AI chat for
your website
Turn your documents, website and tools into an intelligent assistant. Upload files or scan your site, embed one script, and let visitors get instant, source-backed answers — around the clock.
- One-line embed
- Files, website & free text
- Your own MCP tools
- OpenAI & Anthropic
Everything you need to answer instantly
Ingest your files, website and free text, connect your own tools, and run on the best of OpenAI and Anthropic — live on your site in minutes.
One Script Embed
Copy one snippet into your <head> and your assistant is live. No SDK, no build step, no backend to maintain.
Your Files Become Answers
Upload PDFs, Word docs and text files. Nubo ingests and indexes them into a searchable knowledge base — automatically.
Website Scan
Point Nubo at your site and it crawls your pages, turning existing content into answers and keeping them in sync.
Write Knowledge Directly
No document to upload? Type answers, policies and FAQs straight into your knowledge base as free text — saved and indexed the moment you hit save.
Bring Your Own MCP Tools
Connect a Model Context Protocol server and your assistant calls your live tools mid-conversation — ticket lookups, order status, internal APIs.
OpenAI & Anthropic
Run on GPT or Claude. Pick a specific model, or let Auto analyze each question and choose the best one for you.
Grounded & Reranked
Retrieval-augmented answers with optional cross-encoder reranking — accurate, source-backed replies and far fewer hallucinations.
Tune the Response Style
Dial from Precise to Creative with a single slider — identical control across OpenAI and Anthropic, no prompt rewriting.
Conversation Analytics
See volume, satisfaction and the topics people actually ask about — with quality scoring built in.
