Brand tone analyser
Paste any public website URL. We scrape the copy with Firecrawl, ask Claude what the brand sounds like, and return three things: a verdict, a few tone descriptors, and one direct suggestion for what would land better.
How does this work?
When you submit a URL, the form posts to /api/playground/tone. That route scrapes the page’s main content with Firecrawl, hands the markdown to Claude Sonnet 4.5 with a strict-JSON system prompt, and returns the parsed result.
The whole round trip is usually 8-15 seconds. No data is stored. The same pattern (scrape + LLM analysis + structured output) sits behind production tools we ship for clients — pointed at their CRM, their product copy, or their competitors.
