Product summary

Review the store description, core capabilities, and common use cases.

Sign, edit, and share PDFs right from your Chrome™ browser or Gmail™ inbox.

Sign email attachments and draft replies with signed documents attached without leaving your Gmail™ inbox. Use the DocHub extension for Chrome™ to open PDFs from a web URL in DocHub and then edit, sign, or share them with others.

With DocHub's powerful editor, you can add text, images, comments, and highlights. You can also white out information, and underline or strike out text anywhere on a document without losing the document's original quality.

Sign PDFs sent as email attachments using DocHub. Add your signature by drawing, typing, or uploading its picture. Once signed, you can reply to an email with the signed document attached — all without leaving your Gmail™ inbox.

Manage your PDFs online. With DocHub, you can rearrange, add, and delete pages, or merge entire PDFs to create a new file with just a few clicks.

Frank's Tax Service (FTS2)2018年10月15日

So far this program has been worth the cost of Premium.

Shakthivel Chinnathambi2018年10月14日

Unable to add more signatures. It un-necessarily blocks us and compels us to buy a premium version, which is a headache

Beverly McGaw2018年10月13日

So far, so good

AI product read

Chrome extension that acts as a launcher/bridge to open PDFs from Gmail attachments or Chrome's built-in PDF viewer into the DocHub web app for editing, signing, and sharing

Enables users to sign and edit PDF email attachments without downloading them separately, streamlining the PDF signing workflow directly from Gmail and Chrome's PDF viewer

1) User views a PDF attachment in Gmail → DocHub button appears. 2) User clicks DocHub button → extension opens an iframe modal (blank.html → dh-launcher.js) loading dochub.com/import-gmail-attachment with email, message ID, and attachment metadata. 3) For PDFs in Chrome's PDF viewer, 'Open in DocHub' button fetches the PDF, caches it, and redirects to dochub.com/import-file. 4) DocHub web app handles actual editing/signing. 5) Extension receives messages from DocHub to close iframe and navigate Gmail to drafts with signed document attached.

Target users: Gmail users who need to sign PDF documents / Business professionals handling PDF contracts and agreements / Users who want to streamline PDF signing without leaving Gmail

Extension source is minified/webpack-bundled, making deep code analysis harder
Cannot inspect the dochub.com web app's login/payment UI from extension source alone
The cs-dochub-website.js content script only injects a meta tag with the extension UUID—no login or payment logic visible

Monetization

No paid features detected

The extension source contains no billing, subscription, upgrade, Stripe, or payment-gating code. The keyword 'upgrade' appeared only in the heuristic but grep found zero matches in actual source files. The 'pro' keyword hits were all false positives from file paths containing 'production', CSS class names like 'projector', or license text. DocHub.com as a destination service does have paid Pro plans, but the extension itself does not gate features or reference pricing/billing.

Confidence: 75
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension is a thin launcher that redirects all PDF editing/signing workflows to dochub.com (Config.HOST='https://dochub.com'). The Gmail content script opens an iframe to '/import-gmail-attachment' and the PDF viewer script redirects to '/import-file' on dochub.com. DocHub.com requires a user account to save, sign, and manage documents. The extension itself has no login UI—it delegates all authentication to the destination web service.
