You keep talking.
It keeps saving.
As your conversation grows, your local copy keeps up.
AUTOMATIC LOCAL BACKUP FOR CHATGPT
Open a chat. Keep working.
ThreadHarbor quietly keeps a local copy up to date while you talk.
Leave the conversation. Rename it. Close the tab.
Your latest complete copy stays on your computer.
No card required. Manual backup stays free forever.
Let's keep working on the idea.
The next step is to make the first version simple enough to use every day.
No extra step. No extra thought.
WHILE YOU GET ON WITH YOUR DAY
As your conversation grows, your local copy keeps up.
Switch chats or leave the page. ThreadHarbor saves the latest changes.
The local backup follows the conversation's title, without a mess of duplicate old names.
THE DIFFERENCE THAT MATTERS
If a page only gives us half the conversation, that partial copy won't overwrite the more complete backup you already have.
