Customer Reviews
Reliable AI tool
This is my third year with Sider; I always go for the annual Sider Pro Plan. I started with it for the Web Page Summarizer and the AI Chatbot, and they've been consistently good. This time, I'm using the GPT-4o access a lot more, and it's just as reliable as it was last year. I've tried other tools like Monica AI, but I always come back to Sider because it just works without fuss. The integration with my browser is seamless, and I haven't had any issues with billing or service interruptions. It's predictable, and that's what I value most.
Solid features, minor hiccup
I signed up for the Sider Premium Plan to use the AI Chatbot and the Smart Context Menu. The overall shopping experience was fine; I found the annual plan discount helpful. The AI Chatbot is generally very useful for drafting emails and quick research. I particularly like the Smart Context Menu for summarizing selected text. The only minor negative was that the Edge Extension sometimes felt a bit slower to load than the Chrome version, though it always worked in the end. Delivery was instant, as expected for a subscription. Customer service wasn't needed, so that's a positive. Good value for what it offers, just hoping for a bit more speed on Edge.
Good for quick summaries
Got the Sider Pro Plan. Needed the YouTube Summarizer. It works. Saves time. Setup was fast. No problems with payment. It does what it says. Worth it for me.
Easy to use, works well
I just needed something to help with writing for school, so I got the Sider Premium Plan. The Writing Assistant is pretty handy, it catches a lot of my mistakes. I also use the YouTube Summarizer a lot for lectures, which is a lifesaver. It was super easy to get set up on my Mac. Everything just works, no complicated stuff. Happy with it.
Decent tool, some quirks
I purchased the Sider Premium Plan for a year, mainly for the GPT-4o access and the Deep Research Agent feature. Ordering was straightforward on their website, no issues there. Delivery, or rather activation, was instant, which was good. The AI Chatbot is quite responsive for quick questions, and the Web Page Summarizer works well most of the time, cutting down on reading. I found the Deep Research Agent a bit hit or miss; sometimes it pulled great info, other times it felt like just a rehash of search results. Usability with the Chrome Extension is pretty smooth; it integrates without being too intrusive. Customer support, I haven't really needed to use, so can't comment there. Overall, it's a solid tool for productivity, but not every feature is equally polished.
Sider Community Discussion
Share tips, ask questions & help fellow shoppers save more
Is there a student discount for Sider? My university email address works for other software.
How does Sider stack up against Perplexity? I use Perplexity a lot for research but the sidebar thing sounds useful.
can you actually sum up youtube videos with this? would be a game changer for lectures.
Are there ever actual coupon codes for Sider plans, like a percentage off? Or is it just those referral things?
Thinking of getting Sider but I mostly use Safari. Does it actually work well there or is it just for Chrome?
Does Sider actually use GPT-4o or is that just marketing? Some tools say they do but then it's an older model.
