The planix AI

AI you can trust.

A chatbot answers. planix works like a team: write, calculate, check – tailored to your industry.

Several models

One AI writes, a second one checks.

Specialised AI models work together and check each other before you see a chapter.

Models check each other.

Financial model

No AI calculates the numbers.

Start-up costs, cash flow and viability come from a financial model with fixed rules. The AI writes the text around them.

Numbers from the financial model.

Your industry

Tailored to your industry.

Benchmarks from official industry data for your country. If your plan deviates strongly, a note with source is added.

Official industry data, per country.

Context

planix remembers your venture.

What you entered in other modules flows in. Nothing is asked twice, nothing contradicts.

Nothing asked twice.

The difference

A chatbot guesses. planix calculates.

The same request for a business plan – two very different results.

Same request, two results.

Rules in detail

Every number in the plan follows a rule you can read up on.

How much money do you need – and where does it come from?

FAQ

Frequently asked questions

Yes, the text – chapter by chapter from your inputs. The numbers are calculated by the planix financial model. That keeps every number traceable.

No. What you do not enter, planix does not calculate. For empty fields the finance board proposes an industry benchmark – it is only calculated once you confirm it.

A chatbot answers single questions. planix guides you through every chapter, calculates with a financial model, compares with official industry data and has several models cross-check. At the end you get a finished document, not a chat history.

Yes. Benchmarks come from official industry data for the UK, and so do tax, wages and National Insurance. Examples from 14 industries show what that looks like.

No. Your inputs are never used to train AI models. Stored in Europe under the UK GDPR.
