Chrono Platform

Chrono Platform turns your engineering work into SR&ED claims automatically. Connect your dev tools, and Lucius (our AI) analyzes your activity to draft CRA-compliant documentation. You focus on R&D; Lucius handles the compliance paperwork. SR&ED claims are built on paperwork, not process. Your team solves hard technical problems all year, then scrambles to reconstruct what happened when claim season arrives. Engineers dig through commits and tickets from memory while finance teams piece together timesheets and documentation. Weeks of work, with eligible tax credits left unclaimed and documentation that’s tough to defend in audits. Lucius works in the background as your engineering happens. He analyzes your commits and tickets to spot eligible work, then drafts the technical narratives to match. You keep working the way you always do, and your claim documentation builds itself without the timesheet scramble.
