Five modes
One product with the five modes review work needs.
Code Check
Reviews drawings and application documents against your chosen set of laws and ordinances. Every finding comes with a cited provision.
Checklists
Bring your own checklist (CSV/Excel) as it is. The AI judges each item as compliant, non-compliant, or needs review.
Site Survey
From an address and building conditions, lists every applicable regulation with citations and exports a checklist to Excel. Site information takes about 5 minutes; regulation research 25–45 minutes.
Knowledge QA
Register internal manuals and technical standards as collections and get cited answers to your questions (PDF/PPTX supported).
Explore
Ask drawings and documents anything, with the relevant pages highlighted and saved.
Create & Automate
Deliverables and routine work, too.
From rendering generation to templated procedures, hand the work around review to the AI as well.
Rendering
Generates architectural renderings by transferring the textures and tones of your reference images.
Image Studio
Ask in plain language for partial edits, replacement, sketch to photoreal, elevation to rendering, outpainting, video, and upscaling. Chain multiple edits and browse a per-case gallery.
Style Library
Register sets of reference images and call them up — "in this style" — for repeatable production.
Workflows
Turn sequences like site survey → code selection → drawing review → human approval → notification letter into templates and run them repeatedly.
Review workflow
AI drafts. People decide.
One flow from reviewing findings to re-checking revised drawings and managing cases.
Review
AI drafts, people decide. Filter findings by severity and status, highlight the relevant part of the drawing, and export only approved findings to reports.
Re-check
Automatically matches revised drawings against previous findings and classifies each as resolved, unresolved, or new. Exports correction notices to Word/Excel.
Cases
Manage drawings, documents, and run history by case. Filter by tags, bulk-download multiple cases, register merged PDFs, search across cases, and get notified when long jobs finish.
Accuracy & trust
The more you use it, the closer it gets to your standards.
Operate with measurable accuracy while your organization's review expertise accumulates in the AI.
Accuracy
Correct/incorrect feedback on each answer and finding feeds directly into accuracy improvement and evaluation, visualized over time. Supports regression testing on evaluation sets with ground truth.
Learning
Register drawings with their actual review results, and they feed reference cases and evaluation data. The more you use it, the closer it gets to your organization's review standards.
Admin
Per-case sharing (owner/editor/viewer), role-based feature permissions, account approval, audit logs, SSO, and Japanese/English UI.
