Questions & Answers

As answered by people managing Supermemory and Crosshead.

Why should a person choose your product over its competitors?

Crosshead's answer:

Choose Crosshead if you regularly start fresh coding sessions, return to projects after a break, or switch between Claude Code and Codex. It helps the next session start with decisions you have already made and approaches you have already tried, reducing the need to write a recap or explain the same requirements again.

You can start with free working memory, inspect what your agent remembers, and add prepaid credits for optional long-term memory, search and archives. There are no subscription or seat fees. The CLI, daemon, adapters and hooks are open source under Apache-2.0.

What makes your product unique?

Crosshead's answer:

Crosshead combines automatic working-memory capture with continuity between Claude Code and Codex. It saves recent requests, decisions, corrections and next steps through the tools' lifecycle hooks, then brings that context into a fresh session in the same repository.

Each project keeps its own working memory, and each agent has its own identity. Signed handoffs and an inspectable command-line interface help you understand what is being carried forward. Recent working memory is free; deeper search and archive operations are available through prepaid credits.

How would you describe the primary audience of your product?

Crosshead's answer:

Developers who use Claude Code or Codex for ongoing projects, particularly people working across several sessions, repositories or coding tools. This includes independent developers, consultants and small engineering teams. Teams running multiple agents can also share credits and set individual spending limits.

What's the story behind your product?

Crosshead's answer:

Crosshead is built by FriendMachine Labs, LLC, a Michigan company working on persistent AI operators, useful software and research. It addresses a recurring problem in agent-assisted development: decisions and discoveries can get stranded in a chat, even though the project continues.

The goal is to let useful progress carry forward when a session ends or the coding tool changes. FriendMachine publishes continuity benchmarks with their methods, results and limitations, alongside the open-source client.

Which are the primary technologies used for building your product?

Crosshead's answer:

Crosshead is built primarily with TypeScript and Node.js. The hosted API uses Fastify, PostgreSQL with pgvector for vector search, and Redis. Infrastructure runs on Google Cloud, including Cloud Run, Cloud SQL and Cloud Storage.

The local CLI and daemon connect to Claude Code and Codex through lifecycle hooks. Agent authentication and signed handoffs use Nostr-compatible secp256k1 keypairs.
