Your apps. On your device.
With the open Ara-Kit you build apps from forms to AI agents, and Arasul runs them on your device.
What an app is on Arasul
An app is not a plugin sandbox but a package with four parts, and the device itself dictates its shape.
A manifest
Every app ships an app.json: name and version, the memory and CPU it gets and the models it may use. The device reads it on rollout.
A page
Arasul serves the frontend under /apps/<name>/. Whoever is signed in and has the app released sees it in the left rail, nobody else does.
A container
The backend runs as its own container on the device. Arasul hands it the signed-in person, so the app never has to build a login of its own.
Flows in the same package
A flow is a markdown file next to the app, versioned with it. It runs traceably and can pause until a human approves.
What you can build on top
A few concrete examples. Open them up. What is possible is decided by your needs, not by a catalog.
Quote assistant for trades
Situation
Quotes get written in the evening, once the job site is done. Two hours of typing from the measurements, then looking up prices again. Whoever answers faster wins the job.
How it runs
- 01The fitter photographs the measurements and drops them in a folder on the device.
- 02An agent reads out the line items, quantities and materials included.
- 03It calculates with your own price list, not with list prices from the web.
- 04The finished quote lands as a PDF in the customer folder, for review before it goes out.
What it gives you
The quote goes out the same day instead of on Friday. Your pricing stays on the device in the workshop and goes to no provider.
Requests from the inbox
Situation
The shared inbox gets everything: real requests, invoices, ads and reschedules. Someone has to sort it every morning, and the urgent request gets lost in the pile.
How it runs
- 01Arasul pulls the mail from the inbox you already use.
- 02An agent sorts by type: request, invoice, appointment or the rest.
- 03For each request it searches your records for whether the customer is known.
- 04Standard cases get a draft reply, the rest is routed to the right person.
- 05Nothing goes out that someone has not approved.
What it gives you
The inbox is sorted in the morning instead of full. The mail traffic stays on your device, because the model computes locally.
Deadline checks for law firms
Situation
Notice periods sit somewhere on page eleven. Miss one and you are liable. So someone reads them by hand, on every new contract.
How it runs
- 01New contracts land in a watched folder.
- 02A workflow searches them for deadlines, terms and renewal clauses.
- 03Every find is noted with its source location, so you can double-check it.
- 04The dates move into the firm calendar, with lead time for a reminder.
What it gives you
No more deadline that lives in one person's head. Built once, the same app runs in every firm.
Invoice and receipt processing
Situation
Receipts arrive as a photo, as a PDF, as a scrap of paper in a shoebox. Accounting types them up, and half of them are still missing at month end.
How it runs
- 01Receipts get photographed or dropped in by mail.
- 02An agent reads out amount, date, tax rate and supplier.
- 03It reconciles against open items and flags what does not match.
- 04Outgoing invoices are created directly as ZUGFeRD, so machine-readable.
What it gives you
Accounting gets clean data instead of a stack. Revenue and customer data stay local on the device.
Two systems that finally talk to each other
Situation
Your accounting runs in one tool, your tax advisor works in another. In between sit exports, emails and follow-up questions. And no one has the numbers in real time.
How it runs
- 01Arasul reads the data from the tool where it already lives.
- 02A workflow reshapes it into the format the other system expects and hands it over.
- 03Recurring filings and the tax prep run largely on their own. You only approve.
- 04The key figures show up in a dashboard that sits right on your device.
What it gives you
What is pieced together by hand every quarter now happens on the side. Your KPIs live in one place, and no figure leaves your device.
Build what is missing
The Ara-Kit is open and free and works against any machine. Arasul on the device adds sign-in, releases and operation.
