Why this is different
No app sees the full picture. Retrace connects the dots.
Your life doesn't happen on one platform. A single decision might span a ChatGPT brainstorm, a WhatsApp conversation with a friend, and an Obsidian note where you planned next steps. Retrace is the only place where all three connect.
Across platforms
You explored a career change in Claude, vented about it on WhatsApp, and journaled in Obsidian. Retrace links all three. Search for the topic and see every conversation, every platform, on one timeline.
Across people
The same topic discussed with three different people reveals three different perspectives. Retrace surfaces who you talked to about what, and when the conversation shifted.
Across time
An idea you mentioned once in January, forgot, then brought up again in April. Retrace sees the thread even when you don't. Topics, people, and decisions become visible arcs, not isolated fragments.
You're sitting on years of insight.
It's locked in platforms you don't control.
Meta has your Messenger and Instagram archives since 2010. Google has your Keep notes, your calendar, your search history. OpenAI has every question you ever asked ChatGPT. Your most personal thinking lives on their servers, for their benefit, not yours.
Retrace helps you take it back. Export your data, import it locally, and for the first time see the full picture. Browse years of conversations in one place. Rediscover interactions you forgot, decisions you made, people who shaped your thinking. Your conversations become your journal, your timeline, your searchable memory.
Your data. Your machine. No exceptions.
