Four ways Buffer makes
your work better
Command-Driven Workspace
Everything at your fingertips.
Type commands to create notes, open files, launch viewers, or start drawing.
Type. Execute. Move on.
Notes + Documents, Side by Side
Think with context.
Open PDFs, slides, or websites directly next to your notes in one workspace.
Deep Linking to Real Content
Link to exact pages and sections.
Reference a specific page inside a PDF. Jump directly to a slide or heading.
Lightweight, Local-First Speed
Instant. Always.
Buffer loads in milliseconds. Notes saved locally, synced to the cloud.
Your workflow in 3 steps
From command to context to clarity — in seconds.
Create or Open
Start a note instantly with a terminal command like new or open.
Bring Context In

Think and Connect
Write. Deep-link to specific PDF pages. Reference exact sections. Save everything together.
Minimal UI. Maximum clarity.
Buffer removes visual noise so your ideas stay at the center. A terminal-first interface means every action is a keystroke away.
Just you and your work.
