Core capabilities

Scientific content with a visual system

01

Redraw and edit figures

Rebuild supplied diagrams with improved hierarchy, accuracy, and visual consistency.

02

Create from text

Turn a precise biological description into a structured, publication-ready illustration.

03

Visual atlas

Use curated forms for DNA, RNA, proteins, complexes, regulatory elements, and other bio-objects.

04

English & Bulgarian

Produce clear scientific labels in English or Bulgarian with consistent typographic rules.

A focused workflow

Three steps to a finished figure

  1. 1

    Describe or upload

    Provide the entities, labels, relationships, panel order, or a source figure.

  2. 2

    Select a visual mode

    Use the visual atlas, detailed rendering, or ref mode when the source should provide facts only.

  3. 3

    Generate and refine

    Receive a coherent textbook figure and iterate on the scientific or visual details.

$book-figure redraw this figure, use ref mode, language=bg
$book-figure create  miRNA biogenesis—pri-miRNA → Drosha–DGCR8 → pore-exported pre-miRNA → Dicer → miRNA duplex → mature miRNA →  AGO-containing RISC → target mRNA degradation
