Help me compare these vendors for [PURPOSE]:

[VENDOR NAMES AND KEY FACTS]

Ask me what matters most, propose 8 weighted criteria, build a scoring table, calculate weighted scores, point out where the data is weak and suggest three questions to ask each vendor before deciding.

Agree the criteria and weights before you look at any vendor's scores.

What you will get

Eight weighted criteria agreed with you, a scoring table with weighted totals for each vendor, a note on where the data is thin, and three questions to put to every vendor before you decide.

Common mistake

The AI scores vendors on facts it does not have.

Fix: Paste the real details you have, such as price, terms and features, and say “mark unknown as unknown, do not guess a score”.

Also watch for

The weights seem to favour your preferred vendor. Agree the weights first and only then share scores. Ask “would the ranking change if price counted double?” to test it.
The criteria are too broad, like “quality”. Ask for criteria that can be checked, such as “response time under a day” or “can export my data”, with a one-line test for each.

Try a variation: add a risk column

Add “a separate risk score for lock-in, hidden costs and how hard it is to leave”, shown beside the main score. A vendor that wins narrowly but is hard to leave may not be the best choice.

Still not right? Reply with this

Lock these weights. Now score each vendor from my notes only, mark gaps as unknown, and show the total with and without the gaps.
