BuildState agent kits
Three agents, on your keys and your accounts.
Ready-made agents are small programs that watch a folder, do one job when a file lands in it, and hand the result back to you. Each one runs inside a free Supabase database account you own, on AI keys you hold, so your files never pass through us. Buy once, download a zip file and follow the numbered guide. You type no code. Every tier of every kit ships the same guide. The paid tiers only add our hands.
Every price on this page is the list price. Press Buy now on a kit and Stripe checkout opens. After you pay, the download link and your key arrive by email. Signed-in members get the member price at checkout.
You will need
A Supabase account
the free database the kit lives in. Creating one takes about 5 minutes, and the guide walks you through it.
You will need
An AI key
a key from Anthropic or OpenAI. It is the password that lets the kit use an AI account you pay for yourself, usually under a dollar a day.
You will need
A folder to drop files into
the kits work on plain text files. Put one in and get one back. There is no app to learn.
You will need
About 45 minutes
the guide is numbered and has screenshots. You type no code. You copy and paste where it tells you.

The kits
01Knowledge base
The Miner
Turn every call you have ever recorded into a library of lessons that works for you.
You have had hundreds of conversations where you said something smart, and it is all sitting unread in a transcripts folder. The Miner reads them for you. Drop a transcript in a folder. Within the hour it hands back a clean file of the lessons worth keeping, with names removed, ready for your coaching product, your team wiki or your content. It runs on your accounts with your keys, so we never see your data. It filed its first lessons at 3 AM while its owner slept. Each transcript costs about 5 cents. Nothing enters your library without your approval. The machine proposes, you decide.
It runs on your accounts and your keys. We never see your data, and we can prove it, because the code is the product.
Spec
| Trigger | A .txt or .md transcript lands in its inbox folder |
| Stays quiet when | The folder is empty, so it only logs a free heartbeat to show it is alive. The file is a duplicate, which it spots and skips. The pause switch is on. The daily spending limit is reached. You set that limit, and the kit ships at $1 a day. |
| Automatic | Reading, pulling out the lessons, removing names, writing the lessons file, filing the transcript away, and logging the run and its cost |
| Always by hand | Approving lessons into your library. That never changes. |
| What you get | One lessons file per transcript, in plain text, in your out folder |
| Where it runs | Your own Supabase account, the free database the kit lives in. The guide shows you how to create one in about 5 minutes. |
| When it runs | Every hour on the clock, or on demand with one click when you want to show it off |
| What you can change | The rules for what to pull out and how strictly to remove names, hourly or daily, the daily spending limit, and which folder it watches |
Pricing

02First kit
The Content Engine
One rough thought in. A thread, a LinkedIn post and a newsletter out, in your own voice.
You do not post every day because formatting takes time, not because you lack ideas. The Content Engine takes one messy voice note or half-written draft and returns three drafts ready to publish. An X thread, a LinkedIn post, and a newsletter section with two subject lines. Your draft is the voice sample. It tightens and organizes, and it never turns you into marketing copy. It also cannot post anything, because social sites are blocked from it. You stay the publisher. Each draft costs about 4 cents. It runs on your keys and your accounts.
It runs on your accounts and your keys. We never see your data, and we can prove it, because the code is the product.
Spec
| Trigger | A .txt or .md draft lands in the content folder |
| Stays quiet when | The folder is empty, the draft is a duplicate, the pause switch is on, or the daily spending limit is reached |
| Automatic | A rewrite into 3 formats that keeps your voice, plus a notes section listing what changed and what to check |
| Always by hand | Editing and posting. It cannot post, and that is built in. |
| What you get | One plain text file with four parts, the X thread, the LinkedIn post, the newsletter section and the notes |
| Where it runs | Your own Supabase account, the same free database as the other kits. One account runs all three. |
| When it runs | Every hour on the clock, or on demand with one click |
| What you can change | Which formats it writes, the tone rules, a list of phrases to ban, how often it runs, and the daily spending limit |

03Hands-off
The Digest
The morning email that watches your machine so you do not have to.
Every business has numbers someone should check daily, and nobody does. The Digest reads your own database every morning and emails you one report. Alerts come first, in red. What failed, what quietly stopped running, what is over budget. It costs nothing in AI, because it only formats what it finds. Its best trick is catching the agent that is switched on but never ran, the failure that looks exactly like a quiet day. It was built because the founder was traveling for a month and needed the machine to report on itself.
It runs on your accounts and your keys. We never see your data, and we can prove it, because the code is the product.
Spec
| Trigger | The clock. Once a day at the time you choose |
| Stays quiet when | The pause switch is on |
| Automatic | It reads the database, formats the report and sends the email |
| By hand | Nothing. This one runs on its own |
| What you get | One email a day, alerts first |
| Where it runs | Your Supabase account plus a free Resend account, the service that sends the email. Resend sends 3,000 a month free. |
| When it runs | Daily, with a test send whenever you want one |
| What you can change | What it reports, with three reports included and custom ones needing a database query or an install call. Also the send time, who receives it, and when an alert fires |

How buying works
One zip file, no account with us
You download the kit files and the install guide. Nothing is hosted on our side, so there is no login to keep, no subscription to cancel, and none of your data passes through us.
The paid tiers add our hands, nothing hidden
All three tiers contain the same guide. The install call and the we-install option get you past the setup faster. They do not unlock anything the kit alone keeps from you.
Your keys stay yours
Every kit runs on your Supabase account and your AI keys. If we install it for you, you add us as a temporary member, and the last line of the guide is to remove our access. We never accept your keys.
Member plans are on the pricing page. Everything else that is coming is on the roadmap. Questions go to the help centre.
