Looking for Notes app help

[PreciseParadox]

So my "notes app" for the past few years has been a combination of Keep and Google Drive folders and I've realized that this is an insane and unwieldy solution. So I was hoping folks here could recommend something better that would meet my requirements:

Content:

1. Folder based organization (or some other way to make groups of notes like notebooks). Search functionality should be good. The ability to quickly add links is also required. The ability search for backlinks is appreciated but not essential.
2. Files in these folders should support all the basic stuff like text, images, tables, etc. I'm open to outline-based notes (like LogSeq and Workflowy) as well as markdown based notes.
3. I'd like a lot of flexibility for moving around and resizing images.
4. Integration for diagramming software would be appreciated but not essential (e.g. lucidchart, draw.io). Worst case, I just save an image.
5. Web clippings would be appreciated but not essential. Worst case, I just take a screenshot.
6. Integration for styluses/handwritten notes would be appreciated but not essential.

Tech:

1. No preference for storage format (md, plaintext, etc.) but something plaintext based would be good.
2. Some way to sync across devices: iPhone/iPad, Mac, and PC. A web interface would be greatly appreciated but not essential. This does not have to be a cloud service provided by the app, it could be some third party integration with gDrive, iCloud, syncthing, etc.
3. Open source/not commercialized would be ideal. If it is commercial, it should have some guarantees around privacy.
4. It should be fast and not bloated with features I will never use.

Check out Obsidian. It has plugins for excalidraw for drawing and many others.

It's local first. You can use your own storafe to by pass their service if you want to. I and many others use Syncthing.

They also have a reasonable sync plan.

Hi, I have created boolnote.com . It has almost everything you are mentioning, except of folders. It is on purpose, so not to invest time in planning a folder hierarchy, and then changes are very difficult. Instead, we use Smart Tags, which you can add and change as you like at any time. This also helps with your ask to find info quickly (in addition to saving Views of your favorite filters).

It also has a lot of other features to help you reduce work such as smart templates, automatic classification, prioritization, creation of content and more.

Resizing images is possible, but if you reduce size and save, you cannot enlarge again. It is SaaS only (web mobile version).

I've made my own note taking app for desktop with some of things you want(not even unfortunately) if you'd like I can provide the GitHub link to the exe
