Sider Review: An AI Assistant on the Right Side of Your Browser — Multi-Model + Text Selection Translation, How Much Can 100 Users Earn?

You're researching something, and you've got twenty tabs open in your browser. You spot a good sentence, select it, copy it, switch to the AI chat window, paste it, and wait for a reply. There's a word in the reply you don't recognize, so you switch back to search. After searching, you realize you can't find the original page anymore.

This routine repeats itself dozens of times a day. Annoying? Absolutely. Sider was built specifically to fix this pain point.

What Exactly Is Sider?

In one sentence: it's an AI sidebar that lives on the right side of your browser. Wherever you go, it follows. No tab switching, no copy-pasting.

It's a US company founded in 2023, with the official site at sider.ai. There are extensions for Chrome, Edge, and Safari, plus apps for iOS, Mac, Android, and Windows.

Core Features, One by One

• Multi-model chat in the sidebar: Pull it out from the right whenever you need it. You can pick GPT, Claude, Gemini, DeepSeek, or Llama.
• Text selection explanation and translation: Select any passage and get results instantly, without leaving the current page.
• One-click summaries for web pages and YouTube videos: Long articles, long videos — click once and get a summary.
• File/PDF/link Q&A: Drop a PDF in and ask questions about its contents directly.
• AI image generation and AI text-to-speech: Generate images right in the sidebar, or have text read aloud.
• Data analysis, audio-to-text transcription, and image OCR: Feed it data to analyze, convert recordings to text, and extract text from images.

Models come in two tiers. The basic tier includes GPT-4o mini, Claude 3.5 Haiku, DeepSeek V3, Gemini 2.0 Flash, and Llama 3.3 70B. The advanced tier includes GPT-4o, Claude 3.5 Sonnet, Gemini 2.0 Pro, Llama 3.1 405B, DeepSeek-R1, o3-mini, and o1. For everyday translation and summarization, the basic tier is plenty; for complex writing or heavy reasoning, switch to the advanced tier.

Pricing: Four Tiers

How Affiliate Commissions Work

It runs through the Trackdesk dashboard. Data verified on 2026-10-12:

• Monthly plans: 10% commission
• Annual plans: 5% commission
• One-time sales: 5% commission
• Cookie duration: 60 days

Let's do the math. Say you bring in 100 users, and they all buy the monthly Unlimited plan at $16.7/month. Your commission per user is $16.7 × 10% = $1.67. With 100 users, that's $167 in monthly commissions. As long as those users keep renewing, that money keeps coming in every month (final numbers depend on actual settlement in the Trackdesk dashboard).

Now let's say 100 users buy the annual Unlimited plan at $200/year. Your commission per user is $200 × 5% = $10. With 100 users, that's a one-time $1,000.

The 60-day cookie window means if a user clicks your link and makes a purchase within two months, it still counts as yours.

Being honest here: Sider is a low-ticket product. 100 paying users gets you a little over a hundred bucks a month — roughly a thousand RMB — which is nowhere near the scale of something like GoHighLevel, where a single customer can bring in tens of dollars per month. It works best as a "passive" income stream — throw it into your AI tool content as a side mention — but it's not worth making your main focus.

Payouts and Compliance: The Straight Talk

As for payout methods and minimum payout thresholds, this time I only verified the commission rates and cookie duration in the Trackdesk dashboard. The payout details weren't verified, so I'd recommend checking the settlement page in your own dashboard before you start promoting.

One compliance note: it's a browser extension, which means it reads the content of your current web page while you work. If you're privacy-conscious, review its permission details before installing. The company is a US entity, so users in China will need to pay with an international credit card.

Six Side-Hustle Angles: What Else Can You Do with Sider?

• Help others break down barriers: Installation takes three minutes — the barrier is too low, no room for done-for-you services. Not a fit.
• Build a CPS directory: Good fit. Tuck it into an "AI browser extensions" roundup page and promote it alongside similar tools to earn referral income.
• Sell courses or training: Some potential. Think scenario-based courses like "Using Sider for Fast Reading of Cross-Border English Materials" — you're selling the method, not the tool.
• Build a product on top: It's just an extension, with minimal room for secondary development. Not a fit.
• Concept arbitrage: It's not publicly traded. Not a fit.
• Affiliate marketing: That's literally what this article is doing. With 10%/5% on a low-ticket product, you're playing a volume game — you need consistent content traffic to make it work.

Who It's For, Who It's Not For

Good fit: People who spend all day in the browser researching, reading papers, or watching videos. Anyone who's tired of constantly switching tabs and wants AI baked into their workflow.

Not a fit: People who already use standalone AI clients and don't mind switching windows. Also those who have browser-extension OCD and refuse to install any add-ons.
