Subtext (Claude)

**Subtext is session replay built for agents instead of humans.** Connect it and your Claude agents can open real production sessions and investigate them directly—no scrubbing a timeline, no video to watch. Learn more at https://subtext.fullstory.com/docs/introduction Hand your agent a Subtext link from wherever it already looks—a Sentry issue, a Linear ticket, a support thread, a PR—and it jumps to the right moment, inspects screenshots and accessibility trees, diffs DOM state, and reads console and network activity to find the root cause. Then it files the fix or hands you the finding. You review the answer, not the replay. What your agent gets: * **Session tools it calls directly**: open a session, jump to a moment, inspect and compare state—purpose-built so agents traverse dense session data efficiently, with fewer tokens than pointing a general agent at raw replay. * **Best-in-class capture from Fullstory**: Fullcapture behavior, pixel-perfect screenshots on demand, DOM diffs, and windowed console and network context. * **Privacy built for production**: precision tools for agents to mask or exclude sensitive fields, plus agent-friendly DLP scanning tools over MCP. * **Cost-effective**: Capture every session without sampling and never miss a critical user experience or bug report. Agents review the ones that matter most. Works with Claude Code or any MCP-compatible agent. Code-first install, self-serve signup, generous free tier, usage-based pricing. Bring your own agent harness—Subtext is the session context it was missing. Session replay used to be something humans watched. Now it's evidence your agents act on.
