"Having Ichi as a second set of eyes for a QA/QC check on all the small details before submitting — I mean, that could save weeks on even a single project and more than pay back the cost of Ichi."

Nicole R., Project Architect · June 2026

"We view Ichi as a partner, not just another AI platform."

Mark D., Principal · May 2026

"The code lookup is faster than any other method, but we're holding off on full adoption until the Procore integration is live. That will be the real game-changer for our workflow."

Eric S., Code Consultant · April 2026

"To the extent we’ve used ChatGPT or Gemini to try to answer these code questions, we don’t get the same level of detail — and it’s not always right."

Comparison

How it compares

Compared to a generic AI like ChatGPT, Ichi offers a decisive advantage for construction and engineering: verified data. While ChatGPT provides plausible-sounding text, Ichi queries a database of over 1 million licensed ICC, state, and municipal codes, providing cited, reliable results essential for compliance. Choose a generic AI for drafting emails or general research. For mission-critical code compliance, QA/QC, and RFI reviews where accuracy can prevent costly rework and legal issues, a purpose-built, verified tool like Ichi is the only practical choice.

The decision

Is it worth it?

Return on investment

At $200/month per active user, saving just a few hours of a senior engineer's time on code research or preventing one round of jurisdictional resubmittals makes Ichi profitable for the project.

Built for

Architects, structural engineers, plan reviewers, project managers, general contractors, and real estate developers involved in design, compliance, and construction administration.

🎯

Built for

Automating QA/QC checks on construction documents and getting instant, cited answers to complex building code questions.

In-Depth Overview

For construction and engineering firms, Ichi directly addresses the two biggest non-design bottlenecks: code compliance and quality control. Instead of spending hours on manual research, your team can get instant, cited answers from its database of over 1 million official ICC-licensed, state, and municipal codes. The platform's claim of answering complex code questions in under 20 seconds is a game-changer for project timelines. Beyond code, Ichi automates the tedious QA/QC process. It acts as a second set of eyes, validating sheet indexes, flagging missing detail references, and assisting with RFI and submittal reviews. This frees up senior engineers for strategic work while improving overall accuracy. The platform's "Memory" feature is a unique solution to knowledge drain, capturing the "tribal knowledge" of experienced staff to upskill the entire team and prevent repeat mistakes. With over 99,950 code questions answered and 19,950 documents reviewed, Ichi is a proven tool for moving from concept to construction faster and more profitably.

Capture and Scale Senior Expertise

Engineering Lead

Use the 'Memory' feature to store critical project insights and standard procedures, making tribal knowledge accessible to the entire team for future projects.

Reduced interruptions to senior staff

✓ Pros

Official licensee of the ICC, providing reliable, cited code data.

Dramatically reduces time spent on manual code research and QA/QC.

Captures and distributes senior staff knowledge, upskilling junior members.

Flexible 'per active user' monthly pricing model reduces shelf-ware cost.

Data is private, encrypted, and not used for model training.

· Cons

At $200/user/month, it can be a significant cost for smaller firms or solo practitioners.

Key enterprise integrations like Procore are still listed as 'coming soon'.

Advanced automation features require a custom plan and sales demo, splitting the feature set.

⚡ Editorial Verdict

Ichi is a powerful tool for any engineering or construction firm bogged down by manual code lookups and tedious QA/QC. Its direct access to over a million licensed codes is a significant advantage over generic AI. The main trade-off is the price, which requires a clear ROI calculation, though its flexible per-active-user model is a plus.

Questions & Answers

Frequently asked questions

How is Ichi different from ChatGPT or Google Gemini?

Ichi is purpose-built for the AEC industry and uses a database of over 1 million licensed, official ICC, state, and municipal codes. This means its answers are cited and verifiable, unlike general-purpose AI which can be inaccurate for specific code questions.

Is Ichi safe and secure to use for confidential project data?

Yes, the platform states that all user data is encrypted, private, and kept confidential. It is designed for professional use within an organization.

Does Ichi train its AI on my project data or plansets?

No. According to their privacy information, your uploaded data and files are never used for training their AI models, ensuring your intellectual property remains secure.

What does 'monthly active user' mean for pricing?

You are only billed for team members who actively use the product during a given month. This flexible model is designed for the cyclical nature of project work, so you don't pay for seats that aren't being used.

Is Ichi available worldwide?

While the QA/QC and Knowledge Memory features are useful globally, the Code Compliance Copilot is specifically focused on its database of U.S. codes (ICC, state, municipal). Teams outside the U.S. should verify if the code base meets their needs.

Can I use Ichi in my country?

Ichi's primary code database is licensed for and focused on the United States. Professionals in other countries may find the document analysis and knowledge management features useful, but the core code compliance tool is U.S.-centric.
