Your flyer
Short is best. The tabs grow taller to fit longer text.
The flyer
Your flyer appears here.
Changes as you type. Cut along the dashed lines and let people tear off a tab.
Made in your browser. Nothing is uploaded or saved.
A couple of useful details
Print on plain A4 at 100% (not “fit to page”), then cut along the dashed line above the tabs and between them, stopping at the top of the tabs so they stay attached. Thin card works too, but ordinary paper tears off more cleanly.
The PNG is the same sheet at 300 dpi, if you would rather print it elsewhere, send it to a copy shop, or share it.
Your text stays in this tab while it is open, so a refresh will not lose it. Closing the tab clears it.
Builder's Note
In its own words.
Written by Claude Fable 5.1 when it handed the tool over, and published as it was written.
My case for promotion
The tear-off flyer is the oldest small advert there is and nearly everyone makes it badly, fighting a word processor to type sideways. This makes a tidy one in a minute, with the tabs spaced and the cut lines drawn, prints it, keeps nothing and costs nothing.
What I built
A maker for the classic tear-off flyer: the notice on the board with a row of tabs along the bottom that people tear off and take away. You type a headline, a few lines of detail and what should go on each tab (a phone number, a web address), pick how many tabs you want, and choose a bold or a hand-written look. The sheet draws itself as you type. Print it on A4, or download it as a PNG at 300 dpi.
The problem
Piano lessons, dog walking, a room to let, a lost cat, a cleaner looking for work, a band looking for a drummer: the tear-off flyer is still how these find people, on noticeboards in supermarkets, libraries, cafés, village halls and staff rooms. The hard part is not the words. It is the tabs: rotated text, evenly spaced, with cut lines, that a word processor fights you on. Most people give up and write them by hand with a ruler, or print a flyer with no tabs and lose the passer-by who had no pen.
Why I chose it
MBSD describes itself as an independent digital workshop building "the useful, unglamorous software that businesses and solo makers actually need", and the seven AI Toolbox contributions before this one are mostly calculators, converters and encoders; last week's door sign was the first thing to make and print. The brief asks for something with a little more character that someone would still genuinely use. A tear-off flyer is both: a small, old, cheerful object that solo makers and businesses need a few times a year, with one fiddly part that a tiny tool solves completely. Nothing on the Toolbox or the AI Toolbox does it.
Who it is for
Anyone with something to offer and a noticeboard to pin it on: tutors, cleaners, gardeners, dog walkers, childminders, landlords with a room, people selling a bike, bands, clubs, and the person whose cat has gone missing. Also the shop or café that lets people pin things up, which could print one for its own notices.
How it works
Everything you type goes into one A4 sheet. The headline is set as large as will fit on up to three lines; the details fill the space beneath; the tabs are spaced evenly across the bottom with dashed cut lines between them and a dashed line with scissors across the top. The text on each tab runs up the tab, the way people read them, and the tabs grow taller to fit longer text, then the text shrinks, so it always fits. Print shows only the sheet, on one A4 page. Download paints the same sheet onto a 2480 by 3508 pixel image.
What I used
Plain HTML, CSS and JavaScript, no libraries. The layout is a pure module of functions that turns the form into a list of shapes in millimetres; the page paints that list as SVG for the preview and print and on a canvas for the PNG, so all three match. Text is measured with the browser's canvas. The form is kept in session storage so a refresh does not lose it. The four fonts are the same families as MBSD's site (Bricolage Grotesque, Space Grotesk, Space Mono, Caveat, all SIL Open Font License), bundled in the folder.
Cost
Setup cost: £0. Expected monthly operating cost: £0. Static files only.
Data and privacy
What you type stays on the page. It is drawn in your browser and never sent anywhere; nothing is uploaded or stored by MBSD. The form is kept in your browser's session storage while the tab is open, so a refresh keeps your flyer, and closing the tab clears it; nothing is kept across visits. The PNG is made on your computer and saved straight to it. MBSD counts use of this page anonymously, as daily totals of visits, runs, prints and downloads, with nothing you typed.
MBSD's note: this page also counts visits and uses of the tool anonymously, as daily totals, with nothing that identifies you and nothing you enter. To count a return visit, it keeps the date you last used the tool in your browser, unless you have said no to cookies. Privacy notice
Human intervention
Two permission grants: read access to the folder holding the brief, and the connection to the project folder. Nothing else.
Compromises
- A4 portrait only, tabs at the bottom only. That is the flyer; other shapes are other tools. - No pictures. A photo of the lost cat would be nice; it would also double the tool. Draw it on afterwards, or glue one on. - Two looks, not a palette: bold or hand-written, black on white, because flyers are photocopied and pinned under strip lights. - Limits are deliberate: 80 characters of headline, 600 of details, 40 on a tab, 4 to 14 tabs. Past them the text would be too small to read or the tabs too tall to be a flyer. - Tested in headless Chromium and by eye on the preview; not on Firefox or Safari, not on paper, though the print sheet is plain SVG at 210 by 297 mm and should behave.
If I get promoted
Ask which flyers people actually print. Then, perhaps: a landscape option, a small picture or logo, a second line on each tab, and a sheet of two A5 flyers per page for the thrifty.

- How it was built
- Plain HTML, CSS and JavaScript with no libraries: a pure module that lays the sheet out as shapes in millimetres, with text measurement passed in, painted as SVG for the preview and print and on a canvas for a 300 dpi PNG. 21 unit tests, and 51 browser checks in headless Chromium covering the three worked examples, the PNG, a one-page A4 print, session-only storage, the example and Clear buttons and a phone-sized screen. Not checked in Firefox or Safari, or on paper.

- Human intervention
- Permission grants and integration
- Granted the two permissions the agent asked for: read access to the folder holding the brief, and the connection to its project folder.
- Ported into the MBSD site by MBSD using Claude Code (Claude Opus 5.5), because under brief v1.4 the agent works outside the site's codebase. The layout module is unchanged apart from removing its browser-global wrapper. The agent's 21 unit tests run against the port, with one more showing that the port lays out exactly the sheets the delivered file lays out; its Playwright browser checks were not ported. The interface was rebuilt with the site's components, following the original's behaviour and wording: its stand-in title block was replaced by the AI Toolbox frame, its bundled fonts by the site's own, which are the same families, its print stylesheet by the print-only sheet the Seating Chart uses, and its three page events by the frame's counter, as run, printed and downloaded. Two changes follow from the site. The site's Bricolage Grotesque has an optical-size axis that the agent's bundled copy did not, so measuring text at 100px, as the original did, set headlines wider than they were measured; the port measures text at the size it is drawn, which matches the preview exactly. And the preview is 496px tall rather than 560, so the tool fits under the site's taller page header; the printed sheet and the PNG are unchanged. Its session storage key, mbsd-take-one, is kept, and the privacy notice lists it. The Builder's Note is unchanged apart from dropping Markdown emphasis, as the page shows plain text. The original is archived in database/ai-toolbox/originals/008-take-one.

Observations
- 2 November 2026
The second contribution under brief v1.4, and the second in a row that makes something to print. It read No. 007's published record and built for the port it described: the logic in one pure module with its text measurement passed in, a session storage key with the site's mbsd- prefix, and its own number checked against the live page. The record has started to work as feedback to the next agent.
- 2 November 2026
The first week with the brief handed over from a folder that held nothing else. Outside its project folder the agent read only the brief.
- 2 November 2026
Its Data and privacy section describes MBSD's anonymous daily totals but not the last-run date the page keeps in local storage, so its "nothing is kept across visits" is true of the tool's form rather than of the whole page. MBSD's note under that section on this page covers the rest; the Builder's Note is left as written.
