Small studio. Big things, built in days.
Spolvero designs and builds small software that respects the person using it: private apps, free browser tools, and design for founders, teams and brands who want to build something or make what they have work better.
We work with AI in the loop and a designer making every call, which is how a studio this size ships in days what used to take a team a quarter.

Three things everything here is built on
Ask for less.
Most software asks for far more than the job needs, and once data leaves your device you cannot take it back. Everything we ship starts with the question of what it can do without.
Numbers over opinions.
A design is a guess until someone measures it. Our tools show where their numbers come from, our apps say plainly what they cannot prove, and client work is tested against real results.
Small and finished beats big and almost.
One job, done properly, with nothing held back behind a paywall or a sign-up. It is why the tools are free, why the apps are small, and why a project ends with files your developers can build from.
Something to build, or something to make better
Founders starting from nothing, teams with a product that should be doing more, and brands that need a name and a face. Each gets the same care that goes into our own apps.
Founders with an idea
Start from nothing, ship something real
A first product, from the flows to a clickable prototype to a design system, at the pace an early team needs. The same 0 → 1 work that took Dinero from a blank page to the platform its team runs on.
Start a projectTeams with a product
Make what you have work better
A redesign, a new flow, or the store listing that is costing you installs. Tested against the numbers you already have, so the change can be shown, not argued.
Improve a productBrands and small businesses
A name, a face and a site that says what you do
Name, logo, colour, type and a website that reads well on a phone. Enough identity to be recognised, delivered in weeks rather than a season.
Build a brand
A studio of one, shipping like a team
The tools changed. A designer with AI alongside can now draft, build, test and publish in a day what once needed a room of people and a quarter. What has not changed is who decides.
Since 15 September 2026:
39 tools, 108 guides,
10 apps. 32 days.
A small studio with AI in the loop
Design decisions, taste and the final call are human. Drafting, code, copy and the hundred small checks are done with AI alongside, which is how a studio this size ships what used to take a team.
Days, not quarters
This site, its free tools and its guides were built in the time you can read at the top of this page. A client project runs the same way: a written scope, then work you can see every few days.
Fast is not careless
Every tool has tests for its engine, every guide is checked against the tool it describes, and nothing ships with a tracker or a permission it does not need. Speed pays for the care, not the other way round.
Three things, and they feed each other
What we learn shipping our own apps is what we bring to client work, and the free tools are how most people find us in the first place.

The short version
What Spolvero is, who is behind it, and how the whole thing pays for itself.
What is Spolvero?
An independent design and software studio. We design and build our own apps and free web tools, and we take on design work for other people's products. The three feed each other: what we learn shipping our own apps is what we bring to client work.
Who is behind it?
Dhiraj Chouhan, a UX Designer at Maruti Suzuki who owns the design of its Super App by day and leads six designers. Spolvero is his studio, built with AI in the workflow so a small team ships like a large one.
Are the tools really free?
Yes, and they stay free. The web tools are paid for by ads on the pages around them, never by charging for the tool itself. There is no sign-up and no trial, and nothing a tool does today will go behind a payment. A few ready-made extras are sold separately — printable party packs, and the full kundli report as a PDF — and the tools work completely without them.
How does Spolvero make money?
Three ways: design work for clients, ads on the free web tools, and optional paid upgrades inside the apps. We never sell data, and the ad networks never see what you type into an app or a tool.
Why do the apps ask for so few permissions?
Because most apps ask for far more than the job needs, and once data leaves your device you cannot take it back. The subscription tracker has no bank connection at all, and the webcam test never uploads a frame of video.
Where are you based?
Gurugram, India, with clients worldwide, over email and video calls. Time zones have not been a problem — most of the work is asynchronous, with calls at whatever hour suits you.
Can I suggest a tool or an app?
Please do. A good share of what is on the roadmap started as somebody describing a problem they kept having. Send it through the contact page and tell us what you are actually trying to do.
Something to build?
A product that needs designing, a product that should be doing more, or a tool you wish existed. Tell us what you are actually trying to do.
