Automatically resurfaces relevant previous notes based on current note

It has been built to solve the write-only problem of PKM apps.

Problem: Notes pile up, you forget them, and then you don't find them when needed, making them useless.

Solution: This app resurfaces relevant past notes automatically, based on what you’re working on now.

Jot down your thoughts, ideas, lecture notes, notes from books and internet, meeting notes, insights, or personal notes. Find them by asking questions in natural language or see automatically resurfaced relevant notes based on what you are writing now.

Why I made this app?

Obsidian is great but I found it not so useful for thinking as it doesn't show relevant previously captured notes based on what I am writing right now and hence adding notes to Obsidian became a storage where notes go and never resurfaces. This made note taking feel useless because what's the point of capturing my thoughts if I don't see them when I need it. There are few Obsidian plugins that helps with resurfacing currently relevant notes but the user experience isn't good and it also requires lots of setup.

Hence I made this app. Zero setup app which comes with a powerful model that automatically resurfaces notes that I should be looking at right now based on what I am capturing or thinking. It also allows me to search notes using natural language so I can find them by meaning instead of keywords, which helps a lot in answering my questions based on what I have previously captured.

This app can be thought of as a mix of Pinterest and search engine for your notes where you can explore your notes based on pinned notes and find answer to your questions based on your own notes.
