Everything you need to run accurate AI
From crawling to embedding to live chat — the entire pipeline in one platform.
Automatic site crawling
Add your URL and we crawl every page, extracting clean content and keeping it fresh automatically.
Semantic vector search
Every page is chunked and embedded with OpenAI. Queries run semantic search to find the most relevant content.
AI accuracy scoring
After each crawl, automated Q&A tests score your chatbot 1–5. Know exactly how accurate it is.
Embeddable chat widget
One script tag adds a branded AI chat widget to any website — no backend coding required.
Query analytics
See what visitors ask, answer rates, latency, and which questions go unanswered.
API access
Query your knowledge base programmatically with secure API keys. Integrate into any stack.
Auto re-crawl
Set weekly or monthly re-crawls so your AI stays up to date as your website changes.
LLMs.txt generation
Auto-generates a machine-readable llms.txt summary of your site for AI crawlers like ChatGPT.
