Does your Boolean actually parse?
Paste any sourcing string. Seven deterministic checks catch the syntax mistakes that silently zero out ATS and X-Ray results — then hand you a fixed string to copy.

ResultRule-based checks · no AI
Paste a Boolean string and run the linter. Seven deterministic checks — quoting, operators, OR grouping, nesting, dialect, scope, exclusions — plus a conservative auto-fix.
Free · no login · 30 checks/day per network. Rule-based only — it catches syntax, not sourcing quality. Generate full strings in the workspace or learn the dialects in the Boolean search guide.
