AI Agents Directory: the agent tools actually worth trying.

Estimate what an AI model costs per request, per day and per month. Compare GPT, Claude, Gemini and Grok API prices side by side.

Paste text and get an instant estimate of how many tokens it uses, plus words, characters and what it costs as input.

Fill in a few fields and get a clear, well-structured prompt for ChatGPT, Claude, Gemini or Grok. Copy it in one click.

Generate starter config files and system prompts for Claude Code, Codex, Cursor, CrewAI, LangChain and the OpenAI Agents SDK.

Add MCP servers once and get ready-to-paste config for Claude Desktop, Claude Code, Cursor and VS Code.

Fill in your site's name, summary and key links and get a valid llms.txt file that AI assistants can read.

Define a function once and export the tool-calling JSON schema for OpenAI, Anthropic Claude and Google Gemini.

Estimate what one multi-step agent task costs: steps, tool results, growing context, caching and retries, then per day and per month across 33 models.

Write your project rules once and export AGENTS.md, CLAUDE.md, GEMINI.md, Cursor rules and GitHub Copilot instructions.

Pick your goal, skill level and budget and get a recommended AI agent stack from the AgentScout directory, with a shareable stack card.

Paste a system prompt and get a score out of 10 with checks for role, task, output format, rules, conflicts, vague wording and prompt-injection defenses.

See how much of your model's context window the system prompt, tools, documents, history and output reserve use, as one clear bar.

Pick a license (MIT, Apache, GPL, AGPL, ELv2, BSL and more) and see if you can use it commercially, self-host it or offer it as a service.

Compare self-hosting an open-source AI agent with paying for a hosted tool over 12 to 36 months, with the break-even month.

Tick the apps you use, like GitHub, Slack, Notion or Postgres, and find matching MCP servers in the AgentScout directory.

Paste a JSON Schema and a model's output to see if it passes, with exact error paths and OpenAI strict-mode checks.

Pick 2 or 3 AI tools from the directory and get a side-by-side comparison and a shareable image card.

Enter a website and see how ready it is for AI agents and AI search: llms.txt, robots.txt AI crawler rules, sitemap, structured data, MCP and agent files.
