Grainwork turns a short video or photo of home damage into a contractor-grade repair estimate — and can compare a contractor's quote with that estimate to show where the scope or numbers differ. Here's how to get the most out of it, and how to reach a real person if something's off.
Open the app, film about 60 seconds of the damage (or take a photo), and narrate what you see as you go — your voice makes the estimate noticeably better. In about a minute you'll get a repair estimate, priced line by line and calibrated to contractor rates in your ZIP code. Estimates are free.
No. You can use Grainwork without signing in. Signing in with Apple or Google saves your estimates across devices and keeps your home's history together.
If a contractor has given you a written quote, Grainwork can compare it with the estimate from your walkthrough, show where the numbers or scope differ, and give you focused questions to ask. It is an independent comparison, not a local-market verdict. We don't sell leads and we don't refer you to contractors.
The quote-to-estimate comparison is free. The full line-by-line breakdown, conversation guide, and report use consumable Bid Check credits bought through the Apple App Store on Apple devices or Google Play on Android. Payment is handled by the store you use; your card details are never shared with us.
Bid Check credits are consumable in-app purchases, not permanent store entitlements with a generic Restore Purchases action. If you reinstall Grainwork or switch devices, sign in to the same Grainwork account you used when you bought the credits. Your unused credit balance is kept with that Grainwork account and should appear after it syncs.
Using the same Apple or Google store account by itself does not move credits between different Grainwork accounts. If a completed purchase is missing, do not buy it again just to recover it. Email [email protected] with the Grainwork sign-in email, whether you used the Apple App Store or Google Play, the approximate purchase date and time, and the store transaction or order ID if available.
They're used to generate your estimate and may help Grainwork calibrate its pricing over time. If you delete your account, your uploaded media, extracted frames, saved results, and account-linked analysis and review material are permanently removed. Full details are in our Privacy Policy.
You can delete your account directly in the app, under Settings → Delete account. Anonymous users will see Delete my data. That removes your account or anonymous session data, saved estimates and Bid Checks, profile details, saved documents, unused Grainwork credits, uploaded media, and account-linked analysis and review material.
