In their own words
Blurbi
Blurbi creates product listings for online marketplaces from product details or an uploaded photo. Its modes cover eBay, Etsy, Amazon, Shopify, Depop, Facebook Marketplace, and a generic option for other platforms. Sellers can select Professional, Casual, Luxury, Fun, or Minimal tones. The web service and Chrome extension have a free plan with five descriptions per month; photo listings are subject to plan limits. The extension places a Blurbi button on listing pages for eBay, Etsy, Amazon, Shopify, and Depop, where users can generate and copy a description. Pro offers unlimited descriptions and photo listings, priority generation, email support, and bulk CSV generation for up to 100 products at a time. Pro costs £9/month or £79/year. An account is needed beyond the public landing-page demo, and users must be at least 16. Blurbi says it does not sell user data or use inputs to train AI models; product details and optional photos are sent to Anthropic's Claude API to generate descriptions.
PromptMax
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.
