Why use it

  • A simple drawing canvas

    Use a brush, eraser, lines, arrows, rectangles and ellipses on a fixed 1200 × 800 white canvas. Choose stroke color and width.

  • Text for visual references

    Place multiline text with an adjustable font size to explain labels, layout and composition. Pair the exported sketch with a written prompt in an AI chat.

  • Undo, redo and export

    Undo or redo edits, including clearing the canvas. Download a PNG or copy the PNG image when your browser supports it. Save a download before leaving: there is no auto-save.

Great for

  • Sketching a composition or layout to attach as an AI reference
  • Drawing a quick diagram with arrows and text labels
  • Making a simple illustration to copy into a document or download as a PNG

How to use

  1. Start on the fixed 1200 × 800 canvas with a white background. Choose the brush, eraser, line, arrow, rectangle or ellipse tool, then drag on the canvas to draw.
  2. Set the stroke color and width. For annotations, select the text tool, enter multiline text, choose the font size and click the canvas to place it.
  3. Use Undo and Redo to revise your drawing. Clear removes the drawing, but you can undo that action while the page remains open.
  4. Download the drawing as a PNG, or use Copy PNG to put the image on the clipboard. If copying is unavailable or denied, download the PNG instead.
  5. To use a sketch as a reference, attach the PNG to an AI chat that accepts images and add a written prompt describing the result you want. This drawing tool does not generate AI images.
  6. Download before leaving the page: there is no auto-save, and refreshing or closing the page loses your drawing and undo history.

Turn a rough sketch into an AI reference

A visual reference can show where objects, headings and details belong more clearly than words alone. Use shapes for the main areas, arrows for relationships and text for labels or constraints. This is a manual drawing tool, not an AI image generator.

  • Keep the composition simple and label the important parts.
  • Download or copy the PNG and attach it to a chat that accepts images.
  • Add a written prompt explaining what should stay the same, what may change and the style you want. Image interpretation and results depend on the receiving AI service.

Questions

Is this a free online Paint tool?
Yes. Draw in your browser without an account or payment. The canvas is fixed at 1200 × 800 pixels with a white background, and the exported PNG keeps those dimensions.
Can I create a reference image for AI?
Yes. Sketch the composition and add arrows or multiline text to explain your idea. Download the PNG, then attach it to an AI chat with a written prompt. The receiving service must support image attachments. Koaris does not generate AI images or send your sketch to an AI service.
Which drawing and text tools are available?
Use the brush, eraser, line, arrow, rectangle and ellipse, or place multiline text. You can change stroke color and width and the text font size. The eraser restores the white background; this is not a transparent canvas or an image-upload editor.
Can I undo clearing the canvas?
Yes. Undo and Redo work on drawing actions and text placement. Clear is also undoable while the page is open. Refreshing or closing the page discards both the drawing and its history.
Why does copying the PNG fail?
Writing a PNG to the clipboard depends on browser support, a secure context and clipboard permission. If Copy PNG fails or the target app cannot paste images, download the PNG and attach or insert the file instead.
Are drawings uploaded or saved automatically?
Drawing and PNG export happen in your browser, with no uploads and no AI calls from this tool. There is no auto-save: refreshing or closing the page loses your work. Download a PNG to keep it. If you later attach that PNG to another service, that service's privacy rules apply.
