How to evaluate a vector illustration in 'Draw Idea'
The 'Draw Idea' tool creates original scalable vector illustrations from text description. Unlike photorealistic generators, you get SVG or PNG with clean lines and shapes. But how do you know the result is really good? This guide breaks down evaluation criteria on a specific example and shows how to check accuracy, completeness and suitability for your tasks.
Open tool: AI vector illustration ↗What the tool actually creates
'Draw Idea' transforms your text into a vector composition. This is not a photograph and not a realistic image, but a set of geometric shapes, lines and fills that can be scaled without loss of quality. You enter a scene description, optionally specify style and output format, then click 'Generate' and get one result in a separate panel.
Important to understand limitations: the tool does not create photorealistic images, does not generate audio or video, does not support batch processing and does not automatically save results. Only SVG and PNG formats are available. Input is limited to 8000 characters for the first field and 1000 for details. This means quality assessment must consider the vector nature of the result.
Example prompt: 'Small orange robot waters a plant under a half moon'. Style: 'minimalism, flat colors'. Format: SVG.
Criterion 1: accuracy of description matching
The first step of evaluation is to check whether all key elements from your text are present in the illustration. If you specified a robot, a plant and a half moon, they should be recognizable. Pay attention to color: the orange robot must be exactly orange, not red or yellow. The half moon must have a characteristic shape, not just a circle.
Accuracy also includes the relative positioning of objects. Robot waters a plant - means there should be visual contact between them: a watering can, a water stream or a tilt. If the robot stands to the side and the plant in another corner, this reduces accuracy. Check if any extra details have been added that you did not request - they may be distracting.
To check you can mentally break the description into meaning blocks: subject (robot), action (waters), object (plant), background (half moon). Then sequentially find each block in the illustration. If any block is missing or distorted, accuracy is insufficient.
In the illustration the robot is depicted with a watering can, from which water flows onto the plant. The half moon is visible in the top corner. All elements are in place - high accuracy.
Criterion 2: completeness and detailing
Completeness means the illustration does not look empty or unfinished. Vector graphics often uses minimalism, but even in it there should be necessary details. For example, the robot may have an antenna, eyes, hands; the plant - leaves and stem; the half moon - a clear contour. If the robot is just a rectangle with legs, it may be acceptable for a schematic style, but if you requested detailing, evaluate its presence.
Also check for 'holes' in the composition: empty areas that disrupt the balance. A good vector illustration fills space harmoniously, even if the background is white. Pay attention to scale: the robot should not be tiny on a huge sheet, and the plant should not overwhelm the robot if they are meant to be equal.
Completeness is related to your original request. If you specified 'minimalism' style, do not expect photorealistic shadows and textures. But even in minimalism there should be clear shapes and readable silhouette.
In the robot example: if the robot has only a head and torso but no hands, and the watering can floats in the air, this reduces completeness. Adding simple hands and a water stream improves the result.
Criterion 3: suitability for use
Suitability is the practical value of the illustration for your task. Ask yourself: can I use this SVG or PNG in a presentation, on a website, in a document? Vector format allows scaling without quality loss, so check how the image looks when enlarged. Lines should remain sharp, colors should not blur.
If you plan to edit the illustration, SVG should have separate layers or groups. In the 'Draw Idea' tool you get a ready-made file, but you cannot control layers through the interface. However SVG by nature is editable in graphic editors. Check if objects have not merged into one path - this will complicate editing.
Also evaluate the color palette: does it suit your brand or theme? If not, you can change colors in an editor. Suitability also depends on license - the tool does not explicitly state, but it is assumed you can use the result at your discretion. Make sure there are no watermarks or artifacts.

How to check the result: step-by-step algorithm
Step 1: Compare the illustration with the original text. Write down all nouns and adjectives from the prompt and mark what is depicted. Step 2: Evaluate composition - are there no gaps, do not objects overlap undesirably. Step 3: Check technical parameters: format (SVG or PNG), file size, no errors when opening.
Step 4: If possible, open SVG in an editor (e.g. Inkscape) and see how objects are grouped. This shows how easy it is to make edits. Step 5: Evaluate whether the style matches the requested one. If you requested 'minimalism' but got a clutter of details, that is a mismatch.
Step 6: Check for artifacts: clipped lines, overlays, strange color transitions. In vector graphics such errors are immediately noticeable. If everything is clean, the result can be considered high quality.
For the robot example: open SVG in Inkscape, see that robot, plant and half moon are separate groups. Colors are set by fill. This is convenient for editing.
Tool limitations and typical errors
The tool does not guarantee ideal fit in complex scenes with many objects. If you describe ten characters and a background, the result may be simplified or distorted. The model may make errors, and queue and availability vary. Do not expect photorealism: this is a vector composition, not a render.
Another limitation - absence of batch processing and automatic saving. You get one result at a time. If you need several options, you have to generate repeatedly. Also there are no integrations and possibility of direct publishing. Input is limited in length, so too long a description may be truncated.
Typical error - asking for a photorealistic image. The tool does not do that. Another error - expecting audio to be sent to AI: speech is processed locally via eSpeak, but this does not relate to vector graphics. In the context of illustrations remember: you get only SVG or PNG.
If you request 'robot in hyperrealism style', the result will still be vector and simplified. Better to immediately indicate 'flat vector' or 'minimalism'.
Evaluating vector illustration quality in 'Draw Idea' boils down to three criteria: accuracy (are all elements from the request present), completeness (are there no gaps or extra details) and suitability (can the file be used in your work). Check the result step by step, comparing with the original text, and consider the tool's limitations. Remember this is vector graphics, not photorealism. Following this guide you can quickly pick successful illustrations and efficiently use them in your projects.
