Esergon vs PromptMax

Esergon generates Shopify product listing content from a product photo or name, including titles, SEO meta descriptions, tags, bullet points, and URL handles. It supports JPEG, PNG, and WebP uploads and says a complete listing takes under 10 seconds to generate. After connecting a Shopify store through OAuth, users can push listings containing price, quantity, SKU, and vendor. Bulk mode accepts up to 20 product names in one job and can send results to Shopify together. The web service has a free plan with five listings per month and paid plans at $19 a month, $49 a month, and $99 a month. Higher plans raise listing allowances; Agency includes unlimited stores, five team seats, shared quota, usage tracking, connection permissions, and a dedicated API key. Esergon is intended for solo sellers, growing stores, agencies, and owners of multiple Shopify stores. Uploaded images go to OpenAI's API for analysis and are not permanently stored by Esergon. Generated listing history is retained indefinitely, while account data is permanently removed within 30 days after account deletion.

PromptMax turns rows in a CSV spreadsheet into completed output using a prompt and a selected AI model. It supports 14 models from Google Gemini, Anthropic Claude, OpenAI GPT, and xAI Grok, and a job can process up to 50,000 rows. The stated maximum file size is 10 MB. Users can preview the first 10 rows for free and see an estimated job cost before submitting. Saved prompts and smart model routing are available; routing recommends a model based on the prompt and sample rows. Direct Excel input is on the roadmap, while current jobs use CSV. The site says uploaded files are stored in Google Cloud Storage in the UK London region, isolated to the user's account, and not used to train AI. Selected AI providers may process data outside the UK, including in the United States, under stated safeguards. A free signup provides £5 credit without a card. Flexible top-ups start at £10, and enterprise setup is for teams spending £1,000+/month. PromptMax describes its audience as professionals and small teams, including marketers, SEO specialists, e-commerce managers, content teams, and researchers.
