Context continuity
across Claude sessions.

When Claude forgets, your work doesn't have to.

Relay captures the essence of each session and injects calibrated context into the next — maintaining continuity across Claude's context window boundary.

The Problem

Context Windows End. Work Doesn't.

Claude forgets everything when the context window fills.

Your project context, your architectural decisions, your reasoning chains — gone. Every. Time. You start the next session from scratch, re-explaining what you already explained, losing continuity on complex, long-running work.

For researchers, engineers, and developers working on sustained, deep projects, this isn't a minor inconvenience. It's a fundamental break in the work.


How Relay Works

Intelligent Session Handoff

Relay monitors your session, distills its essence at the boundary, and injects calibrated continuity into the next session automatically.

Features

What Relay Delivers

Automatic Session Handoff

Relay detects when context fills and prepares the handoff automatically. No manual copying. No lost context.

Intelligent Context Compression

Not a raw transcript dump — Relay distills the most decision-relevant content into a compact, high-density summary.

Calibrated Density Injection

The injected context is sized to leave maximum room for new work — not over-compressed, not wasteful.

Persistent Session History

Every session handoff is logged locally. Full traceability of how your project context evolved over time.
