Claude Free is a general chat service. You can ask it to point out vague claims, missing evidence or awkward transitions. An answer about how a paragraph sounds cannot establish who wrote it. Anthropic’s help page explains how to access the chat and what usage limits apply. Get started with Claude
If you are reviewing your own work, use the chat to raise questions you can answer by looking at your draft and sources. If someone has flagged a submission, start with the actual report and the review procedure.
Check the passage, then the evidence
- Locate the claim
- Point to one sentence that needs support.
- Find the source
- Open the notes, citation or earlier draft.
- Resolve the gap
- Clarify the claim, add the right citation or remove it.

What can Claude Free check?
A chat can suggest what a reader might find unclear. For instance, it might ask how you know a change was significant or who “they” refers to. Read the passage and check each suggestion yourself. A confident answer about authorship gives you no independent evidence of who typed the words or what assistance they used.
Claude Free has a session-based usage limit. Anthropic says availability varies with demand and that the limit resets on a five-hour cycle. Check the account’s message when you reach it. Claude Help Center on limits
Ask a question you can verify
For a draft you are permitted to share, try a short excerpt and a targeted request:
Quote up to three phrases from this passage where you cannot tell what happened, who did it, or what evidence supports the claim. For each, ask one question I can answer using my own notes. Leave the draft unchanged.
For example, suppose your draft says “The new schedule improved attendance significantly.” A question worth asking is “Which dates and counts are you comparing?” If your notes record 24 attendees at the first meeting and 29 at the second, you can state the counts. Whether the schedule caused the increase would require more evidence.

| Your question | Useful evidence | What to do |
|---|---|---|
| Which sentence needs revision? | The draft and a specific reader question | Revise the sentence or explain its context |
| Is this quotation accurate? | The original source and its location | Read both versions and correct the quotation |
| How did the author produce this passage? | Notes, drafts, version history and an account of the work | Follow the relevant review process |
What to do when a submission is flagged
- Keep the submitted copy and any feedback. A later edit can change the text or its page numbers.
- Ask which report and passage are under review. A writing indicator and a similarity report answer different questions.
- Gather the drafts, notes and cited material that help explain how the passage was written.
- Follow the school or workplace procedure and describe the tools you actually used, where relevant.
If your instructor mentions an asterisk or a percentage, check what the report actually displays. The Turnitin report guide explains the difference. Before uploading school or client material to any chat, check that you have permission to share it.
Frequently asked questions
Can Claude Free give me a verified AI writing percentage?
A chat estimate cannot verify who wrote the passage. For an existing report, ask which service produced it and what that report actually measures.
Can I check a quotation without sharing the whole draft?
Use the quotation and the relevant source excerpt if you have permission to share both. Compare the exact words and the surrounding context yourself.
Do short sentences or a formal tone prove AI authorship?
Those are style traits. Read the passage alongside earlier drafts, source notes and the assignment or workplace instructions.
What if my instructor can see a flag that I cannot?
Ask which report and passage are under review. Keep the submitted version so that you can match the wording and page numbers.
Is the free chat unlimited?
Anthropic documents a session limit with a five-hour reset cycle. Check the message shown in your account when you hit the limit.
