AI document search that tells you where the answer is

Search+ is an AI document search tool for the PDFs you collect for a project. Instead of typing keywords into a box, you ask a question in plain language, and Search+ looks through every document in the workspace, or only the one you choose, and answers with inline citations to the passages it used. Upload your PDFs, wait for them to finish processing, then ask where a topic, figure or commitment appears and open the excerpt to check it.

No payment details needed to create an account.

What a search looks like in Search+

Each search is a question you type into the workspace chat. These are the kinds of questions people ask when they are hunting for something inside a stack of PDFs, and what comes back.

Where does the contract set mention termination for convenience?

The answer names each PDF that discusses the topic, says what it says in a sentence or two, and attaches a citation per point. Each citation opens the supporting excerpt, with a page or section reference when the PDF provides one.

Which of these reports gives a figure for staff turnover?

Search+ points you to the documents that contain the figure and quotes the surrounding passage through the citation, so you read the number in its own context rather than trusting a paraphrase.

What does the board pack say about the office move?

The answer pulls the relevant passages from the minutes and papers in the pack, says which meeting or paper each comes from, and cites them so you can read the discussion in full.

Find the section of the handbook that covers expenses.

Narrow the question to the handbook alone and the answer stays inside that one file, with citations that carry its section headings when the PDF has them.

What is AI document search?

AI document search is a way of finding information inside documents by describing what you need rather than guessing the exact words the author used. The system reads the documents ahead of time, breaks them into passages, and when you ask a question it retrieves the passages whose meaning matches the question, then writes an answer from them. Search+ applies this to the PDFs in one workspace at a time: it retrieves relevant passages by meaning, answers in prose, and links every claim in the answer to the excerpt it came from, so the search result is both the answer and the evidence.

Not the same as a web search engine. Search+ only searches the PDFs you uploaded to a workspace, never the internet, and it has no keyword search box: you search by asking.

How to search your documents with Search+

  1. Create a workspace for the collection

    Give the project a workspace so every document you want searched sits in one place. You can rename or archive it later.

  2. Drop in your PDFs

    Drag and drop up to 10 PDFs per batch. Each file shows its status while it is processed in the background, and it becomes searchable once it is indexed.

  3. Ask where something is

    Type the question the way you would ask a colleague who has read everything: where is this discussed, which document says that, what does the policy say about this. Keep the scope on the whole workspace or pin it to one file.

  4. Open the citations

    Every point in the answer carries a citation. Open it to read the excerpt, and use the page or section reference, when the PDF has one, to find the passage in your own copy.

What Search+ gives you when you search documents

Questions instead of query syntax

You describe what you are looking for in plain language. There are no operators, filters or exact phrases to get right.

Matches by meaning

Relevant passages are found by what they mean, not only by the exact words, so a question about cancelling finds a clause that talks about termination.

One answer across the collection

A single question can draw on several PDFs at once, so you see every place a topic comes up instead of opening files one by one.

Search one file when you need to

Narrow the scope to a single document when the question is about that file and nothing else.

Results you can verify

Each statement links to the source document and the supporting excerpt, and Search+ does not invent page or section locations a document does not contain.

Searches you can come back to

Conversations are saved with the workspace, so last week's search and its citations are still there when you return. Find old conversations by name.

What Search+ document search does not do

No keyword or full-text search box

There is no box that lists every exact occurrence of a word. If you need every literal match, use your PDF reader's find function alongside Search+.

No web results

It only searches the documents in your workspace. It will not pull in pages from the internet to fill gaps.

Answers can miss things

AI answers can be incomplete or inaccurate. Treat the citations as the result and check them before you rely on an important finding.

Search+ compared with searching PDFs by hand

Most people search a document collection with their PDF reader's find function, one file at a time. Here is how that compares.

AI document search questions

What is an AI document search tool?
It is software that finds information in your documents from a plain-language question rather than exact keywords. Search+ is one: it searches the PDFs in a workspace by meaning and answers with citations to the passages it used.
Is Search+ a document search engine?
It works like a search engine for the PDFs you upload, but the result is a written answer with citations rather than a ranked list of links. It does not search the web or your computer, only the documents in your workspace.
Is Search+ 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.
Does Search+ use retrieval-augmented generation (RAG)?
The approach is the same idea. Search+ retrieves passages from your documents by meaning and then writes the answer from them, citing each passage. Citations point to stable source ids that the backend resolves, so the AI cannot make up a citation location.
Can I search for an exact phrase?
Not as a keyword search. There is no full-text search box in Search+. You can ask a question that includes the phrase, and the answer will cite the passages that discuss it, but it will not list every literal occurrence.
How many documents can one search cover?
A search covers every indexed PDF in the workspace you are in, or a single document if you narrow the scope. You add files up to 10 at a time, and each one is searchable once its status shows it is indexed.
Is it free to try AI document search in Search+?
You can create an account without entering payment details and then upload PDFs and start asking questions.
What files can I search with AI here?
Search+ takes PDF, Word (DOCX) and Excel (XLSX) files, and OCR reads scanned documents so their text can be found too. Once a file shows as indexed, your questions in that workspace reach it, and the cited answer names the file where each passage was found.

Stop opening files one by one

Put the collection in one workspace and ask where the answer is.
