What your assistant can do

promptcuelab_search_prompts

Search the curated library of 100+ human-tested prompts by keyword, category, or profession — and get the full, ready-to-use prompt text back.

Free Open in Playground
promptcuelab_get_models

List AI models with live pricing, context window, and strengths — compare ChatGPT, Claude, Gemini and more before you pick one for a task.

Free Open in Playground
promptcuelab_refine_prompt

Rewrite a rough prompt into a structured, optimized one — role, context, instructions, output format, and constraints, with bracket placeholders.

Metered Open in Playground

And because your assistant reasons over the results, whole workflows come free: "find me a proven prompt for X and adapt it", "which model is cheapest for this job?", "refine this prompt and tell me what changed." Chain it with CraftMyStack, MatchMyTool, and CraftMyFlow, too.

How usage works

  • ✓ Searching the prompt library and reading the model catalog is always free.
  • ✓ The free tier includes a daily allowance of prompt refinements — no credit card.
  • ✓ When you hit the daily cap, your assistant tells you and links to upgrade — nothing fails silently.
  • ✓ Need more volume? Higher tiers are available via the Keelara API console.

Privacy

  • ✓ Prompts you send to refine are processed to produce the result and not used to train AI models.
  • ✓ Access is tied to your Keelara sign-in.
  • ✓ See our privacy policy for details.

Beyond Claude

PromptCueLab MCP follows the open Model Context Protocol, so the same URL works in any MCP-compatible client — ChatGPT (Apps/developer mode), Cursor, agent frameworks, and AWS Bedrock agent stacks. Point the client at the server URL above and authenticate with a Keelara account.

Troubleshooting

  • Tools look outdated or missing? Remove and re-add the connector — clients pin the tool list when you first connect.
  • "Daily limit reached"? You've used today's free refinements — they reset tomorrow, or upgrade for more.

Better prompts — without leaving the chat.
