WisPaper: Your AI Scholar Search Engine

In the age of information overload, the challenge isn't finding papers—it's finding the right papers. WisPaper redefines your literature review workflow with two powerful modes: the default Deep Search for AI-powered search, and Quick Search for unlimited, free keyword retrieval.

Deep Search: AI That Reads, Not Just Matches

As your default research engine, Deep Search goes beyond simple keywords. It reads abstracts and context just like a human researcher.

Logic-Aware Filtering:

Need to find "Time-series models using Transformer but excluding LSTM"? Deep Search understands complex logic in natural language, filtering out 90% of noise that doesn't fit your experimental criteria.

Intent Understanding:

Whether resolving acronym ambiguity (e.g., "GEO") or identifying SOTA (State-of-the-art) papers, our AI helps you curate a high-quality reading list before you even open Zotero.

Daily Free Quota:

Enjoy 3 free AI deep searches every day—perfect for a deep dive into any specific sub-field.

Quick Search: The Familiar Speed of Google Scholar

When you need broad retrieval or already know a paper's title, Quick Search is your reliable, high-speed partner.

Forever Free, Unlimited:

We believe basic search should be accessible to everyone. Quick Search is completely free with no daily limits.

Lightning Fast:

Built on high-performance keyword matching, it offers an experience similar to Google Scholar. Ideal for quickly verifying citations, finding specific authors, or locating PDF downloads.

Frequently Asked Questions

What is the difference between Deep Search and Quick Search?

Scholar Search offers two complementary modes:• Deep Search (Default): Our core AI Reading Engine. Best for Literature Reviews, resolving ambiguity, and logical filtering.• Quick Search: A high-speed Keyword Search Engine offering a familiar experience like Google Scholar. Best for specific lookups, completely free with unlimited searches.

Why use Deep Search if I already have Google Scholar?

Google Scholar is great for broad retrieval but struggles with logic. E.g., searching for "Method A without Dataset B" often returns papers with both.Deep Search reads abstracts to filter out papers that don't match your logic, acting as the ultimate AI Filter before you build your Core Reading List.

Why does Deep Search return fewer results but higher accuracy?

Because Deep Search performs strict AI Noise Reduction. Traditional engines match any keyword occurrence. Deep Search analyzes context to see if a paper is "based on BERT" or just "mentions" it, filtering 90% of noise to deliver only relevant SOTA papers.

Is Scholar Search free to use?

Yes, we offer a tiered plan:• Quick Search: Forever free with unlimited searches.• Deep Search: Free users get 10 free AI Deep Searches per day. usually sufficient for a daily deep dive into a specific research sub-field.

What happens if I use up my daily 10 Deep Search quota?

The system will notify you. You can:1. Switch to Quick Search: Continue searching for free (keeping keywords).2. Upgrade: Unlock more AI quota.3. Wait: Quota resets automatically the next day.

How does Deep Search improve my research efficiency?

Think of Deep Search as your "Smart Gatekeeper." Use it to filter noise and rapidly curate a high-quality "Must-Read List" (20–50 papers). This prevents you from downloading irrelevant PDFs, ensuring your energy is spent only on the most valuable research.

Which mode is better for researching new trends (e.g., on arXiv)?

Deep Search is best. New fields (especially on arXiv) often have ambiguous terms (e.g., "GEO"). Deep Search uses Domain Knowledge to infer intent from context, ensuring you find the right pioneering work.

I already know the title and just want the PDF. Which mode?

Switch to Quick Search. For specific info, it responds in under 1.5 seconds, similar to Google Scholar, helping you verify info and find text immediately.
