Features
- Reads first, draws later——Loomi reads the full text first and extracts a fact sheet — question, ordered method steps, exact result numbers — before drawing anything.
- Zero text errors——Precise flowcharts and comparisons are drawn programmatically: spelling, units and arrow directions verified before delivery.
- Editable exports——High-res PNG plus vector PDF, with an editable .pptx on request — fix any label or arrow yourself.
- Styles for every use——Journal-clean, flat vector or 3D scientific illustration, with English, Chinese or bilingual labels.

- Pick type, style, labels Graphical abstract, method flowchart, mechanism, comparison or old-figure redraw — plus journal-clean, flat vector or 3D style, and English, Chinese or bilingual labels.

FAQ
- Is the free paper diagram generator usable?
- Yes — sign in to Loomi and generate your first figure free. Upload the paper, pick a diagram type, and keep refining styles, labels and exports in the same chat.
- Can one old figure be redrawn for publication?
- Yes. Upload the old figure or a hand sketch as the reference image and choose Old figure polish: content and labels stay identical, only the craft is upgraded to publication standard.
- Will the AI invent numbers in my results comparison?
- It should not. Precise figures are drawn with code so labels cannot drift, and every number is copied from your manuscript — never invented. Conceptual illustrations get a word-by-word check before delivery.
- Which diagram should a beginner start with?
- Beginners should start with a method flowchart: it has the clearest right answer and proves the accuracy pipeline. Then try a graphical abstract once you trust the wording.
- Do before-and-after examples show raw output?
- Treat polished examples as proof of style, not of zero editing. Ask for the source inputs and settings, then re-run with your own paper — check label accuracy, arrow logic and editability, not just the looks.
- Can I submit the figure to a journal?
- It can, with two conditions: every fact verified against your manuscript, and AI assistance disclosed per your target journal's authorship guide. You get high-res PNG, vector PDF and an editable .pptx for final tweaks.
