In their own words
PromptFluent
PromptFluent is an AI prompt and workflow management platform focused on enterprise governance and execution intelligence. Its library advertises more than 20,000 practitioner-built prompts across 13 business functions and more than 30 industries. Prompt Studio creates structured prompts, adapts library prompts, builds multi-step chains and saves work to versioned personal or team libraries. Team capabilities include shared libraries, approvals, version control and role-based access; analytics surface patterns, trends, anomalies and recommendations across shared AI work. A Chrome or Edge extension searches and inserts prompts inside ChatGPT, Claude, Gemini, Copilot and Perplexity, and supports Windows, macOS, Linux and ChromeOS. PromptFluent says customer data is encrypted at rest and in transit, organization data is isolated with row-level security, and private business material is not used to train public AI models. Free access is available; Pro costs $25 a month when billed annually. Team costs $50 a month when billed annually per user. Enterprise pricing is custom through a limited Founding Customer Program.
SpacePrompts
SpacePrompts is a prompt management platform for people and teams working with AI. It runs on the web, through an API, and with Chrome, Edge, and Firefox extensions. Users can save, organize, run, version, and reuse prompts. The Playground combines an editor, variables, model selection, and immediate runs. An Evaluator scores prompts, highlights weak areas, and gives improvement guidance. Every save creates a version that can be restored later. The prompt manager extension can turn highlighted webpage text into a prompt. Its token counter supports OpenAI, Claude, Gemini, and DeepSeek models, showing token counts and estimated costs. Pro and Team plans provide API access, limited to 60 requests per minute per key. Team workspaces add shared libraries, collaborative editing, and role permissions for up to five members. Free includes 50 prompts and daily usage limits; Pro is $5 a month billed annually, and Team is $9 a month billed annually.
