A first-time tour of the basics. Everything here works the same whether you're using the web app or the extension.
Drag a file straight onto the page, or click "Choose a PDF file." Nothing uploads — the file just loads into your browser's memory, the same way an image loads when you open one.
Click Add Text in the left toolrail, then click anywhere on the page to drop a text box. Type your value, drag the small handle to reposition it, drag the corner to resize. This works even on forms that were never made fillable — you're just writing directly onto the page.
Click Draw, then pick a shape from the dropdown — Freehand, Line, Arrow, Rectangle, Ellipse, Highlight, Redact, or Eraser. Click and drag over whatever you want to mark. Redact is genuinely permanent: applying it converts that page into a flat image, so the underlying text is actually gone, not just covered.
Click Form, choose a field type — text, checkbox, radio button, dropdown, date, number — and click on the page to place it. Drag the small handle to move it, the corner to resize. Decide whether to keep it as a real fillable form (for someone else to fill out later) or bake your typed values in as flat text — there's a checkbox for that right in the panel.
Click Merge, add the files you want combined, drag to reorder them, then merge. Useful for assembling a denial letter, the original claim, and supporting documents into one packet.
Click Split to break a multi-page PDF into separate files — by page range, or one file per page.
Click Download PDF (top right) any time. Every edit — text, drawings, form fields — gets baked in automatically before the file downloads. There's also a Print icon right next to it if you just need a hard copy.
Opening the extension's popup, or right-clicking a PDF link, each spawns a fully independent tab. You can have as many open at once as you want — switching between them is just normal browser tab switching. Nothing in one affects the others.
