AI PDF analyzer for questions that go past a summary

Search+ is an AI PDF analyzer for the questions that come after a summary: what are the themes, which claims are supported, where the argument is weak, and which passage a conclusion depends on. You upload PDFs to a workspace and ask those questions in plain language. Answers are written in prose and cited to the excerpts they use, so analysis stays tied to the text.

You can sign up without payment details.

Analysis questions and what they return

Examples of analytical questions. Results depend on the PDFs you provide.

Which claims in this paper are backed by data, and which are opinion?

Claims sorted by how the document supports them, each cited to the passage that either presents evidence or simply asserts the point.

Trace the conclusion on page 40 back to its evidence

The chain of passages the conclusion relies on, cited in order, so you can see whether the support is as strong as the wording.

What themes recur across these PDFs?

Recurring themes listed with citations to each document where they appear.

Where does the document define its key terms?

The definitions as the document gives them, cited, which helps you read later sections with the author's meanings in mind.

What is an AI PDF analyzer?

The phrase covers two very different tools. One kind is a parser that turns PDF content into structured data: fields, tables, invoice line items. The other kind is a reading tool that helps you analyze what a PDF argues. This page is about the second kind. It reads the text of your PDFs, finds the passages relevant to your question by meaning, and writes an answer that cites those passages. That makes it suited to analytical reading: evaluating arguments, mapping themes, checking whether a conclusion follows from the evidence, and comparing how several documents treat the same question.

Not the same as a PDF editor. Search+ reads your PDFs and answers analytical questions about them with citations; it does not change the files.

How to analyze PDFs with Search+

  1. Create a workspace for the analysis

    Keep the PDFs you are analyzing together, separate from unrelated material.

  2. Upload and wait for indexing

    Drag and drop the PDFs, up to 10 per batch, and wait for each to show as indexed.

  3. Ask one analytical question at a time

    Specific questions give sharper answers than broad ones. Narrow the scope to one PDF when the question is about a single document, and widen it to the whole workspace when you want patterns across documents.

  4. Test the answer against the source

    Open each citation and read the excerpt. If the support looks thin, ask a follow-up about that passage. The conversation is saved, so you can return to the thread and continue the analysis later.

What the analyzer supports

Claim tracing

Trace a claim back to the passages that support it.

Themes and repeated claims

Find themes and repeated claims across a set of documents.

Comparison by question

Ask where two or more documents differ and get citations to each source.

Excerpts behind every answer

Open a citation to read the excerpt behind the answer.

Meaning-based retrieval

Passages are found by meaning, not only by exact words, inside the workspace you choose.

Scope control

Ask across every PDF in the workspace or narrow to a single document.

Work that persists

PDFs and conversations stay saved in the workspace, so an analysis can continue over days and pick up where it stopped.

Analysis standards you define

Put evidence standards or exclusions in Workspace Context and they apply to every question.

Themes that repeat across PDFs

Ask across the whole workspace for the themes or claims that come up in more than one document. The answer lists them with a citation to each passage, so you can see whether a theme rests on one strong source or several weaker ones.

Limits of the analyzer

No export

Analysis answers stay in the conversation. There is no export to a file, so copy what you need into your own notes or report.

Charts are not analyzed visually

Tables and charts are read as text, not as images, so visual patterns in a chart are not analyzed.

Analysis needs your judgment

AI answers can be incomplete or inaccurate. Treat each answer as a lead to check in the cited excerpt.

AI PDF analyzer questions

Is this AI PDF analyzer online?
Yes. Search+ runs in the browser at app.searchplus.ai, with no software to install.
Is it free to try?
You can create an account without entering payment details. The app shows what your account includes after you sign up.
What kind of tool is it, exactly?
A web app that holds your PDFs in persistent workspaces and answers questions across them, citing the supporting excerpt for each answer.
Can it spot contradictions inside one PDF?
You can ask it to look for statements that conflict. The answer cites both passages so you can judge whether they really contradict each other.
Can it analyze a PDF full of charts?
Charts and tables are read as text, so analysis of chart-heavy documents is limited. It works best on PDFs where the argument is in the prose.
Can it compare the arguments of two PDFs?
Yes. Upload both to one workspace and ask how their arguments differ on a specific point. The answer cites the relevant passages from each document so you can weigh them side by side.
Does it find passages that use different wording?
Yes. Search+ retrieves passages by meaning, not only by exact words, so a question about cost can surface passages that talk about spending, budgets or prices.
Can it tell me which parts of a PDF are weakest?
You can ask it to point out conclusions that rest on little evidence or on a single source. Each answer cites the passages involved, so you can read them and decide for yourself whether the support is thin.
Will the analysis follow my own standards?
Write the standards into Workspace Context, for example treat unsourced figures as unverified, and Search+ applies them to every question in that workspace.
Can it analyze scanned PDFs or other formats?
Yes. OCR reads scanned PDFs, and Word and Excel files can be analyzed alongside them. The analysis is still written as an answer with citations, so each conclusion about a scanned page points to the excerpt it rests on.
