Make sure the extension is enabled in chrome://extensions and that you are on a project page (overleaf.com/project/…). The sidebar does not load on the Overleaf dashboard or editor splash pages.

If it still doesn't appear, reload the page with the extension active. If the problem persists, check the browser console for errors and send them to us.

Ollama rejects requests from browser extension origins by default. You need to set OLLAMA_ORIGINS once:

macOS (desktop app): run launchctl setenv OLLAMA_ORIGINS '*' in Terminal, then fully quit Ollama from the menu bar and relaunch it.

macOS / Linux (terminal): start Ollama with OLLAMA_ORIGINS='*' ollama serve.

Windows: set OLLAMA_ORIGINS=* in System Environment Variables, then restart Ollama.

qwen3:8b is the recommended default — it balances quality, speed, and memory use (5.2 GB). On an M-series Mac with 16 GB+ RAM you can run qwen3:14b for noticeably better output.

For math-heavy work, phi4:14b excels. For visible chain-of-thought reasoning, try deepseek-r1:8b. For the fastest edits, llama3.2:3b is very quick.

You can download and switch models directly from the Local Models section of the Options page — no terminal needed.

Open the Corollary Options page (right-click the extension icon → Options, or click the gear icon in the sidebar). Go to API Keys and paste your key into the relevant field. Keys are stored locally in chrome.storage.sync and are never sent to Corollary's servers.

After purchase, your license key (lm_live_…) arrives by email. Open the Options page, go to Corollary Cloud, and paste the key into the license field. The extension validates it once and then stores it locally.

The Cite tab searches Overleaf's file tree for .bib files associated with your project. Make sure your .bib file is uploaded to the project (not just referenced externally). If you have multiple .bib files, the tab searches all of them.

For paper search, Corollary queries Semantic Scholar. Results may take a few seconds on first load.

Yes. Corollary works with any Overleaf account — personal, institutional, or premium. It runs as a browser extension on top of the standard Overleaf editor.

No. Corollary reads only the text you actively select or the cursor context you request. It does not crawl, index, or upload your documents. In local mode, nothing leaves your machine at all. See the Privacy Policy for full details.
