A chat guesses. L-Guard counts.
Titles and fees are checked by the same code that runs L-Guard's tools, with the rule's date and source.
The title Hearthline USB-C to USB-C Charger Cable, 6 ft, 2-Pack, 2 Cords, Braided, Fast Charging Cord for Phone, Tablet and Laptop has 120 characters; the limit is 75. After nine cuts it reads Hearthline USB-C to USB-C Cable, 6 ft, 2-Pack, Braided, Fast Charging: 69 of 75, pass. Rule: titles up to 75 characters since Jul 27, 2026, counted by L-Guard's LSRules.
Scores always come from code.

Questions
Is this an Amazon program?
No. L-ASINAUT is an independent training tool by L-Guard. It is not Amazon and is not affiliated with, endorsed by or sponsored by Amazon.
Do I need an Amazon seller account?
No. The lessons need no account, and when the training store opens you work with fictional products and data. L-ASINAUT never asks for an Amazon login.
What is free?
Now: three lessons (a tour of the seller account; ASIN, SKU and FNSKU; titles in 75 characters) and the reference pages: the glossary, Where things moved in the new Seller Central and the rule changes. When the training store opens, the first task “title under 75” is free too. Everything else is in the full path ($129, one payment), which opens in November 2026.
How much?
The full path is $129, one payment, with 12 months of access to all three levels. Everything we add during those 12 months is included. Paid access opens in November 2026. The three lessons and the reference pages stay free.
Who grades my work?
Code. Titles, fees and reimbursements are checked by the same engines that run L-Guard's tools. AI never gives a score.
Is there AI?
The first school release does not include an AI coach. Exercise scores come from rule-based code. The site's separate support chat uses AI.
Which levels will there be?
Three: complete beginner, intermediate and pro. The three free lessons come from the beginner level. When paid access opens in November 2026, the beginner level is complete (79 lessons, module tests and practice tasks). Intermediate and pro open with their first cases, and new cases are added regularly.
How current are the rules?
Every fee and listing rule shows its date and source. When Amazon changes a rule the school uses, the change is listed with its date on a public page.

In November 2026. Join the early-access list and we'll email you when paid access opens.
