Great value for AI tools

I was looking for a good deal on an AI assistant and stumbled upon Sider. I've tried a few others like Merlin AI and Perplexity, but Sider really stood out with its included models. It supports GPT-4, Claude, and even Gemini, which is fantastic for the price. I especially like the Sider Chrome Extension for quick access while browsing. I managed to grab an annual subscription when they had a percentage-based discount, making it about 30% off. Definitely felt worth the investment for all those AI models in one spot. 👍

OCR Tool works great!

I was checking out the difference between Sider free and premium, mostly because I needed a good OCR Tool. The free version gave me a taste, but the premium, which automatically applied a 27% discount for the annual plan, really delivered. It extracted text from a complex PDF in seconds.

So close to perfect!

Anyone else using Sider on multiple browsers? This is seriously fantastic for Group Chat AI, and the premium plan is worth every penny! I just wish it had a few more direct discount codes instead of just referral links. Still, totally recommending it to everyone!

pretty good, but still room to grow

hey, anyone else use sider? i grabbed the pro plan during a sale, and it's been super handy for translations and stuff. the AI translator is solid, and i like having access to different models like gpt-4 and claude, but i wish they'd add perplexity or something similar for better research summaries. it's a good value for about 80 bucks annually.

Sider's Grok integration is cool, but a bit pricey

i was checking out how to cancel my sider subscription after trying the grok integration. it's actually pretty powerful, really helpful for summarizing long articles and answering questions quickly. i found the ai sidebar super useful for brainstorming too. my main gripe is that while referral links offer some credit, getting a straight up percentage discount felt harder to find for monthly plans. it seems like the best deals are usually for the annual subscriptions. overall, it's a solid tool, but the pricing could be a little more flexible for short-term users.

finally a real mobile AI tool

grabbed sider last week, mainly for the claude 3.5 access it offers. i was wondering if it worked on mobile and yup, there's an ios app! honestly, it's super handy for quick questions on the go. way better than juggling browser tabs like i used to with perplexity. easy 5 stars.

still my go-to for AI tools

i've tried a few of these AI extensions, like Merlin AI and Harpa AI, but i always come back to Sider. their Writing Assistant is just so consistent, i use it almost daily for work. usually, i'm on the hunt for a good referral link to get some extra credit, which they're pretty good about offering. the automatic discounts for annual subs are nice too. it'd be perfect if they had a few more options for summarization, but it's still top-notch.

Really useful for YouTube

Better than Perplexity for summarizing YouTube videos. Sider makes it super easy to get the gist of long content. Wish it worked on all my browsers without separate installs, but overall very good.

Hey, wondering if anyone knows if Sider still offers a student discount? Trying to save some cash if I can.

Yeah, I think they do! Check their site, usually it's a specific page for students.

If I get the yearly subscription, is it actually cheaper? Or is it just like a small savings?

T Todd G. 2 months ago
Oh yeah, it's definitely cheaper. I saved like 20-30% compared to paying monthly for the same plan. Always go annual if you can.

B Ben 2 months ago
Yep, it's a noticeable discount. They pretty much always push the annual plans because of it.

Is it worth upgrading to the Pro plan from Premium? Like, what's the real difference in daily usage for someone who uses it a lot for research?

A Andre Silva 1 month ago
Pro gives you more advanced models and higher query limits, I found it super useful when I was doing a big report. Premium hits limits faster if you're heavy user.

R Rachel Beaumont 1 month ago
Depends on your usage. If you're constantly hitting the query cap on Premium, Pro is a no-brainer. Otherwise, Premium is usually fine.

How does Sider compare to Perplexity for deep research? I'm trying to decide between them for academic stuff.

A Alex 2 months ago
Sider integrates better directly into your browser for summarization as you browse, which is a huge time saver. Perplexity is more for direct question answering.

P Priya C. 2 months ago
I use both, but Sider's PDF summarizer and the ability to use GPT-4o while reading articles makes it more seamless for research than Perplexity, imo.

I saw something about free credits. How do you get those? Is it like a referral thing or something?

R Rachel 1 month ago
Mostly referral links or invitation codes from other users. That's how I got some when I first signed up.

D Derek 1 month ago
Yeah, if someone refers you, or if you refer someone, you both get credits. Keep an eye out for those codes.
