Over 10,000+ office workers and content creators in Vietnam are wasting an average of 5 hours per week just switching between browser tabs and different AI tools (according to a 2026 digital user behavior survey). Having to purchase ChatGPT Plus, Claude Pro, or Gemini Advanced separately costs you over 1,500,000đ per month. The most optimal solution today is to buy a cheap Sider Plus account – an All-in-One extension integrating over 30 of the most powerful AI models directly into your browser sidebar.
The free Sider version only provides a very small amount of daily credits, which is completely insufficient for handling in-depth work tasks. When you need to analyze a 50-page financial report via ChatPDF or translate an important document, running out of credits midway will severely interrupt your workflow.
Upgrading to Sider Plus gives you a huge usage limit, allowing access to the most advanced AI models of 2026 such as GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, and especially DeepSeek V3. Having a powerful tool right in your browser helps speed up work processing by 3 times (according to Sider's internal performance report 2026).
In today's market, many providers offer Sider accounts as "group buys" at extremely low prices. However, data from cybersecurity experts in 2026 indicates that 85% of users with shared accounts face a high risk of personal data leakage. When you upload internal company documents via ChatPDF or record meetings via REC Notes on a shared account, dozens of other strangers can easily read this confidential information.
At Lucifer Tech, we distribute Personal account (upgraded on your own email). This is the customer's direct Gmail/email account. Customers use their own account, which is upgraded to the Premium plan. The absolute advantage of this account type is full control, 100% high security, and no one can access your chat history or documents.
To help customers better understand the account types on the market, we always clarify two concepts:
Seamlessly switch between DeepSeek V3 (specialized in code/logic), Claude 3.5 Sonnet (specialized in writing), GPT-4o, and Gemini 1.5 Pro with just one click, no need to open multiple tabs.
Automatically record, transcribe, and summarize online meetings. Summarize 60-minute YouTube videos into key points with timestamps in just 5 seconds.

Good browser AI assistant. Bought from Lucifer Tech, quick activation, reliable warranty. Recommend!
Sider AI sidebar is convenient, used directly in the browser. The Plus plan has many models. Reasonable price!
I use Sider AI for daily tasks. Summarize articles, translate, chat — all in the sidebar.
Instead of paying the expensive listed prices on international apps (incurring additional foreign exchange conversion fees and taxes), buying a cheap Sider Plus account at Lucifer Tech helps you save up to 45% of the actual cost. We offer two flexible upgrade plans, tailored to specific usage needs in 2026:
2026 marks the explosion of new-generation AI models, and Sider AI is a pioneering platform that integrates all of them into a single interface. You no longer need to open 5 different browser tabs to compare answers from various AIs.
REC Notes (AI Note Taker) is one of Sider's most valuable features in 2026. This tool automatically records, transcribes, and summarizes online meetings on Google Meet, Zoom, or Microsoft Teams. According to statistics from 5,000 Sider users, REC Notes helps save an average of 2 hours per day on meeting minute-taking.
In parallel, ChatPDF has received a major update, making document collaboration smarter. Simply upload a 100-page PDF file, and Sider AI will comprehend the entire content in less than 10 seconds. You can ask direct questions, request specific data extraction, or summarize key arguments with page-level accuracy.
Do you have a 60-minute YouTube video you need to watch for research? Sider's AI Video Shortener will solve this problem. Just paste the link, and the system will generate a detailed summary with important timestamps. You can grasp the entire core content without having to watch the whole video.
Notably, the Deep Research Agent feature (just launched in 2026) transforms Sider into a true research assistant. When you enter a complex topic, the AI will automatically browse dozens of reputable websites, synthesize information, eliminate junk data, and present you with a complete report accompanied by clear source citations.
Sider AI supports translation for over 50 languages with quality far surpassing traditional translation tools. By leveraging the power of GPT-4o or Claude 3.5, Sider doesn't translate "word-by-word" but analyzes the entire context, tone, and cultural nuances. This is especially useful for professionals working in multinational environments, helping emails and communication documents always maintain professionalism and naturalness.
Owning this super AI assistant has never been easier. At Lucifer Tech, the process for buying a cheap Sider Plus account is optimized to provide the fastest and most transparent experience for customers:
Don't let repetitive manual tasks erode your creativity and valuable time. Investing in a Sider Plus Personal account today is the smartest move to upgrade your work efficiency in the AI era of 2026. With prices starting from just 150,000đ/month, you'll have the power of over 30 of the world's most outstanding artificial intelligences at your fingertips.
AI research assistant that automatically gathers, analyzes, and synthesizes data from dozens of reputable internet sources to generate comprehensive reports.
Comprehend, extract information, and summarize hundreds of pages of PDF reports with absolute accuracy, saving hours of manual document reading.
Supports translation for over 50 languages. Utilizes GPT-4o or Claude to preserve writing style, idioms, and cultural context, far surpassing Google Translate.
A Personal account (upgraded on your own email) is upgraded directly on your personal email, ensuring 100% privacy. No one can view your chat history or ChatPDF documents. In contrast, a shared (group buy) account requires you to share your workspace with many strangers, leading to a very high risk of internal data leakage and frequent credit limit errors due to too many simultaneous users.
The 150K plan (original price 270K) provides abundant basic credits, suitable for general office and study needs (translation, email writing, short summaries). The 600K plan (original price 1,050K) unlocks a massive credit limit for the most advanced AI models (GPT-4o, Claude 3.5, DeepSeek V3), suitable for programmers and researchers who need to process large data, use Deep Research Agent, and ChatPDF continuously.
As of 2026, Sider AI Plus integrates over 30 world-leading models. The most prominent models include: DeepSeek V3, Claude 3.5 Sonnet, Claude 3.5 Haiku, GPT-4o, GPT-4o mini, Gemini 1.5 Pro, Gemini 1.5 Flash, and Llama 3.1 (70B/405B).
Absolutely. Sider AI supports cross-platform synchronization. You just need to log in to your upgraded Personal account (upgraded on your own email) on the computer extension (Chrome/Edge/Safari) and the Sider app on your phone (iOS/Android) to use it seamlessly anytime, anywhere.
ChatPDF allows you to upload long PDF files, and the AI will automatically comprehend and answer any questions related to the document's content in seconds. REC Notes is a meeting note assistant, automatically recording, transcribing speech to text, and summarizing key points for meetings on Google Meet, Zoom, or YouTube videos.
Lucifer Tech commits to a full 1-month warranty for all Sider Plus accounts sold. If there are any technical issues related to the plan (loss of Premium, model recognition error), our 24/7 support team will resolve and restore your benefits immediately.
It's excellent. Thanks to the integration of the most advanced large language models (LLMs) like GPT-4o and Claude 3.5 Sonnet, Sider AI deeply understands Vietnamese grammar, writing style, and slang. This tool translates smoothly, naturally, and writes Vietnamese content with far greater accuracy than traditional translation tools.
Step 4: Install the Sider extension/app
On your computer: Open Chrome, Edge, or Safari browser. Go to the Extension Store, search for "Sider AI," and click "Add to browser."
On your phone: Download the Sider app from the App Store (iOS) or Google Play (Android).
Step 5: Log in and start experiencing
Open the Sider extension in your browser sidebar. Select "Sign in" and accurately enter the email address you provided in Step 2. The system will automatically recognize the Plus plan. Now, you can freely switch between the 2026 AI models (DeepSeek V3, Claude 3.5, GPT-4o), use ChatPDF, REC Notes, and enjoy superior work speed.
