a second of every pick. BUILT TO SURVIVE A REAL DRAFT. Page reload? Installed mid-draft? The board reconstructs from Yahoo's own pick grid and self-heals every 60 seconds. In our full-draft audit it tracked 180 of 180 picks with zero errors against Yahoo's official results. A REAL FINISH. When the draft ends: a letter grade computed against the other teams in your actual league, the takeaways behind it, a season outlook, and one-click roster export. PRIVATE BY ARCHITECTURE. No account, no sign-up, no analytics. Your picks never leave your browser. The extension reads only the draft page and fetches one public file: the daily player dataset (ADP, tiers, injury facts from public sources). It never touches your Yahoo credentials or auth tokens. Full policy: draftsonar.com/privacy Free for unlimited drafts. Snake drafts only for now — auction rooms are detected and politely declined rather than misread. Not affiliated with Yahoo.
