The AI plan-check coach that actually reads your plans.
Assist Now opens any flagged correction, sees your actual sheet, and explains the fix in plain English. When you're ready, paste your proposed change and get a strict plan-check review before you resubmit. Stop spending weeks decoding city comments.

The current reality
Three to five resubmittal cycles. Six weeks each. Every project.
Decode the comment
"Provide compliant egress analysis per CBC §1006." OK — what does compliant actually mean here? You spend a day re-reading code.
Build the fix
You sketch a fix, add notes, redline the sheet. You're not 100% sure it'll satisfy the reviewer. You ship it anyway.
Wait six weeks
The city sends back a new round of comments. Sometimes the same correction comes back differently worded. You start over.
How Assist Now changes that
Three loops. Each one closes a hole that's costing you weeks.
Plan-aware grounding
When you ask a question about a finding, Claude doesn't answer from generic code knowledge — it pulls up your actual sheet. It can say things like 'on your sheet, the fire-rated assembly callout at gridline B is missing the UL listing reference' instead of vague advice you have to translate yourself.
→ Open any finding to start
Validate-my-fix
Before you commit a fix to the plans, paste your proposed change. Assist Now acts as a strict city plan-checker and returns a verdict (compliant / partially compliant / non-compliant) with specific concerns. You catch the gaps before the city does.
→ One pass, no resubmittal cycle
Resubmittal mode
Got a correction letter back from LADBS? Paste the whole thing. Assist Now breaks it into individual corrections, prioritizes by severity, and walks you through fixing each one. Track what's resolved as you go.

Why this isn't just "ChatGPT for plans"
ChatGPT can answer code questions in the abstract. It cannot see your project, your sheet, or the LADBS-specific interpretation that gets you approved.
Every chat opens with your actual rendered PDF as context. References are spatial: 'top-right title block', 'section detail at gridline B' — not generic.
Per-city code data, kept fresh weekly. LADBS, LA County, Beverly Hills, Santa Monica, plus 200+ more. Generic AI answers California Building Code; we answer your city's adopted version.
Every turn persists. Open the bubble tomorrow, the conversation picks up where you left off. No re-explaining context to the AI.
Pre-submittal verdict on your proposed fix. Get the strict reviewer look before you pay the city to give it to you.
Paste the whole correction letter, get a structured walkable list. No more sitting with a PDF scan and a highlighter for two hours.
Speaks code citations, assembly types, occupancy classifications. Never has to ask "what does V-A construction mean?"
A real conversation
From a finding on a 2-story Beverly Hills residence (CBC §420 fire separation, page GR-2):
- Top section: Window installation details (6 isometric views showing window frame, building paper, and flashing configurations). These are opening-protection details, not fire-separation assemblies.
- Right side: Two green-building forms (GRN 11R and GRN 14) with compliance checklists.
- Title block: Confirms this is the Notes & Forms sheet for the Alpine Drive custom residence.
You're missing the fire-rated wall and floor/ceiling assembly details required by CBC §420. For a 2-story residence with basement, you need to show the 1-hour rated assembly between basement and 1st floor with UL listing reference, gypsum thickness, and firestopping callouts.
- 2x6 wood studs at 16" o.c.
- 5/8" Type X gypsum board on each side
- R-19 mineral wool insulation (filling the cavity)
- Firestopping at all penetrations (sealant, putty pads at electrical boxes <100 sq in)
Add a wall section detail referencing UL U419 and a callout table listing the assembly components. I can validate your draft if you paste it back into the "Validate my fix" tab.
