LLM Backend (for citation ranking & paper review)

Works with any OpenAI-compatible API:

| Backend | Base URL | API Key? | |---------|----------|----------| | Ollama (default) | http://localhost:11434/v1 | No | | vLLM | http://your-server:8000/v1 | Optional | | OpenAI | https://api.openai.com/v1 | Yes | | OpenRouter | https://openrouter.ai/api/v1 | Yes | | Together | https://api.together.xyz/v1 | Yes | | Groq | https://api.groq.com/openai/v1 | Yes |

Ollama on Mac/Linux: By default, Ollama blocks requests from browser extensions. You need to allow Chrome extension origins before starting Ollama:
OLLAMA_ORIGINS=chrome-extension://* ollama serve
To set this permanently:
launchctl setenv OLLAMA_ORIGINS "chrome-extension://*"
Then restart Ollama. Without this, the reviewer will return a 403 error.

Paper Search APIs

Semantic Scholar — works without key (rate-limited)
Serper (Google Scholar) — optional, skipped if no key
OpenAlex — no key needed, email improves rate limits

Development

npm run dev    # build with watch mode

After changing code, go to chrome://extensions and click the reload button on the extension.
