Questions? We've got answers.
Under 2 minutes. Connect your inbox provider via secure OAuth (one click), and StopLight immediately begins classifying your emails. No manual configuration required—our AI starts learning your preferences from day one.
StopLight works with Gmail (via OAuth2), Microsoft Outlook (via Microsoft Graph), and Yahoo Mail (via IMAP). We're continually expanding support for additional providers.
Privacy is foundational to StopLight. We use OAuth 2.0—which means we never see or store your email password. Email content is processed for classification and immediately discarded. Only metadata and AI-generated summaries are retained. We also automatically scrub personal information (PII) before any AI processing.
StopLight achieves 99% classification accuracy using a two-prompt GPT-4o-mini pipeline. But it gets even better—our self-learning system adapts over a 30-day period, adjusting classification weights based on your behavior: how you reply, archive, and prioritize.
StopLight is for anyone overwhelmed by email volume—busy professionals, academics, team managers, freelancers, and individuals. If you receive more than 30 emails a day and want clarity without effort, StopLight is built for you.
Absolutely. Pro and Ultimate plans include custom priority rules, letting you define VIP senders, keyword triggers, and domain-based overrides. Plus, the AI naturally learns from your reclassification actions and adjusts automatically.
