AI research assistant

AI research assistant that answers from your own sources

Search+ is an AI research assistant that works from the source PDFs of your project rather than from the open web. You create a workspace for the project, add the papers, reports and other PDFs you are relying on, and ask questions in plain language. Each answer carries inline citations to the document and excerpt it came from, so you can see which source said what before you build on it. The workspace stays saved, so the project can run for weeks.

No payment details needed to create an account.

What a research session with Search+ looks like

A few questions a researcher might put to a project workspace, and what comes back.

"Which of my sources define the main term, and do they define it the same way?"

The answer lists the definitions it finds in the uploaded PDFs, each followed by a citation to the document and the excerpt. Where definitions differ, the answer says so and cites both sides.

"What evidence in these files supports the claim in my second chapter?"

Search+ returns the passages that bear on the claim, cited to their source. A page or section reference appears when the PDF provides one.

"Summarize what the 2019 report says about sample size."

With the question scoped to that one report, the answer draws only on that file, and each sentence that relies on the report points to the excerpt behind it.

"What did we conclude last week about the second data source?"

Open the earlier conversation from your history. The thread reopens with its workspace and scope, so you can continue the line of questioning instead of starting again.

What is an AI research assistant?

An AI research assistant is software that helps with the reading side of research: locating what your sources say, summarizing them, comparing them and keeping track of where each point came from. Tools in this category differ mainly in where their answers come from. Some search the web or a paper index and bring back new sources. Others work only on the material you give them. Search+ is the second kind. It answers from the PDFs in your workspace, it shows a citation for each supported point, and it keeps the workspace and its conversations so a research project can be picked up again days later. That makes it useful once you have a reading list and need to work through it carefully, rather than at the stage where you are still discovering what to read.

Not the same as a search engine for finding new papers. Search+ does not look outside the documents you upload.

How to set up Search+ as your research assistant

  1. Create a workspace for the project

    Name it after the study, thesis chapter or question you are working on. You can rename it as the project changes and archive it when the work is done.

  2. Add your source PDFs

    Drag and drop up to 10 PDFs at a time. Each file shows its status while it is processed in the background, and you can keep working while that happens. Processing time depends on the size and structure of each file.

  3. Write your standing instructions

    Use Workspace Context to record what should shape every answer in this project, such as the terms you use, the evidence standard you care about or the sources to treat with caution.

  4. Ask, check and continue

    Ask across all your sources or narrow a question to one document. Open citations to read the excerpts, and come back to the same conversation later from your history.

What Search+ does for a research project

Answers grounded in your reading list

Questions are answered from the PDFs in the workspace, which keeps the assistant inside the sources you chose to rely on.

A citation behind each supported point

Answers include inline citations to the source document and the supporting excerpt, and you can open a citation to read that excerpt.

Locations only when the document has them

Citations include page or section references when the PDF provides them. Search+ does not invent locations the document does not contain.

Whole-collection or single-source questions

Ask across every document in the workspace, or narrow the question to one source when you need to know what a single paper says.

Project rules applied every time

Workspace Context stores standing instructions for the project and applies them to every question asked in that workspace.

Research that survives the week

Workspaces, documents and conversations are saved. You can reopen an earlier thread or search your conversations by name.

Themes and repeated claims

Ask Search+ to find the themes and claims that recur across your sources, with citations to where each appears.

What this research assistant does not do

It does not search the web or find new papers

Answers come only from the documents you upload. Use a literature database or search engine to build the reading list, then bring the PDFs into Search+.

It does not format references

Citations point to your source documents and excerpts. Search+ does not produce a bibliography in APA, MLA or any other style.

It can be wrong

AI answers can be incomplete or inaccurate. Check the cited evidence before relying on an important claim, especially in work you will publish or submit.

Questions about using an AI research assistant

Is there a free AI research assistant in Search+?
You can create a Search+ account without entering payment details, then create a workspace and upload PDFs. Search+ does not advertise a free plan or a set of free limits, so treat it as an account you can open and try rather than a permanent free tier.
Is Search+ on GitHub or open source?
No. Search+ is a hosted web app that runs in your browser at app.searchplus.ai. There is no source code to download or self-host.
Can I use it for a long research project?
Yes. Workspaces, documents and conversations are saved between sessions, so a project can stay open for as long as you need. Create one workspace per project and archive it when the project ends.
Will it find sources I have not uploaded?
No. Search+ answers only from the PDFs in the workspace you are asking. That is deliberate: every supported point can be traced to a document you chose.
Can it tell me where two of my sources disagree?
Yes. Ask a comparison question across the workspace. The answer points out where the documents differ and cites each source, so you can read both passages yourself.
What kinds of research documents can I add?
Papers, reports, theses, white papers or book chapters you hold as PDFs all work as sources. Put the material for one project in one workspace so every question draws on the same set.
Can I keep different research projects separate?
Yes. Each workspace holds its own documents, Workspace Context and conversations. Questions asked in one workspace draw only on that workspace's documents.
Does it replace reading the sources?
No. It helps you locate and compare what the sources say. AI answers can be incomplete or inaccurate, so read the cited excerpts before relying on an important claim.
Can I add scanned papers or Word drafts?
Yes. Alongside PDFs, the research workspace accepts Word and Excel files, and OCR reads scanned papers and book chapters. That lets older scanned sources sit in the same project as your current drafts, and every answer still cites the source it drew on.
