The AI text correction function is a new feature added to the Jieshuo screen reader in version 20260330. It attempts to detect mistakes in text and correct them. This correction relies on an online AI service provided by Vivo, although the exact model used is unknown.
How to use the function
The AI text correction function is located in the Recognition menu, which is part of the Functions menu. By default, the Functions menu can be accessed by swiping up then right with one finger. The Recognition menu can also be reached from the Main menu. The function’s name is still in Chinese and appears as the last item in the list.
To use the function, focus on the text you want to correct and then activate the function. Once the AI response is ready, a new screen appears showing an edit box with the corrected text, along with OK and Cancel buttons. It is possible to make edits to the suggested text. Pressing OK pastes the text into the focused edit box. If no edit box is focused, Jieshuo will attempt to paste it into the edit box it detects. Pasting replaces any existing text with the AI response.
If Jieshuo cannot insert the text into an edit box, pressing OK copies the text to the clipboard instead. Pressing Cancel closes the screen without making any changes. The function can also be used on any focused text, even if it is not an edit box.
Evaluation and Text Samples
Overall, the service performs fairly well in detecting mistakes and fixing them. During my tests, it handled spelling errors and most grammatical mistakes very effectively. It also did a good job correcting structural issues. The AI was able to detect wrong verb tenses, adverb misuse, subject-verb agreement issues, proper verb usage, and more. Two samples of these corrections will be shared at the end of this post.
One positive observation is that the service does not seem to have a tendency to over-correct or paraphrase—a tendency sometimes found in AI corrections. Word changes during my tests were kept to a minimum.
Despite its solid performance, the feature is not flawless, which is expected given the nature of AI. It is always important to remember that with AI services, there is always a chance of quirks and oddities
When I tested the word borrow instead of lend for money and also misspelled borrow, the service identified from the context that lend should be used, and it replaced it correctly in one instance but failed to do so in another, correcting only the spelling.
In another example, it used the perfect form for an event that happened in the past. Instead of I went after yesterday when the subject was going to a store, it used have gone. The inconsistency continues with the phrase couldn’t be able that I used several times. While the service handled it correctly most of the time, in one instance it considered the repetition of be able as a mistake and removed with without removing the incorrect couldn’t be able.
It is worth mentioning, though, that such inconsistencies are not unique to this AI service. They are observed in other AI services as well, including more advanced and popular ones, across a variety of topics.
In one of the samples I will share, there is a mixture of present and past tenses. The correct usage should be inferred from the context. The service used the past tense for the last part of the text when I was talking about long check-in lines and being worried about missing the flight. From the understanding of the text, this is a general worry, which would make the present tense more suitable. However, since the previous part was about calling the doctor to ask about headaches during flights—a past event—the service applied the past tense to the last part as well, despite correctly using the tense for a comment earlier about children’s noise during flights.
While it would be unfair to say the service was entirely wrong, this example signals that every AI-corrected text must be reviewed before use.
One more thing to keep in mind is that if you use the function on similar text twice, the service might detect and fix an issue in one response but not in the other—and the opposite can also happen.
During my tests, the AI provided only the correction most of the time. However, in a few cases, it added additional text. For example, it sometimes included explanations or sentences like “The correction of your sentence is…”, or it indicated that the sentence had many mistakes. All of these comments and explanations are in Chinese. It is well known that many English TTS engines cannot detect Chinese text, so when reading the text quickly, the user might not notice the Chinese additions. As a result, they might press OK to use the correction, which would paste the entire response.
In conclusion, the service performed well, especially in fixing more common mistakes, despite occasional issues that are not enough to give it a poor rating. Additionally, as I always note with AI-based functions and features, any change or development in the AI service can improve or worsen the results you get from the feature.

He suggested that I try to get some sleep while traveling, but how could I sleep when there are many children playing and shouting loudly? What makes matters worse is that when you try to ask their parents to calm them, they don't take your complaints seriously. Also, the airport is very crowded and the check-in lines are very long, so I was worried I would miss my flight.

My phone's battery was draining quickly, so I decided to go to a nearby phone shop to get a new phone. There, I met one of my friends who helped me decide what phone to buy. He advised me to get a high-end Samsung phone because it works well and has many good features. I told him that I cannot afford to purchase it because I don't have enough money, so he offered to lend me some. When the shop owner saw my old phone, he asked me if I wanted to sell it to him.
