Meet Bob. He drafts, you decide.

Running an Etsy print-on-demand shop means five tools and five logins — and they only hand you homework. A proper listing takes 20 hours: research, design, mockups, 13 tags, pricing math. Per product. Forever. And Etsy is cracking down: over 17,000 listings were removed for disclosure violations in early 2025. Most sellers quit before their first listing goes live.

Bob is an AI agent that runs the work of your Etsy shop — trend research, original designs, lifestyle mockups, titles with 13 tags, pricing benchmarked against real comps, fulfillment routed automatically. Nothing goes live until you approve it: the gate is code, not policy. The required AI-assistance disclosure is added to every listing by code at publish — so you can’t forget. Build your first product free, no card; subscribe only when you publish.

For solo Etsy POD sellers running the shop alongside a job — people who want the store run properly without becoming the integration layer between five tools.

I build this with one designer. Daily use since July, nine feedback rounds. She sets the roadmap.

Raw 3D export of an apartment interior
Delivered photorealistic render of the same apartment
Raw export ⟷ delivered render, same camera. Real project, shown with written consent.

MATERIA — 2026render 30–90 s · room client-ready 15–20 min · 0 bytes drift outside the selection · €25/mo, 30 renders incl. · 3 free, no card

The walls come out RAL 9010, not “warm white.”

An independent interior designer pays a visualizer €1,000–2,000 per project and waits days — or hands clients raw grey screenshots. Generic AI render tools are slot machines: re-roll the whole image and hope, with no exact materials and no way to fix one wall without changing everything the client already approved.

Materia turns a raw SketchUp, ArchiCAD or Revit screenshot into a client-ready photorealistic render in minutes. Exact materials per surface — the walls come out RAL 9010, not “warm white.” Fixes are composited, not re-generated: every pixel outside your selection stays byte-identical, so approved areas never drift. €25/month with 30 renders included; start with 3 free, no card.

For independent interior designers and small studios who need client-ready visuals at the pace of client meetings — without the visualizer’s invoice.

Raw 3D export of a kitchen
Delivered render: steel kitchen with blue cabinets and red marble

Second commission, same pipeline. Drag the seam.

I sell one specific answer for $79, printed and human-reviewed. No income promises.

REPORT P.7 — RECOMMENDATION

Your business: redacted for privacy

Week 1 — $75 budget. redacted market, 3–10 hours a week, profitable and small before viral and fragile.

Runner-up routes: two named models, kept in reserve.

A real report page, specifics redacted.

One specific answer.

“I should start something” — said for six months, acted on never. Business content sounds like a scam; purpose content stops at self-knowledge and never reaches what you’d do Monday morning.

A survey grounded in five peer-reviewed psychology instruments becomes one specific recommended business and a 90-day, week-by-week plan — real budgets, honest hours, human-reviewed, delivered as a printed-quality report within 24 hours. $79 once. 14-day refund. No income promises. Ever.

For people with 3–10 hours a week, $100–2,000 they can risk over a year, and a craft or lived experience they haven’t monetized — who’d rather be profitable and small than viral and fragile.

I built Steer because the deliverable stopped telling you who’s good.

See who steers. And who gets steered.

A finished analysis tells you almost nothing anymore. A strong analyst and someone who pasted your task into an LLM hand in the same deliverable. Are you afraid candidates use AI to do your task? You should be afraid that they don’t — the job is working with AI now, and interviews, resumes and leetcode don’t measure it.

Steer gives the candidate a real task and an AI assistant inside the workspace — no webcam, no lockdown, paste allowed. It records the process, not the person: every prompt is classified as directing (they drive the thinking) or delegating (they hand it over), and a planted plausible-but-false claim — the canary — tests whether they check the AI’s output or ship it. Scored against a senior analyst’s gold-standard solution: Hire / Borderline / No, with the proof one click away.

For managers hiring data analysts and developers who want to see who steers the AI — and who gets steered.

I started with the evidence: 141 dossiers, every fact tied to a source. The site comes next.

Ką pažadėjo. Kaip balsavo.

Political accountability in Lithuania runs on memory. Promises are made in party programmes, coalition agreements and campaign interviews — then nobody systematically checks them against how the member actually voted. The data exists; no voter will ever open the formats it lives in.

Skaidriau is a free site where any voter will look up any of the 141 Seimas members: what they promised, with a working source link and verbatim quote for every promise — and how they voted, bill by bill. What can’t be verified is marked missing, never paraphrased. The evidence layer is built; the public site is next.

For Lithuanian voters. Free, no ads, no accounts, no opinions — documents only.

And last — the one I built for myself: an AI that answers to its owner and no one else.

Cloud AI vs. Luna — the trade, typeset.

LUNA — 2026fully local · zero cloud calls in operation · memory writes require your approval · agents sandboxed with hard limits
LUNA.HEFAISTUS.COM

She remembers everything. She tells no one.

Cloud AI knows you exactly as well as you should be worried about. Your questions, your documents, your patterns — stored on someone else’s servers, governed by someone else’s policy, one breach or subpoena away from public. And for all that exposure, it still forgets who you are between sessions.

Luna is the opposite trade. A full AI sidekick — voice conversations, persistent personal memory, autonomous agents that work overnight — running entirely on hardware you own. Nothing leaves the machine: zero cloud calls in operation. She remembers everything about you precisely because she can: the memory lives with you, nothing is ever written to it without your explicit approval, and every autonomous agent runs in a sandbox with hard, non-negotiable limits. Cloud assistants ask for trust. Luna removes the need for it.

For people whose context is the sensitive part — founders, lawyers, doctors, executives, anyone who wants an AI that knows them deeply and provably tells no one.

How we work

Working software beats a specification argument.

Weeks, not quarters

A working first version in two to six weeks, depending on scope. Not a slide deck about what it could be — something you can open, click and put in front of a user.

Fixed scope, agreed up front

We settle what “done” means before we start, in plain language. No hourly billing, no scope drift, no surprise invoice.

You get the whole thing

Code, database, infrastructure, deployment. It runs in your accounts, under your control. If we stop working together, nothing breaks and nothing is held hostage.

We ship, then we look at it

You review behaviour — what it does, whether it’s right — not architecture diagrams.

Who this is for

Saying who we’re wrong for makes the rest believable.

Good fit

Founders and small teams who know what they need and want it existing rather than discussed. Internal tools, marketplace integrations, AI-assisted workflows — anything where the alternative is a six-month agency engagement.

Bad fit

Projects needing a large team, ongoing 24/7 operations, or regulated infrastructure. We’ll tell you straight away if that’s you.

Commissions

Tell us what you need built

One paragraph is plenty. If it’s a fit you’ll get a reply within a day — with what we’d do first and what it would take. If it isn’t, we’ll say so and point you somewhere better.
