What drove the change in operating margin this year, and what does management expect next?
answersDoc
Operating margin improved mainly because input costs fell and the year carried fewer one-off charges 1. The board minutes add that two price changes took effect in the second half 2. On the earnings call, management said it expects margins to hold steady next year as the savings level off 3.

How it works

From a pile of files to a cited answer in three steps

No setup and no technical skills. If you can upload a file and type a question, you can use answersDoc.

01

Add your sources

Upload files, paste text or add a YouTube link. answersDoc reads each source and indexes it, so it can find the exact passage later.

02

Group them in a bank

Wire related sources into one Answers Bank: a project, a case, a course or a whole research library. Add to it whenever you like.

03

Ask, then check

Ask in plain words. The answer cites its sources claim by claim, so you can open each passage and check it before you use it.

Why answersDoc

Built for research, not just one file

Plenty of tools let you chat with a PDF. answersDoc is built for the next step: many sources, one question, and an answer you can check.

Banks

Whole libraries in one bank

Keep each project in its own Answers Bank and keep adding to it. Banks are built for big collections, so a whole library can answer one question.

Answer depths

Fast, Normal or Research

Choose how hard answersDoc works on each question, from a quick answer to a full research pass across every source in the bank.

Citations

Every claim shows its source

Answers carry numbered source chips. Open one to see the passage it came from, and check it before you quote it.

History

Your conversations are saved

Every question and answer stays with its project, so you can pick up where you left off and show how you reached a conclusion.

Research mode

Many sources in, one clear answer out

Research mode is for the questions that need the whole library. It runs the full pipeline, then a heavier reasoning model organizes what it found across many sources into one answer, with the citations kept.

  • FastA quick, light answer when you just need the gist.
  • NormalThe full pipeline, with a citation on every claim.
  • ResearchThe deepest answer. Slowest, and the most thorough.

Who it is for

One research engine for many kinds of work

Researchers and analysts use it first, but any job that runs on documents can use the same three steps.

Research and analysis

Read across a whole literature instead of one paper at a time.

FAQ

Questions, answered

What can I upload?

PDF files, Word documents (.docx), EPUB eBooks, plain text and Markdown, notes you paste in, images, audio files and YouTube links. Each source is read and indexed, so answersDoc can find the exact passage later.

How is answersDoc different from a PDF AI chat?

answersDoc is built for more than one file. It answers from a whole bank of sources at once and cites each claim, so you can see which document said what before you rely on it.

What is Research mode?

It is the deepest of the three answer depths. Fast gives a quick answer. Normal runs the full pipeline and cites every claim. Research adds a heavier reasoning model that organizes findings across many sources; it takes longer and goes further.

Is my chat history saved?

Yes. Conversations are saved with your project, so you can come back to an earlier question and its answer. That helps in research, legal work and anywhere you need to show how you reached an answer.

Is there a Google Docs version?

Yes. answersDoc also runs inside Google Docs as a Google Workspace add-on, listed on the Google Workspace Marketplace.
