The Tribest Slowstar AI juicer is a vertical single-auger masticating juicer that automatically adjusts its speed between 32 and 60 RPM based on what you’re feeding it, making it the most intelligent juicer currently available. It’s made by Tribest, features a 150W motor, and costs around $399.95 in the US, though discounts bring it down to $349.95 at select retailers. The machine is available globally, with UK pricing at £438. What makes this juicer stand out is its AI mode—a screenless technology that senses ingredient resistance and optimizes extraction speed in real time, a feature that separates it from traditional juicers with preset buttons.
Key Takeaways
- The Tribest Slowstar AI juicer uses variable AI speed (32–60 RPM) that auto-adjusts for different ingredients, making it faster than competing slow juicers.
- Vertical hopper design eliminates constant pushing; ingredients feed naturally into the machine.
- Makes juice, sorbet, nut butters, and purees via interchangeable attachments.
- Main drawback: some pulp remains in the juice, requiring tolerance for a slightly thicker consistency.
- UK pricing at £438 with free delivery; US discounts available, with code DJX offering $180 off until April 11, 2026.
Why the AI Speed Control Actually Matters
Most juicers run at a single fixed speed. The Tribest Slowstar AI juicer breaks that mold by using variable speed technology that detects what’s in the hopper and adjusts on the fly. Feed it leafy greens, and it slows down to 32 RPM for gentler extraction. Add harder fruits, and it ramps up to 60 RPM for faster processing. This isn’t just a convenience—it’s measurably faster than older Slowstar models locked at 47 RPM, and noticeably quicker than the Kuvings Auto8, which the reviewer found sluggish by comparison. The touch screen interface makes selecting between eight preset speeds or AI mode effortless, something the reviewer found surprisingly convenient despite initially skeptical about a screen on a juicer.
The speed flexibility also means less babysitting. With traditional juicers, you’re constantly pushing produce down, waiting for it to process, and hoping you haven’t jammed the machine. The vertical hopper design here eliminates that friction—ingredients drop naturally into the auger without requiring constant pressure. This is a genuine quality-of-life improvement that shows in the user experience.
Sorbet and Beyond: Versatility That Justifies the Price
The Tribest Slowstar AI juicer isn’t just a juicer. It also makes sorbet, nut butters, and purees via interchangeable attachments. On sorbet specifically, it outperforms blenders like the Tribest Backspin, producing a far more consistent frozen texture. This versatility matters because a dedicated sorbet maker like the Ninja Creami costs around $229 but does only sorbet, while the Slowstar AI does sorbet and juice for roughly twice the price—a better value proposition for households that want both.
The sorbet capability is worth highlighting because it’s genuinely useful. Making sorbet from frozen fruit in a regular blender produces an icy, uneven texture. The Slowstar AI’s auger-based approach yields smooth, creamy results that rival dedicated machines. If you’re serious about frozen desserts or want a single machine that handles multiple functions, this is a real advantage over single-purpose appliances.
The Pulp Problem That Won’t Go Away
Here’s the catch: the Tribest Slowstar AI juicer leaves a tiny bit of pulp in the juice. This isn’t a catastrophic flaw, but it’s the machine’s primary weakness, and it’s worth understanding before you buy. If you’re accustomed to crystal-clear, pulp-free juice from a centrifugal juicer, you’ll notice the difference. If you prefer thicker, more nutrient-dense juice, you won’t mind at all. The reviewer was honest about this trade-off: the machine is exceptional in almost every other way, but pulp tolerance is a personal preference, not a defect.
For leafy greens and soft fruits, the AI mode handles the job well. For harder produce like ginger, the variable speed helps, but some pulp still makes it into the container. Cleaning the machine is straightforward—the assembly disassembles easily—but it’s not the fastest cleanup. If you’re the type who values pristine juice above all else, you might want to consider competing models, though none match the Slowstar AI’s speed and versatility across the board.
Pricing and Where to Buy
In the US, the Tribest Slowstar AI juicer retails for $399.95, but Target occasionally discounts it to $349.95. Wayfair estimates it will be back in stock on February 7, 2026, at the regular $399.95 price. A promotional code (DJX) offers $180 off through April 11, 2026, dropping the price significantly, with 10% discounts applying afterward. In the UK, it’s priced at £438 with free delivery and currently in stock.
The cost is high, but it reflects the machine’s capabilities. Older Slowstar Vertical models without AI cost $399–$449 and scored poorly on overall performance despite excelling with leafy greens. The AI version’s speed advantage and multi-function design justify the premium over those predecessors.
Should You Buy the Tribest Slowstar AI Juicer?
If you want the fastest, most intuitive slow juicer available and don’t mind a small amount of pulp in your juice, the Tribest Slowstar AI juicer is worth the investment. The AI speed control is genuinely clever, the vertical hopper eliminates frustration, and the sorbet function adds real value. The touch screen is intuitive, and the machine handles everything from leafy greens to hard fruits without constant intervention. For someone who juices regularly and values convenience and versatility, this is an excellent choice.
However, if you’re obsessive about pulp-free juice or on a tight budget, look elsewhere. The Kuvings Auto8 is slower but still competent, and cheaper models exist if you’re willing to sacrifice some intelligence and speed. But for the person who wants a single machine that juices, makes sorbet, and handles nut butters—and who appreciates the speed of AI-driven automation—the Tribest Slowstar AI juicer delivers.
Is the Tribest Slowstar AI juicer worth the price compared to older Slowstar models?
Yes. The older Slowstar Vertical juicers cost the same or more but lack AI speed adjustment and scored poorly on overall performance, outperformed by much cheaper alternatives. The AI version’s variable speed and multi-function design justify the premium.
How does the Tribest Slowstar AI juicer compare to centrifugal juicers?
Centrifugal juicers are faster but produce pulp-free juice and generate more heat, which can degrade nutrients. The Tribest Slowstar AI juicer is slower but operates at low speeds for gentler extraction and produces thicker, nutrient-dense juice with minor pulp.
Can the Tribest Slowstar AI juicer make nut butters?
Yes. It includes a homogenizing attachment for making nut butters, purees, and sorbet in addition to juice. This multi-function capability is one of its key advantages over single-purpose juicers.
The Tribest Slowstar AI juicer is the juicer to buy if you want intelligence, speed, and versatility in one machine—just accept that a tiny bit of pulp is the price of admission.
