Internal Tools
Someone describes the spreadsheet out loud — the nine fields on the form, the hidden rate tab, the rule that turns a cell red when a job runs over — and this agent builds it as a real internal tool. A form, a lookup, a calculator, a dashboard, running on your own server. Internal use only. Your sheet stays exactly where it is, so you can run both against the same numbers until you trust the new one.
Yours outright — no required subscription.
Every agent is built for your business — your systems, your approval chain, your way of working. We scope it on the call.
If this sounds too technical, don't worry. We take care of everything for you.
- Private VPS deployment. The tools it builds run on a server that belongs to you, not a shared cloud tenant, and the code sits in a repository you own. Any developer you hire later can open it without an export request.
- A technician agent alongside it. Every hire ships as a pair: the Internal Tools Agent that builds and rebuilds the tool, and a VPS-technician agent that lives on the same box and keeps it healthy — patched, backed up, monitored. You're not hiring one thing, you're hiring a small team of two.
- The first tool, built from the process you actually run. We scope one thing on the call — the intake form, the lookup, the calculator, the dashboard — and it gets built from the sheet and the rules you use today, not from a template of what companies like yours usually do.
- Security hardening. Private VPN, firewall, and encryption configured on your server before anyone on your team logs into the tool.
- Rebuilds when the process changes. You tell it what changed in March and it ships the change. That's the difference between having this and commissioning a one-off build that stops matching your process the first time you adjust it.
- 14 days of priority support after launch — the window where the exceptions living in people's heads finally get said out loud and built in.
- You own everything — the server, the code, and the tools it builds.

Who this is for
- You're a 35-person contractor and change-order pricing lives in a workbook the estimator emails around. Two project managers are quoting off different markup tables right now, and neither of them knows it.
- You're an 18-person clinic where patients fill out paper intake at the desk, the front desk retypes it, and a separate sheet tracks who's still owed a follow-up. That sheet is the only place that information exists.
- You run an ecommerce brand where support pastes order numbers and reason codes into a returns log, and a formula flags anything over a threshold for you. It quietly stopped flagging when someone inserted a column two months ago.
- You've realized the person who built the spreadsheet is leaving, and nobody left in the building can explain why cell J14 is hardcoded instead of calculated.
How it earns trust
The failure mode of AI building internal tools isn't a crash — it's a number that looks fine. It will port a stale markup into a cleaner interface and hand it back faster, which makes it harder to doubt. This is built around the opposite bet: every number traces to a rule, a person, and a date.
Every change lands as a reviewable diff
Each edit comes with a plain-language note of what changed and why. So "it started calculating differently in March" resolves to a specific change on a specific date, not a formula nobody can find.
Your spreadsheet stays intact
It never deletes or overwrites the sheet it was built from. You run the sheet and the tool against the same real inputs and compare the outputs for as long as you want — the tool has to earn the retirement of the sheet, on your schedule rather than on delivery day.
The tools show their work
Every submission is timestamped against the person who entered it, and every calculator records the inputs it used and the rule it applied, not just the number it produced. A wrong figure traces back to a person, a moment, and a rule.
None of that makes the first version right — it makes the first wrong thing findable in minutes instead of quarters.

The whole company runs on one spreadsheet and honestly I'm scared of it. Where do we start?
We start by treating the sheet as the spec — the logic in it is usually correct and worth keeping, the fragility isn't. The first version will be right about the normal path and wrong about the exceptions, because the exceptions live in people's heads and nobody says them out loud until they see the tool get one wrong. That's what the first two weeks after delivery are for.
It's too specific — there's no software that does exactly this.
That's the case for building it. Off-the-shelf software does eighty percent and asks you to change the other twenty, which is the part that makes you money. Because it's built from your rules rather than sold to a market, the specificity is the cheap part, not the expensive one.
Could it build the app our customers log into too?
No. Internal only — no public signup, no client or patient portal, nothing that takes a payment. It also never becomes the system of record for money, payroll, or medical records; if that's what you need, buy the accounting system, the payroll provider, or the medical system and let this build the small specific things that sit around them. And it never pushes a change to a tool your team is already using without a human approving it first — changes go through whoever signs off today, in the same order.
I paid a guy to build it once and now he doesn't answer.
Everything here is plain code on your server, in a repository you own, readable and handable to any developer you hire later. You own the server, the code, and the keys — we keep the recipe we used to cook it. Nothing about the tool depends on bebuilt still being around.
What happens to ten years of data in the old sheet?
It moves, but the migration is the ugly part and worth being honest about. A decade of a sheet has the same vendor entered two ways, dates stored as text, and a Notes column carrying three different meanings — it can move the rows, but it can't know which duplicates are the same thing without you telling it. Two other honest limits: it will faithfully rebuild a wrong rule if your sheet has one, and if nobody actually retires the old sheet you end up with two sources of truth, which is worse than one bad one.
What's covered under the $1,997 setup, and what isn't?
One company, one system of record, one approval chain, scoped on a free 15-minute call — and typically live about seven days from kickoff. If you want tools spanning several separate systems of record, or a different approval chain per department, that's a scoped conversation rather than a price adjustment. We'll figure out the right shape on the call.
Hiring more than one? A department on tap — the subscription puts a build team behind every request, agent after agent.
