Overview
Hush is an open-source noise suppression model developed by weya AI. It removes background noise, competing voices, and audio interference from real-time calls, ensuring that voice AI agents hear only what matters. Hush is lightweight (8 MB), processes audio frames in under 1 ms on CPU, and is trained on over 10,000 hours of real-world noisy audio. It is designed for Voice AI developers, call centers, and BFSI teams.
Stride is an AI-native software delivery OS that replaces seven tools (Jira, Confluence, Miro, TestRail, etc.) with one connected workspace. It uses a single graph to link stories, diagrams, processes, tests, defects, and releases. Stride's AI generates stories, acceptance criteria, architecture options, and test cases from your project context. It integrates with Claude Code and Codex via MCP, enabling AI agents to work directly on your backlog. Stride is aimed at engineering teams, product managers, QA, and designers.

Pricing
Hush is completely free and open-source. The company offers a 2-week pilot for enterprise customers to evaluate the model in their workflow before full rollout. There are no licensing fees or per-seat costs.
Stride operates on a subscription model. Basic features start at $9 per seat per month, but most teams opt for Stride Pro at $29 per seat per month, which includes all modules (Plan, Design, Optimize, Verify) and full AI capabilities. A free trial is available, and the company provides an ROI calculator to estimate savings from tool consolidation.
