AI second brain apps, thoughts?

Just curious, what are you guys using for knowledge management? (like notes, docs, newsletter ...) Been seeing these kind of AI second brain everywhere and trying out some names like notion, mem.ai, saner.ai, fabric... Haven't decided what to use yet, so would love to hear how folks are using AI for this use case

With so many options popping up left and right, choosing one seems like a bad idea. Better options are coming out every month or so.

Save your notes in a folder on your device. When you have a use case for interacting with a tool, upload the parts of your notes and references that are relevant.

This way you can have any kind of file & also use it how you want.

I tried a ton of services. Most of them are extremely immature and not ready for you to dive in and use them as a real second brain.

Obsidian for notes in markdown + Claude Code/Gemini Cli pointed to the Obsidian Vault Folder

There is probably already Obsidian Extension for this in Co-Pilot format

Still searching for something that'll take unstructured scribbles or in-the-moment notes to myself into something I can make use of long-term.

The fact that nobody has created an AI-driven product that does this confuses me.

I've just been vibe coding my own. It's the perfect use for vibe code - simple enough for a beginner to debug, easily customizable to your own workflow.

notion seems okay since you also use it for work.

Train your own brain first. Or good luck with dementia
