The AI workforce for construction
The work gets done.
Ichi AI agents do the review, cite the code, and clear the admin work — drafts, documents, responses, research. You're in charge.
A demo of how Ichi works. Describe a job in plain English and Ichi drafts a workflow of task agents. For jurisdictions and plan-check reviewers, an intake workflow chains phases that each add a slice to one verified project table and flag conflicts rather than resolving them silently. For builders, a comment-response workflow reads every reviewer comment, checks each code citation against licensed ICC, state and municipal code, drafts a response and assigns it to a named person. Either workflow then runs across hundreds of projects at once, and the outputs arrive as documents and verified tables you can share, export, or connect by API.

AutoTry it yourself
Ichi saves your team hours. Every day.
Agents run workflows on your own files and know construction codes down to your municipal amendments. A few examples below — the system is flexible, and we build custom workflows around your team.
Agent workflows
12 comments, parallel agents, one response letter
Ingest comment letter
Parse each comment with its reference
Resolve cited code sections
Analyze comments against project documents
Draft a professional response per item
Recombine into one response letter
Reviewer signs off
Your volume
157 h
reclaimed every month — ≈ 1.0 full-time reviewers back on judgment calls
Assumes ~90 min per review; every workflow you add — intake, completeness, comment letters — accelerates another slice of the cycle.

“Evaluate the plans for height and stories compliance, and for fire sprinklers.”
Under non-sprinklered V-B tops out at 2 stories — the plans show 3 stories at 38 ft, so an automatic sprinkler system is required, and height stays within the 60 ft sprinklered limit of .
Your time back
Free to focus on what matters.
Agents clear the drafting, formatting, assembling, and citing in the background — on your call. Your day goes to the real issues, the quality of the review, and the community you serve.
A demo of Ichi's conversational artifacts. A code enforcement officer captures photos, a voice note and a few observations on site; Ichi matches them to the municipal code sections that apply; back at the office the notice is already drafted, with letterhead, the responsible party, the observed violation, the evidence photographs, the required corrective actions and a correction deadline. The officer asks for a shorter deadline and a re-inspection fee, and the document updates. In the second flow a plan review workflow produces a Comment Letter from its findings, and the reviewer asks for one vague comment to be rewritten with a more specific code citation — only that section regenerates. Both artifacts stay editable and cited, and can be exported or sent.

On site, hands full
One platform, both sides of the counter
The future of construction is connected.
Ichi is the only AI platform serving both the teams that design and build and the departments that review and approve — same codes, same documents, same source of truth.
The construction brain
Ichi gets smarter with every project.
And never forgets.
The limit of AI in construction isn't the model. It's what the model knows about your jurisdiction — your amendments, your templates, your past cases. That context is only captured one way: doing the work. Ichi remembers every project, and the memory compounds for everyone on it.

Ichi

Legacy permitting software
12–18 months
Deployed means live: Ichi running as your team's internal brain, workflows set up, integrations connected to the systems you already run. It's web-based and easy to learn — the benefits start immediately, and agents work around the clock, so the prep is done before the morning meeting.
* Time to first live workflow, observed across current deployments. Legacy range is typical procurement-to-go-live for municipal permitting systems.
Ichi acts as an external brain — distilling a vast amount of institutional knowledge into something that's immediately usable, clear, and grounded in real-world practice.
Deployed in the real world
Not a general AI. In the day-to-day.
The only AI platform trusted on both sides of the counter — by the jurisdictions that approve the work and the firms that submit it, including California's biggest cities and leading architecture practices.

Using Ichi as a building official really changed my life. It quite literally alleviated several pressures — and it changed the entire environment of a building department.
I can type in a question and immediately see all the relevant code sections related to it. I might even sit down with the contractor, look at the same screen together, and come up with an answer right then and there — rather than waiting two weeks.
The foundation
Codes get harder every year. Asking got easier.
Every cycle adds amendments, ordinances and interpretations — thousands of pages of PDFs nobody can navigate. Ask Ichi a question instead and it answers against the exact code groups you selected, with citations. One question can save hours of research. That foundation is live today, and it's what the agents in every workflow are built on.

Ask Ichi
Ask about the platform, a specific workflow, or how this works for your kind of organization.
Answers here are informational. Code determinations happen in the product, against licensed code books, with citations.
