We check your files first. Checkout appears only when Opren can generate a substantive report.
You will not be asked to pay unless we can read enough from your proposal to generate a useful report.
Your files are used to generate your report and may be processed by our extraction providers. We do not retain them for product improvement unless you separately opt in.
How we handle your files
We may briefly hold a temporary file hash and extracted draft so a re-upload does not have to be processed again. The optional product-improvement choice appears later, beside the Analyze button, and is unchecked by default. Read our Privacy Policy.

Why Opren is different
Opren does not sell installer leads and does not accept payment from installers to influence results. Vendor savings and payback figures are treated as claims to verify — not as guaranteed outcomes.
Frequently asked questions
Standard installer proposal PDFs from solar and battery companies serving California PG&E or SCE territory — the kind you would receive by email after a sales call. Scans work, but clear text-based proposals extract more reliably.
