1

Open any web app

Browse to your product in Cap Artist Studio. Traffic flows through a local proxy — every response can be intercepted and rewritten.

2

AI suggests enhancements

Click “Suggest” and the AI analyzes the page structure, then proposes targeted changes — headings, copy, CTAs, data.

3

Review & accept rules

Each generated rule shows exactly what it targets. Accept all, cherry-pick, or discard. You're always in control.

4

Share it live

Rules apply instantly across every browser. Share a viewer link and the prospect gets full interactive access to the customized product in a secure cloud browser — no installs needed.

🔨 capabilities

way more than find-and-replace

Cap Artist understands the structure of web apps and rewrites responses at every layer.

✨

AI Rule Generation

Click “Suggest” and the AI analyzes your page, its API responses, and DOM structure to propose targeted enhancements. Accept them with one click.

⚙

JSON API Mutations

Rewrite JSON responses at the field level. Replace values, multiply metrics, regex-transform strings, or generate realistic fake data with built-in Faker types.

📄

HTML Transforms

Target elements with CSS selectors to set text, change attributes, or remove elements entirely. Works on full pages and turbo-stream partials alike.

📊

Chart Data Rewriting

AI detects embedded chart configurations and rewrites the underlying datasets. Scale up call volumes, populate revenue by channel, fill empty charts with compelling data.

🎬

Live Viewer Sessions

Send a link — the prospect gets full interactive access to a real, logged-in account running in a secure cloud browser. They click, navigate, and explore freely. Your credentials stay completely hidden.

🚫

URL Blocking

Control what the prospect can access. Block admin panels, billing pages, or internal APIs with regex patterns. The AI can generate them for you. Team owners can lock rules so nobody disables them.

🎮

Guided Demo Mode

Build step-by-step walkthroughs with overlays, spotlights, driven actions, and 40+ cinematic transitions. Prospects follow the guided flow or go off-script to explore freely — a “Return to Demo” button always brings them back.

🌍

Cross-Site Demos

Build demos that span multiple websites and products. Walk a prospect from your marketing site through signup into your dashboard, or connect your app with third-party integrations — all in one seamless guided flow with transitions between every page.

🌐

Cross-Browser Support

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.

📦

Team Sync

Save rulesets to the cloud and share them across your team. Lock blocked paths so members can't accidentally toggle them. Full version history with one-click restore.

🎯 built for

every demo scenario fr

SEs, solutions consultants, and anyone who needs a live product to tell the right story.

Personalized prospect demos

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.

Empty state recovery

Trial accounts and sandboxes are always half-empty. Cap Artist fills dashboards with realistic metrics, populates user lists, and brings charts to life.

Competitive teardowns

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.

Conference and webinar demos

Lock in the exact numbers and content you rehearsed. No more surprises from background jobs, other users, or live data changes during your presentation.

Multi-product & integration demos

Demo interconnected systems that span multiple websites. Walk through your CRM, then seamlessly transition into a partner’s platform, a third-party integration, or a different product tier — all in one guided flow, all with real logins and live data.

Leave-behind demo access

Send the prospect a link to explore your product on their own time — fully logged in, fully customized, fully interactive. They experience the real product with their data, not a recording or a slide deck.

⚡ under the hood

powered by a Rust proxy engine

Cap Artist is a native macOS app powered by har-capture-proxy — a high-performance Rust MitM proxy.

Wire-speed rewriting

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.

Multi-model AI

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.

Secure cloud browser

Each viewer session runs in an isolated cloud VM with a full browser. The prospect clicks, navigates, and explores freely — but your credentials never leave the server. Edit rules in Studio and the session updates in seconds.

Powered by har-capture-proxy — an open-source Rust MitM proxy engine.
