A Chrome extension for AI routing that reduces friction when selecting between models like ChatGPT, Claude, and Gemini
–> Download the extension: PromptRouter Chrome Web Store
Over the past few months, I’ve found myself using more and more artificial intelligence models.
ChatGPT for some tasks, Claude for others, Gemini in specific contexts.
Over time, I realized something: there is no single “best” model.
There is only the model that is most suitable for a specific task.
The problem: choosing the model becomes a constant micro-decision
The problem is that this choice, over time, becomes a small cognitive burden.
- Need to write code? Which model should I open?
- Need to analyze a document? Maybe another one is better
- Need to reason through a complex problem? I switch again
These are decisions that take only a few seconds, but they repeat dozens of times a day.
Small frictions, but constant.
The question that led to PromptRouter
So I asked myself a very simple question:
what if the prompt itself could suggest which model to use?
From this idea, PromptRouter was born — a small Chrome extension that analyzes the prompt and automatically routes the user to the most suitable AI model for the type of request.
The idea: reduce micro-friction, not add complexity
The goal was not to build another model aggregator or add an extra layer of complexity.
I wanted to remove a micro-friction.
When working with AI, we tend to focus on model capabilities:
- benchmarks
- context length
- reasoning quality
- coding ability
But in everyday use, there is another often overlooked factor: cognitive friction.
Every extra decision, every context switch, every interruption in the workflow has a cost.
Small, but real.
How PromptRouter works
PromptRouter is built precisely on this observation.
It does not aim to replace human judgment.
It does not pretend to always know the best model.
It simply tries to make the interaction with an increasingly rich and complex ecosystem of tools more natural.
Try it
For anyone curious to try it, I’ve published PromptRouter for free on the Chrome Web Store:
It is still a young project and will likely evolve over time.
But even today, it solves a small problem I faced every day: constantly deciding which AI model to open before even starting to work.
Conclusion
In the end, an important part of innovation does not necessarily come from big revolutions.
It often comes from very simple questions:
how can we spend less time choosing tools and more time thinking about the problem we want to solve?
