The AI workspace for critical infrastructure teams

Put AI to work.The rules come built in.

Tacit is the AI workspace for critical infrastructure teams. It brings your rules, project context and approvals into everyday work, and it runs in our secure cloud or inside yours.

Book a 30-minute demo→scroll to see how ↓

01Regulatory coverage

Know every rule that applies to you.

Tacit maps the rules you follow, then flags what each change affects and by when.

02Planning

Every obligation gets an owner and a date.

Tacit turns each rule into tasks and books itself in for the first pass on each.

03First drafts

The work starts before anyone asks.

On the scheduled day, Tacit drafts the update with sources. A named person approves it.

04Everyday work

Anyone can ask. Tacit checks first.

Anyone can ask Tacit for help. It checks your rules and contracts before work starts.

Plan the move of our customer data to the new cloud vendor. We want it done by March.

Read the vendor contract and the new incident rules›

Two things come first:

24-hour incident notice. The new rules require it in the vendor contract. Incident rules

A data transfer assessment. Your privacy policy needs one before data moves. Privacy policy §5

The rest can start now. I added 5 tasks to the project.

For IT and security

Our cloud or yours. Your models. Your rules.

Use our multi-tenant cloud, or run Tacit inside your own Azure or AWS boundary. Models run on Microsoft Azure and Amazon Bedrock, and IT picks which ones and sets the budgets. Switch models without switching tools.

01Model makers never see your prompts
02No training without your opt-in
03Every agent action logged

APPS YOUR TEAMS BUILD

Operations built a permit tracker

Teams can build small shared apps on Tacit, using the data and access they already have. IT sees every app in one list, instead of spreadsheets it can’t.
