The Opportunity

Problem

Distributed remote teams distrust AI task managers that store sensitive work data in the cloud, risking privacy breaches and collaboration breakdowns.

Solution

StealthTask runs AI-powered task prioritization and suggestions entirely in your browser using local ML models, ensuring no sensitive data ever leaves your device. Teams sync tasks via end-to-end encrypted channels for seamless collaboration without privacy risks. Restore from encrypted backups anytime for total control.

Target Audience

Distributed remote teams using AI-powered task managers to handle sensitive work data such as client details and project schedules.

Differentiator

100% browser-based AI processing with zero server-side data access, unlike cloud AI tools that scan your data.
