LexSort Legal is a local-first case management tool built specifically for Ontario criminal defence lawyers. Everything — client communications, disclosure documents, matter files, AI-assisted extraction — runs entirely on the lawyer's own machine. Nothing goes to the cloud. Criminal defence practice involves some of the most sensitive material in law: unredacted Crown disclosure, wiretap transcripts, informant records, and constant client communication under real time pressure. Commercial cloud AI tools require uploading this material to third-party servers, which creates real confidentiality and Law Society of Ontario compliance risk. LexSort was built as the alternative: a sovereign, on-device workstation where AI helps organize and surface information, but every suggested action requires the lawyer's explicit review before it's committed — human-in-the-loop by design, not an autonomous agent making decisions unsupervised. We're an early-stage, pre-revenue company, and we're upfront about that. We're working with a practicing Ontario criminal defence lawyer for product development and feedback, and in active hands-on co-design with a law student testing the application directly. We have a native desktop application for macOS, verified end-to-end on a clean install, with a Windows version in active development. If you care about building software that handles real stakes — where a missed detail has real consequences for someone's liberty, not just a business metric — this is that kind of work.

Hey there! We're the Eolas team. We build software that helps multifamily property teams operate with better visibility, faster response times, and fewer preventable incidents. Today, most physical operations rely on fragmented tools and manual processes. Important signals exist, but they’re often scattered across systems, surfaced too late, or buried in noise. This makes it harder for teams to stay ahead of issues and respond effectively when something goes wrong. We’re building a platform that brings these signals together and turns them into clear, actionable information. The goal is simple: help operators understand what’s happening in real time and give them the tools to respond quickly and confidently. Behind the scenes, this requires building reliable, always-on software that can operate at scale and perform consistently in real-world environments. We care deeply about creating systems that are dependable, intuitive, and built to last. We’re an early team that cares deeply about building thoughtful, reliable software. Everyone here has a voice, and the work you do will directly shape what Eolas becomes!
