Compare vs Auto vs Image Studio vs Video Studio: when to use which Kryotta tool

I opened the wrong Kryotta tool for three days straight before I figured out the map

I sell candles. Soy wax, hand-poured, scents named after national parks. We do about $8,000 a month through Shopify, mostly repeat customers who found us on Instagram or bought a sampler at a craft fair. I handle everything: the pour, the labels, the email list, the TikTok account I keep promising myself I'll post to more often.

Last month I signed up for Kryotta because I kept hearing other Shopify sellers talk about it in a Facebook group. The pitch made sense—multiple AI models in one place, image tools, video tools, something called Auto that picks the best model for you. I thought I'd save time. Instead, I spent three days clicking the wrong button, waiting for Compare to finish running four models when all I needed was a single email subject line, and once accidentally routing a product photo request to a text model because I didn't realise Image Studio was a separate thing.

I'm not especially slow. The problem is that Kryotta has four main tools—Compare, Auto, Image Studio, Video Studio—and the UI doesn't tell you which one to use when. So I wrote this down for myself, then figured it might help someone else who's staring at the dashboard at 11 p.m. wondering why their TikTok ad is taking six minutes to render.

Compare: when you need to see four answers side by side

Compare runs the same prompt through four models at once—Claude, Gemini, Llama, DeepSeek, whatever you pick—and shows you the results in a grid. It's slower and costs more than Auto (you're paying for four models instead of one), but it's the right tool when the output really matters and you're not sure which model will get it right.

I use Compare for email campaigns. If I'm writing a Black Friday subject line or the opening paragraph of a new-customer welcome sequence, I'll feed the same brief into Claude Sonnet 4.5, Gemini Flash, DeepSeek V3, and Mistral Large. I read all four, pick the one that sounds like me, then edit from there. It takes maybe three minutes total, and I only do it once per campaign, so the extra cost—maybe 15 cents for a typical email prompt—doesn't bother me.

Compare is also good for ad copy when you're testing angles. I ran a Facebook ad last month with three different headlines. I generated all three in Compare, picked the two that felt most different, then ran them as separate ad sets. One outperformed the other by 40 per cent. I have no idea if I would've written that headline myself.

What Compare is bad for: anything repetitive. If you need to write twenty product descriptions or reply to a dozen customer emails, don't run Compare twenty times. You'll spend $3 and twenty minutes when Auto would've cost you 30 cents and three minutes.

Auto: when you just need one good answer, fast

Auto routing means Kryotta picks the model for you based on your prompt. You type the request, hit send, and it decides whether to use Claude, Gemini, DeepSeek, or something cheaper like GPT-OSS 20B. The idea is that simple prompts get routed to fast, cheap models, and complex prompts get routed to the expensive ones.

I use Auto for everything I do more than twice. Product descriptions, Instagram captions, customer service replies, blog post outlines, SMS campaign drafts. I don't care which model writes it as long as the output is good and I'm not waiting. Auto usually picks Gemini Flash or DeepSeek V3 for my stuff, sometimes Claude Haiku if the prompt is short. I've never had it pick a model that gave me nonsense.

The cost difference is real. Last week I wrote fifteen product descriptions in Auto. Total cost: $0.42. If I'd run those same prompts through Compare using four models each time, I'd have spent about $2.50. That's not bankrupting me, but it's six times more for no benefit—I'm not going to read sixty product descriptions and pick the best four.

Auto is also faster. Compare takes 15–30 seconds because it's waiting for four models to finish. Auto usually responds in under ten seconds. When I'm trying to get five things done before I start pouring candles at 9 a.m., that difference matters.

Image Studio: when you need product photos and you don't own a lightbox

Image Studio uses Stable Image Core and SD 3.5 Large to generate product images. You describe what you want—"soy candle in amber glass jar on a wooden table with morning light"—and it renders a photo. You can also upload a reference image and ask it to match the style or swap out the background.

I use Image Studio when I launch a new scent and I don't have time to stage a photo shoot. I'll describe the candle, the surface, the lighting, maybe mention the colour palette, and generate four or five options. I pick the one that looks most like my brand, run it through the editor to tweak the brightness or crop it square for Instagram, and I'm done. Total time: maybe ten minutes. Total cost: about 25 cents per image.

The results aren't perfect. Sometimes the jar looks slightly melted or the wick is in the wrong place. But for Instagram stories, email headers, or a quick product tile on Shopify, they're good enough. I still shoot real photos for the main product page, but Image Studio covers everything else.

One thing to know: Image Studio is not fast. A single image takes 20–40 seconds to generate, depending on which Stability model you pick. If you need ten images, you're waiting six minutes. That's fine if you're batching work on a Sunday afternoon. It's annoying if you're trying to post to Instagram in the next five minutes.

Video Studio: when you need TikTok ads and you can't afford a videographer

Video Studio uses Luma Ray 2 and Nova Reel to generate short videos from text prompts. You describe the scene—"hand pouring wax into a candle jar, close-up, warm lighting, 5 seconds"—and it renders a clip. You can also upload a still image and ask it to animate part of it, like steam rising from a candle or a hand reaching into frame.

I've used Video Studio exactly twice. Once to make a 6-second TikTok ad showing a candle being lit in slow motion. Once to animate a product photo for an Instagram Reel. Both times it worked, but both times I spent twenty minutes tweaking the prompt because the first result looked like a screen saver from 2003.

Video Studio is the most expensive tool. A single 5-second clip costs about $1.50 if you use Luma Ray 2, closer to $0.80 if you use Nova Reel. That adds up fast if you're testing three different ad concepts. But if the alternative is paying a freelance videographer $200 for a day shoot, the math works.

The quality is... fine. It's not going to win a Webby. But for TikTok ads or Instagram stories, where people are scrolling fast and the bar for production value is "better than a static image," it does the job. I got 3,200 views on the candle-lighting video and twelve sales I can trace back to it, so the $1.50 was worth it.

Here's the table I wish I'd seen on day one

The costs are estimates based on my own usage. Your mileage will vary depending on prompt length, model choice, and how many times you regenerate.

My actual workflow: I use all four, but not equally

Monday mornings I open Compare and write the week's email subject lines. I generate four options, pick one, save the others in a doc for later. That's the only time I use Compare all week.

The rest of the week is Auto. Product descriptions, Instagram captions, replies to Etsy messages, the occasional blog post outline. I have a few prompt templates saved—"Write an Instagram caption for [product] that mentions [scent notes] and ends with a question"—and I just fill in the blanks. Auto picks the model, I get the output in ten seconds, I move on.

I use Image Studio maybe twice a month, usually when I'm launching a new scent or I need a seasonal graphic for the email header. I'll generate a batch of images on Sunday afternoon, pick the best ones, edit them in Canva, and schedule them for the month.

I use Video Studio the least. Maybe once a month if I'm running a paid ad campaign and I want to test a video asset. It's too slow and too expensive for casual use, but when I need it, nothing else will do the job.

Questions people ask

Should I use Compare or Auto for customer service emails?
Auto, unless you're writing a template you'll reuse a hundred times. Compare is overkill for one-off replies, and you'll spend more time reading four versions than you'd spend just editing the one Auto gives you.

Can I use Image Studio for my main Shopify product photos?
You can, but I wouldn't. The images are good enough for secondary use—email headers, Instagram stories, blog thumbnails—but they're not quite sharp enough for the hero image on a product page. Shoot those yourself or hire someone.

Which tool is cheapest?
Auto, by a lot. Video Studio is the most expensive. If you're on a tight budget, use Auto for everything except the handful of tasks where you genuinely need images or video.

Do I need to learn all four tools at once?
No. Start with Auto. Once you're comfortable, add Compare for the high-stakes stuff like email campaigns. Image Studio and Video Studio can wait until you actually need a product photo or a TikTok ad.

I still click the wrong tool sometimes. Last week I opened Video Studio when I meant to open Image Studio, then sat there confused for thirty seconds wondering why the interface looked different. But now I at least know which tool I should be using, which means I'm wasting less time and less money.
