The short answer: for most Amazon sellers in 2026, Helium 10 is still the default all-in-one toolkit — but its price floor moved. The old $39 Starter plan is gone, so the real choice is Helium 10 Platinum from $99/month, Jungle Scout from $29/month if research is all you need, or SellerApp’s free plan if you are just starting. Once ads eat real money, Perpetua and Teikametrics automate the bidding. Every price below was checked against the vendor’s own pricing page or pricing FAQ in late October / early November 2026.

1. Helium 10 — best all-in-one toolkit
Price: Platinum $99/month billed annually or $129 month-to-month; Diamond $279/$359; Enterprise from $1,499/month. A limited free plan remains.
Helium 10 bundles 30-plus tools under one login: Black Box for product research, Cerebro and Magnet for keywords, an AI Listing Builder that drafts optimized copy, profit tracking, inventory alerts and review automation. It is the suite most sellers measure everything else against, and it now reaches into Walmart and TikTok Shop too. If you sell across your own store as well, pair it with the stack in our roundup of AI tools for e-commerce store owners.
Best for: established sellers who want one subscription instead of five.
2. Jungle Scout — best product research on a budget
Price: Catalyst Starter $29/month billed annually ($49 monthly), Growth Accelerator $49/$79, Brand Owner + CI $129/$149.
Jungle Scout is the research-first alternative: product database, opportunity finder, keyword scout and supplier database, with AI Assist summarizing reviews and listing data. It deliberately does less than Helium 10 — no deep ads automation — and charges less for it. For a first product launch, that focus is a feature, not a gap. Sellers on handmade marketplaces should also see our Etsy sellers roundup, where the economics are different.
Best for: new and growing sellers validating products before they spend on ads.
3. SellerApp — best free start
Price: Freemium $0 forever with no credit card; Pro from $99/month; Smart plan with ads automation listed at $149/month.
SellerApp’s free tier is the real thing: product research, keyword and listing-quality checks, and tracking for two products, free indefinitely. Paid plans widen the tracking limits and add PPC automation and a listing quality index. It is the lowest-risk way to learn what seller data actually tells you before you commit to a suite — the same reason it anchors the budget end of our small business owners stack.
Best for: beginners and lean sellers who want real data at $0 first.
4. Perpetua — best hands-off ads AI for bigger spenders
Price: Essentials $695/month covering up to $10,000/month in ad spend; Growth is $695/month plus a percentage of ad spend above that; Premium is custom. There is no free trial — entry is through a demo.
Perpetua works the way busy brands want: set a target ACoS and budget, and its engine handles bid adjustments, keyword harvesting and campaign structure across Sponsored Products, Brands and Display, plus Amazon DSP and Walmart. The math only works at scale — at $5,000/month in ad spend, the $695 fee alone is 14% on top of your ads.
Best for: brands spending $10,000 or more a month on Amazon ads.
5. Teikametrics — best margin-aware ad optimization
Price: Essentials $179/month ($149/month billed annually) covering up to $10,000/month in ad spend, then 3% of spend above that threshold.
Teikametrics’ Flywheel platform bids against your actual product economics — margin, inventory and sales velocity — rather than a raw ACoS target, and its AI hourly bidding reacts faster than weekly manual reviews. It sits in the gap between doing ads yourself inside Helium 10 and handing everything to Perpetua.
Best for: mid-size sellers whose ad spend has outgrown manual bidding.
6. Amazon Seller Central AI — best zero-cost listing help
Price: Included with your seller account at no extra tool cost.
Before paying anyone, use what Amazon already gives you: Seller Central’s generative AI listing tools draft titles, bullet points and descriptions from a product photo, a URL or a few keywords. The copy needs an edit and a keyword pass, but for a first listing draft it is genuinely useful — and it is the one tool on this list that can never raise its price on you.
Best for: every seller, as the first draft before paid optimization.
What the pricing pages don’t make obvious
Four details verified on the vendors’ own pages and FAQs that change what you will actually pay. Helium 10 retired its $39 Starter plan in January 2026, so any guide still quoting it is out of date — and since April 2026 its Ads product sits only on the Diamond plan and adds a 2% fee on managed ad spend. Jungle Scout offers no free trial at all: you pay first and rely on a 7-day money-back guarantee that you have to request. SellerApp’s Smart plan headline of $149/month is, per its own pricing footnote, a discounted rate for the first three months only, against a $250 standard rate. And Perpetua’s Growth tier adds a percentage of ad spend that the vendor does not publish — get it in writing before you sign.
Frequently asked questions
What is the best AI tool for Amazon sellers?
Helium 10, if you can justify $99/month: nothing else covers research, listings, ads and profits in one login. Jungle Scout is the smarter buy when product research is the only job.
Is there a free AI tool for Amazon sellers?
Yes. SellerApp’s Freemium plan is free forever with no credit card, Helium 10 keeps a limited free plan, and Amazon’s own generative listing tools inside Seller Central cost nothing extra.
Helium 10 or Jungle Scout — which is cheaper in 2026?
Jungle Scout, clearly: $29/month billed annually against Helium 10’s $99, because Helium 10 dropped its budget tier. The gap buys you ads, inventory and profit tooling you may not need yet.
When is Perpetua worth $695 a month?
When your ad spend passes roughly $10,000/month and your time is worth more than the fee. Below that, the flat fee eats the savings the AI creates.
The verdict: which stack should you buy?
Just starting: SellerApp free plus Amazon’s built-in listing AI costs nothing and teaches you the data. Launching products: Jungle Scout at $29/month billed annually. Scaling a real catalog: Helium 10 Platinum, stepping up to Diamond only when the ads fee math works. Spending five figures a month on ads: get written quotes from Perpetua and Teikametrics and compare the percentage terms line by line — that, not the headline price, is where the real cost lives.
