Currently, Proton Mail and Proton Drive operate as separate applications with limited integration. Users who wish to share files stored in Proton Drive via email must manually navigate to Proton Drive, create a shared link, copy it, and paste it into an email. This workflow is time-consuming and disrupts productivity.
We propose an integrated feature that allows users to:
Search and access Proton Drive documents directly within Proton Mail.
A built-in search bar or “Attach from Drive” option in the compose window.
Ability to search files by name, type, or recent uploads.
Attach or share Drive documents seamlessly.
Option to attach the file directly (respecting size limits) or insert a Proton Drive shared link automatically.
Maintain end-to-end encryption and access control (e.g., password protection, expiry date).
Unified Search Experience.
Extend Proton Mail’s search to include Proton Drive files, enabling users to locate both emails and stored documents from a single interface.
Benefits
Streamlines workflow between Proton Mail and Proton Drive.
Saves time and reduces manual steps when sharing files.
Enhances usability and encourages broader Proton ecosystem adoption.
Aligns with Proton’s privacy-focused mission while improving productivity.
Example Use Case
A user drafting an email needs to attach a previously uploaded PDF stored in Proton Drive.
Instead of opening Proton Drive separately, they can:
Click Attach → From Proton Drive.
Search for “Invoice_March2025.pdf.”
Choose to Attach as File or Insert Secure Link.
Send the email — all without leaving Proton Mail.
