FOR ARCHITECTS & ENGINEERS
The first AI-native document platform for the built world.
The design lives in the model. What gets permitted, bid, and built is the set. Between the two, things get lost. Subtillis functions as the layer in between. It reads every sheet, spec, and schedule in the record, catches what drifted, and answers any question in seconds, with the pages to prove it.
Everything the set knows, one question away
Hundreds of sheets, thousands of references, all supposed to agree. Subtillis keeps drawings, specs, RFIs, and submittals in one tracked record, reads every page, and answers any question with the sheet that proves it.
EACH SPOKE FEEDS THE RECORD. THE RECORD FEEDS EVERY SPOKE.
Drawing review, before the set goes out
Tags against schedules, drawings against specs, revision against revision. Subtillis reads the whole set, flags what disagrees, and cites the sheets that prove it, while an error still costs an hour instead of a change order. The review, and the stamp, stay with your engineers.

RFIs, answered from the record
Most RFIs are questions the set can already answer. Subtillis finds where the answer lives and drafts the response, so an engineer reviews instead of researches.
Logged as it lands
Every RFI enters the record with its full history attached.
Sheets pulled
The drawings and spec sections in question, gathered automatically.
Response drafted
A first draft from the record, ready for an engineer to edit and send.

Door 214A hardware set conflicts with the schedule. Which governs, the plan note or A-601?
Schedule A-601 governs. The note on A-201 predates Rev C; hardware set HW-3 applies per spec 08 71 00, 2.4.
Submittals, checked against your own specs
Each submittal gets a first pass against the specs it claims to meet. What deviates gets flagged with the section that proves it, before anyone spends an afternoon on page one.
