Note Bridge is data migration software for knowledge workers who need to move their entire OneNote and Obsidian library into Notion without losing content. It is a web app, not a desktop tool or a browser extension. You sign in with Microsoft and Notion, scan your notebooks, see exactly what will move and how much it costs, and run the migration in the background. You get an email when it is done. The product exists because the existing free routes work fine for small notebooks but break down at scale. Notion's zip import is capped at 5MB on the free plan. The Obsidian Importer hits Microsoft Graph API rate limits, has no progress bar, and can take hours on a 1500-page notebook. Audio attachments and ink strokes do not survive a Notion zip import. Tables nested inside bullet lists, code blocks, or blockquotes break during conversion. Note Bridge was built to handle the cases the free tools drop. What it preserves: notebook โ†’ section โ†’ page hierarchy, images, PDFs, tables, audio attachments, ink drawings rendered to SVG, LaTeX equations, and arbitrary file attachments. It uses the Microsoft Graph API to read OneNote and the official Notion API to write. Pricing is tiered by total page count of a single migration: Free up to 20 pages, Personal $9 up to 200 pages, Pro $29 up to 1,500 pages, Power User $79 up to 5,000 pages, Business custom for 5,000+. Price scales smoothly between tiers, so you only pay for what you need. An empty-delivery auto-compensation system refunds credits for any page that arrives empty in Notion. Note Bridge is listed on the official Notion Integration Gallery and available in eight languages. Best fit: heavy OneNote or Obsidian users with 200+ pages who cannot afford to lose content.

Questions & Answers

As answered by people managing Slingcode and Note Bridge.

What makes your product unique?

Note Bridge's answer:

Built specifically for OneNote-to-Notion migration at scale. Handles cases the free routes drop: ink drawings (rendered to SVG), audio attachments, LaTeX equations, tables nested in lists or code blocks, and notebooks larger than Notion's 5MB zip import limit. Runs server-side with retry and resume logic, so Microsoft Graph API rate limits do not kill the job. Includes an empty-delivery auto-compensation system that refunds credits for any page that arrives empty in Notion.

How would you describe the primary audience of your product?

Note Bridge's answer:

Heavy OneNote users with several hundred to several thousand pages who are migrating to Notion and cannot afford to lose content. Researchers, students, writers, and knowledge workers with multi-year notebooks. Light users with small notebooks should use the free Obsidian Importer route instead.

What's the story behind your product?

Note Bridge's answer:

I tried to migrate my own OneNote notebooks to Notion using the existing free tools and watched content disappear: ink strokes gone, audio attachments missing, tables broken, hours-long jobs failing silently with no progress bar. The free routes work fine for small notebooks but break down at scale. Note Bridge is the tool I wished existed when I started, so I built it.

Why should a person choose your product over its competitors?

Note Bridge's answer:

Free routes like the Obsidian Importer work for small notebooks. Note Bridge is the right choice when losing content is not an option: 200+ page libraries, years of PDFs and audio attachments, or research archives you cannot manually verify page by page. You scan first, see exactly what will move and what it costs, then pay. Pricing is tiered by page count (Free / Personal / Pro / Power User), and scales smoothly between tiers so you only pay for what you move.
