Pangram vs ZeroGPT: Free Limits and Vendor Claims Compared (2026)

Verdict: ZeroGPT if you want a no-signup check on a single passage. Pangram if you want a daily free allowance, a paid individual plan, and a vendor that describes span-level highlights. Neither vendor’s page gives an independent accuracy result in this comparison, so the choice rests on limits and workflow, not on a verified percentage.

Scorecard

Pangram’s free plan, pricing and feature descriptions come from Pangram’s pricing notes, checked on 2026-10-14. ZeroGPT’s input limit and accuracy wording come from ZeroGPT’s price guide, checked on the same day. The independent-evidence column comes from eesel AI’s rate sheet. Any cell reading “not recorded” has no supporting source.

Vendors revise these terms, so check each page before you buy.

Pangram’s edge

Pangram’s free plan allows up to 2,000 words a day, and its page describes it as twenty free checks each day. The Individual plan, at $20 per month or $15 per month billed annually, raises the allowance to 300,000 words a month and adds plagiarism detection on every scan. For a writer or editor who checks several drafts a week, the daily allowance is the clearest benefit in the table. Source: Pangram’s price guide.

Pangram’s page also describes section-by-section analysis, which shows which parts of a document look AI-written. That is a workflow choice: a reviewer can check passages instead of one score for the whole document.

ZeroGPT’s edge

ZeroGPT’s free check is the simpler offer. Its homepage shows an input box that reads 0 of 15,000 characters, and eesel AI’s review describes the same 15,000-character limit with no signup. That is useful for one passage that needs a quick second look. Source: eesel AI’s plan table.

ZeroGPT’s homepage also states 98.4% detection accuracy and under 1% false positives. Those are the company’s own figures. eesel AI’s review says it found no independent benchmark or published validation dataset for ZeroGPT, so those figures remain unverified in this comparison.

Reading the two accuracy statements

Pangram’s page uses qualitative wording about accuracy and false positives, and this comparison records it as wording only. ZeroGPT gives numbers, and they are vendor claims. Neither statement can be placed next to an independent result in the way a published benchmark can, so the comparison keeps both in the vendor column.

For a practical check, run each tool on text you already know: a passage you wrote, and a passage an AI model wrote. Compare what each tool says. A short test on your own material tells you more about fit than either homepage does.

Who each one suits

• Pangram: writers, editors and small teams who want a daily free allowance and a paid plan that scales to a team, and who value passage-level results.
• ZeroGPT: anyone who needs a one-time, no-signup check on a single passage and does not need a paid plan yet.

Before you use either

Check the current free limit before you build a routine around it, because both vendors change their allowances. Read each vendor’s privacy terms if the text is unpublished. Record the date, the tool and the text version you checked, so a later result can be compared with the earlier one.

Where the evidence ends

Neither tool was run on a test set here, and it does not report measured accuracy for either one. The free limits and prices come from the vendor pages and from eesel AI’s review as stated. The accuracy wording comes from each vendor’s own page. For the method used on this site, see the method page.
