Trace
Read full descriptionHide full description
Press capture. Get it written up. Trace turns your conversations into context you keep: what was said, what was decided, and who promised what. Then it puts that context to work for you and your team. CAPTURE ANY CONVERSATION Tap Capture and talk. Trace works out what kind of conversation it was, a standup, an interview, a 1:1, a sales call, and writes it up to match. Pause whenever you need to and pick up where you left off. NEVER LOSE TRACK OF WHAT YOU PROMISED Trace picks up what you said you'd do and files it under the conversation it came from. Tick things off in To-dos, and see what everyone on your team has on their list. ASK ANYTHING Ask Trace across everything you've captured, or ask about one context or a whole Space right from its page. Answers quote the exact line and open the transcript right there. YOUR AGENT, ON YOUR TEAM Chat with the people in your workspace in Conversations. When you're busy, your agent can reply from your context and shows where the answer came from. Type @ to bring a person or an agent into the chat. KEEP PEOPLE IN THE LOOP Share a topic once and every context on it reaches them from then on. You approve each one before it goes out. WORKSPACES Keep personal and work apart. Create a workspace, invite your team, bring your existing contexts with you, and switch between workspaces in a tap. A HOME FOR EVERY CONVERSATION Group related contexts into Spaces: a client, a recurring 1:1, a hiring loop. CAPTURE WITHOUT FRICTION β’ One tap to start, and it keeps going if you switch apps β’ Live Activity timer in the Dynamic Island β’ Start a capture from the Action Button, Siri, or a notification β’ Edit any title or point in place WHO IT'S FOR Founders, PMs, engineers, consultants, recruiters, sales, anyone whose work depends on what got said, decided, or promised.
