How it works

Four stations, start to run sheet.

01

Describe

Tell it what you want to find out.

You write your goal in plain words and list what you can change.

  • goal in plain english
  • no statistics to choose
02

Define

Say what you can change.

A range you can set anywhere in, a few fixed settings, or a set of options.

  • temperature 20 to 80 °C
  • stirrer 200 / 400 / 600 rpm
  • catalyst A or B
03

Design

It picks the design and explains why.

The design that fits your variables and your budget of runs, with the reasoning written out.

  • full factorial
  • d-optimal
  • explained in plain english
04

Record

Run the sheet, type the results in.

Results stay attached to the runs that produced them.

  • export to excel
  • upload results back
  • saved to your account
What it does

Built for people who have to defend the plan.

F.01

You get a run sheet, not a wall of text.

A numbered list of experiments you can print and work from in the lab that afternoon - and a record of exactly what you ran, so you can show your working later.

F.02

Every term is explained.

Statistical language appears with a plain English definition on hover, so you can defend the design to a supervisor.

F.03

Your work is saved.

Run sheets and results live in your account, not in your browser, so they survive a different machine.

Pricing

Designing experiments is free.

Analysis of your results is the only thing that will ever be paid for.

Questions

Frequently asked questions

Do I need to understand statistics to use this?

No. You describe your experiment in normal words. There are no statistical terms to choose from, and where one appears in the explanation, hover over it for a plain English definition.

How is this different from asking ChatGPT?

A chatbot can design an experiment, and often does it well. What it cannot do is hand you a numbered run sheet to work from, or remember any of it next week. ExperimentIQ keeps the design, the runs and the results together, so months later you can still show what you ran and why - same experiment, different machine.

What does it cost?

Designing experiments, generating run sheets and recording results are free. Analysis of your results will be £19 a month when it launches. See pricing above.

Who can see my experiments?

Only you. Experiments are tied to your account and access is enforced at the database, not just in the interface.
