GPTZero vs Getsolved.ai (2026): Pricing, Features and Which to Choose

GPTZero suits teachers, schools and anyone who needs to check writing inside Google Docs, Google Classroom or Canvas, or prove their own work with a writing replay. Getsolved.ai suits writers and editors who want a quick check with sentence-level explanations, file uploads and more than 20 languages, without making an account. Both let you scan text for free: GPTZero's free box takes up to 10,000 characters, and Getsolved says its free checker needs no sign-up.

This guide compares the two AI detectors using only what each company says on its own website. Where a site did not show something, such as a price, we say so rather than guess.

Quick comparison

GPTZero: what it is and what it costs

GPTZero describes itself as an AI detector that checks whether text came from models such as ChatGPT, Claude, Gemini and Llama, and that also checks writing quality. Its FAQ says it was founded in January 2023 and works with organisations in education, hiring, publishing and law.

What you can do. The homepage lists several tools around the main detector:

• AI detector and Advanced Scan for classifying text from major AI models, with a more detailed scan for deeper results.
• Writing Replay in Google Docs, which lets you watch a document being written, see copy and pastes, and check for unnatural typing patterns. This is useful for students or writers who want to prove they wrote something themselves.
• Plagiarism checker for content copied from outside sources without attribution.
• Hallucination detector, shown as a second tab next to the AI detector.
• Writing feedback and an AI tutor, including a free grammar check.

Where it works. GPTZero lists a Chrome extension that runs automatic AI detection on Gmail, Google Docs, Google Classroom and social media, along with integrations for Canvas, Zapier and an API. Its pricing page says the API comes with ready-to-use code in 17 languages, including Node.js, Python, C#, Java and PHP.

For schools. GPTZero states it is independently audited and SOC 2 Type II compliant, follows FERPA, GDPR and CCPA, deletes personal data on request, and has completed HECVAT assessments and VPAT accessibility documentation. If your school's IT team has to approve tools, that paperwork matters.

What it costs. You can start for free. The free paste-in checker shows a 10,000-character limit with an "Upgrade" link. The pricing page offers monthly and annual billing, with annual described as "Save 45%". It also sells a Professional Team plan that you can buy without a sales call: at least 2 seats, everything in the Professional plan for each seat, shared team credits, unified billing and seat management, and 500,000 words per member per month. Team plans are card payment only; purchase orders, invoicing and larger teams go through sales. The dollar amounts on the pricing page did not appear in the text we saved, so check GPTZero's pricing page for current prices before you buy.

Accuracy claims. GPTZero's homepage claims 99.9% accuracy. That is the company's own figure, and no AI detector should be treated as proof on its own.

Getsolved.ai: what it is and what it costs

Getsolved.ai is an AI detector and writing tool site run by LESTAS UAB, based in Vilnius, Lithuania. It checks text for patterns from ChatGPT, Claude, Gemini and other models, and focuses on explaining why a passage was flagged rather than only giving a percentage.

What you can do. According to its AI detector page:

• Sentence-level feedback that shows which phrases read as artificial or overly formal.
• A clarity score next to the AI score, with a report on why sections sound awkward.
• Rewrite suggestions for sections with an inconsistent or mechanical tone.
• File uploads in PDF, DOCX, TXT, Google Docs and other formats, so you don't need to copy and paste.
• More than 20 languages, not only English.
• Documents up to 10,000 words per request, with results in under 10 seconds in your browser.

The site also links to a range of other writing tools, including a plagiarism checker, grammar checker, paraphrasing tool, summariser, readability checker, citation checker and an AI humaniser.

Privacy. Getsolved says uploads are processed in a secure environment and are never used to train models or shared with third parties.

What it costs. The AI detector is free with no sign-up required, according to the homepage. The pricing page says all paid plans include an advanced AI detector with sentence-level analysis, grammar checker, AI text improver, fact checker, a plagiarism checker that scans more than 18 billion web pages and private databases, a paraphraser, personal expert review by professional editors, and 24/7 live support. Its FAQ says some plans renew automatically unless cancelled before the renewal date, and that you can cancel at any time in your account settings or through support. No plan prices appeared in the page text we saved, so check the checkout screen and Getsolved's subscription policy before you pay.

Accuracy claims. Getsolved's FAQ claims a 98% accuracy rate and a false-positive rate under 0.2%. As with GPTZero, these are the company's own numbers.

Which one suits you?

You're a teacher checking student work. GPTZero is the closer fit. It plugs into Google Classroom and Canvas, its Chrome extension works inside Google Docs, and its compliance documents (SOC 2 Type II, FERPA, HECVAT, VPAT) are aimed at school IT reviews.

You're a student who wants to prove you wrote your essay. GPTZero's Writing Replay in Google Docs records how a document was written, including copy and pastes. Getsolved does not describe a feature like this.

You want a quick check without an account. Getsolved says its detector is free with no sign-up. GPTZero also lets you paste text for free, up to 10,000 characters.

You check long documents or files. Getsolved accepts uploads in PDF, DOCX, TXT and Google Docs formats and up to 10,000 words per request, which is more than GPTZero's 10,000-character free box.

You work in languages other than English. Getsolved says it analyses writing in more than 20 languages. GPTZero's homepage did not list supported languages in the text we checked.

You're a developer adding detection to your own app. GPTZero offers an API with sample code in 17 languages. We did not see an API mentioned on Getsolved's pages.

You manage a small team. GPTZero's Professional Team plan can be bought online from 2 seats with shared credits and central billing. Getsolved did not describe team plans on the pages we checked.

How we compared them

We read each tool's official homepage and pricing page as saved on our server, then checked them against our own listings. For GPTZero we used gptzero.me and its pricing page. For Getsolved.ai we used its AI detector page and pricing page. All details were checked on 9 November 2026.

Neither pricing page showed plan prices in the text we saved, so we have left prices out rather than guess. Prices and plan features change often, so check each official site before you subscribe. We did not run our own accuracy tests, and the accuracy figures quoted above are the companies' own claims. AI detectors can be wrong, so treat any result as a starting point for a conversation, not a final verdict.
