Your Prompt Library, Always Within Reach.
At OTM, we rely heavily on AI tools every day, from refining messaging to building marketing systems for clients. But as our team and use cases grew, so did our list of prompts. They lived everywhere: docs, sheets, chat threads, and sticky notes. Finding the right one took more time than it should.
So, we built our own solution.
PromptLion is a Chrome extension that connects to a Google Sheet and gives you instant access to your entire library of optimized prompts, GPTs, and agents, all right from your browser. No hunting through files, no context switching. Just fast, focused access to the tools that move work forward.
After six months of internal use and iteration, we realized PromptLion solved a universal problem: keeping prompts organized, accessible, and consistent across a growing team. Now, we’re sharing it publicly.
What PromptLion Does
- Connects to any Google Sheet – turn it into a searchable prompt library
- Works across all major AI tools like ChatGPT, Gemini, and Claude
- Keeps prompts structured and easy to update so your team stays aligned
- Saves time by keeping your best thinking at your fingertips
Why We Built It
PromptLion started as an internal experiment to keep our AI workflows clean and consistent. As OTM scaled, it became the quiet backbone of our team’s efficiency. Every new prompt, framework, or agent got logged once and used everywhere.
Now, it’s available to anyone who wants to work smarter with AI.
