A cost optimization infrastructure for LLM applications
Promptly is an OpenAI-compatible proxy that reduces your LLM expenses by up to 60% through intelligent routing, prompt optimization, semantic caching, and context pruning. Works with OpenAI, Anthropic, and Google.
For solopreneurs offering AI-powered services, Promptly enables significant cost reduction on LLM API calls. Example: A freelance copywriter using GPT-4 for client content generation can reduce their monthly API spend by up to 60% by routing requests through Promptly, which optimizes prompts and caches common responses.
For early-stage startups with customer support needs, Promptly enables cost-effective scaling of LLM-powered chatbots. Example: A SaaS startup can deploy an OpenAI-compatible chatbot that handles customer inquiries, with Promptly intelligently routing requests and pruning context to cut operational costs by up to 60%.
For developers building LLM-powered applications, Promptly enables budget-friendly integration of OpenAI, Anthropic, and Google models. Example: A developer building a content summarization tool can use Promptly to manage API calls, optimize prompts for efficiency, and reduce overall LLM expenses by up to 60%.
For academic researchers leveraging LLMs for data analysis, Promptly facilitates cost-effective processing of large datasets. Example: A researcher analyzing sentiment from thousands of text documents can use Promptly to intelligently route requests to the most cost-effective model and utilize semantic caching, reducing their LLM expenditure by up to 60%.
Promptly offers a free tier that includes unlimited sessions, cost estimates for over 250 models, local SQLite storage, a built-in dashboard, and is suitable for single users. This plan is fully offline and allows you to track your AI usage without charge.
Promptly has a 'Team' plan priced at $15/month (with a 50% early access discount, normally $30/month). This plan includes all free features plus dollar cost analytics, monthly token budgets, session bookmarking, per-developer breakdowns, and support for unlimited team members. A 14-day free trial is available for the Team plan.
Promptly emphasizes data isolation, with team sessions only visible to authorized team members and strict access controls. Conversation data is isolated per-user and per-team, with no cross-tenant data access. A local-first option is available, allowing you to keep all data on your machine with no cloud requirement.
Promptly is available as a command-line interface (CLI) tool, indicated by the npm installation command. The tool offers a built-in dashboard for tracking and analytics, and a local-first option with SQLite storage suggests a desktop or local server-based functionality. There is no explicit mention of dedicated mobile or web applications in the provided information.
You can install Promptly globally via npm by running the command `npm i -g @getpromptly/cli`. After installation, you can initialize it with `promptly init` and start capturing sessions with `promptly start TICKET-1`.
Promptly provides cost analytics in dollars, not just tokens, with breakdowns by team, developer, and model. It allows you to set monthly token budgets with alert thresholds and track AI sessions tied to project tickets. Features also include session starring for exemplary sessions and support for multiple AI tools like Claude, GPT, and Gemini.
