A browser extension that summarizes peer-reviewed research inline on your search results. Ask a question on Google, Bing, DuckDuckGo, Brave, Ecosia, Startpage, or Yahoo, and Truey fetches relevant papers from PubMed, Semantic Scholar, Europe PMC, arXiv, and/or OpenAlex, then summarizes the evidence with an AI model of your choice. It highlights the single clearest finding and shows a confidence level.
- Inline search cards: a "Truey" result card appears alongside your normal search results when your query looks scientific.
- Multi-source paper retrieval: PubMed, Semantic Scholar, Europe PMC, arXiv, and OpenAlex, with keyword-relevance ranking so off-topic papers get filtered out before reaching the AI.
- Bring your own AI provider: Groq, Ollama, llama.cpp, Grok, OpenAI, Anthropic (Claude), or any OpenAI-compatible custom endpoint.
- Configurable vocabulary level: plain English up to expert/researcher level, globally or per scientific domain.
- Evidence confidence bar: every summary ends with a Low/Moderate/High confidence rating based on the underlying studies.
- Privacy controls: local-only mode, optional history/abstract caching, all configurable from the settings page.
Truey is not yet published to an extension store, so install it as an unpacked extension:
- Clone or download this repository.
- Open
chrome://extensions. - Enable Developer mode (top right toggle).
- Click Load unpacked and select the
extension/folder inside this repo. - Pin the Truey icon to your toolbar.
- Clone or download this repository.
- Open
about:debugging#/runtime/this-firefox. - Click Load Temporary Add-on… and select
extension/manifest.json. (Temporary add-ons are removed when Firefox restarts. For a persistent install you'll need to sign the extension via AMO.)
After installing, click the Truey icon, then Settings (or the gear icon), and configure a provider under the Provider tab:
| Provider | Endpoint | API key needed? | Free? |
|---|---|---|---|
| Ollama | http://localhost:11434 |
No | Yes, runs locally |
| llama.cpp | http://localhost:8080 |
No | Yes, runs locally |
| Groq | https://api.groq.com/openai |
Yes, get one here | Free tier available |
| OpenAI | https://api.openai.com |
Yes | No, paid |
| Anthropic (Claude) | https://api.anthropic.com |
Yes | No, paid |
| Grok | https://api.x.ai |
Yes | No, paid |
| Custom (any other OpenAI-compatible API) | your endpoint URL | Depends on provider | Depends on provider |
Pick a model name your provider supports, save, and use Test connection to confirm it's reachable.
From the Sources and Filters tabs you can:
- Toggle which databases are queried (PubMed, Semantic Scholar, Europe PMC, arXiv, OpenAlex; Cochrane and bioRxiv are not yet implemented).
- Set a minimum citation count, a publication date range, and preferred study types (meta-analyses, systematic reviews, RCTs).
- Choose what happens when too few papers pass the filters: ask before proceeding, expand the search automatically, or summarize with whatever was found.
