Burn chart from a bank CSV
Drop the export in. It categorises, charts, and keeps every month you have ever dropped.
Never leaves the MacYou already pay for Claude Code or Codex. Ask one for a small tool and you get a folder you open once and never again. Nico keeps it running — on your Mac, on your own files, for as long as it stays useful.
The gap
A coding agent that only ever writes code is a coding agent you are underusing.
The hard part was never asking for the tool. Claude Code will write a receipt parser in ninety seconds. The hard part is everything after: somewhere for it to live, somewhere for its output to accumulate, a way to run it again next month without rebuilding it.
So the parser gets written, run once in a terminal, and lost.
The subscription isn’t worth it to me just to run a few prompts in Claude Code once a week.Hacker News
I get like $400 worth of tokens from my $20 Claude Code Pro subscription every month.Hacker News
Both of these people are right. The difference between them isn’t the model — it’s whether the work they asked for outlived the session it was asked in.
None of these are ours. Each one was described in a sentence and built by the CLI you already pay for. Every one of them touches files you would never upload to a service.
Drop the export in. It categorises, charts, and keeps every month you have ever dropped.

The one job you will never hand to a cloud service, because it is your entire camera roll.
Never leaves the MacFour years of history, answerable, without granting anyone a workspace token.
Never leaves the MacRuns before you get up. Reads what you told it to read. Sends nothing outward.
Never leaves the MacHow it works
Turn on create app and say what you want. Nico hands the job to the Claude Code or
Codex you already have installed, on your own subscription. We charge you nothing for tokens
because we never touch them.
One folder per app, outside any session. A data folder that survives every run, so
what it collects accumulates instead of vanishing. Ten versions kept, so a bad edit is not a
disaster.
Start it from a list, in a window of its own. Edit it later by asking again. Export it as a zip — without your data folder — when somebody wants the tool but not your numbers.
Your data
Every app on this page works on files you would never hand to a SaaS: the camera roll, the mailbox, four years of Slack, the accounts. That is only reasonable because the whole thing runs where the files already are.
Where it started
Hold a key anywhere on the Mac and talk. Whisper turns it into text on your own machine and the words land on the clipboard, ready to paste into the email, the commit message, the prompt. The project has been called talk, don’t type since the first day, and that is still the whole of it.
It is also how you ask for everything above. You say what you want the app to do. You do not sit down and write a specification for it.

Price
You are already paying $20, $100, maybe $200 a month for a coding agent. Nico does not resell it, mark it up, or proxy a single request through us. It runs the CLI sitting on your Mac, under the subscription you already bought.
What you are paying us for is the part nobody else builds: somewhere for those tools to live, a data folder that outlives the session, versions, exports, and an app that keeps working when the network is off.
Seven days, everything unlocked, no card asked for — and the clock starts at your first recording, not at the download, so leaving it a fortnight costs you nothing. Build something on your own files and see whether you still want it running a week later. If you do not, you keep what it made and we never had your card number.
The trial needs no card. Cancel whenever. Your apps and their data are folders on your Mac — they stay yours either way.
