Capabilities

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.

In your dashboard

Manage your assistant in one place

Every source, setting and metric behind your assistant lives in one dashboard — designed so a non-engineer can ship changes in a few clicks.

See how your assistant is performing
Sessions, messages, tokens and latency — with a launch checklist that walks you from an empty project to a live assistant.
Upload, crawl or type — your assistant learns from all of it
PDFs, websites and free text sit in one place. Every source shows its indexing status, and you can rebuild, rescan or delete without touching code.
Drill down by model, time range and metric
Messages, tokens, conversations and average tokens-per-message. Filter by any model, switch granularity, export to CSV — the deep view your finance team will ask for.
Prove a change made your assistant better
Keep a set of the questions you care about, re-run it after every change, and watch the trend. Markers name what moved between runs — so a drop reads as “reranking went off” rather than a mystery.
Tune the assistant without touching your code
Point Nubo at your host, write a system prompt, pick a model — or leave it on Auto — and dial response style from Precise to Creative with a single slider.
