The problem

You're basically paying rent
to seven different AIs.

AI for email. AI for documents. AI for PDFs. AI for spreadsheets. Each one siloed, expensive, and completely unaware of everything else you've got going on.

AI for Docs $20/mo
AI for Spreadsheets $30/mo
AI for PDFs $15/mo
AI for Browser $10/mo
AI for Research $25/mo

Imagine if...

What if AI just worked?

Imagine if
Writing a full donor report took an afternoon, not two weeks.
Upload the funder's template, your past reports, org profile, and results data. Then open the blank proposal — select each section heading, hit Ctrl+D, and Cruxi fills it from everything you uploaded. Section by section. Done.
✓ Context drafting
Imagine if
You never had to explain your organisation to AI again.
Upload your org profile, strategy documents, and policies once. Switch to that context any time. Cruxi already knows who you are, what you do, and how you work — permanently.
✓ Permanent memory
Imagine if
Your company's full knowledge base was two keystrokes away.
Reading a vendor contract in Chrome? Hit your shortcut, switch to "Legal" context, ask "does this contradict our standard terms?" — answered instantly, from your actual legal documents.

Every email, reply, and message sounded exactly right.
Select any text in Gmail, Outlook, or Slack. Click Polish, Shorten, or Make Formal. Cruxi rewrites it in context — no more agonising over tone. Works in every app, instantly.

Imagine if
Dense data sheets and technical specs explained in plain English.
Highlight any table, spec section, or wall of numbers in a PDF or spreadsheet. Click Explain. Cruxi breaks it down clearly — no more pretending you understood the supplier's data sheet.
✓ Explain mode
Imagine if
One AI that switches between expert domains in one click.
Grant Writing. Legal Review. HR Queries. Product Docs. Each is a named context with its own uploaded documents. Same toolbar, same shortcut — just a different brain loaded up and ready.

Why Cruxi

Everything else is
trapped in a tab.

ChatGPT lives in a browser. Copilot only works in Microsoft apps. Per-app AI only knows that one app. Cruxi goes everywhere with you.

What people say

Real people. Real results.

★★★★★

I cancelled four AI subscriptions the day I installed Cruxi. I don't miss them. Not even a little bit.

★★★★★

The drafting mode is genuinely unreal. I select a section, hit Ctrl+D, and it writes something I'd normally spend an hour on. From MY documents.

Grant Writer
★★★★★

I uploaded our entire HR handbook once. Now every time a policy question comes up in a meeting, I just ask Cruxi. Two seconds. Correct answer. Every time.
