Draft Builder Now Reads Your Drawings, Not Just Your Words

Ask an inventor to explain their invention and most will reach for a napkin before a paragraph. A sketch of how the parts fit together, an arrow showing which way something moves, a exploded view of an assembly — drawings are often the truest record of what was actually invented. Yet almost every drafting tool, AI-assisted or not, treats them as an afterthought: something to attach once the text is done, not something to draft from.

The gap between what you drew and what you wrote

This creates a real problem. Patent law requires a written description that discloses the invention in enough detail that someone skilled in the field could build it. It's common for a sketch to show a part, a connection, or a configuration that the inventor never got around to writing down — they explained it once, on paper, and assumed that was enough. When a draft is generated from text alone, that part of the disclosure simply doesn't exist. It has to be caught later, usually by a patent attorney flipping between the description and the figures, or worse, not caught at all.

What changed in Draft Builder

You can now attach up to five drawings — sketches, diagrams, or photos — directly to a draft. They don't just ride along as attachments. The AI actually looks at them, alongside your plain-language description and the interview answers you give, as part of the disclosure itself. If a drawing shows a part or connection your text never mentioned, the interview will ask about it directly: "In FIG. 1, what does the part between the sensor and the housing do?" That's a question a good patent professional would ask, and now the AI asks it too — because it can actually see what you drew.

Add a caption to each drawing explaining what it shows, and the AI reads that alongside the image itself, which helps it interpret rougher sketches correctly. When the draft is generated, it includes a proper "Brief Description of the Drawings" section, written in the standard form ("FIG. 1 is a …") and grounded only in what your drawings actually depict — no invented detail. Where a disclosed element is clearest in a figure, the description references it directly ("...as shown in FIG. 2"), which is exactly the kind of text-to-figure grounding that examiners look for.

• Up to 5 drawings per draft — sketches, diagrams, or photos (JPG, PNG, WEBP, or GIF, up to 3MB each)
• The AI reads drawings as disclosure, not decoration — visible parts count, and gaps between drawing and text get asked about
• Captions let you explain a rough sketch in your own words; the AI reads the caption and the image together
• Auto-generated "Brief Description of the Drawings" section, with FIG. references woven into the rest of the draft where relevant
• Informal drawings are fine for a first draft — formal patent drawings can come later, once your attorney is involved

Why this matters more than it sounds like it should

Text-only drafting tools are common; tools that treat your drawings as a real source of disclosure are not. That's the difference this update is aimed at: not a nicer upload widget, but an AI that looks at your invention the way you actually explained it — in words and in pictures — instead of asking you to translate everything into prose before it can help. For a mechanical assembly, a UI flow, or a circuit layout, that's often the difference between a first draft that needs a full rewrite and one that's genuinely ready to hand to your attorney with the drawings already accounted for.

As always: a Draft Builder output is a structured first draft, not legal advice, and drawings uploaded here are informal — a research and drafting aid to save you and your attorney time, not a replacement for formal patent drawings or professional review before filing.
