Changelog

Major underwriting upgrade: compile general ledgers and financial statements into a T-12 with source provenance, plus clearer product and security documentation for customers.

• Build a ledger-built T-12 from uploaded financial documents with click-through provenance to the source PDF
• Verify T-12 sources workbench with editable line items, Manual Total overrides, and vault integration
• Rent-roll extraction improvements (Base Rent Due preference, scanned/rotated roll handling)
• Public product documentation at slung.com/docs and an updated Security page at slung.com/security
• Rent comps serving controls (recency window, proximity-based self-exclusion, clearer Available labels)

Underwriting edits feel snappier in the web grid, rent comps are easier to trust, and brokers can bring deals in from external deal rooms.

• Compiled model engine for the in-browser underwriting grid — much faster edits with formulas preserved
• Model Templates management in the app; templates live outside the document vault
• Vault-first document ingestion and clearer property dashboard flows when docs are still processing
• Rent comps address/name display fixes and serving-window improvements
• Deal-room acquisition pipeline for claiming and processing broker deal-room opportunities (rolling out)

Plans and usage gates landed in the product, production email underwriting with Sam matured, and the institutional model grid became the default underwriting surface.

• Pricing tiers, subscription selection, and usage banner in the web app
• Stripe billing for Principal plans and deal overages
• Production cutover for underwriting by email with Sam at sam@slung.ai
• Univer-powered underwriting grid with native deal pricing and worker-backed formula calculation
• Share-link and DataRoom improvements (docs carried through reshare chains; clearer link-only DataRooms)
• Public Security page describing encryption, infrastructure, access, and compliance posture

Sam’s email replies became more conversational and useful for day-to-day deal work, with safer routing and faster paths into a model.

• Conversational daily/weekly briefs in Sam’s voice
• Inline property links in agent email replies
• Quick-entry underwriting flow to synthesize a T-12 and get into analysis faster
• Reply-all and run-scoped routing safety for multi-party email threads

Email underwriting scaled with polling, rate limits, and stronger PDF/OM and rent-roll processing behind the scenes.

• Dedicated email polling for inbound underwriting messages
• Per-user rate limiting on email intake
• Stronger T-12, OM, and rent-roll task limits and PDF extraction (including OM image extraction)
• Unit-mix add/delete and share-feature updates in the dashboard

Deal workflow quality-of-life: multiple reports per address, clearer account agreements, and better export/share timing.

• Multiple reports for one address rolled into a single property entry
• Terms of Service and Privacy Policy acknowledgment during account creation
• Save, assumption sliders, and drag-and-drop upload polish
• Export and email-share timing improvements

Platform hardening for reliable production use — verified accounts, safer APIs, and cleaner property data ownership.

• Email verification for new accounts
• Property operations keyed by property ID (not address string)
• CORS and Maps configuration for production deployments
• Security headers and query-safety release prep

Expense and income categorization became easier to review and correct before you rely on the model.

• Refined income/expense classification with uncategorized items surfaced clearly
• Amount-difference column for reconciliation
• Address autocomplete and classification skip controls in the UI

Early analysis surfaces expanded beyond the raw T-12 into insights and richer property characteristics.

• Slung Insights for deal-level takeaways
• Investor Report feature for shareable deal summaries
• Year built and stronger lat/long property context
• Lead and table interaction improvements in the web app

The product that became Slung shipped its first end-to-end underwriting loop: upload a T-12, categorize line items, and work the model in the browser.

• Magic-link account creation as the primary signup path
• In-browser spreadsheet-style T-12 review and editable totals
• LLM-assisted row categorization and property characteristic inference from address
• Google Places address autocomplete and concurrent T-12 processing via background workers
• Benchmark analysis columns and sticky T-12 viewing
• First production front-end and back-end deployments
