Build it Better

AI is just the kit. Cymetica is the surgeon.

Prompt and guess, and you hold the kit without knowing how to use it. Name an app: Cymetica knows how, and ships it finished.

Prompt and Guess

You hold the kit, but you are not the surgeon

With Cymetica

The Cymetica Spec

The surgeon who knows how to use the kit

Nobody looks for the holes: every key, permission and patch is yours

Security is handled: apps are read-only tools, and anything touching money gets a person's review

The agent loops or stalls, and you watch it to unstick it

Agents do not get stuck in the mud: our pipeline does the work, and an alarm sounds if an accepted build sits unstarted

Keeping up with agent tools takes expertise you would have to build

Upkeep and improvement go on continuously, with no agent for you to manage

You wire up every market and finance data connection yourself

The connections are already there: prices, news and market data from our own public API

You guess what the crowd is thinking

A social engine with Belief Networks reads public crypto communities for crowd mood and themes

No written scope, no tests

A scope you accept, a public 24 h clock, and you test it: pass, or it goes back to the queue

Start a rebuild

Tell us which financial app you use and what it should do better; our AI pipeline rebuilds it on EventTrader and you judge the result.

Paste a link to the financial app you want built better

That is all we need. Everything below is optional.

What should it do better?

Load the list from a .md or .txt file Up to 8,000 characters, one line per change.

Show us the design you want (optional)

Drop pictures here, paste a screenshot, or click to choose. We build it to match.

More options: coin, ticker, ship notice

The app's name (we read it from the link if you skip this)

Your build's coin ticker (we pick one if blank)

Your coin's name

Every build gets its own memecoin, owned by whoever asked for it. Sign in first to own it outright.

Launch its token on (optional - you can also do it later)

Your name or handle (optional)

Email for the ship notice (optional)

Build it Better runs on the Dynamic plan: you pay the measured cost of your build plus a small fee, from prepaid credit you control, with an optional monthly limit. A Pro or Max plan you already pay for also works. No ET10 holding is needed.Subscribe to the Dynamic plan →

How it works

You name the app and what is wrong with it.
We answer with the scope, including what we will not build.
You lock the scope, or ask for a change.
It goes live on EventTrader. The clock shows how long it really took.
You test it and say pass or fail. A fail goes back to the queue.
It keeps improving: tell us what to change next, and each change goes through the same scope, clock and test.

What gets built, and what does not

Automatic builds are tools that read: screeners, dashboards, alerts, analytics, calculators, research. Anything that moves money (deposits, withdrawals, placing orders, signing) is reviewed by a person before it ships. Every build says plainly what it does not do, and carries our own name and branding, never the original's.

Turn your App into a Startup

If your rebuilt app deserves a life of its own, apply to spin it out as its own startup: name, website, socials. We take a percentage of each spinoff, agreed with you in writing before anything is registered or launched. Open to accounts holding at least 100,000 ET10; nothing is charged or locked.

Build talk, yours, your AI agent's and ours, lives in its own rooms so the general channels stay readable. Every stage change on this board is posted there.
