Semptify

Every renter deserves peace at home.

An open platform protecting tenant rights through knowledge, documentation, and community — built from personal experience, offered to everyone.

The Housing Crisis
Is a Legal Crisis

Millions of American renters face housing courts, illegal evictions, and habitability violations every year — alone, uninformed, and without records. The system was never built for them.

Eviction Filings Per Year
In a typical year, U.S. landlords file about 3.6 million eviction cases — one every nine seconds. Most never go to trial. Most tenants have no idea what their rights are.

Landlords Have Legal Representation
In housing court, the power imbalance is stark. In many courts studied, 90% or more of landlords show up with an attorney — the studied average is about 84%. They know the process. They know the paperwork. They've done this a hundred times.

of Tenants Have Legal Help
In the courts studied, only about 4% of tenants facing eviction have a lawyer — in many, nearly none. The rest face legal proceedings — often with eviction or homelessness on the line — completely alone.

Housing Cost Burden

Half of U.S. renter households — a record 22.6 million — spend more than 30% of their income on housing, and 12.1 million spend more than half. For renters earning under $30,000, 83% are cost-burdened — leaving nothing for emergencies, legal help, or advocacy.

Habitability Violations

Millions of U.S. rental units have severe or moderate physical problems — mold, broken heat, pest infestations, structural hazards — and most renters don't know how to document violations, file complaints, or respond without risking eviction.

Communities Most Affected

Eviction filings fall hardest on Black renters — especially Black women — and on immigrant, elderly, and disabled renters. Eviction is not a housing event; it's a life event with cascading consequences.

We Built the Tools That
Should Have Always Existed

Semptify is non-adversarial. We don't fight landlords — we give tenants the knowledge, records, and community they need to stand with composure and clarity. Six functions. One platform. Tenants never pay.

01 — INFORMATION
Know Your Rights Before the Dispute Starts

Plain-language explanations of tenant rights — notice requirements, habitability standards, illegal fees, retaliation protections, and more — covering 35 states today and expanding. Accessible to everyone, not just lawyers.

Open the Law Library
02 — RESEARCH
Go Deeper on Your Specific Situation

Not every situation is the same. Semptify's research layer helps tenants explore the statutes, precedents, and agency rules relevant to their exact case — without needing to know where to look.

See legal research tools
03 — DOCUMENTATION
A Paper Trail You Can Trust

Every communication, payment, repair request, and notice — documented, timestamped, and organized. A complete paper trail stored in your own cloud, ready if you ever need it in court or with a mediator.

Start documenting
04 — ORGANIZE
Scattered Texts, Photos, Receipts → Coherent Record

Most tenants have the makings of a record — it's just scattered across phone photos, email threads, text messages, and handwritten notes. Semptify organizes everything into a coherent, chronological record that tells your story clearly.

Organize your records
05 — COLLABORATE
Find Your Tenants Union. Build One If It Doesn't Exist.

Tenants are stronger together. Semptify connects renters with their local tenants unions, tenant advocacy organizations, and community support networks — and provides tools for organizing where nothing yet exists.

Advocacy & organizing
06 — BE HEARD
File Complaints. Reach Legislators. Tell Your Story.

Semptify's Public Exposure Suite connects tenants to journalists, housing advocates, and elected officials. The Complaint Wizard guides users through HUD, state AG, and code enforcement filings — step by step, plain language, no lawyer required.

20+ Tenant Tools,
Built to Matter

Every feature in Semptify answers a specific, real gap in the tenant experience. From the first lease signature to the last day in court.

Group A — Core Tenant Tools
Know Your Rights Law Library

Housing law in plain English for 35 states and growing. Covers notice requirements, security deposit rules, habitability standards, retaliation protections, and right-to-cure timelines. No law degree required.

Open the library
Document Vault

Your tenant document vault lives in your own Google Drive, Dropbox, or OneDrive account — not on Semptify's servers. Lease agreements, repair photos, payment receipts, notices: all organized and owned by you.

Set up your vault
Unified Timeline

Every event in your tenancy — payments, notices, calls, repairs, inspections, disputes — presented as a single chronological timeline. The clearest possible picture of what happened, and when.

Build your timeline
Case Builder

Automated documentation from your records. Case Builder takes your vault contents and timeline, identifies the strongest documentation, and assembles it into a clear, coherent case narrative ready for legal or advocacy use.

See services
Complaint Wizard

Guided, step-by-step filing with HUD, state attorneys general, local housing authorities, and code enforcement agencies. The Wizard pre-fills forms from your vault data and walks you through every field in plain language.

File a complaint
Group B — Advanced & Legal Tools
Eviction Defense Module

Step-by-step guidance through the eviction process — from notice receipt to court date. Includes state-specific court procedure guides, timeline calculators, deadline tracking, and response templates drafted in plain language.

Open eviction defense
Court Forms System

Pre-filled legal documents drawn from your vault and timeline. Generates answers to eviction summons, motions for continuance, habitability defenses, and more — with state-specific formatting and instructions for filing pro se.

See tools
Litigation Intelligence

Pattern detection across public housing court records. Identifies serial evictors, landlords with histories of retaliation or code violations, and systemic practices — giving tenants and advocates actionable intelligence to level the playing field.

Legal research tools
Fraud Exposure

Document and surface predatory landlord patterns: illegal fees, false security deposit claims, retaliatory lease terminations, habitability cover-ups, and discriminatory practices. Creates a documented record for regulatory and legal action.

Legal research tools
Public Exposure Suite

Bridges the gap between individual tenants and systemic change. Connects tenants with housing journalists, policy advocates, and legislators. Makes individual stories part of a larger record — with privacy controls tenants control.

Advocacy & outreach
Forensic Evidence System — FEMS

Advanced document processing: OCR of scanned documents and photos, automatic deduplication, SMS and chat import, metadata preservation, and chain-of-custody logging. Turns a phone's camera roll into a clear, credible record.

Semptify Go — Mobile PWA In Development

Full Semptify functionality in a Progressive Web App — now in active development. Document in the moment — photograph a notice, import texts, check your rights, or access your vault — anywhere, on any device. Offline-capable, installable, fast.

Your Data Never
Touches Our Servers

Semptify's storage-based authentication model is a genuine innovation in tenant-facing technology. Your cloud storage account is your identity. Your documents never leave your control — and our standing promise: nothing on our servers beyond what is absolutely necessary and non-identifiable. If that ever fails in production, the project doesn't deserve to run.

Zero Passwords

You connect Google Drive, Dropbox, or OneDrive. There is no Semptify password to create, store, remember, or lose. Your own cloud storage confirms it's you.

📁

You Own Your Data

Every document, timeline entry, and case record is written back to your own cloud account — timeline data included, held in your own storage. Semptify holds zero personal files. If Semptify disappeared tomorrow, your records would still be exactly where you left them.

🌐

Portability

Your identity and your records travel with your cloud account. Switch devices, reinstall the app, or share access with a lawyer — your entire tenancy record comes with you, without re-registration.

Founded from Personal Experience

Semptify was created by Bradley Crowe following a personal navigation of a housing dispute. The experience made clear that the gap between tenants and their rights was not a knowledge problem — it was an access and systems problem. Semptify exists to close that gap, for everyone who faces it after him.
