Speak in Hinglish. Vesper remembers your project, IS codes and QA/QC templates, checks every observation against the latest drawings, RFIs, BOQ and permits — and challenges you before it’s logged.
Built end to end on
Site managers work across a tender, a BOQ, a drawing register, RFIs, submittals, DPRs, permits and a phone full of WhatsApp voice notes. Every system unifies documents. None of them notice when they disagree.
Three truths about one column. Today the gap surfaces at rework, a payment dispute, or an incident — not when it’s spoken.
One loop, run on every observation — in the time it takes to say it.
Hinglish, noisy, interrupted. Correct yourself mid-sentence — “C-5… wait, C-6” — and Vesper follows.
Location, element, attribute, value, drawing and claimed revision become structured fields — C-5 · rebar_spacing · 180 mm · A-102 · R3.
Deterministic rules against the latest For Construction revision, RFIs, BOQ, permits and QA hold points. Not a guess — a rule.
A spoken Hinglish challenge via Rime TTS. You decide — log the observation or raise an RFI — linked to the verified drawing.
Dictation writes down what you said. Vesper checks whether it’s true — and won’t log it until it is.
Every observation is checked against the latest For Construction revision with deterministic rules. Outside tolerance, superseded revision, unsatisfied permit, unreleased hold point — each is caught and spoken back.
If a critical field — drawing, grid location, dimension — is uncertain, Vesper refuses to log and asks one precise question instead of guessing.
Upload drawing registers, specs, BOQs and method statements as PDF, Word or Excel — or just speak a briefing. Every project gets its own isolated memory, searched with vectors, BM25 and a reranker, linked in a knowledge graph, and on top of 550+ QA/QC templates referenced to IS and CPWD. Answers cite the page; weak evidence gets an honest “not in the record”.
Code-switched Hinglish, CPWD item-rate contracts and IS clause references, drill-level noise, and barge-in when you correct yourself mid-sentence. It sounds like your site because it was designed on one.
Formats, QA/QC and PMC templates indexed from InfraLens-style libraries — so Vesper knows which fields a pre-pour check or a hot-work permit actually requires.

Scripted scenarios with deliberate errors and barge-in. The bar: zero observations logged with a wrong drawing reference or dimension — and a spoken clarification for every contradiction.
Procore, Aconex, RIB and SiteSetu unify documents. The manager still correlates a spoken observation with the right revision, BOQ item or RFI by hand.

For multi-site contractors & PMCs
No per-seat surprises. Pricing depends on active sites and integrations — we’ll quote after the pilot.
Straight answers to what engineers and PMs ask first.
Bring one drawing register and one live site. We’ll load your revisions, RFIs and permits — your team just talks.
No credit card. Works on the phone your site manager already carries.
Change these whenever you like — “Cookie settings” in the footer brings this panel back.
Sign-in session, security and load balancing. The site cannot work without these, so they cannot be switched off.
