What’s New on PACR (Fall Update): AI Filters, Dynamic Answers, and Daily Research Updates
Sep 30, 2026
Research questions need different kinds of evidence and different kinds of answers. Sometimes you need a quick explanation. Sometimes you need a detailed comparison of studies. And sometimes you simply want to know what has changed in your field.
The latest updates to PACR give you more control over the literature your AI answer draws from, responses that adapt to your question, and daily research updates directly on your homepage.
1. AI Filters: Choose the Literature Behind Your Answer
The usefulness of an AI research answer depends on the papers behind it.
You might want to focus on recent publications, papers indexed in PubMed, or research from a particular geography. Those choices shape the evidence you need.
PACR’s AI filters let you narrow the literature before the response is generated. Available options include:
Publication year: Focus on a specific period.
Type of work: Narrow the kinds of publications considered.
Indexed status: Filter by indexing criteria.
Citation count: Set minimum or maximum citation thresholds.
Geography: Focus the literature by geography.
Open access: Prioritize openly accessible papers.
Journal quartile: Narrow your search by journal quartile.
For example, you could focus a literature review on open-access articles published within the past ten years, indexed in PubMed, and appearing in Q1 or Q2 journals.
These filters guide the literature PACR considers when building your answer. You define the scope before the synthesis begins, reducing the need to sort through irrelevant evidence afterward.
Choose filters that fit your question. Citation counts and journal quartiles can help narrow a search, but they do not replace assessing the quality of an individual study.
2. Dynamic AI Responses: Answers That Fit Your Question
A comparison question needs a comparison. A request for a table needs clearly organized rows and columns. A question about conflicting findings needs an explanation of where the evidence disagrees.
PACR’s Research Assistant now adapts its response to what you ask.
You can request:
A concise summary to understand a topic.
A comparison to examine differences between treatments, methods, or findings.
A structured table to review specific details across studies.
A breakdown of conflicting evidence to understand uncertainty in the literature.
For example, instead of asking:
What does the research say about treatments for obesity?
You could ask:
Compare semaglutide and tirzepatide in adults with obesity without diabetes. Present a table covering weight loss, cardiovascular outcomes, safety, and weight regain after treatment discontinuation.
That request tells PACR both what to investigate and how to organize the answer.
Or you could ask:
Where do studies disagree, and what differences in study design might explain those findings?
The response can then focus on disagreement rather than a general overview.
The more clearly you describe the result you need, the more directly PACR can structure its response around your research task.

3. Daily Research Updates on Your Homepage
Keeping up with research is an ongoing part of the work. New publications can change how you frame a question, interpret a finding, or plan your next study.
PACR now brings daily research updates directly to your homepage, surfacing new research in your field where you already begin your work.
You can check the latest updates when you open PACR, explore papers that catch your attention, and identify topics worth investigating further.
It gives staying current a place within your research routine, alongside the work you are already doing.
Put the Updates to Work
These three updates support a practical research workflow:
Check your homepage for daily research updates.
Set your AI filters to define the literature relevant to your question.
Specify the answer you need, whether that is a summary, comparison, table, or analysis of conflicting findings.
You control the scope of the evidence and the shape of the response, with new research available from the moment you open your workspace.
Science is already hard. A scientist’s workspace shouldn’t be.
