Tell the AI what to change and watch your dashboards, charts, and data transform in real time. Every browser on your machine sees the vibe. It's the real thing — just wearing a better outfit.
No staging environments. No seed data scripts. No screenshots in decks. Just your real app, looking exactly how you need it.
Open any web application in Cap Artist Studio. It works with any site — your product, a competitor's, a partner integration. Traffic flows through a local proxy that can intercept and modify responses.
Tell the AI what you want: “boost the revenue metrics”, “populate empty states with realistic data”, “remove the beta badge.” It analyzes the page and generates rules targeting the exact API endpoints, HTML elements, and chart data.
One click routes your system traffic through the proxy. Chrome, Safari, and Firefox all show the customized version. Rules persist through page reloads and navigation — your demo just works.
Cap Artist understands the structure of web apps and rewrites responses at every layer.
Click “Suggest” and the AI analyzes your page, its API responses, and DOM structure to propose targeted enhancements. Accept them with one click.
Rewrite JSON responses at the field level. Replace values, multiply metrics, regex-transform strings, or generate realistic fake data with built-in Faker types.
Target elements with CSS selectors to set text, change attributes, or remove elements entirely. Works on full pages and turbo-stream partials alike.
AI detects embedded chart configurations and rewrites the underlying datasets. Scale up call volumes, populate revenue by channel, fill empty charts with compelling data.
Route your system proxy through Cap Artist and every browser sees the same customized version. Present from Chrome while your prospect follows along in Safari.
Save rulesets to the cloud and share them across your team. Every SE gets the same polished demo environment without manual setup.
SEs, solutions consultants, and anyone who needs a live product to tell the right story.
Swap in the prospect's company name, logo, and industry data across every page. Show them their own world inside your product, not generic sample data.
Trial accounts and sandboxes are always half-empty. Cap Artist fills dashboards with realistic metrics, populates user lists, and brings charts to life.
Load a competitor's public-facing product and annotate it in real time. Highlight gaps, add comparison callouts, or reshape their data to tell your story.
Lock in the exact numbers and content you rehearsed. No more surprises from background jobs, other users, or live data changes during your presentation.
Cap Artist is a native macOS app powered by har-capture-proxy — a high-performance Rust MitM proxy.
The Rust proxy engine decompresses, transforms, and recompresses HTTP responses in a single streaming pass. CSS selectors are matched with Cloudflare's lol_html. Sub-millisecond overhead per response.
Bring your own API key for Gemini, OpenAI, or Anthropic. The AI sees the page HTML, intercepted API responses, and live DOM to generate precise rules. Structured output schemas keep hallucinations in check.
Powered by har-capture-proxy — an open-source Rust MitM proxy engine.
