Vicario - Aria

Zeitro GuidelineGPT

Core product type

Mortgage scenario AI. Describe any borrower scenario and Aria returns a practical answer: qualifying logic, program options, which lender to call, and state-specific DPA availability.

✓Mortgage scenario AI trained on agency guidelines and lender documentation. Similar positioning to Aria.

Guideline training

Trained on Fannie Mae, Freddie Mac, FHA, VA, and USDA guidelines. Aria handles DTI edge cases, AUS strategy, condo project review, employment gap scenarios, and agency differences.

✓Agency guideline training. Handles conventional and government loan scenarios. Comparable depth on standard guidelines.

DPA program knowledge

✓State HFA programs across all 50 states. Aria knows program structures, income limits, and typical credit requirements for CHFA, MassHousing, SONYMA, Florida Housing, TSAHC, TDHCA, and more.

Limited DPA program knowledge. State HFA program depth is narrower than Aria.

Non-QM and lender overlay research

✓Aria researches deals against specific lenders by scenario type: bank statement (Angel Oak, A&D, Acra, LendSure), DSCR (UWM Investors Flex, Acra, Defy), ITIN/foreign national (Acra, A&D), and fix-and-flip. You make the call.

Lender-specific guideline access through some lender partnerships. Non-QM overlay research is less developed.

Geographic coverage

✓Agency guidelines and DPA programs for all 50 states. Lender overlay research is not restricted by geography.

Zeitro has been in market longer with broader lender partnership coverage.

Org-scoped conversation memory

✓Every LO at the same organization shares Aria conversation history. Context builds across the team so Aria gets more useful as the org uses it.

No org-scoped persistent memory. Context does not carry between sessions or across team members.

Confidence and hedging

✓Aria explicitly signals uncertainty when guidelines are evolving or lender-specific. It names the specific action to take (call the AE, verify with the HFA) rather than leaving the MLO without a next step.

Confidence signals are present but less calibrated for lender-specific vs. agency-level uncertainty.

Enterprise and partner API

Stateless partner API with per-key monthly query caps. Designed for lenders and platforms that want to embed Aria into their own tools.

✓Enterprise access available. Lender integration focus.

Pricing

Individual access at $49/month. Enterprise pricing on request.

✓Pricing not publicly listed. Enterprise pricing on request.

Pipeline Intelligence

Reads your active pipeline

✓Connect your CRM via API or upload a CSV export. Aria reads your current pipeline and delivers a morning brief on what needs attention today.

No.

Surfaces deals at risk each morning

✓Rate lock expirations within 7 days, closing deadlines, stale files over 30 days, and competitor credit inquiries are surfaced automatically in a daily brief.

No.

Flags competitor credit inquiries

✓Aria monitors for credit inquiries from competing lenders across your active pipeline files and alerts you before deals leave.

No.

Works with any CRM export

✓Upload a CSV from any LOS or mortgage CRM. Encompass, Calyx, LendingPad, BytePro, Floify, Shape, and BNTouch all work out of the box. No integration project required.

No.

Time in market

Aria launched in 2025. Shorter track record than Zeitro.

✓Zeitro has been in market longer with more usage history and lender relationships.

Knowledge curation

✓Aria's knowledge base is actively maintained. Gaps are flagged, reviewed, and resolved by the team. The more it is used, the more precise it gets.

No structured knowledge curation pipeline.

The Bottom Line

Zeitro GuidelineGPT and Aria are the most direct comparison in this set - both are purpose-built mortgage scenario AIs. The key differences are depth and memory. Aria goes deeper on DPA program research (50 state HFA programs with typical income limits and structures), lender overlay research (specific non-QM lenders by deal type), and confidence calibration (explicit hedging when information is likely lender-specific or subject to change). Aria also builds org-scoped conversation memory so context accumulates across your team. Zeitro has been in market longer and may have lender relationships that give it access to specific guideline documents Aria does not have. Both tools are materially better than general chatbots for mortgage scenario work. Aria is the only tool that knows every guideline, every lender overlay, and every deal in your active pipeline.
