Enterprise DRM Meets Document Sharing with Invoicing
Digify and PaperLink both let you share documents with page-level analytics and access controls. Both track who viewed your file, which pages they read, and how long they spent on each. Both support password protection, email verification, and expiration dates.
The difference is in positioning. Digify is a document security platform with patented DRM technology - it protects files even after download and targets enterprise teams running M&A deals, due diligence, and board reporting. PaperLink combines document sharing with invoicing and estimates - share a proposal, track who read it, send the invoice, all from one account.
This comparison covers real differences across eight categories. Where Digify is stronger, we say so. Where PaperLink offers more, we show it.
Security and Access Controls
Security is where Digify invests most of its engineering. The platform is ISO 27001 certified and HIPAA compliant, with features specifically designed to prevent unauthorized document distribution.
| Control | Digify | PaperLink |
|---|---|---|
| Password protection | All plans | All plans |
| Email verification | All plans | All plans |
| Expiration dates | All plans | All plans |
| Download control | All plans | All plans |
| NDA / agreement gate | All plans | All plans |
| Dynamic watermarking | Team plan+ (~$480/mo) | Coming soon |
| Screenshot protection (Screen Shield) | Team plan+ (~$480/mo) | Coming soon |
| Post-download access revocation (PPAD) | All plans | Not available |
| Custom URL slugs | Not available | Paid plans |
| SSO (Okta, Azure AD, OneLogin) | Team plan+ | Not available |
Digify's standout feature is PPAD (Persistent Protection After Download) - a patented technology that encrypts files so access controls remain active even after the recipient downloads them. You can revoke access, change permissions, or set expiry dates on files that already live on someone else's device. The downloaded files open in the browser without plugins. No other platform in this comparison offers anything similar.
Digify's dynamic watermarking and Screen Shield (screenshot protection) are genuine enterprise features, but they require the Team plan at approximately $480 per month. PaperLink does not yet offer watermarking or screenshot protection. If preventing unauthorized screenshots and enforcing visible recipient identification on every page are requirements, Digify is the stronger choice.
PaperLink supports full custom domains for shared links on Business plans and above - your documents appear at docs.yourdomain.com. Digify does not offer custom URL slugs for individual document links.
Analytics
Both platforms track document engagement at the page level. The core metrics overlap.
| Metric | Digify | PaperLink |
|---|---|---|
| Page-by-page time tracking | Yes | Yes |
| Viewer email (with gate) | Yes | Yes |
| Country/location detection | Yes | Yes |
| Device and browser | Yes | Yes |
| Download tracking | Yes | Yes |
| Real-time view notifications | Not available | Yes (Slack, Telegram coming soon) |
| Print tracking | Yes | Coming soon |
| Permission change history | Yes | Not available |
| Folder-level analytics | Yes (data rooms) | Yes (all plans) |
Digify records a full audit trail including permission changes, which matters for compliance-heavy workflows where you need to demonstrate who had access to what and when. This is particularly relevant for M&A transactions and regulated industries.
PaperLink provides AI-powered document analytics with credit-based billing - owners can ask questions about document content and get instant answers based on the actual pages.
Pricing
This is where the platforms differ most dramatically.
| Plan | Digify | PaperLink |
|---|---|---|
| Free tier | 7-day trial only (3 users, 5 guests) | Free plan (permanent) |
| Entry paid | Pro: ~$130-180/mo (1 user, 3 data rooms) | Pro plan |
| Mid-tier | Team: ~$480/mo (3 users, 10 data rooms) | Business plan |
| Enterprise | Custom pricing | Enterprise plan |
| Billing model | Per plan tier (users capped per tier) | Per team |
| Storage | 100 GB all plans | Scales with plan |
| File size limit | 5 GB per file | Scales with plan |
Digify does not have a permanent free plan. After the 7-day trial ends, shared files become inaccessible to recipients until you subscribe. The entry-level Pro plan starts at approximately $130 per month (annual billing), which is a significant commitment for freelancers and small teams.
PaperLink offers a permanent free plan with core sharing controls, analytics, and invoicing. The pricing gap is substantial - a solo user pays nothing with PaperLink versus $130+ per month with Digify.
Digify's pricing reflects its enterprise positioning. The security features (PPAD, Screen Shield, dynamic watermarking) justify the cost for teams handling sensitive M&A documents or intellectual property. For teams sharing proposals, pitch decks, or client deliverables, the security premium may not match the use case.
If your documents contain trade secrets, pre-release IP, or legally sensitive M&A materials that require post-download protection, Digify's security features justify the price difference. For standard document sharing with analytics, the cost gap is harder to justify.
Invoicing and Estimates
Digify does not have invoicing features. It is a document security and analytics platform.
PaperLink includes a full invoicing and estimates system: create invoices, send them to clients, track payment status, convert estimates to invoices, manage financial accounts, and handle multi-currency billing. No other document sharing platform in this comparison offers this.
The practical impact: if your workflow is "share a proposal, track engagement, send an invoice" - PaperLink handles all three steps from one account. With Digify, you need a separate invoicing tool and manage client data across two platforms.
Data Rooms
Both platforms support virtual data rooms, but Digify's VDR is a significantly more developed product.
| Feature | Digify | PaperLink |
|---|---|---|
| Data rooms | Yes (dedicated VDR product) | Yes (folder-based) |
| Multi-document sharing | Yes | Yes |
| NDA before access | Yes | All plans |
| Q&A sections | Yes (structured due diligence Q&A) | Yes (AI credits) |
| In-app document editing | Yes (Word, Excel, PowerPoint) | Not available |
| Excel What-If modeling | Yes (protected environment) | Not available |
| Drag-and-drop folder structure | Yes | Yes |
| Full-text search within data room | Yes | Coming soon |
| Custom branding (logo, colors, URL) | Yes | Custom domain |
| Per-folder permissions | Yes | Yes (role-based) |
| Index numbering | Yes | Not available |
| Post-download protection in data room | Yes (PPAD) | Not available |
Digify's data rooms are built for formal M&A and due diligence processes. The in-app document editing is notable - recipients can edit Word, Excel, and PowerPoint files directly inside the data room without downloading them, with version history tracked. The Excel What-If modeling feature lets recipients test financial assumptions within the protected environment. These are features that matter to investment banks, law firms, and advisors running complex transactions.
PaperLink handles data rooms through its folder system with role-based permissions, AI-powered Q&A, document request uploads, and welcome messages. It covers the standard data room use case - controlled multi-document sharing with analytics and access controls. For enterprise-grade due diligence requiring in-app document editing, Excel modeling, and post-download PPAD protection, Digify is the stronger tool.
File Format Support
| Format | Digify | PaperLink |
|---|---|---|
| Yes | Yes | |
| Office documents (Word, Excel, PowerPoint) | Yes (in-viewer + in-app editing) | Yes (converted) |
| Images | Yes | Yes |
| Video | Yes (view-only, no print) | Coming soon |
| Audio | Yes | Not available |
| Markdown import | Not available | Yes |
| Claude artifact import | Not available | Yes |
Digify supports a wider range of file formats, including video and audio playback within the secure viewer. The Office document support goes beyond viewing - recipients can edit files in the browser without downloading them.
PaperLink differentiates with Markdown import and Claude artifact import - paste AI-generated content or a Claude artifact URL and convert it directly to a trackable shareable document. This is a workflow specific to teams that generate content with AI tools.
Integrations
| Integration | Digify | PaperLink |
|---|---|---|
| Salesforce | Yes | Coming soon |
| HubSpot | Yes | Coming soon |
| Slack | Yes | Yes (real-time view notifications) |
| Outlook extension | Yes | Coming soon |
| Gmail extension | Yes | Coming soon |
| Google Drive / OneDrive / Dropbox | Yes (import/sync) | Coming soon |
| Zapier | Yes (9,000+ apps) | Coming soon |
| SSO (Okta, Azure AD, OneLogin) | Yes | Coming soon |
| Google / LinkedIn auth | Not available | Yes |
| Custom domain | Custom branding | Yes |
Digify has a substantially deeper integration ecosystem. The CRM integrations (Salesforce, HubSpot), email extensions (Outlook, Gmail), cloud storage sync, and SSO support reflect its enterprise positioning. If your team runs on Salesforce or needs SSO for compliance, Digify covers these requirements.
PaperLink's integration ecosystem is smaller at this stage. It supports Google and LinkedIn authentication, Slack for real-time view notifications, a Chrome extension for quick document sharing from the browser, and custom domain configuration.
Who Should Choose Which
Choose Digify if:
- You handle M&A, due diligence, or board-level documents
- You need post-download access control (PPAD technology)
- Your organization requires ISO 27001 and HIPAA compliance
- You need in-app document editing within data rooms
- Your team relies on Salesforce, HubSpot, or SSO
- Dynamic watermarking and screenshot protection are requirements
Choose PaperLink if:
- You need document sharing and invoicing in one platform
- You want a permanent free plan, not a 7-day trial
- Budget matters - PaperLink costs a fraction of Digify's entry price
- You share AI-generated content (Markdown, Claude artifacts)
- You operate in multiple languages (eight locales supported)
- Your workflow is proposal - share - invoice and you want one account for all three steps
- You want custom URL slugs on paid plans and custom domains on business plans
The Positioning Difference
Digify is a document security company first. Its engineering investment goes into DRM, encryption, and persistent file protection. The PPAD technology is a genuine moat - no competitor in this space offers post-download access revocation at the same level. The price reflects enterprise value: $130-480+ per month buys security features that matter when a leaked document could derail a billion-dollar transaction.
PaperLink combines document sharing with invoicing and financial management. The pitch is concrete: share a proposal, track who read it, send the invoice - all from one account. Both platforms offer data rooms, analytics, and access controls, but PaperLink adds a financial layer that Digify does not have, while Digify adds post-download security that PaperLink does not.
The right choice depends on what you protect and why. If you run M&A deals and need to prevent document leaks with post-download controls, Digify's security depth is real. If you run client work that spans proposals, shared documents, and invoices, and you want a product that connects those steps without an enterprise price tag, try PaperLink.
