Summarize with AI
If you want an Adigy alternative, the main question is how much you want the software to decide for you. Adigy runs your Amazon ads on its own, including building campaigns, starting at $249 a month. BookBidder automates your bids and asks before making bigger changes, starting at $49 a month with no percentage of ad spend. If you want hands-off automation and the price fits your royalties, Adigy is a solid choice. If you want automation with the final say at a lower flat price, BookBidder is the better fit.
We built BookBidder, so we're biased. Where Adigy is the better fit, we say so. Adigy's details were checked on its own website in October 2026.

Where BookBidder wins over Adigy
- Price: $49 to $199 a month by ad spend, compared with $249 a month and up. At every spend level in the table above, BookBidder costs less.
- No percentage of your ad spend: your price stays flat within each spend band. With Adigy, every dollar above $2,000 adds 3.3% to your bill.
- You approve the bigger changes: BookBidder handles bids and pauses targets that aren't selling, but new campaigns and new exact-match keywords wait for your OK. With Adigy, the software makes those calls.
- More marketplaces: 23 Amazon marketplaces, compared with Adigy's 12.
- Simpler to run: Adigy's interface is less intuitive and more complex than most KDP authors need. BookBidder does fewer things on purpose: good bids, cutting targets that don't sell, and promoting your best search terms.
Where Adigy is the better fit
- It builds campaigns for you. If you're starting from zero and want the software to create your campaign structure, Adigy does that. BookBidder manages campaigns you've built and adds new ones only from search terms that already sell.
- It manages budgets and placements. Adigy adjusts your campaign budgets and placements. BookBidder doesn't change your existing campaign budgets.
- It updates hourly. Adigy says it makes hourly updates. BookBidder adjusts bids twice a day.
- It runs audiobook ads. Adigy supports Audible audiobook ads for ACX-published books. BookBidder doesn't yet.
- It has a money-back guarantee and a course. Adigy offers a 30-day money-back guarantee on your first payment and includes a video course with every account.
If those matter more to you than price and control, Adigy is a reasonable choice.
Who should choose Adigy, and who should choose BookBidder
Choose Adigy if:
- You want to set a target and let the software run everything, including new campaigns.
- You run audiobook ads for ACX titles.
- You're comfortable paying $249 a month or more, and your royalties cover it easily.
Choose BookBidder if:
- You spend $1,000 or more a month on ads and want automation with your approval on bigger changes and more control over your book business.
- You already have campaigns that work and want them managed as they are.
- You want a flat price that doesn't grow with every dollar of ad spend.
- You advertise in marketplaces Adigy doesn't cover.
How to switch from Adigy to BookBidder
- Start a BookBidder trial and connect your Amazon Ads account. It takes about two minutes.
- Pick the campaigns BookBidder should manage. Campaigns Adigy created are regular Amazon campaigns, so BookBidder can manage them too.
- Turn off Adigy's management for those campaigns first. Two tools changing the same bids will work against each other.
- Choose a bid strategy for each campaign, like Target ACOS, and set up your Smart Rules.
- Install the KDP Sync extension so you keep seeing profit per book.
- Cancel Adigy once you're happy. Its 30-day money-back guarantee covers your first payment.
Frequently asked questions

Yes. Adigy was previously called Adsology, so older reviews and videos may use either name. It's Amazon Ads software built for KDP authors and publishers.
How much does Adigy cost?
Adigy is $249 a month, which includes up to $2,000 of monthly ad spend. Above that, it adds 3.3% of the extra spend. At $3,000 a month in ad spend that's about $282, and at $10,000 it's about $513. Adigy offers a 30-day money-back guarantee on your first payment.
Is there a cheaper alternative to Adigy for KDP authors?
Yes. BookBidder is Amazon Ads software for KDP authors that starts at $49 a month, with flat plans by ad spend and no percentage fee. Publishing Performance is $39 a month but optimizes only campaigns created in its own tool.
Does Adigy create campaigns for you?
Yes. Adigy creates and develops campaigns, and manages bids, budgets, placements, targeting and negatives within the limits you set. BookBidder manages the campaigns you already have and builds new campaigns only when you approve a suggestion.
Can I use BookBidder and Adigy at the same time?

Does BookBidder show profit per book like Adigy?
Yes. Both pull in your KDP royalties with a Chrome extension and show profit per book next to your ad spend. BookBidder's KDP Sync extension includes Kindle Unlimited page reads. Adigy can also connect to Publisher Champ.
