As answered by people managing UnionStack.ca and WorkProof.me.
UnionStack.ca's answer
UnionStack connects the people, organizations, agreements, and casework behind everyday union operations. Member records link to positions, grievances, meetings, and correspondence, helping staff understand the full context while respecting access permissions. Configurable structures and workflows let unions reflect their own organization and terminology.
WorkProof.me's answer:
here's what sets WorkProof apart from generic note-taking or documentation tools: 1. Bitcoin Blockchain Timestamping This is probably the biggest differentiator. By anchoring documents to the Bitcoin blockchain via OpenTimestamps, WorkProof creates tamper-proof, third-party verification that a document existed at a specific moment. Unlike a Word doc or Google Drive file (where metadata can be questioned), blockchain timestamps can't be altered by anyone—not you, not WorkProof, not your employer's lawyers. That's a meaningful advantage if your documentation ever faces legal scrutiny. 2. Built Specifically for Workplace Disputes Most documentation tools are general-purpose. WorkProof is designed around the specific scenarios employees face: PIPs, HR investigations, retaliation, unfair reviews. Features like conversation confirmations and review rebuttals address real pain points that someone using Evernote or Notion would have to improvise around. 3. Evidence Integrity Features The photo EXIF analysis, cryptographic hashing of emails, and late-entry flags all address credibility—the first question opposing counsel or HR would raise. These features anticipate how documentation gets challenged and build in safeguards. 4. Export-Ready Legal Packages Generating organized PDF evidence packages with verification links and blockchain proofs means documentation is ready to hand to an attorney without hours of assembly. 5. Audit Trail Transparency The distinction between when events occurred versus when they were documented shows good faith—it actually strengthens credibility by being upfront about timing rather than hiding it. The overall positioning is "documentation that can withstand scrutiny," which is different from just "a place to write things down."
UnionStack.ca's answer
UnionStack is a strong fit for unions seeking membership management, grievance tracking, communications, and member self-service in one platform. Its connected records help reduce fragmented information, while configurable workflows, reporting, and audit histories support consistent administration.
WorkProof.me's answer:
If your priority is legal defensibility: The Bitcoin blockchain timestamping is rare—most competitors rely on their own servers for timestamps, which means you're trusting the company's records. OpenTimestamps creates independent, cryptographic proof that exists outside WorkProof's control. If you're building documentation that might end up in litigation, arbitration, or an EEOC complaint, that distinction matters. If you want purpose-built features rather than DIY workarounds: General tools like Notion, Evernote, or Google Docs can technically document workplace issues, but you'd be improvising. WorkProof has specific structures for incident reports, conversation confirmations, and performance diaries—plus the AI rebuttal generator for reviews. That's less friction and less chance of missing something important. If credibility is a concern: The photo integrity analysis, late-entry flags, and full audit trails are designed to preempt challenges to your documentation's authenticity. Most note apps don't address this at all.
UnionStack.ca's answer
UnionStack serves labour unions, including locals, regional bodies, and larger union organizations. Its primary users are union administrators, membership staff, representatives, grievance officers, and finance teams. Members use the portal to access relevant information and services
WorkProof.me's answer:
The primary audience seems to be: Employees who sense they're in a vulnerable position at work More specifically: 1. People on Performance Improvement Plans (PIPs) Someone placed on a PIP often feels blindsided and wants to document their side—tracking accomplishments that contradict the narrative, preserving emails that show context, and preparing rebuttals. They know termination may be coming and want evidence ready. 2. Employees facing or anticipating HR investigations Whether they're the subject of a complaint or a witness to misconduct, these individuals need organized, timestamped records of what actually happened. 3. Workers experiencing retaliation or hostile treatment Someone who reported harassment, raised safety concerns, or filed a complaint and now notices a shift in how they're being treated. They want to document the pattern before it escalates. 4. People with difficult managers or toxic work environments Employees who've learned that verbal promises disappear, feedback shifts without warning, or their contributions get minimized. They want a private record that can't be gaslit away. 5. Anyone preparing for a potential legal claim Wrongful termination, discrimination, wage disputes—people who suspect they may eventually need an attorney and want to arrive with organized, credible evidence rather than scattered emails and foggy memories. The common thread: These are people who've realized that in workplace disputes, the employer typically holds the documentation advantage. WorkProof is for employees who want to level that playing field before it's too late.
UnionStack.ca's answer
UnionStack addresses a practical challenge: union work spans many connected records and responsibilities. A single member may hold multiple positions, participate in a grievance, attend meetings, and exchange correspondence with several representatives. UnionStack brings that context together to make everyday administration clearer and easier to coordinate.
WorkProof.me's answer:
I was harassed at work and had to leave my job. When I pursued legal action, I discovered that building my case—collecting documents, writing a timeline, connecting evidence—was traumatic all over again. I was already dealing with the aftermath of what happened, and then I had to relive it while scrambling to prove it. I built WorkProof because I didn't want others to go through that same experience. It's the tool I wish I'd had—something that lets you document in real-time, with everything organized, timestamped, and legally defensible from the start. So when you need to take action, the evidence is already there. You can focus on moving forward instead of painfully reconstructing the past. That's why features like blockchain timestamps, audit trails, and export-ready PDF packages exist. They're not abstract ideas—they're solutions to problems I actually faced. Document today, defend tomorrow. I learned the hard way that by the time you need documentation, it's often too late to create it properly. WorkProof gives people a sense of control in situations where they typically have very little.
UnionStack.ca's answer
UnionStack is built with C# and ASP.NET Core on .NET 10, using PostgreSQL and Entity Framework Core for data management. Supporting technologies include Redis, SignalR for real-time updates, OpenIddict for authentication, Azure Blob Storage for documents, and Docker for deployment.
WorkProof.me's answer:
OpenTimestamps – You mentioned this specifically for the Bitcoin blockchain timestamping Bitcoin blockchain – For the tamper-proof timestamp anchoring Some form of cryptographic hashing – For email backups and document verification EXIF metadata extraction libraries – For the photo integrity analysis AI/LLM integration – For the review rebuttal generation feature
WorkProof.me's answer:
So WorkProof.me is primarily a direct-to-consumer product serving individual employees—not companies or organizations. That fits the product's positioning well. The people who need WorkProof are typically in an adversarial (or potentially adversarial) relationship with their employer. They need a private, personal tool that's completely separate from company systems—somewhere their employer can't access, monitor, or delete their records. This audience includes:
Employees on PIPs who want to document their contributions and build a defense Workers experiencing harassment, discrimination, or retaliation People with difficult managers who want a private record of interactions Anyone who senses trouble brewing and wants to start a paper trail Employees preparing to consult with an attorney
The B2C model also means trust is critical. These users are in vulnerable situations and need to know their documentation is truly private, secure, and under their control—not accessible to employers or anyone else.
