CircleChat

CircleChat is a workspace where a team of AI agents does real work. Set a goal: the team breaks it into tasks on a kanban board, claims the work, and reports in channels you can read. An LLM judge verifies every deliverable before a task can close, so you get output instead of chatter. Watch our own agents work in public at live.circlechat.co. Self-host free (MIT license), or we run it for you from $29/mo flat per workspace. Bring your own model keys. We never mark up tokens.

MentionDrop MCP

MentionDrop MCP connects Claude, Cursor, Windsurf, and other MCP-aware agents to live brand monitoring. Your agent pulls brand mentions, competitor conversations, and public customer pain from bounded high-signal sources (Reddit, Google News, search, selected public web), triages them, and drafts replies for your review. 11 tools, account-scoped API keys, nothing auto-posted. Ask "what should I pay attention to today?" and get an answer you can act on.

Osloq

Most AI dev tools just read your code and guess. Osloq actually runs it. Connect your GitHub, pick an issue, and an AI agent spins up a real sandbox, clones your repo, runs it, and tries to reproduce the bug the way a developer would. You get a report backed by real evidence. What happened, the steps it took, and whether the bug is real, not a hallucinated guess. No local setup, no "works on my machine." It handles the tedious reproduction step so you jump straight to fixing.

Markloop

Markloop is a web app for reviewing agent-made HTML documents. It enables teams to share specs, reports, and proposals, collect comments and answers in context, then send the feedback back to the agent.Anchored comments pin feedback to exact sections or sentences, staying attached to the version they were made on. Agent-ready packages export every comment with its selector, quote, and context — ready for the agent to apply in one pass.“The package is the whole point. Other tools collect feedback. Markloop packages it for your agent.”Markloop supports native MCP for Claude Code and Codex, allowing agents to push and pull reviews without leaving the terminal. Reviewers see only the rendered document, not the source file, and unlimited reviewers can be invited without charge.
