Write better LaTeX.
Right in Overleaf.
Corollary adds an AI sidebar to every Overleaf project. Improve prose, complete equations, find citations, and fix compile errors — by default using local models that never send your work anywhere.
Improve
Rewrites selected LaTeX for clarity, flow, and academic tone while preserving all commands and citations.
Complete
Continues writing from the cursor position, matching your document's existing style and structure.
Math
Explains equations in plain English, generates new LaTeX math, or fixes broken expressions.
Cite
Searches your local bibliography and Semantic Scholar. One click copies the BibTeX entry.
Errors
Detects compile errors in real time and provides step-by-step fixes for common LaTeX problems.
Local-First
Default mode runs fully on-device via Ollama. No API key required. No text leaves your machine.
How it works
Install the extension
Add Corollary from the Chrome Web Store and optionally pull a local model with ollama pull qwen3:8b.
Open any Overleaf project
The sidebar appears automatically. Select text or click a tab to get started — no configuration needed.
Get AI that knows LaTeX
Stream responses directly into the editor. The AI preserves your commands, citations, and document structure.
