PromptBase vs Coachvox AI

PromptBase is a prompt marketplace, an online store where you browse, buy, and sell tested text prompts for image, video, and chat models. The catalog lists more than 310,000 prompts for tools like Midjourney, ChatGPT Image, Gemini, Veo, FLUX, and Stable Diffusion, with individual listings priced from about $3.99 to $9.99.

Unlike general AI directories, PromptBase runs a two-sided store with seller analytics, Stripe payouts, and a subscription tier called PromptBase Select. Sellers keep 100% on referral-link sales but pay a 20% marketplace fee on in-site purchases, which is a trade-off most prompt libraries do not offer.

Prompt engineers, Etsy sellers, marketers, and indie creators use it to monetize prompt packs, find niche templates for printables and product shots, or hire experts through the built-in job board. The site also hosts agent skill files and a no-code app builder that turns prompts into shareable generators.

Coachvox AI is an AI coaching companion that trains a chatbot on your content, methods, and communication style so prospects and clients can talk to you anytime. Upload articles, transcripts, and frameworks, or connect Claude to build your model in under an hour. Every conversation can capture a lead, warm up prospects, and give existing clients answers between sessions.

Unlike generic chatbots that pull from the whole internet, Coachvox builds one AI per expert trained only on your material. The homepage positions it against ChatGPT custom GPTs: yours captures leads, supports clients, and nudges people toward working with you rather than answering like everyone else's assistant. You can embed it on your site, share a custom page, or charge for access through built-in Stripe billing.

Coaches, consultants, and expert-led business owners who want to scale their thinking without cloning themselves manually are the target audience. The platform includes content tools for LinkedIn posts, blog drafts, and short-form social copy written in your voice. Thousands of coaches use it, and Coachvox lists the International Coaching Federation as an official business partner.
