Anthropic, OpenAI, Moonshot and more, one login
New models arrive the week they ship. Pick a model per request, per person or firm-wide, or leave it on Auto to route each request for speed and token cost.
Architecture and construction
One AI workspace for the whole practice, with the codes and contracts built in.
Tacit is the AI workspace for critical infrastructure teams, including the firms that design hospitals, labs and campuses. It turns meetings and site photos into reports, and checks codes and client contracts before work goes out.
No mandate, no rollout plan.
- people in NBBJ’s first pilot, with no mandate
- 15
- people on the firm-wide contract that followed
- ~600
The AI your people actually keep
IT sets it up once. Everyone uses it.
Teams, Slack, email and the browser
No new tool and no prompts to learn. Connecting Microsoft 365 takes about five minutes.
Decisions don’t stay trapped in one meeting
Meetings, emails and chats flow into one context for people and agents, so the whole project team can find what was decided and why.
Compliance and safety reports from site data
Tacit drafts 90-page reports from hundreds of site photos and data tables, with every figure linked to its source.
Your models, your budgets
IT chooses which models run and sets token budgets by team. A failed call retries on an approved fallback, and every agent action is logged.
The model makers never see your data
Models run on Microsoft Azure and Amazon Bedrock, where the companies that make them never see your prompts or train on them. We train only with your written opt-in. SOC 2 Type II, with a CASA/ASVS assessment on record.

Turn yesterday’s site walk into the weekly safety report.
Draft ready: 34 pages from 212 photos.
I sorted the photos by level and trade, matched them to the open snag list and wrote up the 6 new issues. Every finding links to its photo.

What did we agree with the client about the atrium glazing?
Cut it to 40%, agreed in Tuesday’s design review.
The client accepted the lower glazing ratio to stay on the energy code’s prescriptive path. Kate is updating the elevations by Friday.

Revision C changed the stair width. Your contract needs fire engineer approval before drawings are issued.

Compliance, built in.
IBC, IECC and ASHRAE 90.1, as adopted locally
Tacit knows which edition and local amendments each jurisdiction uses, and flags design choices that won’t meet them.
Fire strategy and sign-off
Revisions that touch egress, stairs or compartmentation go to the fire engineer before drawings are issued.
Healthcare, labs and campuses
Guidelines such as the FGI Guidelines for hospitals, tracked for the building types you design.
Scope, approvals and confidentiality
Each client’s approval steps, deliverables and data terms tracked against the schedule, so nothing goes out before it should.
Examples, not the full list. Tacit tracks many more rules than we can show here.
Chosen by NBBJ.
Tacit started with 15 people, no mandate and no rollout plan. Colleagues saw what it did and asked for a seat. Six weeks in, leadership asked to roll it out across the firm of about 600. The firm-wide contract is signed.

Frequently asked questions
Which models can we use?
Anthropic, OpenAI, Moonshot and other leading models, all under one login and running on Microsoft Azure and Amazon Bedrock, with new models added the week they ship. IT decides which are allowed, and people can pick one per request or leave it on Auto.
How does IT control it?
IT chooses the models, sets token budgets by team and sees spend as it happens. Every agent action is logged, and connecting Microsoft 365 takes about five minutes.
Does it know which code edition applies to each project?
Yes. Tacit tracks which editions and local amendments each jurisdiction has adopted, and uses each project’s location, building type and program to work out which apply.
Where does our data live?
In our multi-tenant cloud, with each customer’s data isolated, or inside your own Azure or AWS. Models run on Microsoft Azure and Amazon Bedrock, where the companies that make them never see your prompts or train on them. We train only with your written opt-in.
Does Tacit sign anything off?
No. Tacit checks, drafts and flags. Licensed professionals on your team approve and sign every issue.
