How does the interactive lesson work?

Each step is shown to you first (Watch). Then you do it yourself in a practice copy that checks every click (Your turn). If you get stuck, press Do it for me. It is a practice copy, so no Claude account is needed and nothing is sent to Anthropic.

Can Claude compare two versions of a document?

Yes. Paste both versions with a label on each, name the columns you want and tell Claude to use only the text provided. In our test it returned a table with Topic, 2025 version, 2026 version and What changed, plus lists of what was new and what stayed the same.

How do I see what changed between two documents with AI?

Ask for a table with one row per topic and a What changed column, then check each row against your two versions. The table is easier to verify than a paragraph, and the What changed column tells you which rows matter.

Does Claude get comparisons wrong?

It can. In our test the table was right, but the list called What was removed or reduced included things that had only been changed. When we pointed that out, Claude agreed nothing was truly removed. Read every list, not only the table.

Can I turn the comparison into an email to staff?

Yes. Ask for a short note and say it must use only facts from the table. In our test Claude wrote a five-sentence note. Check every number against the real document and have the policy owner confirm it before you send it.

Is it safe to paste a company policy into Claude?

Follow your employer's rules on AI tools. Take out names, client details and anything confidential, and use a plan and settings your firm approves. For contracts and legal terms, ask a professional before you rely on an AI summary.

Claude Compare Documents: What Changed Between Two Versions

Free · Live nowClaude for Everyday Work Claude~5 min9 stepsBeginner

Updated October 13, 2026. Built against the tool’s current screens and checked step by step. How we check this lesson

Every year somebody sends a new version of a policy, a price list or a handbook, and the question is always the same: what is different? Claude can lay two versions side by side in a table in seconds, but it can also file changes in the wrong list. In this free lesson you paste two versions of a made-up remote work policy into a practice copy of Claude, read the comparison, catch a mistake in its removed list, and get a short note to staff written only from the facts in the table.

Claude after the comparison prompt, with the pasted 2025 and 2026 remote work policy versions and the start of a table with Topic, 2025 version, 2026 version and What changed columns

What you will do: two versions in, a clear list of changes out

You are Dana at Birchwood Benefits Consulting, a made-up consulting firm. HR has sent the 2026 remote work policy, and your staff want to know what changed since 2025. The policy covers eligibility, core hours, equipment, approval, expenses and security.

In the practice copy of Claude you paste both versions in one message, each under a label, with the columns you want and the instruction to use only the text provided. You read the table and the lists, notice that the removed list is wrong, ask Claude to fix it and to write a five-sentence note to staff, check the note, and click the copy icon.

How to ask for a comparison that is easy to check

Our prompt asked for a table with four columns, told Claude to use only the text provided, and asked for three lists after the table: what is new, what was removed and what stayed the same. Putting a clear label above each version (2025 VERSION and 2026 VERSION) is what lets Claude line up the topics. Asking for columns gives you something you can scan and check, which a paragraph of prose does not.

In our test Claude returned a seven-row table: Eligibility, Core hours, Equipment, Approval, Expenses, Security and a new All-hands day row. It caught the small details, such as the stipend dropping from $50 to $40 and the notice requirement for schedule changes, and it marked the VPN rule as no change.

The mistake to look for: changes filed under removed

The three lists under the table were not all right. Claude's list called What was removed or reduced from 2025 included items that had only been changed, such as the 90-day eligibility period (now 6 months) and the once-a-year schedule approval (now quarterly). Nothing was truly removed. A reader skimming that list would think the firm had cut five benefits.

When we pushed back, Claude agreed that, strictly speaking, nothing was removed, and explained that the closest case was the sentence saying home office furniture is not reimbursed, which was replaced by the $200 allowance. Asking it to check its own list is an easy fix, and it is worth doing every time the lists will be shared.

From the table to a note staff can read

We then asked for a five-sentence note to staff using only facts from the table. Claude wrote one paragraph that covered the third remote day after six months, the new core hours, the monitor and the $40 stipend, the $200 allowance, quarterly approval with five business days notice, the first-Monday rule and the unchanged VPN requirement. Setting the limit (five sentences, facts from the table only) keeps the note short and stops Claude adding promises.

Read the note against the policy yourself. A table is easy to check, and a note built from it is only as good as your check. Have HR or whoever owns the policy confirm it before it is sent.

Mistakes to avoid

Pasting both versions with no labels. Claude has to guess which is which.
Skimming past the lists. The summary lists can mix up new, changed and removed, so read them like the table.
Trusting a summary of a contract or a legal policy. Use it to find what to read, and ask a professional before you rely on it.
Pasting private data. Take out names, client details and anything your employer says not to put into AI tools.
Sending Claude's note without checking every number against the real document.

Plans and limits

We tested in a Claude Max account in October 2026, with the text pasted into the message box. We also tried it with two small .txt files attached instead of pasted (the paperclip or plus in the message box), and Claude read both and built a correct table, with the 90-day wait changed to 6 months and the core hours ending at 2pm instead of 3pm. File types and limits depend on your plan. Features and limits change often, so check Claude's help pages for your account. Follow your employer's rules on what you can put into AI tools.

Try it yourself, free

Reading the steps is a start. Doing them is how it sticks. The interactive module walks you through every click in a practice copy of Claude, checks each step, and never touches your real accounts.

All 9 steps of the interactive module, in order. In the module you watch each one, then do it yourself in a practice copy that checks your work.

1. Paste both versions

Click the message box. You are Dana at Birchwood Benefits Consulting. HR has sent a new remote work policy for 2026 and you need to tell staff what changed. In Claude, click the message box.
You're Dana at Birchwood Benefits Consulting. HR sent a new remote work policy for 2026, and you need to tell staff what changed. In Claude, click the message box.

Paste both versions with clear labels. Paste the two versions, each under its own label, and say the columns you want and "use only the text below". Paste in the both versions.

Put a label above each one, say what columns you want, and tell Claude to use only the text below.

Compare these two versions of our remote work policy. Make a table with the columns Topic, 2025 version, 2026 version and What changed. Use only the text below. After the table, list what is new, what was removed and what stayed the same. 2025 VERSION: Eligibility: employees may work remotely up to 2 days a week after 90 days of employment. Core hours: 10 a.m. to 3 p.m. Eastern. Equipment: the company provides a laptop and a $50 monthly internet stipend. Approval: a manager approves a standing schedule once a year. Expenses: home office furniture is not reimbursed. Security: use the company VPN on any network. 2026 VERSION: Eligibility: employees may work remotely up to 3 days a week after 6 months of employment. Core hours: 9 a.m. to 2 p.m. Eastern. Equipment: the company provides a laptop and a monitor and a $40 monthly internet stipend. Approval: a manager approves a standing schedule each quarter, and changes need 5 business days notice. Expenses: a one-time $200 home office allowance. Security: use the company VPN on any network. Remote days may not be taken on the first Monday of each month, which is the all-hands day.
