Good for
A quick spelling and grammar pass on a few paragraphs with no account, and a few sentence rewrites a day.
Main limit
The editor showed a 2,000-character cap, one issue in our seeded text sat behind Premium, and paraphrasing showed a 3-sentence counter. We did not open the Premium tile.
Free plan facts↑ Contents
| Account needed | No. Both checks and the paraphrase ran as a guest; we entered no email and created no account. “Sign up” and “Log in” sit in the header |
|---|---|
| Input limit | The counter, which appears once text is in the box, read “Characters 410/2000” and “838/2000”. The empty editor showed no limit |
| Paraphrasing | A “Paraphrasing 0/3” counter. After one applied rewrite it read 1/3. A tooltip says: “Do you need more than three paraphrased sentences a day? Benefit from unlimited paraphrasing and much more with LanguageTool Premium.” |
| Free versus Premium | The page’s FAQ says: “The free version corrects spelling as well as simple punctuation and some style mistakes. Only the Premium version will show you all errors and give you the best possible text.” |
| Language | The selector defaulted to English (US) and lists more than 30 variants. It was a manual pick, not labelled auto-detect |
| Picky Mode | A toggle marked “NEW”, off by default. We left it off |
| Time to result | Not timed. In the automated run, 12 flags appeared right after the paste and the count settled at 15 within about two seconds. The clean text settled in about one to two seconds |
| Popups and captcha | No cookie banner, captcha or sign-up popup appeared at any step, including when we opened every suggestion card |

Planted errors, one by one↑ Contents
Text G is a paragraph we wrote with 13 deliberate errors. This table lists each one, what the free checker marked, the label on its card and the single fix it offered. It also marked a comma after “it,” that we had not planted.
| Planted | Flagged | Card label | Fix shown |
|---|---|---|---|
| “me and my team” | “me and” and “team” | Grammar mistake (both) | Delete “me and”; “team and I” |
| “The interface are” | “are” | Correct the subject-verb agreement | is |
| “their is a lot of features” | “their is” | Use the right word | there are |
| “the setup take” | “take” | Use a different part of speech | takes |
| “Everyone agree” | “agree” | Use a different part of speech | agrees |
| “more faster” | “more” | Fix the comparative or superlative | Delete “more” |
| “faster then the” | “then” | Use the right word | than |
| “We also seen” | “seen” | Change the verb tense | saw |
| “disapointing” | “disapointing” (red) | Correct the spelling error | disappointing |
| “Despite of” | “of” | Fix the preposition | Delete “of” |
| “useing” | “useing” (orange, not red) | Grammar mistake | using |
| “it save” | “save” | Use a different part of speech | saves |
| “alot” | “alot” (red) | Correct the spelling error | a lot |
| Not planted: “keep useing it,” | The comma after “it” | Remove the comma | Delete |
Findings & screenshots↑ Contents
- All 13 planted errors were marked, with one fix each. The sidebar listed 15 free items: 14 cards for our 13 errors (“me and my team” got two) and the unplanted comma. No card offered more than one replacement, and the explanations are short and generic, such as “There might be a mistake here.”
- One more issue sat behind Premium. A tile at the top of the list read “1 more grammar issue — Premium”, and an orange “1” badge sat beside the red “15” at the bottom. We did not open it, so we cannot say what it was.
- The AI-written paragraph passed with nothing marked. Text A, the stock AI paragraph used across this site, came back “Splendid! No errors were found.” That is expected from a grammar checker, but it means a clean result here says nothing about whether text reads as AI-written.
- Labels were not always the obvious ones. “useing” was an orange “Grammar mistake” with the fix “using”, while “disapointing” and “alot” were red spelling errors. “Everyone agree”, “setup take” and “it save” were all labelled “Use a different part of speech”.
- The paraphrase tab worked as a guest. Selecting the first sentence of text A returned five rewrites labelled Simple, Formal or Standard. We applied the first and it replaced the sentence in place. The Simple rewrite dropped “fundamentally” and turned “academic work” into “schoolwork”. That is our reading of one output.

Both inputs, so you can run them elsewhere, and the five paraphrase suggestions for the first sentence of text A.
Last week me and my team tested a new project management app. The interface are clean, and their is a lot of features, but the setup take too long. Everyone agree that the mobile app is more faster then the desktop version. We also seen several bugs when we tried to export a report, which was disapointing. Despite of these problems, we will probably keep useing it, because it save us alot of time every day.
Artificial intelligence has fundamentally transformed the way students approach their academic work. In today's rapidly evolving digital landscape, AI-powered tools offer unprecedented opportunities to enhance learning outcomes and streamline research processes. Furthermore, these technologies enable learners to access personalized feedback, identify knowledge gaps, and develop critical thinking skills more efficiently than ever before. However, it is important to note that the integration of AI in education also presents significant challenges, including concerns about academic integrity and over-reliance on automated assistance. Ultimately, striking the right balance between leveraging AI capabilities and fostering independent thought will be crucial for educators and students alike as they navigate this new era of learning.
1. Simple: How students do their schoolwork has changed a lot because of AI. 2. Formal: Students' academic endeavors have been substantially altered by artificial intelligence. 3. Formal: The method by which students approach their academic work has been fundamentally altered by artificial intelligence. 4. Simple: AI has completely changed how students do their schoolwork. 5. Standard: The way students approach their academic work has been profoundly altered by artificial intelligence.

Method & updates↑ Contents
On Oct 31, 2026 an automated browser opened LanguageTool as a guest with the defaults (English US, Picky Mode off). It pasted text G, opened every suggestion card without applying any, then replaced the box with text A. On text A it used the Paraphrase tab once, on the first sentence, and applied the first suggestion. A first attempt to type text A was garbled by the automated typing; the result reported here is from a re-paste whose join point was verified. Jamie C. checked the records and wrote this page. Full method.
Not tested
- The Premium issue behind the tile, and what the paid version flags that the free one does not
- Picky Mode, and languages other than English (US)
- What happens at 3 of 3 paraphrases, and whether the counter resets daily
- Applying the fixes: we read each card but clicked none, so we do not know how the two “me and my team” fixes combine
- Texts near 2,000 characters, the Word-document check and the browser extensions
- How it compares with other grammar checkers on the same text
- Anything behind an account
