promptmate.io

promptmate.io is a platform for building applications that combine multiple AI systems in multi-step prompt chains. It addresses the need to connect prompts with external data, process large datasets, and move results into other tools without handling AI provider API keys directly.

Core capabilities include selecting among AI systems such as ChatGPT, Mistral AI, Claude, Gemini, StabilityAI and Perplexity AI, chaining them across workflow steps, and enriching prompts with data extenders. Users can upload CSV files for bulk processing and export results to CSV or Google Spreadsheet, automate workflows through Zapier, and access an API. Ready-to-use templates cover use cases such as SEO analysis, social media content generation, social listening, competitor analysis, blog writing and marketing planning, and can be edited to fit specific needs.

Plans are credit-based and month-to-month, with a free tier that requires no credit card, paid tiers with higher credit and bulk-row allowances, and an Enterprise option with team members and additional support. Credits are shared across a team, and plans can be upgraded or downgraded at any time.
