Trusted sources

What are trusted sources?

The Trusted Sources tool gives you direct access to some of the world's most respected knowledge databases, all from within your WebGPT dashboard. Instead of manually visiting multiple websites and searching each one individually, you can search them all from a single interface and get cleanly formatted results.

This is particularly valuable when you are creating content that needs to be accurate and well-sourced. Whether you are writing a blog post about health topics and need PubMed citations, or researching a historical event using Wikipedia, the Trusted Sources tool puts reliable information at your fingertips.

How to use trusted sources

Searching trusted sources is straightforward:

1. Navigate to Trusted Sources
   From the WebGPT dashboard, go to Utility Tools → Trusted Sources Search, or click the Trusted Sources card on your dashboard.
2. Select a source from the dropdown
   Click the source selector dropdown and choose which database you want to search. Each source has a brief description next to its name to help you pick the right one for your needs.
3. Choose a language (if available)
   Some sources, like Wikipedia, support multiple languages. If the language selector appears, the language is automatically detected from your search term — type in Hebrew and the language switches to Hebrew, type in English and it switches to English. You can also manually override the detected language if needed.
4. Choose content type or sort order (if available)
   Some sources offer additional filtering options. Internet Archive lets you filter by content type (texts, audio, video, software, images). Many sources also offer a sort toggle to order results by relevance, date, popularity, or other criteria.
5. Enter your search term
   Type a descriptive search query in the search field. More specific queries tend to yield more relevant results. For example, "machine learning in healthcare" will give more focused results than just "machine learning".
6. Click Search
   Press the Search button to query the selected database. Each search counts toward your daily usage limit (see Usage limits below).
7. Browse the results
   Results are displayed in a clean, formatted layout. Each result typically includes:
   • Title of the article or resource
   • A brief excerpt or description
   • A direct link to the original source for further reading
   Click on any result to view more details or visit the original article on the source's website.

Use cases

Trusted sources can enhance your content creation workflow in several ways:

Fact-checking content

Before publishing an article, verify key claims by searching the relevant trusted source. For health claims, check PubMed or WHO. For general facts, check Wikipedia or Wikidata. For technical accuracy, check Stack Exchange or MDN. This extra step can prevent publishing inaccurate information and builds reader trust.

Finding citations and references

Adding citations from authoritative sources improves the quality and credibility of your content. Search PubMed, arXiv, or Semantic Scholar for academic papers, World Bank for development data, or GitHub for open-source references that support your article's claims.

Pre-writing research

Before creating an article on a new topic, spend a few minutes searching relevant trusted sources. This helps you understand the topic better, discover important subtopics you might have missed, and gather key facts to include in your content.

Enriching AI-generated articles

AI-generated content can sometimes lack specific citations or data points. Use trusted sources to find concrete facts, statistics, and references to add to your AI-generated articles, making them more authoritative and useful to readers.

Usage limits

Trusted source searches are subject to daily usage limits based on your subscription plan. Each search query counts as one use, regardless of which source you search.

The usage indicator on the page shows your current daily usage and remaining quota. When you reach your daily limit, the search button will be disabled until the next day.

For specific limits per plan, refer to the Plans & usage limits page.
