OneNote alternative
OneNote is where notes live: pages, sections, notebooks, ink. Granite is where your paperwork lives (tax forms, insurance policies, IDs, statements) to be read, classified, and answered the moment it lands. If you've been jamming PDFs into a notebook and manually tagging them, you've been asking a note app to do a filing cabinet's job.
Most “best OneNote alternatives” lists are just other note apps: Evernote, Notion, Obsidian. Granite earns a spot for a different reason: if you were mainly dropping files into OneNote because it was the closest thing to organized storage, you don't want another notebook. Here's how the two compare on what document-keepers actually care about.

Why switch
Granite isn't a faster OneNote. It's a different tool for the half of your document life that a note app was never designed to handle.
Drop a PDF, a scan, or a phone photo of a form and Granite reads it immediately: identifies what it is out of 110+ document types, pulls the dates, amounts, and account numbers that matter, and files it automatically. OneNote gives you a blank page and a tag field; figuring out what you just attached is still your job, every single time. That's a fine trade for notes. It's exhausting for paperwork.
Search in Granite by asking a real question: “what's my auto insurance deductible?” or “when does my passport expire?” and it returns the answer in plain English with a link to the exact page it came from. OneNote's search finds pages that contain your words; you still have to open the attachment and hunt for the number yourself. When the document is a 40-page insurance policy, that gap matters every time you need to check something quickly.
Every file in Granite is envelope-encrypted at rest, and every sensitive extracted field is encrypted row by row. Name an emergency contact, switch on an inactivity heartbeat, and the people who'll need your documents when you can't hand them over yourself can reach the archive safely. Cancelling a plan never deletes your data. OneNote is built to hold notes; Granite is built to hold paperwork that needs to survive you.
OneNote itself is free, but room for attachments means paying Microsoft for OneDrive storage: Microsoft 365 Basic is $19.99 a year for 100 GB, and Personal is $99.99 a year for 1 TB plus Word, Excel and Teams. Granite Paid is $99 a year, and what it charges for is the work: each document read as it arrives, named and filed, with Ask to answer questions across all of them.
