WorkSignal is a complete hiring platform designed for a world where both recruiters and candidates use AI. It replaces traditional ATS tools with a system built for modern hiring workflows, including custom pipelines, candidate management, and team collaboration. One of its core features is AI voice screening, which conducts structured phone interviews and returns transcripts, scoring, and authenticity analysis to detect AI-assisted responses. The platform also offers X-native sourcing, allowing recruiters to post jobs on X (Twitter), capture replies as candidates, enrich profiles with GitHub and portfolio data, and initiate outreach via direct messages. WorkSignal includes a compliance engine covering multiple global regulations such as GDPR and CCPA, ensuring auditability and safe hiring practices. For developers, it provides a REST API and MCP server for integration with tools like Claude Code and Cursor. The platform integrates with common tools like Google Calendar and Slack, making it a flexible and scalable hiring solution for modern teams.
