Start fresh. Keep your progress.
Open a focused thread after a long investigation or a change of direction. Automatic capture brings relevant findings and task checkpoints with you.
Choose how your agent picks up the work
Your next session should start with the decisions you made, what you learned, and what comes next. Crosshead brings that working context to Claude Code and Codex.
Start with free working memory. Add paid hosted operations when you need them. See pricing.
Crosshead carries the goal, decisions and next steps into the session where you want to work.
Open a focused thread after a long investigation or a change of direction. Automatic capture brings relevant findings and task checkpoints with you.
Move between Claude Code and Codex with the working context ready for the next session.
Inspect saved findings and signed handoffs. Task checkpoints stay available alongside the chat, including after compaction.
Native resume reopens a saved conversation in the same tool. When you want a fresh thread or a switch between Claude Code and Codex, Crosshead brings relevant working context with you. When to resume or start fresh.
Crosshead completed every tested workflow at lower API cost than each tested handoff or memory method. The next agent gets the context to finish the work.
Than claude-mem, with both completing all 16 workflows.
Than Cairntir, with both completing all 16 workflows.
Keep the task moving without writing your own handoff. Crosshead also cost 13.7% less than the update-only handoff control.
| Method | Workflows completed | Total API cost |
|---|---|---|
| Crosshead | 16/16 | $1.62 |
| Agent-written handoff · updated when needed | 16/16 | $1.88 |
| Structured handoff + saved sources | 16/16 | $2.22 |
| Cairntir | 16/16 | $4.92 |
| claude-mem | 16/16 | $4.29 |
| Supermemory Local · configured | 11/16 | $2.89 |
In the separate Claude-only comparison, both methods completed 8/8 fresh-session workflows. Crosshead cost $0.91; auto memory cost $1.21. Auto memory carries saved notes into a fresh session; resuming an existing conversation is a different workflow.
Eight synthetic task families created by Crosshead, using GPT-6.1 Sol and Claude Opus 5.5. One run per task and tool pairing. Costs include coding and background model calls; subscriptions, service fees, local compute and operator time are excluded.
