AI for your business

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

We decided it would be safe, perfect for a range of different brand, marketing and comms tasks, and wouldn’t blow your budget.

Soon we began to imagine an AI suite that let you move from model to model to get the results you wanted, keeping your data locked away from AI model training.

That sounded great, but there was nothing around like it – so we built it. And now we’re building it for our clients too.

Definition AI is your AI. It’s a fully encrypted AI suite, giving you access to all the best models in the world in one place. And you can customise it and brand it.

That means support for every function of every department in your business. And you pay for usage not users, which can save you a ton of money.

Training

We know that businesses are at different stages of adoption and integration with AI, so we’ve designed our training services to match.

That starts with the basics for new users (covering AI literacy for workers in line with the EU AI Act).

At the other end of the scale, we offer in-depth, tailored prompt and context engineering workshops focusing on everything from language and reasoning to image and video creation.

And like all our training, we’ve worked with companies all over the world, face to face and virtually, designing sessions that are interactive and fun as well as super practical.

Specialist consultancy

We’ll analyse the problems you’d like to solve with AI, and suggest solutions.

That might mean picking the right model, because different AI models are good at different things. Some are more expensive to use than others. And they work at different speeds.

And it might mean creating bespoke prompts, agents and assistants.

Bespoke prompts

Anyone can get content or insights out of an AI tool. But it takes a specialist to get the very best.

Take writing, for instance. It takes a writer to specify Latinate or Anglo-Saxon vocabulary, or the intricacies of active and passive voice, or the difference between abstract and concrete nouns.

Or video. It takes an experienced producer to develop a shot list, make a video sequence flow, or direct a voiceover to enhance the images on-screen.

Combine that with AI experts who know about things like few-shot and chain-of-thought prompts, as well as really technical bits like temperature testing (a way to regulate how creative the output is), and you’ve got all the knowledge you need to refine a prompt to perfection.

Let’s create your prompts

Agents and assistants

Our AI assistants use the latest models and tools from OpenAI and Anthropic. We also build custom tools for assistants to tackle particular challenges.

We work out the ideal combination of instructions, data, models and tools, rigorously test the assistant and then deploy it to your private AI suite, ready for you to use.

Fine-tuning

There are lots of reasons we’d fine-tune an AI model for you:

to make sure all the images it creates are on brand
to turn your AI into a brand ambassador by mastering your tone of voice.
to answer questions specific to your company’s products or services

…and many more.

We’ll fine-tune your model with hundreds (sometimes thousands) of original before-and-after examples. It does the same job as a prompt, but more so, making sure everything your team generates is bang-on brand.

And much more

We’re also helping our clients with all sorts of other AI projects including…

Video generation and production
Stock image generation
Translation
Chatbot development

“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

“Manda gives parents a better option for high-quality AI tutoring. With so many generic tools flooding the market, we saw an opportunity to deliver something truly aligned to the UK national curriculum, yet still affordable.

“Definition realised we were sitting on a wealth of high-quality training data and worked out how we could use it to increase access to our industry leading tuition services – they explained how the process would work and helped deliver an amazing AI tutor on time and on budget.

“Manda channels the expertise of our human teachers into accessible, consistent, and effective tutoring for everyone.”

Josh Blackburn, CEO, TLC LIVE

“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.”
