Top 5 Best Undetectable AI 6 Months Free Content Detectors
Start with offers that keep the gate open for six full calendar months. Watch for yearly plans that hide a deep cut on the first bill. Pick the deal that stretches every scanned word to the lowest possible price.

1. Undetectable AI
In Undetectable AI, the banner reads “Pay once, protect twice.” You send sixty United States dollars for a yearly pass and receive twelve months of cover, so the first half of the year feels free. Each cycle grants ten thousand detection words, enough for weekly blog posts or a student project. A traffic-light bar marks risky sentences, and the score updates in real time as you type. You can drag and drop chunks of text or load a whole DOCX file, and the cloud engine answers within seconds. Because the scan runs online, no download is needed, which helps writers on school laptops that block installs.
Users also find a rewrite tab that keeps the feel of the text while lowering the AI score. A neat progress wheel shows how many words remain in the month, so surprises stay away. Solo creators who need even more room can jump to the Pro tier, yet most casual writers never hit the ceiling. Another benefit is the fast support chat that helps new users understand warning colors, and many questions receive answers in under five minutes during common work hours. All these points make this tool the best AI detector deal for fresh users who want strong value.
Pros:
- Combines eight detector scores.
- Humanizer rewrites flagged text.
- Color map spots risky lines.
- API automates bulk scans.
Cons:
- Rewrites sometimes add errors.
- Monthly cap: ten thousand words.
- Advanced tests still catch text.
- Pay full year upfront.
2. Polygraf AI
Polygraf AI stands out because it asks for zero money up front. You open an account with an email only. For six straight months, the system loads two thousand words into your balance each month. Once the sixth block ends, the site pauses scans and invites you to pay. The true gift here is freedom, since you may walk away with no charge if the service does not fit you. The daily interface stays simple: one box for text, one big Scan button, and a score that shows up in large font so younger students can read it easily.
Many users add the Chrome extension to check drafts inside Google Docs with one tap. The tool labels text as Safe, Mixed, or High-AI, and it can suggest edits on the spot. Teachers often start on the free path, then upgrade when class projects pile up. For power users, an export-to-PDF button makes sharing results with clients smooth, and these small touches raise comfort and trust. This path is the longest six-month AI detector trial you can gain without a credit card, perfect for light or seasonal work.

DetectGPT shows its math in bold type: “Yearly – six months free.” You pay fifty-four dollars today for the Essential plan and in return gain twelve months of scanning. Each month carries fifty thousand words, which suits large content teams, newsrooms, or busy marketing squads. A side-by-side window highlights every risky phrase and offers word swaps until the score sinks below a safe line. If you run a content farm, this high word budget lets editors scan every article before it leaves the door, cutting risk.
One dashboard lists each team member and tracks how fast they burn through the shared pool. Export options include CSV for data sheets and HTML diff for quick web view. Developers also gain an API key that plugs into custom dashboards, letting you build alerts when a score crosses a set line. Because the price halves the normal yearly cost, many firms count this as the best yearly discount content filter for long runs and heavy traffic.
Pros:
- Fifty thousand words each month.
- Side-by-side PDF exports.
- Humanizer and plagiarism combo.
- API and batch file scans.
Cons:
- Pay yearly upfront for discount.
- Essential tier single user.
- Browser extension privacy concerns.

Bypass AI, also known as StealthWriter, doubles as both guard and fixer.

Journalists enjoy the link scan, since they can paste a news URL and test whether a press release came from human hands or a smart bot.
After the grade shows, a strength slider lets you choose how bold the rewrite should be, from light touch to full overhaul. Users who repair large archives of old blog posts rely on this dial to keep voice steady. A bulk mode lets you drop ten URLs at once, saving hours during archive sweeps, and reports arrive in tidy tables that sort by highest risk first. Together, the detect screen and the rewrite engine deliver a long trial AI content checker that smooths bulk updates and stops AI flags.
