When you’re locked into a page, and something doesn’t quite click, the last thing you want is to grab your phone, open a browser, and lose the thread completely. That’s exactly why Viwoods AiPaper Reader builds a physical AI button into the device — so you can tap for help without ever stepping outside the reading moment.
Press, ask, and carry on: behind that single hardware key, the reader quietly routes your voice or on-page capture to artificial intelligence to answer questions about what you’re seeing right now, turning quick checks into part of your reading flow instead of a distraction from it.
Meet the AI Key: Location and How It Works
Where the AI Key Sits
On the Viwoods AiPaper Reader, the AI Key is a small hardware button on the lower right side of the device. It’s placed where your fingers naturally rest when you hold the reader in one hand, so you can find it by feel and trigger help without shifting your grip or looking away from the page.
What the AI Key Actually Does
The AI Key is your shortcut into two types of assistance: asking a quick question and sending what’s on screen for analysis. Instead of opening another app or digging through menus, you press this single button and the ereader quietly passes your request to AI in the background, while your page stays put. The core idea is simple: one physical key turns “just reading” into an interactive, guided experience.

One-Tap Voice to AI: Ask Questions Without Leaving the Page
How Voice to AI Works on AiPaper Reader
Press and hold the AI Key, speak your question, and release. AiPaper Reader records up to around 60 seconds of speech, converts it to text in the background, and sends it to your chosen AI model, then shows the reply in a dialog box layered over the current page.
What to Ask with Voice
Voice works best for the questions you’d naturally say out loud, such as:
- “Explain this in simpler terms.”
- “What’s the difference between these two ideas?”
- “Summarise this section in a few bullet points.”
- “How would you rewrite this more formally?”
Short, focused prompts tend to get the cleanest answers, so it helps to start with a clear verb like summarise, explain, compare, rewrite, or translate, then point to “this paragraph” or “this part about X.” In that sense, the physical ask ai button becomes a stand-in for the quick margin notes you’d normally jot down, only this time the note talks back.
When Voice to AI Fits Your Reading Flow
Voice really earns its place in all the moments when typing feels clumsy or slow, for example, when you are commuting with one hand on the reader, reading on the sofa, or working through long reports where you’d never bother to tap out a full question on an on-screen keyboard. Instead of breaking posture, opening another device, and risking distraction, you keep your grip, keep your eyes on the text, and talk through what’s confusing you. Over time, those small in-place clarifications add up, and the AI Key shifts from “extra feature” to something that quietly supports every deep reading session you have on the device.

Reading Screenshot to AI: Context-Aware Answers from the Page
What Screenshot to AI Does
Sometimes the problem is not a single sentence but a whole formula, a dense paragraph, or a chart filled with labels, and in those moments, it helps if the device can see exactly what you are looking at instead of guessing from a vague question. On Viwoods AiPaper Reader, you can capture the current screen and send that specific content to artificial intelligence to answer questions, so the reply is tied to the text or visual on the page rather than a generic search. The AI looks at the captured area, recognises the words and layout, and then returns explanations, summaries, translations, or key points that stay rooted in the context you were already reading.
How to Capture and Crop Precisely
When you hit a tricky section, you first take a screenshot so the ereader can work with exactly what you see on the page. After the capture, a small floating window appears on the screen showing the screenshot, along with a cropping frame you can adjust by dragging its corners around the region you care about, for example, a paragraph, a figure with its caption, a table, or a block of code. Once the frame feels right, you confirm, choose the AI Assistant and the command you need, and the system then analyzes that selected area in detail to provide a focused response.
Screenshot Commands That Work Well
Screenshot-based queries are most effective when you offer AI a clear task and focus on a specific area of the page. After you crop, you can use prompts like:
- “Summarise this paragraph in three bullet points.”
- “Explain this formula step by step.”
- “Describe the main trend in this chart.”
- “Translate this section into English and keep technical terms in the original language.”
- “Restate this abstract in plain language for a beginner.”
- “Explain what this code snippet is doing and list the key steps.”
Because each prompt is tied to the cropped region on screen, the answer tends to feel focused and relevant, allowing you to spend your time checking understanding instead of retyping complex content by hand.
Choosing an AI Model: GPT, Gemini, DeepSeek, and More
Built-In Models You Can Switch Between Freely
On Viwoods AiPaper Reader, you have a full lineup of AI models ready to go without extra fees, so every press of the AI button uses the same built-in toolkit instead of separate subscriptions. In the model list, you will find GPT-5, GPT-4o, GPT-4o-mini, Gemini-2.5-flash, Gemini-2.5-pro, DeepSeek-R1, and DeepSeek-V3. With a few taps, you choose which type of artificial intelligence to answer questions about the page you want to use, and the reader keeps everything else simple, so you stay focused on reading instead of on settings or accounts.
Pick a Model That Matches the Job in Front of You
A practical way to choose is to link each model to the kind of help you need, so lighter options like GPT-4o-mini or Gemini-2.5-flash are ideal for quick definitions and short clarifications, while GPT-5, Gemini-2.5-pro, DeepSeek-R1, and DeepSeek-V3 feel better when you want careful reasoning, longer summaries, or step-by-step explanations of dense material. Over time, you will probably settle on one favourite for everyday reading and a second model you call on when you want a deeper answer, which turns the Viwoods AI button into a flexible shortcut that can behave like a fast dictionary in one moment and a patient tutor in the next.
Working with AI Dialogs While You Read
When a reply arrives, it appears in an AI dialog layered on top of the page. You can move this dialog to a different part of the screen and resize it, making a long explanation larger when you want to read it carefully or keeping a short answer small and tucked to the side. This way, the lines you are checking stay visible, and the dialog sits wherever it feels least distracting. Pressing the AI button adds a small helper window over your book or document rather than taking you away from it, so the page remains the focus.
FAQ: Using the AI Button on Viwoods AiPaper Reader
Q1: Do I pay extra to use the AI button?
No. The built-in models, including GPT-5, GPT-4o, GPT-4o-mini, Gemini-2.5-flash, Gemini-2.5-pro, DeepSeek-R1, and DeepSeek-V3, are available to use through the AI button without additional fees.
Q2: How long can my voice question be?
You can hold the AI Key and speak for up to about 60 seconds in a single recording. Short, focused questions tend to get clearer answers, so it often works better to break a big topic into several smaller prompts.
Q3: Does using the AI Key change my original book or document?
No. AI replies appear in a dialog on top of your current page, while the underlying e-book, paper, or file remains unchanged, and the answer sits in a separate layer that you can move, resize, or close whenever you like.
Q4: What if the AI dialog covers the part I am trying to read?
You can drag the dialog to another spot on the screen and resize it so it sits out of the way. That way, the lines you are checking remain visible and the AI response stays handy without blocking the text.
Q5: Can I choose which AI model answers my question?
Yes. You can select the model in the relevant settings or AI options before sending a query and switch when your task changes, for example, using a lighter model for quick checks and a more advanced one when you want detailed reasoning.
Conclusion: Make the AI Key Part of Your Reading Habit
The physical Viwoods AI button is there for the instant you think, “I don’t quite get this,” so instead of grabbing another device and losing momentum, you ask from the page and keep reading. One press brings in artificial intelligence to answer questions about the line, chart, or paragraph in front of you, with the reply displayed in a small dialog while the text stays in place.
Start small: use the AI Key to summarise a section, unpack one tricky formula, or translate the occasional paragraph. Once it becomes a habit, AiPaper Reader feels more like a quiet reading partner you can tap whenever you need a clearer view.
