Toolbox

by Kepler

The web is for exploration, productivity and creativity. In this toolbox you’ll find the free tools we wanted to make for everyone.

Prompt library

Each prompt sets up an assistant for one job. Save it as an agent in Microsoft 365 Copilot, a custom GPT in ChatGPT or a Project in Claude, and it’s there whenever the job comes round.

Questions

What’s in the Toolbox?
Design tools, starting with a shader background generator for designers and developers, and a prompt library of 3 prompts: status update agent, meeting notes agent and project onboarding agent.
Can I use them at work?
Yes. Copy the prompts, change them and share the agents you build, at work or for clients. The shader generator’s code is under the MIT licence.
Which AI tools do the prompts work with?
Microsoft 365 Copilot, ChatGPT and Claude. Save a prompt as a Copilot agent, a custom GPT or a Claude Project, and each prompt’s page shows the steps for all three.
Who makes the Toolbox?
Kepler, which saves what you find on the web for you, your team and your AI. These are what we build along the way.
