Find sources
Enter a topic, or paste a passage you wrote, and find sources you can cite right away.
Enter your text
Type a topic, a question, or a passage of your own into the single box. The limit is 500 words. PerfectRefs marks the statements that need a source, based on their meaning, and searches for each one separately. A topic counts as one statement. Below the box, you will see how many sentences and words you entered, for example "1 sentence · 9 words".
Review the sources
Each statement that needs a source is underlined. A vermilion underline means sources were found. A gray underline means none were found. Click a statement and the Papers panel lists the sources for it, with details such as the bibliographic record, journal ranking, and relevant evidence.
To cite a source, tick the checkbox at the top right of its card (Tick to cite). A citation number then appears at that spot in your text.
Click Generate summary. The evidence on each card changes to that source's key points, an AI summary appears below your text, and the list is grouped by relevance. The key points and the overview are written from the abstracts, so check the original paper for accuracy.
Copy and export
There are three places to copy or export:
- The Export button at the bottom right of your text exports Text with citations: your text with a number at the end of each sentence, followed by a reference list.
- Export above the list exports the sources as a reference list in one of several citation styles, or as .ris, .bib, or .xlsx.
- Copy for the AI summary has two options. Copy text copies the text of the overview. Copy with citations copies the overview with in-text citations and adds a reference list.
Cite on a single card copies the citation for that one source.
Filters
The Filters panel lets you limit results by publication year, source level (Source rank, such as SJR quartile), and number of citations. If you change a filter on the results page, click Search again to apply it.
When there are no results
That statement shows "No results for this search." No credits are deducted. Loosen the filters and click Search again, or click New search in the sidebar and try different wording.
Tips
- A statement that names the subject of the research and the conclusion finds better matches than a general one.
- Every source in the list is a real record that the search returned.
- The list is found by topic relevance. It does not judge whether a source supports your statement.
- For how many credits each statement costs, and when nothing is charged, see Credits and billing
