I’ve been working on a macOS app called **Portability**.

The problem I kept running into was that my AI work was trapped inside whichever tool I started with.

I might be halfway through building something in Claude Code, hit a usage limit, and want to continue in Codex. But Codex has no idea what Claude already tried, which decisions were made, what failed, or what constraints we were working with.

The usual solution is to copy and paste everything, write a long summary prompt, or start again.

Portability is designed to remove that friction.

It automatically saves your prompts, chat logs and agent outputs locally on your Mac, so you can:

• Continue an existing session in another AI tool without re-explaining the project  
• Switch models when you hit a usage limit or want a second opinion  
• Let Claude Code and Codex see what the other agent has already done  
• Keep a private, searchable archive of your AI-assisted work  
• Export your sessions into notes, memory tools or other systems  


The idea is that your work should belong to you, not be locked inside one model or provider.

It’s currently free to download for macOS, with versions for both Apple Silicon and Intel Macs:

I’d really appreciate feedback from people here who regularly use more than one AI coding tool.

What would Portability need to do for it to become genuinely useful in your workflow?
