Mortgage & Title-Processing AI Agent
Index loan and title documents, reconcile them against the conditions list and compute candidate TRID dates — the licensed originator, the settlement agent and the title underwriter keep the acts that are theirs.

What this agent does
Handles the document layer, not the licensed acts
In
- 01
Index loan and title documents from supported origination, point-of-sale, title-production and eClose sources.
- 02
Index every document against the conditions list, so what is outstanding is visible without re-reading the folder.
Reason
- 03
Extract recorded-instrument data — parties, dates, book and page — carried with the instrument each field came from.
- 04
Extract the six items that complete an application, and raise the sixth as an event, because it starts the federal clock.
- 05
Extract the beneficial-ownership data an entity or trust transfer would need, while the FinCEN filing action stays gated.
Decide
- 06
Reconcile received documents against the conditions list, and flag the gaps rather than clearing them.
- 07
Reconcile candidate TRID dates against the business-day convention, with the receipt basis shown beside each date.
Out
- 08
Route terms, disclosure release, clear-to-close, adverse action and disbursement to the licensed role that owns each.
- 09
Execute write actions only inside the approval boundaries agreed during implementation.
Product statement
The SAFE Act keeps the application and the terms with the licensed MLO; disbursement stays with the settlement agent, the commitment with the title underwriter.
Example workflow
One file, intake to licensed review
- 1File documents receivedLOS folder, point-of-sale upload, title order or county index
- 2Evidence assembledInstrument data, the conditions list, disclosure history and the dates each one rests on
- 3Package proposedIndexed documents, dates and confidence
- 4Controls appliedHeld-act checks, six-item application detection, LE and CD window checks and the confidence threshold
No human action required
Stages 1 to 4 run unaided and none of them releases a disclosure — a lost three-day window costs re-disclosure and delay, so the licensed lane opens at the confidence gate.
Goes to the role that owns the act.
Adds a compliance read first.
Licensed review
The file is held with its evidence, the basis for each date and the confidence.
Approve · Correct · Escalate
Approved — handed to the owner of the act
- 6Loan and title systems updatedOnly where write access and approval policy allow it
- 7Outcome evaluatedDate-basis accuracy, condition rework, corrections and post-closing QC findings
Corrections
Every reviewer correction is counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Presenting or negotiating any loan term.
- Taking an application or accepting the sixth item.
- Releasing a Loan Estimate or Closing Disclosure.
- Determining consummation readiness or clear to close.
Automation boundary
Agent acts unaided
- ✓Intake, classify and index loan and title documents as they arrive.
- ✓Extract instrument data without characterising effect.
- ✓Reconcile received documents against the conditions list.
- ✓Compute candidate TRID dates and show the basis for each of them.
Writes run only inside the boundaries agreed at implementation, never ahead of the act.
- Issuing an adverse-action notice or its stated reasons.
- Communicating with an appraiser or AMC about value.
- Issuing a title commitment, policy or opinion.
- Authorising or releasing an escrow disbursement or wire.
Example output
One search extract, annotated
Everything the agent extracts is attached to the instrument it came from.
Search-extract output · single file
Illustrative example- Transaction
- Refinance, one owner
- Extracted line
- Deed of trust in favour of the named lender, parties and dates as written
- Book and page
- Bk 4182 Pg 77
- Source of record
- County recorder index
- Confidence
- 93%
- Characterisation
- None — reserved to the underwriter
As received
Read from the recorded instrument and the county index — nothing on this side is characterised by the agent.
Source documents used
- Recorded instrument
- County recorder index
- Prior title file
Why no opinion
Summarising a search is not rendering an opinion on the title.
What the score decides
Below the threshold the extract picks up a compliance read before review.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Every file
From the loan and title systems
Index against the conditions list
Work from the documents on file, the conditions list and the recorded instruments behind them.
Clear conditions, keep the clock
Indexing, extraction and condition reconciliation arrive already done.
Send review to the licensed acts
Held acts and low-confidence extracts are marked, so licensed time lands where the exposure concentrates.
Build an evidence trail
The extract, its source instrument, the reviewer and the timestamp travel with the loan file.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Observability & evaluation
- OpenTelemetry

- Supported monitoring/evaluation sources
Integration availability depends on the client's existing systems and API access.
Agent controls
Six layers between the model and the file
Each control wraps the one inside it. Downstream cures are bounded and time-limited; what a layer misses is named in the failure-mode map below it.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether the package may stand
- L3
- Puts the act in a licensed hand
- L4 – L5
- Keep the record and the version honest
- L6
- Pulls the agent back when signals degrade
How Nestack evaluates it
Evaluate the whole file workflow — not only the finished extract.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the file the examiner sees
- E1Final-output evaluationDid every extracted field match the instrument it cites?
- E2Step-level evaluationDid it apply the three-business-day LE and CD windows to the right dates?
- E3Tool evaluationDid it read and write the correct file and the correct field?
- E4Confidence calibrationDo low-confidence extracts actually attract more corrections?
- E5Slice evaluationHow does performance change across specific loan and transfer types?
- E6Business outcomeHow many files needed rework or a correction after closing?
Floor — the outcome the lender answers for
Failure modes
Where each failure originates in the agent
Seven failure modes, placed at the stage each one originates.
Agent lifecycle
Direction of processing →
01 · Retrieval
1 mode
- TT-01
Superseded document read
Value taken from a prior-version appraisal in the repository.
Stage gathers
Loan documents, title instruments and rule versions
02 · Reasoning
2 modes
- TT-02
Tolerance bucket misread
A written-list fee at zero tolerance is scored against the cumulative bucket.
- TT-03
Denial reason not from the record
Drawn from feature weights, not the specific principal reason §1002.9(b)(2) requires.
Stage proposes
Indexed documents, dates and confidence
03 · Tool / write
2 modes
- TT-04
Redisclosure trigger missed
A revised date is written without re-testing the APR, product and penalty triggers.
- TT-05
Segregation of duties broken
Conditions-cleared is posted while reconciliation access is still held.
Stage writes
Only where write access and approval policy allow it
04 · Output
1 mode
- TT-06
NPI sent to a spoofed address
A closing package carrying SSNs leaves the 16 CFR 314 boundary.
Stage returns
The package the reviewer approves and files
05 · Change / Version
1 mode
- TT-07
Filing posture out of step
Gating still runs pre-vacatur FinCEN logic, or does not resume if the appeal revives it.
Stage tracks
Model, prompt, rule versions and filing posture
- Sev-1 · a held act runs unaided
- Sev-2 · a wrong field reaches the file
- Sev-3 · source degrades, file routes to review
Affected slices
Overall quality can hide one bad cohort
The all-loan timing-defect rate is the baseline every row here is read against; three cohorts sit above it and two clear the review threshold. Nestack reports the rate by slice, not only in total.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Non-QM, self-employed and investor-entity | 9.9% | 3.8× | Review | |
| Attorney-state and entity/trust transfers | 6.5% | 2.5× | Review | |
| Construction-to-perm, renovation, ARM/HELOC | 3.9% | 1.5× | Watch | |
| Conforming fixed-rate purchase, W-2 | 1.3% | 0.5× | Normal |

2 of 4 slices over threshold
Evidence-linked improvement
A cycle closes with a new regression case
Nothing closes until the failure has been written as a case the next release must pass, and detection afterwards is measured against that longer suite.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
TRID timing-defect rate rises in a loan cohort.
- 02
Diagnose
Where the rate holds above threshold, the files and their date bases are read until one cause remains.
- 03
Improve
The fix is written against a rule version, with the defective files attached.
- 04
Verify
Nothing ships until the affected regression cases pass again.
- 05
Learn
The case joins the permanent suite and the lender's condition rules.
Learn → Detect
The return edge. The next detection runs against a suite that is one case longer.
Typical build scope
