What SpacePrompts is

SpacePrompts helps people and teams save, organize, test, version, and reuse AI prompts through a web service, browser extensions, and an API. Its Playground combines an editor, variables, model selection, and immediate runs; an Evaluator scores prompts, highlights weak areas, and offers improvement guidance. Each save creates a version that users can roll back. The prompt manager extension for Chrome, Edge, and Firefox can save highlighted webpage text. A separate token counter supports OpenAI, Claude, Gemini, and DeepSeek, displaying token counts and estimated costs. Free includes 50 prompts and limits of three daily AI enhancements, generations, and Playground runs. Pro costs $5 per month billed annually and adds API access; Team costs $9 per month billed annually for up to five members, shared prompts, collaborative editing, and role-based permissions. API keys are limited to 60 requests per minute. The token counter sends text to the API and says it does not retain it after responding; the prompt manager syncs prompts to its servers and caches prompts and authentication tokens locally.
