JoinLines is eight browser-only tools that each do one thing well. Your text never leaves your tab — verifiable in DevTools → Network. No accounts. Built and maintained on weekends.
JoinLines started the way these things usually do: needing to alphabetize a list, opening one of the dozen ad-cluttered text-tool sites, and closing the tab in disgust.
Eight days later there were eight tools. No accounts, no upload — the whole site is a few kilobytes of JavaScript and an Intl.Collator call. It loads instantly on a phone over 3G.
We update it on weekends. There's no roadmap meeting, no growth team, no shareholders. If you find a bug or want a feature, the email in the footer goes to a real human.
Every tool runs in your browser. When you paste text into JoinLines, JavaScript on the page does the work — sorting, counting, splitting, comparing. The text is never sent to our server. Verify it yourself: open DevTools, switch to the Network tab, run any tool, and you'll see zero requests carrying your input.
Today there are no analytics scripts and no ads on this site. If we ever add either, the rules will be: page-view counts only (anonymous, IP anonymized, never tied to what you paste), and contextual ads only (picked from page content and country, not from a profile of you). The two streams would never combine.
We'll update this page and the Privacy page the same day either is enabled, naming the specific provider. Until then, the only network requests this site makes are for static assets and Google Fonts — check DevTools to confirm.
Every tool does one transformation, well. We refuse the urge to add a "swiss army knife" mode. If your task needs two transformations, do them one after the other.
Everything is JavaScript that runs on your machine. Your text never leaves the page. We can't see what you paste — and we like it that way.
No sign-up, no email gate, no "save your history". The friction of a bookmark is the friction we want — and nothing more.
The whole homepage is under 100 kilobytes. We watch the bundle size like a hawk. A tool you can't open on a phone in a hurry isn't a tool, it's a brochure.
No login, no email, no syncing. The friction is the feature.
The website works on mobile. An app would mean shipping the same code twice.
Sorting a list does not need an LLM. We will not add one for retention.
No paywall, no premium mode, no "unlock for $5". The eight tools on this site stay free, forever. If a paid API for high-volume users ever shows up, it lives on a separate domain — the website here does not change.
No mailing list. Bookmark the page if you want to come back.
No "Are you sure you want to leave?" No surprise email collection. No fake urgency timers.
No ads run on this site today. If we ever add them, they'll be contextual — based on the page you're reading, not on a profile of you. We won't sell or share your activity for retargeting.
