Chordio
ActiveClaude Code design workspace built for product teams
About
Designers and product managers are often locked out of prototyping on top of their existing product. Security policies, large code base, and complex build setup all stand between the promise of code-first front-end design and reality. The Chordio Workbench helps non-technical team members prototype new experiences on top of their existing products even when they don’t have access to the source code. The full workflow runs in Claude Code on your local machine. It starts with cloning the front-end of the product into the workbench repository directly from the browser and compiling it into code a coding agent can work with. This means anyone can start prototyping in minutes without having to worry about a complex environment setup. The Workbench includes agent skills to help ensure prototypes meet team standards, are backed by research, and presented to stakeholders with clarity.
From their website
chordio.com ↗Chordio offers PX-bench, a product experience benchmarking tool that evaluates how coding agents design product experiences within real apps, covering design, UX, accessibility, performance, and correctness. It measures agent-driven frontend design decisions in held-out host applications using a defined rubric and independent audit.
PX-bench is a capability evaluation framework applied to product experience. It runs agent-generated feature work inside a held-out multi-screen host app, scoring across eight product-experience categories (intent fidelity, product fit, visual craft, convention adherence, pathway completeness, content language, resilience, accessibility). Scoring combines automated checks (axe-core, structural-diff) and human judgment by senior product designers, with an independent audit. Runs are conducted using a protected brief, a sealed environment, and an independent scoring process via Inspect AI; results are published with a known-ground-truth for evaluation. Private PX-bench evaluations can be run for clients to obtain a complete scored report.
Who it’s for: Product teams and organizations developing or evaluating coding agents for frontend product design and feature implementation, especially those integrating AI agents into existing apps.
- held-out host app evaluation
- eight-category product experience scoring
- automatic scoring with human designer review
- integration of accessibility and UX rubrics

- private PX-bench runs for clients
Funding mentions (Y Combinator) and publication of methodology; public/private evaluation runs available, emphasis on benchmark development and independent auditing
Founders · 2
I'm the co-founder and CEO of Chordio. From 2014-2017 I was a co-founder and CEO of Brand.ai, where we built a platform that solved problems of design at scale at the enterprise. In 2015 Brand.ai participated in the Techstars accelerator and raised financing from amazing investors. It was acquired by InVision in 2017. From 2017-2022 I helped build Brand.ai into InVision DSM, InVision's second commercial product.
Co-founder and CTO - Chordio. Previously co-founded Brand.ai - a platform for design system management. Sold to InVision in 2017, and stayed on as an engineering manager and director of engineering. Continued to scale and evolve the product into InVision's DSM (Design System Manager). Moved on in 2022 to lean into the project management space, where I see many familiar patterns and challenges waiting to be solved.
Launch
Planning made easy. Accurately reflect workload and give everyone a voice to quickly align on a plan forward.
Chordio builds a lightweight, collaborative planning tool for teams to manage upfront planning, prioritization, estimation, and capacity, with planning boards and a capacity-based sprint view. It supports evolving from casual brainstorming to official plans and exports to Jira or other issue trackers; design partners are invited to pilot the next release.
