Verified answers from your business data

Every number your AI gives you, computed in code and backed by a receipt.

Ground and Protect sits between your people's AI clients and your business systems. It computes and validates the figures in every answer from the source data, shows exactly where they came from, and gives your company one control plane for connections, people and policy.

Works with Claude, ChatGPT, Cursor, VS Code, Codex and any MCP client.

GROUNDED RESULTReceipt signed

“What was our revenue quarter over quarter for 2025?”

quarter	sales	change
2025-Q1	4,716,749.19
2025-Q2	4,776,220.61	+1.26%
2025-Q3	7,089,514.66	+48.43%
2025-Q4	7,076,477.19	-0.18%

Computed: sum of amount where type is sale, by quarter, with change from the prior quarter
Source: list_transactions, 20,000 rows held, all pages fetched
Receipt: signed and chained, verifiable offline

Why it matters

Language models are not calculators.

Ask a model a question over a large result and it will stop and ask how to proceed, take minutes to add up rows by hand, or, when pushed, estimate. None of those answers can be checked. Ground and Protect returns the figure in seconds, with its derivation and a receipt.

Without Ground and Protect

305 s · $0.85

The model added 1,302 amounts by hand. It was right, and there was no way to show it.

With Ground and Protect

11 s · $0.03

The same figures computed in code over every row, with provenance and a signed receipt.

One recorded run of our demo, one model, one question. Not a benchmark.

How it works

Three steps, and no new habits.

People keep using the AI client they already know. Ground and Protect does its work between the model and your systems.

1
Connect once
A company admin adds MCP services (QuickBooks, a CRM, an internal API) and, if you want, Gmail and Google Calendar. Keys and Google sign-ins are sealed inside the gateway and never shown again.
2
Install in your AI
Each person installs Ground and Protect in the AI client they already use. One install gives them every connection they are allowed to use.
3
Ask, and get verified answers
When a tool returns a large result, Ground and Protect holds the rows and computes over them. The answer comes back as a card that shows what was computed, from what, with a signed receipt.

Content validation

Answers you can check, not just trust.

Ground and Protect is a verification layer for AI answers over business data. It computes figures on request, validates the ones the model claims, and records how every number was produced.

Computed in code, not estimated

Totals, counts, groupings, comparisons and formulas are calculated by Ground and Protect from the source rows, not by the model, and the card says which rows were used.

Validate what the model claims

Send a figure the model stated and Ground and Protect recomputes it: match or mismatch within a set tolerance, with the correct figure when it is wrong.

Provenance on every card

Each answer names the source tool and call, when it was fetched, how many rows were held and used, what filters excluded, and the date range covered.

Prose checks

In clients that route the model through Ground and Protect, the written answer is checked too. Any number no card accounts for is flagged as unverified, even if it happens to be right.

Signed, hash-chained receipts

Every tool call, computed answer and admin action is signed and chained. Download them and verify offline, without trusting us. An edited receipt fails verification.

Large results stay out of the prompt

Big result sets are held by Ground and Protect instead of being pasted into the model's context, so answers over thousands of rows are fast and cheap.

Control plane

One place to govern how your company uses AI.

The Ground and Protect portal is where admins connect systems, decide who can use what, and see everything that happened. Every change is recorded and receipted under the person's name before it takes effect.

Connections, managed centrally

Company-wide, per-group or personal connections. Use one shared key set by an admin, or a key from each person. Keys are encrypted with AES-256-GCM and never returned by any API.

People, groups and roles

Invite people, organise them into groups and assign admin, manager or user roles. Each person sees only the connections they are entitled to.

Kill switch and read-only mode

Stop all AI tool access for your company in one click, or allow reads while blocking every write.

Per-tool policy and approvals

Turn individual tools on or off, mark them read or write, or hold them for approval by an admin or manager before they run.

Activity and metrics

Every tool call, grounded query, prose check and admin action, with who asked, what was computed and the result behind it.

Sign-in security

Two-step sign-in for anyone, required company-wide by an admin, and SAML single sign-on linked per company.

Google accounts and your data

Gmail and Google Calendar are read-only and per person.

When you connect Gmail or Google Calendar, Ground and Protect asks Google for read-only access to that one service in that account and nothing else. Mail and calendar data are fetched only when your AI asks a question, are held in memory for the duration of the answer, and are never written to our database, sold, used for advertising or used to train models. You can remove an account from Ground and Protect at any time, which also revokes Ground and Protect's access at Google. The details are in the privacy policy and the terms of service.
