Show HN: I Got Sick of Juggling Apps, So I Merged Them

Hi HN community,

I built this because I was tired of juggling 3–4 different tools just to work on a single project. When I’m doing research, analysis, plain old reading or knowledge work I usually have:

A note-taking app open

A PDF viewer in another window

ChatGPT in a separate tab

Switching between them constantly killed my focus and made it harder to connect information.

So I decided to merge everything into one workspace:

Rich text editor for notes

PDF viewer for reading & annotating documents

AI chat assistant for instant summaries, Q&A, and analysis

You can open multiple files at once and resize panels however you want. It’s already been helpful for students, lawyers, consultants and pretty much anyone with multiple sources of information at once or just likes to have everything in one window.

I’d love for you to try it and tell me what you think, what works, what doesn’t, and what’s missing.
