What goes wrong when a document is never properly analysed? It gets approved. Somebody reads it once, nothing obvious jumps out, and the weak argument in the third section survives into a decision. AI Text Analyzer exists to give a document the second reading that nobody has time for.

What is AI Text Analyzer?

AI Text Analyzer is a free browser tool that reads a piece of text critically. Its prompt box asks for what you want analysed, and the input can be anything argumentative: a proposal, a report, a policy draft, a set of customer responses, a piece of writing you are about to send.

Eight analysis angles

Overview, strengths and weaknesses, opportunities, risks, trends, gaps, comparison or recommendations, each producing a genuinely different read.

Risk flagging

Surfaces claims that would not survive a challenge, which is the most useful thing to know before sending anything.

Data and numbers

A toggle that pulls the figures out of the prose so you can see what the argument actually rests on.

Rigor slider

Decides how much support a claim needs before the analysis lets it stand unchallenged.

Six output shapes

Summary, report, bullets, table, scorecard or SWOT, depending on whether the analysis is for you or for a meeting.

Why Use AI Text Analyzer?

Because you cannot analyse your own writing. You know what you meant, which means you read the intention rather than the words, and the gap between the two is invisible to you and obvious to a reader who arrives cold.

The second reason is timing. Analysis is worth most before a document is sent, and that is exactly the moment when nobody wants to spend an hour on it. Making it a five minute step means it actually happens at the point where the findings can still be acted on.

What works well

  • Reads what is on the page rather than what was intended.
  • Separates supported claims from asserted ones.
  • The angle is chosen rather than assumed, so two runs give two useful reads.
  • Free, so analysing a draft before sending costs nothing.

What to watch for

  • It analyses text, not the world, so it cannot tell you a supported claim is wrong.
  • A high rigor setting on informal writing produces findings you do not need.
  • Strip identifiers before pasting anything a customer or colleague wrote.

Caution An analysis says whether a claim is supported inside the document. It cannot say whether the claim is true. Those are different questions and only one of them the tool can answer.

Who Should Use It?

Anyone about to send something that will be scrutinised. Bid writers checking an answer before submission. Managers reviewing a proposal from their team. Consultants pressure testing a report. Students checking whether their argument holds. Editors deciding whether a piece is finished.

How Does AI Text Analyzer Work?

The tool sits on one page. Its prompt box carries the placeholder Paste or describe what you want analyzed for the text analyzer. Below it is the model row, and whichever model is selected there handles the run. The advanced options accordion and the generate button follow.

The analysis arrives in a card with a running word count in the footer, which is a small but genuine help when the analysis itself has to fit into a review document. Copy, listen, reuse, download and open in full view sit on the card, a DOC, TXT and HTML export row runs alongside, and the session history panel keeps each run listed below.

Step-by-Step Guide

  1. Decide what you actually want to know before choosing any setting.
  2. Paste the text, stripped of anything personal.
  3. Pick a model.
  4. Set the analysis focus to your question rather than to Overview by reflex.
  5. Set rigor to match how much scrutiny the document will face.
  6. Generate, then rerun on a second focus if the first read raised something.

A short check before you rely on an analysis:

  • ✅ You pasted the whole argument, not one section of it
  • ✅ The focus matches the question you brought
  • ✅ Rigor matches the scrutiny the document will actually face
  • ✅ Personal identifiers were removed first
  • ✅ You know which findings are about support and which are about accuracy

Advanced Options Guide

The accordion sits closed beneath the model row, and opening it is the second thing most people do. It matters from the second run, when you know what you want to interrogate.

Custom InstructionsFree text up to 1000 charactersName the reader who will scrutinise thisTry "analyse as a sceptical procurement officer looking for unanswered requirements"

Tip Naming the sceptical reader in Custom Instructions changes the analysis more than any dropdown does. An analysis with a specific reader in mind finds different things from a general one.

Example Inputs

The most useful input is a whole argument rather than an extract. Here is a realistic paste into the AI Text Analyzer:

Analyse as a sceptical procurement officer looking for
unanswered requirements. High rigor. Flag anything asserted
without support.

"Our approach reduces onboarding time significantly. We have
worked with organisations of a similar size and have always
delivered on schedule. Our team is highly experienced and our
process is proven. Implementation typically takes six to eight
weeks, although this can vary depending on circumstances. We
will assign a dedicated project lead throughout."

Six sentences, five of which assert something and none of which supports anything. That is a very common shape for a submission paragraph, and it is exactly what a rigorous analysis is for.

Example Outputs

With focus on Gaps, rigor high and the procurement reader named, the analysis returned this:

UNSUPPORTED CLAIMS

"reduces onboarding time significantly"
  No baseline, no comparison, no figure. Unassessable.

"organisations of a similar size"
  Similar in what respect? Sector, headcount, complexity?

"always delivered on schedule"
  Absolute claim with no evidence. A single counterexample
  from a reference call destroys it. Weaken or support it.

"highly experienced" / "process is proven"
  Both are assertions about quality with nothing behind them.

CONDITIONAL LANGUAGE THAT REMOVES THE COMMITMENT

"typically takes six to eight weeks, although this can vary"
  This states no obligation. A procurement reader will treat
  it as no timescale offered at all.

WHAT IS ACTUALLY COMMITTED
One thing: a dedicated project lead.

That closing count is the most uncomfortable line in the report and the most useful. A paragraph of confident writing that commits to exactly one thing is worth knowing about before somebody else points it out.

Pro tip Run the analysis, make the edits, then run it again with identical settings. The second report is where you find out whether you fixed the claim or simply reworded it, which is a distinction that is very hard to judge from the inside.

FindingWhat it usually meansWhat to do about it
Unsupported claimAn assertion with nothing behind itAdd evidence or weaken the wording
Absolute languageA claim one counterexample destroysQualify it before somebody else does
Conditional commitmentWording that promises nothingCommit properly or remove the sentence
Gap against a requirementSomething asked for and not answeredAnswer it, even briefly

Once the edits are made, a compression pass with the AI Text Summarizer is a quick way to check that the argument still reads clearly when reduced to its bones.

AIToolsay is the starting point for the rest of the workflow, and an analysis is only useful if something follows it. The findings become edits, the edits need rewriting, the rewritten version usually needs checking again, and eventually the whole thing needs shortening to fit. Each has a tool of its own, and the layout is constant from one to the next: the same prompt box, the same model row, the same options accordion, the same export controls, the same session history panel. Every one of them free, every one open, and every one compatible with the last.

Frequently Asked Questions

Is AI Text Analyzer free?

Yes, and unlimited in practice, since nothing counts your runs.

Can it tell me whether a claim is true?

No. It tells you whether a claim is supported within the text you gave it. Verifying the claim against the world is a separate job.

What is the most useful focus setting?

Gaps for anything that must answer requirements, Strengths and Weaknesses for a draft you wrote yourself, Risks for anything going to a sceptical reader.

Should I analyse the whole document at once?

Analyse the whole argument, but section by section for a long document. An argument split across two runs cannot be assessed as an argument.

Why does it flag things I thought were fine?

Usually because rigor is set high. That is the point of the setting, and lowering it for an internal draft is entirely reasonable.

Can I use it on someone else's writing?

Yes, and it is a fairer reviewer than a person with an opinion about the author. Strip identifiers first as a matter of habit.

Run it on the paragraph you are proudest of. That is where the unsupported claims usually live, because confident writing and evidenced writing feel identical from the inside.
