Blend Autopilot week 3 update: Nima Ghamsari on why Blend built Autopilot, the Pre-Underwriting Summary ships to production, and smarter document validation. Autopilot weekly update: week 3. Last week Blend Labs Inc. took Blend Autopilot on the road to Las Vegas for the ICE Mortgage Technology Experience conference and caught up with many of you in person. The reception was overwhelming: lenders already running Autopilot wanted to talk about what they're seeing, and lenders who haven't yet wanted to know how quickly they could get started. While Blend Labs Inc. were there, Nima sat down with HousingWire to talk about the vision behind Autopilot. At the same time, the team kept rolling out new capabilities. Keep reading for highlights from that conversation and what's new in Autopilot this week. Nima Ghamsari on why Blend built Autopilot. At ICE Experience, Co-Founder and Head of Blend, Nima Ghamsari, sat down with HousingWire's Allison LaForgia to talk about where AI is actually delivering value in mortgage origination, and where the industry still has a long way to go. The full conversation is worth watching. Here are the key ideas. Ghamsari describes Autopilot as a system of "ambient agents, agents that are working in the background as the consumer is entering any data field, as they're uploading any document." As that happens, "Autopilot is reading it, understanding it, underwriting against the guidelines and other fraud and other kinds of things that have to be checked." The shift, as he sees it, is from rules-based automation to agents that handle complexity. "If you ask any underwriter, they say they spend all of their time on the edge cases," he said. Older automation could only handle the majority cases. With Autopilot: "We don't care what kind of document it is, we don't care what kind of data it is, we don't care how complex the person's income is. We're going to solve this for you." On consistency: "You don't want AI to hallucinate." After running his own complex financial profile through the system repeatedly, "I ran it through 100 times, I got the same exact answer from the AI every single time." And on where this is going: "Every single consumer has a very personalized, very tailored experience that's generated on the fly for them." The goal is to make "the underwriters and processors and the consumer... 100x more efficient." The pre-underwriting summary now ships in the product. Two weeks ago, Blend Labs Inc. introduced the Pre-Underwriting Summary: a structured PDF that distills every finding, calculation, and recommendation into one document. Blend Labs Inc. shared it with lenders and started collecting feedback. This week, it ships into the product, with significant enhancements based on what Blend Labs Inc. heard. The summary PDF now renders full income calculation breakdowns directly in the document. When Autopilot calculates qualifying income from a W-2, Schedule C, or K-1, the PDF shows every step: the formula, the inputs, the result, the unit, and the guideline citation. For a self-employed borrower where the agent averages two years of Schedule C income, subtracts business use of home, and adds back depreciation, each of those operations is laid out in the PDF itself, not just referenced. Income calculations now also carry GSE reference IDs, so every number in the summary is traceable back to the specific guideline rule that produced it. For underwriters, this means one document with everything: findings, methodology, and audit trail. For compliance teams, every calculation is citation-linked and reproducible. Preview to production in two weeks. That's the pace. Document validation is smarter and more transparent. Two improvements this week to how Autopilot handles document review. First, the document classification and validation prompts have been significantly improved. The agent is now more accurate at identifying document types and catching issues, particularly for edge cases where documents are incomplete, mislabeled, or not what was requested. Second, when a document doesn't pass validation, the borrower now sees specific reasons why. Instead of a generic "please re-upload" message, the borrower gets actionable feedback tied to what was actually wrong with their submission. Wrong document type? Missing pages? Illegible scan? The system tells them exactly what to fix. This matters because vague document requests are one of the biggest drivers of borrower confusion and follow-up abandonment. Specific, clear feedback means faster re-uploads, fewer support calls, and fewer loans stalling on document collection. Loan officers now see a full Autopilot activity history. When Autopilot processes documents, creates follow-ups, calculates income, and resolves tasks on a loan, every action is logged. Loan officers could already see this activity, but on complex loans with many documents and borrower interactions, the list could get long. The agent activity feed now supports full pagination. Loan officers can scroll through the complete history of what Autopilot did on a loan, from first document to latest follow-up, without hitting a wall. For operations teams processing high volumes, this means complete visibility into agent behavior on every loan, no matter how many actions were taken. Improvements under the hood. Beyond the headline features, the team shipped a series of quality, reliability, and infrastructure improvements this week: * Per-lender feature flags: Autopilot now supports tenant-based feature flags with automatic updates, giving lenders granular control over which capabilities are active in their environment. * Expanded evaluation coverage: New eval scenarios for wrong-document detection (incomplete and dummy uploads) and bank statement account ownership verification. These evals run continuously to catch quality regressions before they reach production. * Summary generation reliability: Fixed edge cases that caused summary PDF generation to fail in certain sandbox configurations. * Asset data pipeline: Restored asset data fetching in application data retrieval, ensuring the agent has complete financial context when processing documents. * 10+ internal improvements across CI pipelines, test coverage, tracing, and code quality. What's coming next for Autopilot. Four new capabilities and a full slate of reliability improvements this week, shipped while the team was on the road at ICE Experience. The reception from lenders has been strong. Dozens of lenders have activated Autopilot since launch, many self-serving directly into production without an onboarding call. The conversations at ICE Experience reinforced what Blend Labs Inc. is seeing in the data: lenders want this, and the ones who've turned it on are seeing results immediately. Looking ahead, Blend Labs Inc. is continuing to expand what Autopilot understands. Credit analysis, pricing, fees, and DU results are on the roadmap, giving the agent a fuller picture of each loan. And borrower chat is coming, where borrowers can interact with the agent directly about their loan, their documents, and what's needed next. Every improvement ships automatically to every lender with Autopilot activated. No upgrade cycles. No implementation projects. The agent gets better every week. Blend Labs Inc.'ll be back next Wednesday with what's new. Blend Autopilot is currently in preview and free to activate and use during the preview period for all Blend customers. To get started, visit your Lending Config Center or contact your Blend account team. Blend Labs Inc. publish a new update every Wednesday.

Blend Labs has launched Blend Autopilot, an AI agent that completes mortgage loan origination reviews in 15 seconds. The tool reviews borrower documents and application data in real time, performs compliance checks, generates follow-ups and updates application fields automatically. Traditional mortgage origination takes 30 to 60 days and costs over $11,000 per loan. Blend Autopilot addresses delays by responding instantly when borrowers upload documents or complete applications, particularly outside business hours when 53% of borrower interactions occur. The non-decisioning tool automates document review whilst leaving credit decisions to underwriters. It is currently in preview and free to activate for all Blend platform customers through a single toggle in the Blend Lending Config Center. Blend says the tool improves borrower experience by reducing unnecessary documentation requests whilst maintaining consistency across loan reviews.
