Your team uses it. But the output comes back generic — not because they’re doing it wrong. Because AI doesn’t know your business.
It doesn’t know:
Your products, services, and packages. What's new, what's retired, what's your bestseller this quarter.
Your regulars, your best buyers, how they like to be handled — the nuance that makes a reply feel like it came from someone who knows them.
Your pricing logic, your process, your tone of voice — the way you handle a complaint, a delay, a negotiation.
So every answer is generic — textbook, written for any business but yours. And they still come back to you.
AI isn’t broken; it just has no context. Meanwhile, competitors who’ve fixed that are pulling ahead every week.
Nucleus is the business context your AI is missing. Spend 30 minutes once — drop your website URL and a few documents — and it builds a structured profile of your business every tool you connect reads from. One source. Same context everywhere. Always current.
One Nucleus, read by every tool you connect.
Before Nucleus
Your sales manager briefs ChatGPT for a proposal to a returning client. The draft comes back generic — wrong tone, wrong products, wrong pricing. She sends it to you to fix. That’s 40 minutes of your morning, gone.
After Nucleus
She asks Claude instead. It already knows your range, your pricing tiers, your tone, and how you treat returning buyers. The draft is 90% there — she tightens it and sends it. You find out when the deal closes.
That’s what Nucleus does. Not in theory. In practice.
Six areas, built from your website and docs — the business knowledge every connected tool reads before it answers. You read, edit, and approve every word.
Who you are — your story, what you stand for, and how you sound.
What you sell — products, services, packages, and how you price them.
Who buys from you — your best customers and what they care about.
How you run — your process, standards, and how you handle the hard cases.
Where you’re headed — your priorities and what you’re building toward.
Your quick-reference tools — templates, scripts, and standard responses.
Not a knowledge base you maintain. A living profile that grows with your business.
Uploading files to ChatGPT or building a custom GPT was built for people who want to build — not for owners who need it to just work.
Built for owners, not engineers. You run the business, not a dev team. Nothing to wire up, no agents to configure, no stack to connect — it works the way you already work.
Starts from your website, not your data warehouse. Most tools need your systems plugged in and your data clean first. Nucleus needs a URL. Drop your site and it builds itself.
| Comparison dimension | Built-in knowledge (ChatGPT Projects, custom GPTs, Claude Projects) | Nucleus |
|---|---|---|
| Getting started | You upload and organize the files yourself, in each project | Drop a URL and a few docs — we build the structured context for you |
| Where it lives | Siloed per project, per tool, per vendor | One source of truth, read by every tool you connect |
| Structure | A pile of uploaded files | Structured into the five areas that run your business, every fact traced to your source |
| Staying current | You re-upload when things change | Edit once — every connected tool picks it up |
| Across tools | Re-create it in ChatGPT, then again in Claude, then again in Cursor | One connection, the same context everywhere (over MCP) |
Built-in features change — we keep this comparison current.
Keep using ChatGPT, Claude, and Cursor exactly as you do. Connect them to Nucleus once, and every one of them answers like it works at your company.
Build my Nucleus — freeStep 1 · Build
Drop your website URL and any docs you have — pricing, SOPs, product lists. Nucleus reads them and organises everything into six areas. Done in under an hour.
Step 2 · Connect
Connect the AI tools you already use — Claude, ChatGPT, Cursor. From then on, every tool reads your profile before it answers. No prompts, no copy-paste.
Step 3 · Update
Something changes? Update Nucleus once, and every connected tool reflects it. One source, not six.
You get useful answers because you know your business — your team doesn’t, so they come back to you. Invite them, and their AI reads the same profile: your ops lead drafts on-brand supplier emails, your sales rep handles objections your way, your new hire is useful from week one. You stop being the one everyone routes through.
How it works
One source of truth for the whole team — not five people guessing in five different chats.
Built by operators who ran owner-led businesses before building AI tools for them — so Nucleus is sharp because it’s specific. Here’s the honest fit.
For you, if
Not for you, if
Yes — and it stays yours entirely. Your Nucleus is a private database only you and your invited team can access. It's never shared with other businesses, never used to train AI models, and never visible to us beyond what's needed to run the service. What goes in stays yours.
Any business where the owner holds most of the knowledge and a team needs AI to get work done. Retail, professional services, agencies, restaurants, trading, salons, clinics, consultancies, manufacturers — if you have customers, a team, and a way you run things, Nucleus works for you. The industry doesn’t matter; the owner-bottleneck problem is universal.
Yes. If you can paste a URL into a browser and answer questions about how your business works, you can set up Nucleus. Most owners finish their first version in under an hour — you fill in what you know, skip what you don’t have yet, and refine over time.
You update Nucleus — one section, one field, or a whole area. Every AI tool connected to your Nucleus reflects the update immediately. You don’t touch each tool individually. You have one source. That’s the point.
Nucleus works with the AI tools you already use — Claude, ChatGPT, Cursor, and others. You don’t replace anything; you connect Nucleus to what you have and those tools get smarter. If you’re not using any AI tools yet, start with Claude or ChatGPT first, then come back when you’re ready to go deeper.
Set it up in under an hour. It runs quietly in the background after that — better answers for your team every day, without you in the middle.
Worst case, you’ve lost an hour. Best case, you’ve changed how your whole team works.
