Affiliate disclosure: This review contains affiliate links to Meridian. If you buy through them, BookPublisherTools earns a commission at no extra cost to you. WarriorPlus pays affiliates 50% of every sale in the funnel, so I have a reason to be positive and I’d rather you knew it. Puzzle Maker Pro, which I mention near the end, is our own product.
This is a research-based review, not a hands-on test. I haven’t bought Meridian or generated a book with it. Everything below comes from the sales page, the affiliate (JV) page, the terms, refund policy and disclaimer, and the WarriorPlus checkout page, all read on 4 October 2026, plus KDP’s own help pages. Where I couldn’t check something, I say so.
The short version
Meridian is a $17 web app that turns a town name into a 140-page, 6 x 9 KDP interior of computed data (moon phases, sun times, solunar periods, prayer times and more), with a cover and listing copy. The idea is sound: local almanacs are real products, and computing 365 days of accurate data for one town is tedious.
But three things matter more than the feature list:
- There are no refunds. All sales are final.
- “Claimed” towns are only protected from other Meridian users. Anyone else can still publish a book for the same town.
- The volume pitch runs into KDP’s new cap. KDP now lets you create 2 new titles per book format each week. At that pace the front end’s 25 claims take about three months of paperback slots to publish, and the Publisher Tier’s 100 claims take most of a year.
If you want one or two carefully made local books and you’re willing to add your own pages to them, Meridian may save you real work. If you were hoping to fill a shelf with towns, the cap and the risk of near-identical books make that a poor plan whatever tool you use.
What Meridian is
According to the sales page, you pick a template, type a town and download a ZIP about two minutes later. It contains a print-ready interior, a full-wrap cover, a title, subtitle, description, seven keywords and a “claim certificate”. The maker is Thu Thao (WarriorPlus vendor thuthao0402), under the Nova AI Platform name. It launched on WarriorPlus on 25 September 2026.
The five front-end templates are:
- Night Sky: moon phases, moonrise and moonset, dark-sky nights and meteor showers, positioned as a gift keepsake.
- Solunar Fishing: major and minor periods, day ratings and a fishing log.
- When to Plant and The Weather Year: US only, in English, based on NOAA data.
- Prayer Times: six calculation conventions.
The page claims 257,000+ towns in 14 countries, books in five languages (English, German, French, Spanish and Italian), keepsake editions for years back to 1940 with that year’s daylight-saving rules, three interior themes and a dedication page. An earlier affiliate page quoted much smaller town counts, so the number has grown since launch.
Price, funnel and refunds
| Step | What it is | Price |
|---|---|---|
| Front end | Meridian: 5 templates, 25 claims, 2027 edition year, batches of up to 10 towns | $17 |
| Order bump | Cover Pack: 18 editable cover source templates | $9 |
| Upsell 1 | Template Vault: Golden Hour, Hunting Solunar, Moon Gardening, Tide Log (US coast) | $37 |
| Upsell 2 | Publisher Tier: 100 claims per edition year, 25-town batches, catalog CSV | $67 |
| Upsell 3 | Annual Editions Club: future edition years | $47 |
The full funnel comes to $177. Prices are from the JV page, and the $17 and $9 prices are confirmed on the checkout page.
Refunds: there aren’t any. The sales page and the refund policy say “All sales are final”, and the WarriorPlus checkout lists a refund period of zero days. The refund policy adds that a chargeback “automatically revokes the licence and releases the location claims”. Oddly, the terms page still says that if you don’t agree, you can “request a refund within the guarantee window”. I’d treat the refund policy and checkout as the real answer: assume you can’t get your money back.
The claims audit
Here is how the main sales claims hold up against the vendor’s own fine print and against KDP’s rules.
“Get a book nobody else can publish”
The headline promises “books your competitors physically cannot make”. The FAQ and terms explain what that means. When you generate a book, that template, town, year and language combination is locked to your account, so other Meridian users see it as taken. The terms say claims “do not confer any trademark or legal exclusivity outside this service”. Anyone with an astronomy library, a spreadsheet or another tool can publish a moon calendar for the same town.
Verdict: overstated. A claim stops duplicate books from Meridian users, which is useful. It doesn’t keep competitors away.
“None of this trips an AI content filter”
The vendor’s reasoning is that the interiors are computed tables with no generated text. That may well be true of the tables. But it answers the wrong question. The bigger risk for this kind of book is repetition. KDP’s general content guidelines say “Books for sale on Amazon should provide a positive customer experience” and that KDP doesn’t allow content that’s typically disappointing to customers, “including the examples provided in the Guide to Kindle Content Quality”. That guide is written for Kindle eBooks, and one of its examples is content that is “excessively reused, recycled, or repeated within or across books”. KDP doesn’t spell out a separate paperback rule, so treat this as a risk inferred from its Kindle guidance rather than a stated print policy. Still, twenty almanacs with identical page designs, where only the numbers and the town name change, look a lot like what that example describes. The listing copy Meridian writes for you is text, too. To its credit, the vendor’s FAQ says you should still follow Amazon’s disclosure rules for anything you add. The same content guidelines page covers KDP’s AI questions.
Verdict: incomplete. The real risk isn’t an “AI filter”. It’s near-identical books, which KDP’s guidance treats as disappointing content.
“1,384 towns already claimed”
This figure sits in the sales page’s top bar. I couldn’t confirm that it’s a live count. The only countdown I found in the page code counts down to the launch start, not to any end date.
Verdict: unverified. Don’t let it rush you.
“Worth $50–150 per interior” and “30+ hours per book”
These are the vendor’s comparison figures for hiring a designer or compiling the data yourself. No source is given. Doing it yourself is slow the first time, but with an astronomy library it gets much faster for the second town.
Verdict: vendor estimates.
“The price goes up after launch week”
The launch was on 25 September 2026. On 4 October, nine days later, the page still said “Why only $17? Because it’s launch week”, and the checkout still charged $17. No end date is published.
Verdict: unverified urgency. It may go up. Decide on the merits.
Covers: included, or part of the bump?
The sales page FAQ says covers are included with every book and that the $9 Cover Pack only gives you editable sources. The checkout bump text reads as if the bump is what adds “a print-ready, full-wrap KDP cover PDF” to every book.
Verdict: contradictory wording. Going by the FAQ, you don’t need the bump for a cover. Since there are no refunds, ask support before you buy if it matters to you.
Market proof screenshots
The page shows Amazon search results for almanacs with Best Seller badges, and mentions an Etsy star-map shop with 35,000+ reviews. Those are other people’s products. They show the category has buyers, not that Meridian books sell. The vendor’s own disclaimer is more sober: “most per-location titles in this category sell modest volumes.”
Verdict: market context, not evidence.
The volume pitch against KDP’s 2-titles-a-week cap
This is the part of the pitch that has aged fastest. The sales page asks if you “think in catalogs and seasons, not one lottery ticket”, and the “No – if” list warns that “long-tail means volume and patience”. The JV page tells affiliates “the win is a catalog of towns you own”. The upsells follow the same logic: 100 claims, 25-town batches, a catalog CSV, and “whole-shelf generation”.
Then KDP changed the rules. Its help page now says it limits title creation “to 2 per book format each week” (KDP: Create a Book, checked 4 October 2026). Publishers Lunch reported that the limit took effect on 21 September 2026, down from 10, four days before Meridian launched. It resets on Sunday at 12:00 AM UTC (Publishers Lunch).
Here’s the arithmetic for paperbacks, assuming you publish nothing else at all:
- One 10-town front-end batch: 5 weeks of paperback slots.
- The front end’s 25 claims: 12.5 weeks, about three months.
- One 25-town Publisher Tier batch: 12.5 weeks.
- The Publisher Tier’s 100 claims: 50 weeks, almost a full year.
Those slots are shared with every other paperback you publish. And because claims are tied to an edition year, a 2027 calendar published in late 2027 has little selling time left.
Is that the end of the idea? No. It changes what the tool is for. Under the cap, Meridian makes most sense as a way to get the data layer of a few carefully chosen books right, not as a catalog machine. That also happens to be the safer approach given KDP’s guidance on repeated content. One puzzle publisher on r/KDP put it simply: “Fewer, better-proofed books outperformed pumping out volume. Reviews improved, refunds dropped.”
Verdict: the volume upsells are much less useful than they look. The Publisher Tier in particular sells capacity most publishers can’t use under the cap.
What the vendor gets right
To be fair, the sales material is more honest than many launch pages:
- It says plainly that it’s “a tool, not a paycheck” and that you shouldn’t expect every book to sell.
- The disclaimer makes no income promises and says the data are predictions, “NOT for navigation”.
- The FAQ says weather values NOAA doesn’t publish come out as a dash rather than an invented figure, and that past-year editions use that year’s daylight-saving rules.
These are the right instincts for a data book. I haven’t been able to check the output, though.
A note on other Meridian reviews
Most Meridian reviews online are launch affiliate pages. Two that I read carry word-for-word identical text, including a first-person “cost me $17” story, and I couldn’t find an affiliate disclosure on either. Another lists the wrong official website. Read any review, including this one, with that in mind.
Who might buy it, and who should skip it
It might suit you if:
- You want to publish one or two local data books (a hometown night-sky keepsake, a fishing log for one lake) and you’ll add original pages to each.
- You don’t want to compute moon or sun times yourself and $17 is easy to lose.
- You’re comfortable checking a few dates against a published source before you print.
Skip it if:
- You need a refund option. There isn’t one.
- Your plan depends on publishing many towns quickly. The cap and KDP’s guidance on repeated content work against that.
- You want exclusivity. Claims only apply inside Meridian.
- You’re outside the US and want the planting or weather templates. Those are US-only.
Alternatives
- Do it yourself. An open-source astronomy library such as PyEphem and a spreadsheet can produce moon and sun tables for any town, and you can check them against the US Naval Observatory or timeanddate.com. It takes longer, but you can build the result into any design. My guides to the 2027 moon phase calendar book and the fishing log book walk through both routes.
- General planner generators such as KDP Builder’s AI Planner Creator or KDPEasy’s journals and planners make dated interiors, but they don’t compute data for a specific town.
Where Puzzle Maker Pro fits
Puzzle Maker Pro doesn’t compute moon or tide data, so it isn’t a replacement for Meridian. It covers the other half of the job: making a local book worth buying. A themed puzzle section is original content that makes a data book different from the next one. Standard Word Search builds fishing, hunting or astronomy word searches from a plain word list, and Puzzle Book Studio assembles puzzle pages with a solutions section. It also works as a second book for the same reader, such as a large-print fishing or astronomy word search book (large-print puzzle books for KDP). Every paid edition lets you sell the books you make; see commercial rights explained.
FAQ
Is Meridian worth $17?
It might be if you’ll publish one or two local books and add your own pages. It isn’t if you expect a catalog of towns to sell by itself. Remember there are no refunds.
Does Meridian offer refunds?
No. The refund policy and checkout say all sales are final, even though the terms page mentions a “guarantee window”. A chargeback revokes the licence and releases your claims.
Does a Meridian claim stop other people publishing the same town?
Only other Meridian users. The terms say claims give no exclusivity outside the service.
How does KDP’s weekly limit affect Meridian?
KDP lets you create 2 new titles per book format each week. Publishing the front end’s 25 claims as paperbacks takes about 12.5 weeks of slots, and the Publisher Tier’s 100 claims about 50 weeks, if you publish nothing else.
Will KDP reject Meridian books as AI content?
The vendor says the interiors contain no generated text. The bigger risk is near-identical books. KDP’s Kindle quality guide lists content “repeated within or across books” as disappointing, and its general content guidelines point to that guide, so make each book meaningfully different.
