Making my personal notes the center of my AI chats

As the battle for AI rages on, all of the major players (such as ChatGPT, Claude, and Gemini) are fighting to be the one you use most often. Because the memory of these tools is continuing to improve, the more you use one of them the more helpful it becomes. The downside is that the more a particular AI tool knows you, the more difficult it is to leave.

I suspect that the next few years will see a lot of shifts when it comes to ads and pricing, so keeping your options open will be increasingly valuable. While it’s not a simple solution, I’ve created something that you might be able to do yourself if you’re so inclined.

Over the last six months, I’ve moved my main notetaking system in a custom app that I built for myself in Lovable. It’s not available for others to use, but like most AI-built apps, that’s ok. This notes app fits me perfectly, and you can create your own that fits you.

I’ve set my notes app so that it syncs to an OpenAI “vector store”, which means I can have super fast AI chat about everything in my notes. It also means that if I decide that I want to use someone other than OpenAI I can just point my notes over there and use it instead. The main source of data for my AI chats is in my notes, that I control.

Here’s a quick video on how it works:

As I mention in the video, I don’t really understand how vector stores work, nor do I need to. I simply told Lovable to set it up and it walked me through the steps. If the time ever comes where it makes sense to move to a different provider, I can simply move.

The coming years will be super interesting when it comes to AI, but I figure it’s not a bad thing to have control over your notes and chat and this has turned into a pretty great way to to do it.
