Evidence, proof and selling tools for NexusMind

Level 1 Beginner: understand it

Agents record facts with sources. Two different answers to a one-answer question are flagged.

Think of it like this: A shared company address book that refuses to silently replace a phone number: it shows you both and who supplied each.

Read the full plain-English explanation: NexusMind, explained.

• I read the explanation above.
• I can say what it does in one sentence, without notes.

Level 2 User: see it work

Run it live: open the live demo. Before each result, guess what will happen. These are checks it must pass:

• First fact: CEO is Dana Lee (press release): Nothing to contradict yet.
• Second fact: CEO is Sam Ortiz (scraped blog): A different CEO for the same company is flagged.
• Is the first fact still there?: Nothing is overwritten; the original fact is kept and shown.
• Where did the doubtful fact come from?: Every fact keeps its source.

• I ran the live demo.
• I can explain what one of these checks shows.

Level 3 Verifier: prove it yourself

This is the skill that sets you apart: you don't have to believe us, and neither do your customers.

1. Install Python 3 if you don't have it (python.org/downloads).
2. Download the kit and unzip it.
3. Open a terminal in that folder. On Windows, click the folder's address bar, type cmd and press Enter. On a Mac, right-click the folder and choose New Terminal at Folder.
4. Run python3 verify.py (on Windows, python verify.py). It checks the seal without the internet.
5. Run python3 verify.py --live. It repeats every check from your own computer.
6. Try to cheat it: open transcript.json in a text editor, change one character, save, and run python3 verify.py again. It must now say FAIL. Unzip a fresh copy afterward.

• I ran the kit's check on my own computer.
• I changed a file and saw it fail.

Level 4 Expert: know the edges

An expert knows what a product does not do, and says it first. That is what makes a buyer trust you.

• It flags contradictions only for facts you declare as one-value-only; it does not understand meaning.
• It does not decide which fact is true; it shows both with their sources.
• Facts are only as good as what agents record.

You can say

• Every fact keeps its source.
• Contradictions are flagged, never silently overwritten.

Never say

• "Knows which fact is true".
• "Understands meaning".

Read the questions real buyers send, with honest answers: answers to buyer questions.

Test yourself (click a question to see the answer)

• I got every quiz question right without looking.
• I can name one thing it does not do.
• I explained it to a friend, and they understood it.

Level 5 Seller: put it in front of a customer

1. Copy, paste, send: the shortest route, no technical skill needed.
2. Who buys it and where to find them.
3. The sales conversation, then the offer and the close.
4. The rules: read these before your first message.
5. Selling tools with this product's evidence built in: pitch, emails, call script, objection answers, one-pager.

• I read the rules.
• I sent my first personal message.
