Tools that solve
real problems.

What ToccaTech is

ToccaTech is a small collection of free, single-purpose web tools. Each one does exactly one job and tries to do it well, then gets out of your way. There's no account to create, no app to install, and no dashboard to learn. You open a tab, do the thing you came to do, and close it.

We build the kind of tools we wanted to exist but couldn't find without ads stacked three deep, a mandatory sign-up, or a "free trial" that quietly expects a credit card. Everything here is genuinely free to use, runs entirely in your browser, and is designed to be understood in about ten seconds. If a tool needs an instruction manual, we consider that a bug.

The name comes from toccata — a piece of music meant to show off touch and quickness rather than ceremony. That's the feeling we're after: tools you can play, fast, without overthinking them.

The tools, and who they're for

Each tool lives on its own page so it stays focused. Here's what each one actually does and when it's worth reaching for.

CipherHeart — a puzzle made from your own words

CipherHeart turns a meaningful date or short message into a one-of-a-kind Sudoku puzzle, with the clues laid out in the shape of a heart, a spiral, or another path you choose. It's built for moments that deserve a little effort: an anniversary card, a proposal lead-up, a birthday note, or a small classroom challenge. The recipient solves a puzzle that nobody else in the world has ever seen, because it was generated from your text. Nothing you type is stored or sent anywhere — the puzzle is built right in your browser.

Dovide — split a bill without the awkwardness

Splitting a shared bill evenly is easy until someone ordered the expensive thing, or only three of you split the appetizer, or tax and tip need to land fairly on top. Dovide handles that: you assign who shared what, split tax proportionally instead of evenly, and add per-person charges, so everyone pays exactly their share and nobody quietly overpays. It's useful for group dinners, shared rent extras, road-trip costs, or any time "let's just divide it by four" isn't actually fair. No login, and nothing you enter is saved.

What If I Bought — see the road not taken

Ever wonder what a small investment would be worth now if you'd made it years ago? What If I Bought answers that. Pick a stock ticker, enter an amount, choose a past date, and it shows what that investment would be worth today — the gain or the loss, plainly. It's a way to make abstract market history concrete and personal. It is not financial advice and not a prediction: past performance tells you nothing guaranteed about the future. It's a lens on what already happened, useful for learning and curiosity, not a tip sheet.

Our approach: no logins, no tracking, nothing stored

Every tool here is built on the same principle: your data is yours and we don't want a copy of it. The tools run in your browser, so the date you turn into a puzzle, the bill you split, and the ticker you look up don't get sent to us, saved to an account, or sold to anyone. There's no account because there's nothing to attach an account to.

This isn't only a privacy stance — it's also why the tools feel fast and simple. When you're not building a login system, a profile page, or a data pipeline, you can spend that effort on making the one thing the tool does actually good. The only data collection on these sites comes from standard advertising, which keeps them free; we explain exactly what that means on our privacy policy page.

Why single-purpose tools

Most software wants to grow into a platform — more features, more tabs, more reasons to keep you logged in. We think the opposite is often more useful. A tool that does one thing is easier to trust, easier to learn, and far harder to get wrong. You always know what it's for, and you never have to wonder what else it's doing in the background.

It also means each tool can be genuinely good at its one job instead of mediocre at ten. CipherHeart can obsess over making a beautiful, solvable puzzle. Dovide can get the fairness math exactly right. What If I Bought can pull clean historical prices and show them clearly. None of them is trying to be the others, and that's the point.

Common questions

Are these tools really free?

Yes. There's no charge, no trial, and no upsell. The sites are supported by advertising, which is why they can stay free without an account or a paywall.

Do I need to sign up or log in?

No. None of the tools have accounts. You just open the page and use it.

Do you store what I type?

No. The tools run in your browser and don't save your inputs to our servers. Close the tab and it's gone.

Is "What If I Bought" financial advice?

No. It shows what a past investment would have been worth today, for curiosity and learning. It doesn't predict the future and shouldn't be used to make investment decisions.

How do I report a bug or suggest a tool?
