IvyPanda GPT Essay Checker
Vendor IvyPanda Official site ivypanda.com/tools/gpt-essay-checker How this card is sourced
Updated · AI Detector Index editors
IvyPanda's GPT Essay Checker classified 77% of 126 documents correctly in Walters 2023 and returned no incorrect verdict at all, calling the remaining 23% uncertain, a record shared only with Copyleaks, Turnitin and Originality.ai among the 16 detectors (DOI 10.1515/opis-2022-0158, Table 4, read 8 November 2026). The tool is a free page on IvyPanda, a study-help site that gives its address as 30 N Gould St #41205, Sheridan, WY 82801 and signs the page "IvyPanda's editorial team and in-house developers created this online tool for you" (ivypanda.com/tools/gpt-essay-checker, Updated Jun 30th, 2025, read 10 November 2026). The card is one of the text detectors in the detector index, and how this card is sourced explains why a tool that calls itself "a free beta test" and never gave a wrong answer in its one study ranks where it does.
What the GPT Essay Checker detects
| Field | Value | Source |
|---|---|---|
| Content types detected | Text | ivypanda.com/tools/gpt-essay-checker |
| Generators covered | ChatGPT and GPT (It is up to you to decide if the text is Chat GPT generated or not; the FAQ defines GPT as the third generation of Generative Pre-trained Transformer developed by OpenAI) | ivypanda.com/tools/gpt-essay-checker |
| Input limits | Paste-only web tool: Enter the text with a counter reading 4500 characters left (the box's maximum is 4,500 characters), then Check My Essay. The result is a colour-coded word map with diagrams: Your text was likely generated by an AI if it is mostly red with some orange words; Your text looks unique and human-made if our GPT essay checker adds plenty of orange, green, and blue to the color palette. The page calls it a free beta test that will be improved later. No file upload and no API is published. | ivypanda.com/tools/gpt-essay-checker |
| Free tier | Free with no stated quota: Like ChatGPT itself, our GPT checker is free to use. In addition, it does not contain intrusive advertising; the tool shows no sign-in prompt, and the Brand Guidelines page says all materials are forever free, requiring no registration for access | ivypanda.com/tools/gpt-essay-checker |
| Data retention | Privacy Policy (Last updated: October 25, 2023): All User-submitted information at IvyPanda will be stored in our database. You may access and change any provided information via your personal account. [...] If you wish us to delete all your data and database records, please contact us via email [...]. Your records will be removed in 2-3 business days. The policy states nothing about text pasted into the tools and no period. | ivypanda.com/privacy-policy |
| Ownership | IvyPanda (IvyPanda.com; the Terms and Conditions, Last updated: December 13, 2024, define We, Us or Ours as IvyPanda.com and leave the governing-law clause blank: the laws without regard to principles of conflict of laws). Site footer: US Office: 30 N Gould St #41205, Sheridan, WY 82801, USA. Page byline: IvyPanda's editorial team and in-house developers created this online tool for you; Updated: Jun 30th, 2025; JSON-LD datePublished 2025-03-13 at the /tools/ address. The tool stood at ivypanda.com/gpt-essay-checker from the Wayback capture of 19 March 2023 with the same 4,500-character box, so it existed when Walters 2023 tested IvyPanda in June and July 2023. | ivypanda.com/terms-conditions |

The page sets the task in one line: "This GPT detector will help you decide how likely an essay or another assignment is to be written by a human or by AI. Just paste it into the field below, click the button, and check the result!" (ivypanda.com/tools/gpt-essay-checker, read 10 November 2026). The output is a colour map rather than a percentage. Under "How to Interpret the GPT checker result" the page explains: "Your text was likely generated by an AI if it is mostly red with some orange words. This means that the word choice of the whole document is nowhere near unique or unpredictable. Your text looks unique and human-made if our GPT essay checker adds plenty of orange, green, and blue to the color palette." The method section describes predictability as the signal: "An AI-generated text is too predictable. Its creation is based on the word frequency in each particular case." That is the word-by-word colouring the GLTR demo uses, and the IvyPanda page leaves the verdict to the reader: "It is you who decides whether the text is written by a human or AI."
ChatGPT is the only generator the page names, in "It is up to you to decide if the text is Chat GPT generated or not", and its FAQ defines GPT as "the third generation of Generative Pre-trained Transformer developed by OpenAI" (read 10 November 2026), so the card's generator count is one. No language is stated. The tool has stood on the site since at least 19 March 2023, when the Wayback Machine captured it at ivypanda.com/gpt-essay-checker with the same 4,500-character box it has today, which places it on the site in the June and July 2023 window of Walters 2023 (archived page, captured 19 March 2023, read 10 November 2026). The nearest cards are GLTR, whose colour method the page echoes, and Sapling, the Walters 2023 detector with the largest uncertain share, 28% of the 126 documents (DOI 10.1515/opis-2022-0158, Table 4, read 8 November 2026).
Limits and plans
| Plan | Price | Limits | Checked on |
|---|---|---|---|
| GPT Essay Checker | Free | 4,500 characters per check; colour-coded result and diagrams; no sign-in prompt (read 10 November 2026). |
Input is paste only. The box reads "Enter the text" with a counter at "4500 characters left", and the field's maximum is 4,500 characters, about 820 words at 5.5 characters a word (ivypanda.com/tools/gpt-essay-checker, read 10 November 2026). No file upload, no API, no minimum and no daily figure is published. The tool is free: "It is free to use. Like ChatGPT itself, our GPT checker is free to use. In addition, it does not contain intrusive advertising", and the page shows no sign-in prompt, while the site's Brand Guidelines say "all materials are forever free, requiring no registration for access" (ivypanda.com/brand-guidelines, read 10 November 2026). No monthly allowance is stated, so the card sits in the second table of the free tiers ranking.
On retention the Privacy Policy, last updated October 25, 2023, speaks of accounts rather than tools: "All User-submitted information at IvyPanda will be stored in our database. You may access and change any provided information via your personal account", and "If you wish us to delete all your data and database records, please contact us via email [...]. Your records will be removed in 2-3 business days" (ivypanda.com/privacy-policy, read 10 November 2026). The policy says nothing about text pasted into the checker and states no period, so the retention rank field is empty and the clause is quoted in the unranked table of the data retention ranking. The Terms and Conditions, last updated December 13, 2024, define "We" as IvyPanda.com and leave the governing-law sentence blank, reading "the laws without regard to principles of conflict of laws" (ivypanda.com/terms-conditions, read 10 November 2026).
What the vendor claims
No accuracy figure published. Our GPT checker doesn't give a definitive answer. It's only a free beta test that will be improved later. For now, it provides a preliminary conclusion and analyzes the provided text, implementing the color-coding system. It does work: Our GPT checker is based on the brand-new technology. Therefore, unlike traditional plagiarism checkers, it can actually detect AI-generated texts.
IvyPanda claims no accuracy figure and says so plainly. "Our GPT checker doesn't give a definitive answer. It's only a free beta test that will be improved later. For now, it provides a preliminary conclusion and analyzes the provided text, implementing the color-coding system" (ivypanda.com/tools/gpt-essay-checker, read 10 November 2026). The benefits list is bolder in tone but still carries no number: "It does work. Our GPT checker is based on the brand-new technology. Therefore, unlike traditional plagiarism checkers, it can actually detect AI-generated texts." With no percentage there is nothing for the claim versus evidence gap to compute, and no false positive rate is published.
The page makes no statement about paraphrased or humanized text. The same Tools menu lists an "Online AI Humanizer", and the home page links a blog guide titled "How to make AI-generated text undetectable" (ivypanda.com, read 10 November 2026), so the site sells the detector's counterpart two clicks away.
What independent studies found
- AIDI-S-0003Walters 20232023
IvyPanda: 77% of 126 documents correct, 0% incorrect, 23% uncertain (Table 4), one of four detectors with no incorrect response overall (with Copyleaks, Turnitin and Originality.ai); 71% of 84 AI papers correct, 0 called human, 29% uncertain; 100% of 42 GPT-3.5 papers correct; 43% of 42 GPT-4 papers correct, 0 called human, 57% uncertain; 88% of 42 human papers correct, 0 called AI, 12% uncertain. Tested June 25 to July 12, 2023.
One record in the studies index tested the tool. Walters 2023 ran IvyPanda between June 25 and July 12, 2023 on 42 ChatGPT-3.5 literature reviews, 42 ChatGPT-4 literature reviews and 42 human-written first-year composition papers. Table 4 prints 77% of the 126 documents correct, 0% incorrect and 23% uncertain; on the 84 AI papers 71% correct, 0 called human and 29% uncertain; 100% of the GPT-3.5 papers correct; 43% of the GPT-4 papers correct with 57% uncertain; and on the 42 human papers 88% correct, 0 called AI and 12% uncertain (DOI 10.1515/opis-2022-0158, Table 4, read 8 November 2026). IvyPanda was one of four detectors with no incorrect response on any document, and the only one of the four that did not also reach 98% correct: it bought its clean error record with one of the four largest uncertain shares in the study, behind Sapling's 28%, Content Detector AI's 27% and SEO.ai's 24% in the same table.
The fields follow the index rules. Both ranked error values stay empty: Table 4 prints 0 of 42 human papers called AI and 0 of 84 AI papers called human (DOI 10.1515/opis-2022-0158, read 8 November 2026), but the study record prints no per-tool figure for IvyPanda in either direction, the rule for this wave takes a Walters value only where the record prints one, and an uncertain verdict on 57% of the GPT-4 papers is neither a catch nor a miss. The data file carries the Table 4 figures in both field bases so a merge can rank them. Read as a classroom tool, the result says IvyPanda declined to accuse any of the 42 human writers and declined to decide on more than half of the GPT-4 essays.
Where IvyPanda appears in the index
Rankings
- AIDI-R-01AI detectors ranked by independent testing Two records added in the fifth wave on 9 November 2026, Pegoraro 2023 and Fleckenstein 2024, changed nine counts and none: Pegoraro 2023 tested ZeroGPT, GPTZero, Copyleaks, Originality.ai, Writer, Content at Scale (BrandWell), DetectGPT, the GPT-2 Output Detector and GLTR, lifting GPTZero to 12, the GPT-2 Output Detector to 10, Copyleaks to 7 and Originality.ai and ZeroGPT to 6; Fleckenstein 2024 tested 289 teachers and no software, so it counts for no card ([Fleckenstein 2024 record](/studies/fleckenstein-2024-teachers/)). Illuminarty, one of four cards added in the same wave, joined with its one image record from Ha and Passananti 2024, so 18 of 72 cards now qualify.
- AIDI-R-05AI detectors ranked by maximum input per check
- AIDI-R-17AI detectors ranked by the generator models the vendor names
Fits these use cases
- Not listed in a use-case view at this index version.
IvyPanda ranks on one study record in independently tested detectors, at 4,500 characters in the input limits ranking and at one named generator in generator models named, read in the data file on 10 November 2026. It appears in the GPT-4 question at 43% of 42 GPT-4 papers. It does not appear in the false positive, false negative, language, retention or claim gap rankings, because the record names no per-tool error figure for it and the vendor publishes no language, no period and no accuracy figure.
Every detector card on the register shows IvyPanda with the same fields as the paid tools, so a student who meets a red-and-orange colour map can see that the one study which scored the tool never saw it call a human paper AI.
