Sipr

An AI-powered meeting assistant that transforms recorded conversations into organized notes you can actually use. Whether a meeting is uploaded manually or recorded directly from your browser, the platform automatically generates a searchable transcript, a concise summary, and a list of key action items. Instead of listening to an entire recording again, you can search for specific topics or ask questions about the meeting in plain English, and the assistant will provide answers backed by the relevant parts of the conversation. The goal is to help individuals and teams save time, stay organized, and ensure that important decisions and follow-up tasks are never missed.

Ergo

Ergo is a collaborative project management platform that helps teams organize tasks, track progress, and work together more effectively. What started as a simple design prototype evolved into a fully functional application while preserving its clean, modern user experience. The platform allows multiple people to collaborate within shared workspaces, where they can create tasks, break them into subtasks, and discuss work through threaded comments. Team members can be invited to projects, and administrators have the ability to manage access without disrupting ongoing work or losing project history. This ensures that conversations, tasks, and contributions remain intact even as team membership changes. Designed with both individuals and growing teams in mind, Ergo focuses on making collaboration seamless, keeping work organized, and providing a simple yet powerful environment for managing projects from start to finish.
