# ConceptViz - Full Documentation for LLMs

> AI scientific diagram & figure generator for researchers, educators, and students

## Overview

ConceptViz is a web application that transforms plain-text descriptions of scientific concepts into professional diagrams and figures. It serves the full academic range — publication-ready research figures for journals and theses, accurate medical illustrations, and classroom teaching visuals for K-12 through university. Users describe what they want to visualize; the AI generates high-quality, editable images in seconds. Pricing is pay-as-you-go credits with no subscription.

## Problem We Solve

Creating scientific visuals is slow and skill-intensive. Existing options fall short:
- Stock images are generic, often inaccurate, and carry copyright restrictions
- Design tools require significant time and training
- Hiring an illustrator is expensive and slow for a single thesis figure or lecture slide
- Generic AI image tools lack scientific accuracy and editability

ConceptViz generates custom, level-appropriate, publication-quality scientific figures on demand.

## How ConceptViz Compares

Compared with subscription-based scientific illustration platforms and manual icon-assembly editors:

- **Pricing model**: pure pay-as-you-go credits starting at a $5 one-time pack, instead of $30+/month subscriptions. Ideal for occasional needs like a thesis figure or a single journal submission; credits from packs never expire
- **Workflow**: text-to-figure AI generation — describe the figure in plain language and get a complete, editable result in seconds. No template library to browse, no drag-and-drop editor to learn
- **Free trial depth**: new accounts get enough credits to generate 2 images on CV-2 (the highest-fidelity model), so users can judge real output quality before paying anything
- **Breadth**: 180+ purpose-built generators, one per figure type (graphical abstracts, PRISMA diagrams, medical illustration, syntax trees, genograms, …), each free to try without an account
- **Education**: deterministic math/teaching diagram tools are free forever and never consume credits

## Core Features

### AI Diagram Generation
- Natural-language input, optimized automatically for scientific/educational context
- Two model tiers: **CV-1** (fast, everyday diagrams) and **CV-2** (high-fidelity scientific accuracy, balanced/max depth)
- Multiple variants per generation; 1K/2K/4K output; multiple aspect ratios
- Image editing after generation, including in-image text correction (Edit Text)

### Studio Workspace (`/studio`)
- Main authenticated workspace: prompt composer with reference image attachments
- Reusable assets: saved styles, rules, and prompt templates, referenced inline with "@"
- Voice input for dictating prompts
- Generation history with per-image download and editing

### Free Online Generators (`/tools`, 180+ pages)
- Purpose-built generators for specific figure types, free to try without an account
- Research-oriented: graphical abstract maker, medical illustration generator, conceptual framework generator, PRISMA flow diagram generator, scientific poster generator, syntactic tree generator, genogram maker, chemistry structure generator, and more
- Deterministic teaching tools (exact SVG rendering, always free, no credits): number lines, fraction strips, ten frames, base-ten blocks, tally charts, and other math teaching aids

### Subject Coverage
- **Physics**: forces, motion, energy, waves, electricity, magnetism, optics, experimental setups
- **Chemistry**: atomic structure, bonding, reactions, organic mechanisms, lab apparatus
- **Biology**: cells, anatomy, ecosystems, genetics, molecular biology, signal transduction
- **Medicine**: anatomy, physiology, pathology, clinical and surgical illustration
- **Math**: geometry, graphs, statistics, teaching manipulatives
- **Earth Science**: geology, weather, astronomy, climate
- **Computer Science**: algorithms, data structures, networks, UML
- **Data Science**: statistical plots, ROC curves, data visualization

## Pricing Structure (pure credit model — no subscriptions)

### Free
- 2 credits granted on signup (7-day validity) — enough for 2 images on CV-2, the highest-fidelity model
- Deterministic teaching tools are always free and never consume credits

### Credit Packs (one-time purchases)
- **Starter**: $5 — 10 credits
- **Basic**: $10 — 22 credits
- **Plus**: $30 — 72 credits (most popular)
- **Power**: $80 — 220 credits
- **Max**: $200 — 620 credits

### Credit Costs per Image
- CV-1 / CV-2 Standard: 1 credit (1K/2K), 2 credits (4K)
- CV-2 Max depth: 2 credits (1K/2K), 4 credits (4K)

### Auto-Refill (optional)
- Opt in during checkout or in Settings → Credits
- Automatically re-purchases your chosen pack when the balance drops below a threshold
- Every automatic top-up grants +20% bonus credits
- Monthly spending cap and one-click off switch included
