See what works todayWhy AppraisalOS
One connected system for the whole appraisal workflow.
The order comes in, the borrower books the inspection on your calendar, the field work lands in the supported UAD 3.6 report, internal readiness checks run, and you build a candidate package — in one system, with Aria's optional guidance and the supervisor + trainee workflow on the same spine. Internal readiness checks can surface supported issues before delivery.

Schedule · borrower self-service
Offer the times. Let the borrower choose.
Send a secure link built from the appraiser's working hours, days off, personal blocks, and booked inspections. The borrower books an open window or says none work; the order updates and the appraiser is notified.

Carry the order into the field.
Open assigned orders, update status, capture report fields, required photos and GPS, scan supported rooms with LiDAR, sketch to ANSI, and record voice notes. Offline work queues safely and syncs back to the desktop workspace.

Fill the field. See the rule. Keep moving.
The workspace follows the report while Aria keeps the active field, its source, and its delivery impact in view. Nothing is applied without the appraiser.

Auden is a private-beta internal review assistant for the latest generated PDF, XML, and ZIP. Auden is designed to attach artifact context to eligible findings, but it may miss issues or produce an incorrect finding. It cannot approve, alter, sign, or submit a report.

Guidance that shows its work.
Ask what belongs in a field, draft commentary, or review a blocker. Aria cites the source and leaves the decision with the appraiser.

Supervisor + trainee · Rhode Island private beta
Supervision belongs inside the work.
A supervisor and a trainee share the same file, and every hour the trainee logs waits in the supervisor's queue to be approved or rejected with a reason. AppraisalOS keeps the record; it does not provide a supervisor or award a credential.

FAQ
The questions every appraiser asks.
The URAR is built around UAD 3.6 sub-block authoring. Supported fields can show definitions, allowed values, and source context, and supported local H-1 checks run before package download. Coverage is still being expanded. Official portal and GSE acceptance remain external.
Auden is a private-beta internal review assistant for the latest generated artifacts. It is designed to attach artifact context to eligible findings, but it may miss issues or produce an incorrect finding. It cannot approve, alter, sign, or submit a report, and it is not a GSE, lender, agency, or portal decision.
Aria drafts from connected records, flags condition and quality inconsistencies, helps rank verified comparable candidates, and surfaces supported delivery issues. Supported answers may include source context and links when available; the appraiser reviews and commits every value.
For the supported closed-beta scenarios, AppraisalOS runs local XSD and H-1 checks on the candidate package. Official portal, Compliance Rules API, and GSE/vendor acceptance remain external steps.
