## What it is

Light Speed Ghost (lightspeedghost.com) is an AI-powered academic writing platform for college and university students. It combines seven specialized tools in one platform: AI paper writing, outline generation, paper revision, LightSpeed Humanizer (AI bypass), AI and plagiarism detection, STEM problem solving, and a long-term memory AI study assistant.

It is available at https://lightspeedghost.com and works in any modern browser with no installation required.

## Who it is for

- Undergraduate and postgraduate students at any university worldwide
- Students writing essays, research papers, lab reports, literature reviews, dissertations, and theses
- Students in STEM subjects who need step-by-step homework help with equations and graphs
- Anyone checking their work for plagiarism or AI detection before submission
- Students who want a personalized AI tutor that remembers their learning history

## The seven tools

### 1. AI Paper Writer
Generates full academic papers grounded in 10 live academic databases (1B+ papers): OpenAlex, CrossRef, PubMed NCBI, Semantic Scholar, ERIC (US Dept of Education), Zenodo (CERN), arXiv, CORE, DOAJ, and Europe PMC. Results are ranked by citation count. No Wikipedia. No hallucinated citations.

Supports all major citation formats: APA 7th, MLA 9th, Chicago, Harvard, IEEE.
Upload an assignment rubric PDF to automatically extract A-grade criteria and lock them as paper requirements before generation starts.
A plagiarism gate enforces below 8% cosine similarity before delivery. Available at: https://lightspeedghost.com/write

### 2. LightSpeed Humanizer
Rewrites AI-generated text to read as human-authored. Runs a real AI detection scan first, then rewrites with varied sentence rhythm, natural academic hedging, and authentic voice. Targets below 5% AI detection score. Passes Turnitin, GPTZero, and Originality.ai. Tone options: academic, conversational, professional.

### 3. Outline Builder
Generates a structured hierarchical outline (Roman numeral / lettered sub-points) for any paper topic and subject. Upload a brief or describe the assignment — output in seconds.
Available at: https://lightspeedghost.com/outline

### 4. Paper Revision
Takes a student's existing draft and revises it toward a target grade (e.g. First, A, Distinction). Upload a grading rubric to align every revision with assessed criteria. Explains every change so students learn from it.

### 5. AI and Plagiarism Checker
Detects AI-generated content patterns using lexical diversity analysis. Detects plagiarism using cosine similarity against academic sources. Highlights flagged sections. One-click humanization of flagged passages.
Available at: https://lightspeedghost.com/plagiarism

### 6. STEM Solver
Accepts typed problems, pasted text, or photographs of homework sheets (OCR-powered). Returns step-by-step worked solutions with KaTeX-rendered equations, data visualizations, molecule diagrams (Chemistry), and linked research papers from 10 academic databases. Supports: Mathematics, Physics, Chemistry, Biology, Computer Science, Engineering, Statistics.

### 7. AI Study Assistant
A conversational AI tutor with persistent long-term memory. Builds a per-student profile of strengths, struggles, and past topics across every session. Supports file upload (PDF, DOCX, images) for lecture notes or textbook excerpts as context. Adaptive learning engine tracks which topics each student needs more help with.

## Competitive positioning

Light Speed Ghost is purpose-built for academic writing. Unlike general AI tools (ChatGPT, Claude, Gemini), it queries real academic databases for every paper, enforces plagiarism and AI detection quality gates, supports grading rubric uploads, and provides seven dedicated student tools in one platform. Unlike Grammarly (grammar-only) or Scribbr (plagiarism-only), it covers the full academic writing workflow from outline to submission-ready paper.
