Promptly

Promptly is a no-code platform for building generative AI applications, agents, and chatbots. Users assemble apps in a visual builder, chaining together large language models from providers including OpenAI, Cohere, Stability AI, and Hugging Face without writing code. Apps can pull in outside knowledge through retrieval-augmented generation, with data sources such as website URLs, sitemaps, PDFs, YouTube links, Google Drive, and Notion exports attached directly in the builder. Once built, apps are deployed as web widgets, Slack apps, or Discord bots, or called through streaming APIs for embedding into existing products. Promptly targets teams inside larger organizations — sales, marketing, HR, and engineering groups are named specifically — as well as individual developers who want to skip backend setup. The platform includes prebuilt templates for common jobs like content generation, data analysis, and customer support automation, plus collaborative permissions for teams building apps together. Pricing runs from a free tier (10 apps, 1M characters of storage) through a $99.99/month Pro plan (100 apps, 100M storage) to custom Enterprise pricing. One limitation: app and storage limits are the main constraint rather than usage-based pricing, which may not suit teams running many small, high-volume bots.
