Vicario - Aria

Guideline Buddy

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.

AI-powered mortgage guideline chatbot. Answers agency and non-QM guideline questions in a simple chat interface. No lender overlay research, DPA depth, or pipeline intelligence.

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.

✓Trained on Fannie Mae, Freddie Mac, FHA, VA, USDA, and Non-QM guidelines. Comparable depth on standard agency 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.

No dedicated DPA program research. Does not surface state HFA program structures, income limits, or typical credit requirements.

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.

Non-QM guideline coverage included but limited to general categories. No specific lender overlay research by deal type or lender name.

Geographic coverage

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

✓National platform covering agency guidelines across all states.

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. Company tier offers team features but context does not build across sessions.

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.

Source-backed answers with links to the original guideline document. Shows which rule applies and where to find it.

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.

No partner or enterprise API for embedding into third-party platforms.

Pricing

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

✓Free tier: 20 single-guideline + 5 multi-guideline queries per month. Premium at $12/month for unlimited queries.

No.

Surfaces deals at risk each morning

✓Rate lock expirations within 7 days, closing deadlines, and stale files over 30 days are surfaced automatically. Aria organizes your pipeline into Red, Yellow, and Momentum zones so you know exactly where to start each morning.

Pipeline delta detection

Works with any CRM export

The Bottom Line

Guideline Buddy and Aria are both mortgage-specific AI assistants built for loan officers, and the comparison is close on core guideline questions. Guideline Buddy's $12/month premium tier is significantly cheaper than Aria's $49/month -- a real advantage for solo LOs watching their tool spend. It also includes source citations and Spanish language support. Where Aria pulls ahead is depth and scope. Aria goes deeper on DPA program research across all 50 states, lender overlay research for specific non-QM deal types by lender name, and org-scoped conversation memory that builds context across your team over time. Aria also reads your active pipeline and organizes it into urgency zones -- Guideline Buddy does not do that. If your primary need is fast agency guideline lookups at the lowest cost, Guideline Buddy is a legitimate option. If you are placing complex scenarios, managing a pipeline, or closing non-QM deals, Aria is built for that work.
