The companion tool Claude Code deserves.
Claude Code is powerful. But without a plan, it can go off the rails. SpecThis gives you a UI to write, review, and track specs—so Claude always knows what to build.
Free for a limited time. No credit card. 2-minute setup.
Claude Code is fast. Sometimes too fast.
You ask Claude Code to add a feature. It starts writing code immediately. Twenty files later, you realize it went in a completely different direction than you wanted.
The fix isn't to slow Claude down—it's to align it first. Anthropic's own best practices guide recommends asking Claude to plan before it codes.
But where does that plan live? In chat history that scrolls away? In a markdown file you'll forget about?
A real UI for Claude Code specs
SpecThis is a dedicated app for writing and reviewing development specs. Claude Code connects to it via MCP—the same protocol that powers Claude's tool integrations.
Instead of plans getting lost in your terminal, they live in a structured UI where you can review scope, acceptance criteria, constraints, and planned file changes—all before Claude writes a single line of code.
Add SpecThis MCP in Claude Code
Point Claude Code at the SpecThis HTTP MCP endpoint. Agents get plan and repository tools — scans still run in the SpecThis UI, CLI, or GitHub.
claude mcp add --transport http spec-this https://app.specthis.ai/api/mcp --scope userSet up in 2 minutes
claude mcp add --transport http spec-this https://app.specthis.ai/api/mcp --scope user
You: Create a spec in SpecThis for adding dark mode to the app
Make Claude Code even better.
Stop hoping Claude builds what you want. Start knowing. Free for a limited time.
