About Delimit

Where it came from

Delimit started as an internal tool. Back-office teams batching support tickets were doing the same thing dozens of times a day: copy a column of reference numbers out of a spreadsheet, turn it into one comma-separated line, paste that into a query or a filter box. Doing it by hand is slow and, more importantly, quietly error-prone — a value gets dropped, a stray space splits an ID in two, and nobody notices until the query returns the wrong batch.

The counters on the tool exist because of that. "Pasted" versus "In list" is not decoration; it is the check that tells you whether the thing you copied is the thing you actually got. The warning about lines over 1,900 characters exists because browser address bars truncate long URLs silently, and losing the tail of a filter list is the kind of bug that wastes an afternoon.

Once it was useful internally, there was no reason to keep it internal.

Why it runs in your browser

Every tool here is plain JavaScript that executes on your own device. There is no server that sees your text, because there is no server-side processing at all — the site is a folder of static files on a CDN.

That is a deliberate design constraint, not a limitation we have not got round to fixing. The lists people put into a tool like this are often internal: customer references, account numbers, ticket IDs, staff email addresses. Anyone pasting that into a random website should want to know it is not being uploaded. Keeping the processing local is the only version of that promise that is actually verifiable — open your browser's network tab and watch: nothing goes out.

It also means no account, no sign-up wall and no email capture. You should be able to use a utility in five seconds without negotiating for it.

How it stays free

Honestly: it costs very little to run. Static files on Cloudflare Pages, a domain, and no database. There is no venture funding to repay and no growth target to hit.

We would like it to eventually cover its own costs. If that happens it will be through something unobtrusive — a modest advertisement placed below the working area, never above it, or an optional way to support the project. What it will not be: a sign-up wall, a usage limit on the free tools, an interstitial before you can paste, or quietly selling anything about you. Those are the things that ruin utilities, and a utility that is annoying gets replaced within a week.

If advertising is ever added, the privacy policy will say so before it goes live.

What we're building next

The list converter is the first tool, not the whole plan. The same engine handles deduplication, sorting, case conversion and counting, so each of those becomes its own tool with its own page — see all tools for what exists today and what is coming.

Requests genuinely shape that order. If a tool would save you a repetitive job, tell us — a real description of the problem is worth more than a feature name.

Who makes it

Delimit is built and maintained by Mbule.Tech, a small independent software practice. The tools are written by hand, without a framework, which is why the whole site loads in well under a second on a phone.
