The PDF Gap
Two large listings in the Google Workspace Marketplace PDF category show the pattern we were looking for: high install counts, low satisfaction ratings.
Lumin PDF: ~22 million installs, 3.7/5.0. A generic document-to-PDF converter: ~6 million installs, 3.1/5.0.
Cross-checking against Capterra and Trustpilot added nuance. Lumin's gap is milder than the star rating suggests — it's a solid product with specific weaknesses (slow on large files, ~€20/month floor for editing access, weak team collaboration). The sharper signal came from the smaller generic converters, where the complaints repeat across multiple independent listings:
- Silent content truncation. One reviewer tested a 394-page PDF and found it capped around 80 pages and dropped embedded links and layout elements.
- Misleading free claims. "Free" in the listing, paywalled after the first use.
- Authorization errors with no in-product fix path — developer telling users to log out of extra Google accounts via review reply comments, not a UI fix.
- Manual cleanup required post-conversion. One user spent an hour fixing a 76-page document.
What we're building
A narrowly-scoped Workspace add-on: Docs, Sheets, and Slides to PDF, and PDF back to Docs. Nothing else for v1.
The core requirements come directly from the failure patterns above:
- No silent truncation. If a limit exists, fail loudly with an explanation, never quietly cap the output.
- Preserve links, formatting, and layout through conversion. Test specifically against long, complex documents.
- Minimal OAuth scope — access only the file the user explicitly opens the add-on on, not full Drive.
- Pricing stated plainly upfront. Free tier is actually free within its stated limits.
- In-product error handling for common failures, not developer replies in review threads.
The bloated all-in-one tools are where the poorly-rated products cluster. The narrow single-purpose converters cluster around 4.3+. We're staying narrow.
Next: building it.
