The Platform

Two Modules. One Workflow. One Subscription.

Build the listing. Audit how it's performing. Refine and repeat. SellerForge is the only platform where the writer and the grader share the same brain — so the audit knows what the builder did, and the builder knows what the audit found.

Listing Builder

BUILD

Generate a launch-ready listing from zero — title, bullets, A+, keywords, image briefs, pricing.

When → new SKU, relaunch, variant.

Output → ready to paste / bulk-upload to Seller Central.

Listing Audit

AUDIT

Score live listings across 10 dimensions — images, title, bullets, A+, COSMO, Alexa AI.

When → existing listing not converting.

Output → audit score + rewrite recommendations.

Refine & Re-audit

OPTIMIZE

Refine any section inline, push updates to Seller Central, re-audit every 90 days as the category evolves.

When → ongoing optimization.

Output → updated listing that lifts CVR over time.

Listing Builder

Write a Launch-Ready Listing in One Click.

From a working product name + a few photos + your unit cost, Claude generates the complete listing — title, bullets, A+ Content (or description), backend keywords, image briefs, and pricing — in one structured pass.

One-Pass Generation

Title, Bullets, Description, Keywords, Images, Pricing — One Click.

Most "AI listing tools" generate the title, then ask you to come back for the bullets, then come back again for the description. SellerForge generates everything in a single structured tool call — title, 5 bullets, description OR A+ modules, backend keywords, 7 image briefs, and a 3-tier pricing recommendation — in roughly 60 seconds. Compliance is checked before export. You review, refine any section, and ship.

Wizard → Generation → Output flow: a product wizard (name, category, Brand Registry, cost/margin, optional files) feeds a single Claude generate_listing tool call (~60 seconds) that outputs a title with mobile preview, 5 bullets, A+ Content or description, 249-byte backend keywords, browse node, 7 image briefs, 3-tier pricing, and compliance checks — export blocked until every check passes
A+ Content Listing Builder in SellerForge

A+ Content vs Description

Brand Registered? You Get A+ Modules. Not? You Get a Description. Always the Right Output.

Toggle the Brand Registry checkbox in the wizard and Claude switches output modes. Brand-registered sellers get a full A+ Content build — Standard Header Image + Text, Comparison Chart, Three Image + Text, FAQ module — with every module's copy and image prompt ready to paste into Seller Central's A+ Builder. Non-brand-registered sellers get a 2,000-character plain-text description tuned to do the same job within Amazon's stricter limits. The compliance validator enforces the right format for your account type — A+ on a non-brand-registered account is blocked before export.

COSMO + Alexa AI + A10

Tuned for the Algorithm That's Ranking You Right Now.

The A9 era ended in 2024. COSMO ranks listings by intent match — does your copy answer "who is this for," "what problem does it solve," "when/where/why use it"? Alexa for Shopping answers shopper questions conversationally, so the bullets that bake in answers to the top 5 questions in your category win the conversation. A10 weights conversion velocity, not just keyword presence. SellerForge writes for all three — the system prompt explicitly trains Claude on the 2026 ranking surface, not the 2018 one.

Bullet → COSMO Intent → Alexa AI Q&A: one bullet ('Precise slow pour: gooseneck spout controls water flow for even saturation') mapped to COSMO who / what / when-where-why intent slots and to the shopper questions Alexa for Shopping answers first — one bullet engineered for A10 + COSMO + Alexa AI, the 2026 ranking surface
Compliance checks panel in Listing Builder — 23 automated checks (title char count, byte budget, banned superlatives, CPSC/CPSIA, etc.) paired with the Seller Assistant's compliance summary showing what passes, what needs fixing, and where to upload supporting documentation

Compliance Gating

Export Is Blocked Until Every Compliance Check Passes.

Every listing is checked against Amazon's 2026 policies before export — no medical or disease claims ("cure," "treat," "FDA-approved"), no competitor brand names, no banned superlatives ("#1," "Best Seller"), no byte-budget overflows on backend keywords, no category-cap overruns on the title. If any check fails, the Export buttons are disabled and the failing checks are flagged inline. Use the Refine box on the affected section to fix it, re-check, and ship.

Image Briefs

7 Image Slots, 7 Midjourney-Ready Prompts. No Other Tool Does This.

Listing copy is half the listing. Images are the other half. SellerForge produces a complete 7-slot image plan with every slot role-tagged (white-background hero, lifestyle, dimensions, comparison, infographic, in-use, scale reference) per category convention. Each slot has a fully-written, Midjourney-ready prompt you can copy into your image generator or hand to a photographer. Slot 1 is always the white-background hero with a check that your generated prompt doesn't include text or logos that would violate Amazon's main-image policy.

Listing Audit

Diagnose Why Your Live Listing Isn't Converting — In Under 2 Minutes.

SellerForge analyzes your live Amazon listing across 10 dimensions and produces a scored, annotated audit with specific rewrite suggestions. Built on Claude's vision API — yes, it analyzes the images, not just the text.

10-Dimension Scoring

One Score Per Dimension. No Vague Grades.

Title, bullets, description, A+ Content, image stack, backend keywords, top keywords, COSMO semantic readiness, Alexa AI readiness, and pricing competitiveness — each scored 0–100 with the underlying reasoning. The radar chart overlays your scores against the category top-10 benchmark so you see exactly which dimensions are dragging the listing down. Re-run after edits to track improvement, and compare audit-over-audit on the trend sparkline.

Listing audit summary — overall 52/100 score with a 7-dimension radar chart benchmarked against the category top-10, plus per-dimension bars for images, title, bullets, description, backend keywords, COSMO semantic, and Alexa AI readiness
Image Analysis — main image (IMAGE 1) scored 72/100: a 'Strong: Goomy figure clearly visible' pin plus two warnings ('#1155 visible but not in listing' and 'choking-hazard warning on box'), each with an estimated conversion impact
Image Analysis — secondary image (IMAGE 2, PT01) scored 90/100: 'Strong: clean white background, excellent fill' and a 'Warning: add size-callout overlay' recommendation
Image Analysis — size-comparison image (IMAGE 3, PT02) scored 35/100: a critical 'Generic Funko figure, not Goomy' finding and a 'Strong: 4-inch Pop size clearly labeled' note

Image Analysis

Visual Annotations Pinned Directly On Your Images.

Images drive CTR. CTR drives ranking. Most listing audit tools score the images on a 1–10 scale and call it a day. SellerForge runs every image through Claude's vision API and overlays specific recommendations directly on the image — a pin pointing to "background not pure RGB 255,255,255," another pointing to "product fills only 68% of frame, needs 85%." Hover any pin for the full recommendation. No other tool does image-level visual annotation.

A+ Content Breakdown

Every A+ Module Scored Individually.

Most tools treat A+ Content as a black box. SellerForge parses every module — Standard Header Image + Text, Comparison Chart, Three Image + Text, Brand Story, FAQ — and scores each module against best-practice patterns. Missing modules get a "recommend adding" callout with a ready-to-paste module spec. A+ is the highest-leverage section after images — most sellers under-invest here and pay for it in conversion rate.

Listing audit — A+ content brief, part 1
Listing audit — A+ content brief, part 2
Top Keyword Analysis table — ten keywords scored by volume, saturation, opportunity, and a composite score, each tagged Push, Add, or Improve, with 'in listing' badges showing which are already used

Keyword Analysis

Top Keywords Scored Against Volume, Saturation, and Ranking Potential.

Volume alone is vanity. SellerForge ranks every keyword you target by a composite opportunity score — search volume × ranking potential × current saturation × keyword–product relevance. Keywords that are winning are tagged "protect." Keywords with room to grow get "push." Keywords missing from the listing entirely get "add." The recommendation comes with the specific copy slot the keyword should live in (title front, bullet 2, backend).

COSMO + Alexa AI Readiness

Test the Listing Against the Algorithms That Are Actually Ranking It.

COSMO simulator scores your listing against 25+ intent slots — who-is-this-for, what-problem-does-it-solve, when-where-why-use-it. Gaps surface as "missing intent coverage" with the specific copy that would close the gap. The Alexa for Shopping simulator runs the top 5 likely shopper questions in your category through your listing and tells you which questions your bullets currently answer — and which they don't. No other audit tool tests the listing against the actual 2026 ranking surface.

COSMO Semantic Readiness query-coverage simulation — seven shopper queries each rated Strong, Partial, or No match against the listing, with a 45/100 score and a summary noting strong exact-keyword matching but weak semantic context

Built By A Seller, For Sellers

“The listings module is the one I rebuild every time the algorithm shifts. The 2026 COSMO + Alexa AI changes broke half of the playbooks I used at Worldfront. SellerForge is the first listing tool I've used that ranks for what Amazon is actually weighting today, not what it weighted three years ago.”

FAQ

Common Questions

Three things. (1) We generate the full listing — copy, backend keywords, A+ Content, image briefs, and pricing — in one pass. Helium 10's tool generates copy and integrates with their other tools for the rest. (2) We're built on Claude (Sonnet/Opus). Helium 10's AI Assist is built on ChatGPT. (3) Listing Builder is one of 19 modules included in $99/mo. Helium 10 Listing Builder requires the Platinum plan ($129/mo) or Diamond ($359/mo) for AI assistance.
Jungle Scout's Listing Builder generates copy and offers an instant listing rating. SellerForge does both — and adds image briefs, pricing recommendation, A+ Content module generation for brand-registered sellers, compliance gating, and ten other modules in the same subscription. Pricing is similar at the mid-tier ($99 vs Jungle Scout's $49–$199), but the SellerForge subscription covers your PPC, forecasting, reimbursements, and POAs too.
You can — and many sellers do — but ChatGPT doesn't know Amazon's 2026 policies, won't enforce the 249-byte backend keyword cap, won't switch between A+ Content and a plain description based on your Brand Registry status, can't analyze your reference images, and has no built-in compliance gating. ChatGPT will happily generate a title that violates Amazon's banned-superlatives rule and won't tell you. SellerForge is Claude with Amazon-specific guardrails, byte-budget enforcement, and the deterministic validators that block bad output before export.
No. The wizard has a Brand Registry checkbox. If you check it, you get full A+ Content modules. If you don't, you get a plain-text description that's tuned to do the same job within Amazon's stricter non-brand-registered limits. The compliance validator enforces the right format for your account type — you can't accidentally export A+ on a non-brand-registered account.
The 7-day free trial includes one Listing Builder generation — enough to test the full workflow end-to-end on one of your products. You can refine that listing as many times as you want during the trial. Paid plans ($99/mo) include unlimited generations. Trial exports include a small SellerForge watermark; paid exports do not.
SP-API push is on the roadmap (marked "Coming in v2" on the export page). For now, export to Amazon Flat-File (.xlsx), Markdown, or PDF — flat-file uploads directly via Seller Central's bulk upload, which is the fastest path. We expect to ship SP-API push by late Q3 2026.
The current Listing Builder generates one listing at a time. For variants, generate each child SKU independently then build out the variation relationship inside Seller Central — that's the workflow Amazon's own tools support best. Parent-listing variant generation is a planned v2 feature.
Listing Audit works two ways. (1) SP-API connected — paste an ASIN and SellerForge pulls the full listing automatically. (2) Not connected — paste the listing content directly into the audit wizard (title, bullets, description, image URLs) and the audit runs on what you provide. Most sellers connect SP-API for the convenience, but both paths produce the same audit.
About 60 seconds for the brain to generate, plus ~5–10 seconds for the deterministic compliance validators. Listing Audit on a live listing is closer to 90 seconds because it runs Claude's vision API across all images in parallel. Both fit comfortably inside one cup of coffee.
Yes. Everything you generate or audit is exported in standard formats (Markdown, .xlsx, .pdf) — once exported, it's yours. We don't lock content behind the subscription. Cancellation gives you 30 days of read-only access to re-export anything you haven't already grabbed.

Replace Your Listing Agency. Replace Your Copywriter. Replace Your ChatGPT Workflow. From $49/Month.

SellerForge writes the listing, audits the listing, and refines the listing — built on Claude, tuned for COSMO and Alexa for Shopping, and bundled with 10 other Amazon modules.
