Edit the text in any HTML page by clicking it
Paste your page HTML on the left. The right side renders it the way a browser does, with its own styles and fonts. Click a headline, a paragraph, or a button label and type. Your words change and the rest of your code does not.
Private by design. Everything runs in your browser. Your HTML is never sent to systeme.io, never stored, and never logged.
Six things worth knowing.
Most visual editors rebuild your whole document through the browser parser, which reformats code you never touched. This one edits the source string in place, so the only difference between what you paste and what you copy out is the words you retyped.
Only your words change Output
Paste a page, change nothing, copy it back: byte for byte identical
Each edit replaces one slice of the original source text. Indentation, quote style, attribute order, comments, and blank lines survive untouched, which matters when the file goes back into a builder or a repository.
Renders like the real page Preview
Your CSS, web fonts, and scripts all run
The preview is a real browsing context, not a sanitised approximation. Grid layouts, animations, hover states, and custom fonts behave the way they will once the page is live.
Text only, on purpose Scope
Words are editable, structure is locked
Clicking edits copy and nothing else. Elements cannot be moved, merged, or deleted, so a page cannot break while you are rewriting a headline. Structural work belongs in your page builder.
Honest viewport widths Layout
Fit renders at 1440 and scales down visually
A half width pane is narrow enough to trigger mobile media queries, which makes a healthy desktop layout look broken. Fit keeps the page at desktop width and shrinks the picture instead. The presets check the other breakpoints.
Relative paths resolve Assets
Site address field feeds the preview a starting point
Pages that point at images/hero.jpg have nothing to resolve against once the source leaves the server. Enter the domain the page lives on and images, stylesheets, and fonts load normally.
Interact mode for testing Modes
Editing off, page fully live
Switch to Interact and links, accordions, tabs, and scripts respond as usual, so you can reach a hidden state, then switch back to Edit text and rewrite the copy inside it.
Worth knowing before you start
Straight answers.
Paste the page source into the left pane. The right pane renders it as a real browser would. Click any headline, paragraph, list item, or button label and type over it. Every keystroke rewrites that one piece of text in the source on the left, which you can then copy back into your page. You never have to find the right line in the code yourself.
No. The output is rebuilt from your original source with only the edited text swapped in. Indentation, line breaks, quote style, attribute order, comments, and blank lines all stay exactly as you pasted them. If you paste a page and change nothing, what you copy out is byte for byte identical to what you put in. Most visual editors re-serialize the whole document through the browser parser, which quietly normalises formatting everywhere.
Because the page uses relative paths. A tag pointing at images/hero.jpg needs a domain to resolve against, and pasted source has none. Put the site address in the field above the preview and the images, stylesheets, and web fonts will load. Pages that use full addresses starting with https render correctly without it.
Text only, and that is deliberate. Editing words can never break a page. Moving elements, swapping image sources, or changing link addresses all change the structure, and structural edits in a visual editor are how pages get silently broken. Use this to rewrite copy, then edit structure in your page builder where you can see what you are changing.
A line break is a structural change, not a text change, so the editor blocks it. Pressing Enter inside an editable block would either split one element into two or insert a break tag, and neither can be written back without altering your markup. If you need a new paragraph, add the element in the source pane on the left, then edit its text in the preview.
Yes. Everything runs in your browser. Your HTML is never sent to systeme.io or any other server, never stored, and never logged. You can confirm it by opening your browser's developer tools and watching the network tab while you paste and edit.
Yes. Any HTML works: pages exported from systeme.io, ClickFunnels, Webflow, WordPress, Carrd, Leadpages, an email template, or a hand written file. The editor reads the source text itself rather than relying on any builder's structure, so a page from one tool behaves the same as a page from another.
In Edit text mode the copy is editable and links are held back, so clicking a button edits its label instead of navigating away. In Interact mode editing switches off and the page behaves exactly as it does live: links work, accordions open, scripts respond to clicks. Use Interact to check a state, then switch back to keep writing.
Skip the copy and paste. Edit on the page.
