To Get Started
The Problem

Owning rental properties shouldn't
feel like a second job.

Hours lost to PM statements

Manually reading email attachments, entering transactions, and reconciling numbers across properties every single month.

Tax season nightmares

Schedule E requires splitting mortgage payments into principal, interest, insurance, and taxes. Spreadsheets can't keep up.

Documents scattered everywhere

Leases in email, insurance in a folder, PM contracts in another. Nothing is connected to the right property.

No real-time portfolio view

What's my NOI this quarter? Which property is underperforming? Is my cash-on-cash return improving? You should know instantly.

Meet Knox

Meet Knox. Your AI does everything.

Knox reads 72+ real estate document types, processes PM statements, tracks taxes, monitors your portfolio 24/7, and talks to you wherever you are. Five ways in. Zero busywork out.

Hey Knox, I just closed on a duplex at 422 Maple Dr. Can you set it up?
Done! I created 422 Maple Dr and set it as a duplex. Send me the closing docs and I'll fill in purchase price, loan terms, and insurance automatically.
closing_package.pdf
Got it. Here's what I extracted:
✓ Purchase: $245,000
✓ Loan: $196K @ 7.25% / 30yr
✓ Insurance: State Farm, $1,840/yr
✓ Entity: Maple Holdings LLC
✓ Health score: 62% — send me the lease to hit 80%+
What's my total cash flow this month?
Across all 8 properties: $6,842/mo net cash flow. Your best performer is 815 Oak Ave at $1,240/mo. 422 Maple Dr isn't generating income yet — want me to flag it when the first rent payment comes in?
