Most AI benchmarks test models in controlled environments. Agent Mode tests them on complex tasks to get more work done. Run autonomous agents that browse, research, code, use files, and complete multi-step workflows from a single prompt. Then watch each workflow unfold step by step. Every run contributes to the Agent Arena Leaderboard, ranking frontier models by real-world agentic performance.

Most AI apps launch on someone else’s model and stay there forever. Empromptu AI turns live AI features into custom models you own. As your app runs, Empromptu AI captures real-world usage, human corrections, and edge cases from live AI workflows, then uses that signal to train a custom model you own. Improve accuracy, lower inference costs, and stop depending forever on rented intelligence from the same providers moving into your category.

uselink turns any HTML or Markdown into a clean link you control. paste a doc, get a url under your handle, decide who can read and who can comment. readers reply in threads with no account, which Google Docs and Notion can't do. interactive HTML actually runs. add a password, an expiry, or a view limit, and keep every version. new this launch: a visual editor to edit live pages with no code, and an MCP server so Claude, Cursor, or n8n can publish for you.
