Frequently Asked Questions
What is an ASCII wireframe?
A diagram or UI mockup drawn entirely with text characters, which stays readable in any editor and any terminal.
Do I have to place characters by hand?
No. The visual canvas has drag-and-drop tools, then exports the result as clean text.
Can I paste it into Markdown?
Yes. Export as a Markdown code block and the diagram keeps its alignment in docs, READMEs and issues.
Why use ASCII instead of an image?
Plain text diffs cleanly, loads anywhere and works well inside AI prompts and code comments where images cannot go.
Is the ASCII wireframe generator free to use?
Yes, the generator is completely free with no account, subscription, or watermark. Open the editor in any modern browser, start drawing immediately, and export as many diagrams as you want. There are no export limits or hidden paid tiers.
Which characters are used to draw the lines and boxes?
The editor uses Unicode box-drawing characters such as ┌, ─, │, and └, plus arrow connectors like ─▶ and ◀─. These align perfectly in monospace fonts, so your diagram keeps its shape in code editors, terminals, GitHub READMEs, and Markdown files.
Can I move or resize shapes after drawing them?
Yes, everything stays editable. Drag any box to a new position, resize it from its edges, or retype its label, and the generator redraws the connecting ASCII lines and corners automatically so borders never come out broken or misaligned.
Are my diagrams uploaded to a server or saved anywhere?
No, all rendering happens locally in your browser. Your wireframes are not uploaded to any server, which keeps confidential architecture or product sketches private. Save your work by copying the text or downloading the exported file to your device.
