For real estate agents, their clients and homeowners

Film the house. Know what you’re looking at.

Grainwork turns a short phone video into something you can use: a briefing after a showing, a price range for a repair, or a new look for a room. It also tells you what the camera couldn’t see.

Buyer briefings come through your agent. Repair estimates, Bid Check and Renovations Lite are in the app.

The demo takes a few minutes. No sign-in.

The top of a Grainwork buyer briefing on an iPhone. It reads: Before you buy. Buyer briefing. Your second read. This video visibly covered 5 of 9 house systems. Treat every unseen or partly shown area as an inspection question.

5 of 9 home systems showed up in the video. The other 4 didn’t show up, so the briefing tells you to ask the inspector.

A few seconds from a real walkthrough filmed in June 2026. The briefing is from the full walkthrough of the same house, run through the app in September 2026.

A real example

A real estimate, start to finish

Our founder filmed 16 seconds of chewed door trim on a phone. This is the estimate the app saved.

A frame from the repair video: white door casing at the foot of a staircase, scratched and chewed along its lower edge.

Film a Repair · saved estimate

Replace the damaged door trim.

Scratched and chewed casing at the foot of the stairs.

$510 to $655 including one service visit

  • About 3 hours of labor
  • About 8 feet of trim
  • $50 of materials: casing, wood filler, caulk, primer and paint

Hours and trim length were estimated from the video, not measured. Labor and the one service visit make up the rest of the range. The labor rate the app used wasn’t saved with this example.

Before a contractor quotesConfirm how much trim is damaged, the shape of the trim and how much painting is needed.

A real estimate from the app, April 2026. The app has changed since then.

What we won’t pretend

If the camera didn’t see it, we say so.

It’s not a home inspection. Every briefing lists what the video didn’t show and turns it into a question for the inspector.

Estimates list what they assume.

Each estimate lists the hours and materials it assumed, and says when a service visit is included. A contractor still confirms the price.

Where labor rates come from.

Labor is priced with a rate for the area, based on U.S. Labor Department wage data for construction workers.

Your information isn’t for sale.

We never sell your name or pass you to contractors.

The starting photo: a galley kitchen with pale gray cabinets, white counters and a subway tile backsplash. Starting photo
The Renovations Lite concept for the same kitchen: sage green cabinets with brass pulls, stone-look counters and a tall stone tile backsplash. Renovations Lite
The starting photo (with some clutter removed) and the Renovations Lite result from the app. The result also removed most of the counter items and changed the wall art. A design idea, not construction drawings.

What we’re building toward

A record that stays with the house.

Every walkthrough, repair and estimate should be kept, so the next owner, agent or contractor starts with what’s already known. We’re also teaching Grainwork to build a 3D model of a room from ordinary iPhone video. That part is research.
