The document · the position
Review: the document, and the position it supports.
Two tools that find what fails before someone else does. Witness puts a document on the stand and lets it narrate its own failure at the moment that matters. Proof assembles the evidence that a project began construction in time, with the clocks that decide it. Both compute a register in your browser before any AI is asked anything, and both leave you a file you own.
The document
Find what fails, not just what is missing
Witness — The Document Takes the Stand
Answer which provisions the document contains, pick the stress moment, and read what happens to it in its own words. The gap register is computed before anything is sent; the testimony is written by an AI briefed by Stephen Brownell.
- Live so far
- Two document types: the SNDA on a solar lease, from foreclosure to the fire, and the C&I PPA on a host’s roof, from the host’s bankruptcy to the roof coming off. Seventeen provisions and four stress moments each.
- What leaves your browser
- Only your yes, no, or unsure answers and the ids of the document type and the moment. No text is uploaded, anywhere in the tool.
- The AI step
- One call, the testimony. Usually under a minute. Nothing is stored.
- You take away
- The testimony, what the document wishes it had said, the questions to ask the counterparty, a Word export, and a share card.
The position
Prove the project began construction in time
Proof — Safe Harbor Evidence Engine
Configure the project and its beginning-of-construction path and get the requirement set, the deadline clocks, the material-assistance cost ratio, the wage and apprenticeship conditions, and the evidence binder an exam team will ask for.
- Live so far
- Both beginning-of-construction paths, six diligence overlays, and the material-assistance calculator under Notice 2026-15. Current as of July 2026.
- What leaves your browser
- Nothing, unless you run the GC Review. That sends the codename, technology, capacity, credit, method, dates, clock statuses, ratio percentages, and overlay toggles. No documents.
- The AI step
- GC Review, optional. Usually under a minute, sometimes two. Nothing is stored.
- You take away
- A Word audit binder with every requirement and its status, the clocks, and the ratio table.
What review means here
Three rules both tools keep, so that what they say can be checked and what they produce can be filed.
- Structural inputs onlyWhich provisions the document has; which method, dates, and capacity the project has. Never the document itself, never the file. Nothing you type is stored.
- The register comes firstThe gap register and the requirement set are computed in your browser and stand on their own without the AI. The AI step reads them and speaks to them; it does not replace them.
- The output is a file you ownThe testimony memo and the audit binder come out in Word, with the register inside, so the review lives in the deal file and not on a website.
When each one earns its place
Before the lease is signed, and again before the financing
Witness
A clause checklist finds what is missing. A document narrating a foreclosure finds what fails. The four stress moments are the events a lender, a buyer, or a tax equity investor will test the SNDA against, so the second reading belongs in diligence, not after it.
From the day construction begins until the credit is monetized
Proof
The beginning-of-construction position is made on a date and defended for years: at the tax equity committee, at a transfer, and at exam. The binder is built the way an agent will ask for it, and the clocks keep running after the deadline is met.
