I struggle with copy-pasting AI context when using different LLMs, so I am building Window to also own my context and not the AI

I usually work on multiple projects using different LLMs. I juggle between ChatGPT, Claude, Grok..., and I constantly need to re-explain my project (context) every time I switch LLMs when working on the same task. It’s annoying.

Some people suggested to keep a doc and update it with my context and progress which is not that ideal.

I am building Window to solve this problem. Window is a common context window where you save your context once and re-use it across LLMs. Here are the features:

• Add your context once to Window
• Use it across all LLMs
• Model to model context transfer
• Up-to-date context across models
• No more re-explaining your context to models

Another important problem is that these big companies will own our context and keep us locked up, forced to use them exclusively. So the vision of Window, is that the user owns the context and be free to use whatever does the job better.

Is this a valid concern? or am I wasting my time?

I can share with you the website in the DMs if you ask. Looking for your feedback. Thanks.
