The best of AI, all in one place

We asked ourselves: what does the best AI in the world look like?

You could move from model to model to get the results you want. Your data would never be used for training. And you’d only ever pay for what you used.

That sounded great – so we made it. Welcome to Definition AI.

There’s no need to pit artificial intelligence against the real thing. We match the best of what AI can do with expertise that can only come from people.

Our writers, designers, strategists and video producers test out and recommend different models for different tasks. And you get them all in one place with one login.

Pricing

We want you to get the most out of the best AI in the world. To do that, we realised it’s usually far more cost-effective to pay for what you use, not the number of users. (Work out your savings here)

So we have a modular pricing system to help you do just that.

There’s a one-off fee so we can set up your private environment and give you secure access.

After that, you’ll pay for three things monthly:

a small fee for us to host it
the model bundles you pick
costs based on how much you use it

“The tone of voice guidance and prompt support has gone down a storm. We’ve been sharing the prompt you wrote for us far and wide internally. I know for a fact a lot of people are using it to help with content – including our brand and digital teams. It has been really well received and I feel like what we’re doing with it is just the tip of the iceberg and we’re working on getting it more widely rolled out. It’s a real success – thank you!”

Lucinda Wilson, Brand Development Manager, LNER

“Having our own AI playground has been brilliant. It’s so much easier to get things done when we don’t have to worry about hiding sensitive data before asking the AI for help. It’s really sped up how we use AI in our day-to-day work.”

Juliet Dawson, Head of Brand Management, Guinness World Records

“We were all inspired by the training; you made prompting so accessible and easy to understand. The group is impatient to try it on their own! The training was well paced, full of useful information and Luke and Nick are absolute stars explaining complex things in a simple and engaging manner. Thank you.”

Natalia Khvan, VP Talent AMESA, PepsiCo

“Definition has really helped us on our AI journey, running a comprehensive deep-dive and workshop to help us assess what we need. We’ve been using Definition AI for months and it’s a game changer for the team – knowing that our information is secure is really important and the range of tools is great.”

Kay Callaghan, Head of Internal Communications, Southeastern

“As part of our AI Charity Academy, we ran a workshop where participants worked in small groups, supported by an AI expert, to develop an AI implementation plan that they could use as a starting point for embedding AI within their organisations.

“Both Luke and Nick did an excellent job facilitating their groups, guiding participants’ thinking and helping them shape practical, achievable plans. The charities left feeling energised, inspired, and ready to tackle their challenges with AI solutions.

“What impressed me most about Luke and Nick was their ability to make AI feel accessible and approachable. They avoided jargon and overly technical language, focusing instead on practical applications and real-world impact.”

Mike Reynolds, AI Programme Manager, Media Trust
