The Diver app brings the original Stanford University Digital Interactive Video Exploration and Reflection (DIVER) project* to Apple's iPad and iPhone. Features of the new app include: • A touch interface implementation of Diver's "guided-noticing" spatial and temporal point-of-view video referencing; users can move & resize the Diver guided-noticing rectangle via iOS's familiar touch interface. • An updated implementation of Diver's networked/Internet sharing of point-of-view video clips– allowing for a) dives** directly on your own or anyone else's videos, and b) easy social sharing of dive clips. For more info about the app read the latest notes/documentation: https://app.diver.video/howto/diver_howto_442_01.php Please also see our EULA (end-user-licensing-agreement): https://app.diver.video/eula * For more info about the original Stanford University Diver project visit: https://diver.stanford.edu ** "Dives" are time/space referenced video clips made by (temporally) selecting sub-portions of a video and (spatially) highlighting areas of the video's frame.

Most people think great communicators are just born that way. They're not. Conversation is a trainable skill — and Theseus is the coach that trains it. Theseus is an AI conversation coach that pays attention to HOW you communicate — the hedging, the rambling, the joke you crack instead of answering, the follow-up question you never ask. It tells you what it sees, gives you something concrete to work on, and runs live practice reps until the skill sticks. HOW IT WORKS - Talk to your coach like a sharp friend who happens to be brilliant at people. - It reads how you actually communicate — not what you claim — and reflects it back, specifically. - It builds a communication-skill profile across 16 dimensions in four areas: Conversational Foundations (listening, clarity, curiosity, presence), Social Dynamics (assertiveness, warmth, storytelling, humor), Hard Conversations (conflict, boundaries, feedback, staying regulated), and Connection Patterns (vulnerability, reading the room, repair, consistency). - Every session leaves you with one clear insight and one small rep to try in real life. ROLEPLAY — SPAR LIVE Stuck on a conversation you keep avoiding? Negotiating a deal, setting a boundary, a hard talk with your partner? Run it as a roleplay. Your coach plays the other person — a client who stonewalls, a date who gives short answers — then steps out and debriefs what worked and what to adjust. Practice the hard part before it counts. THE YARD — DAILY SKILL DRILLS Quick games that sharpen the mechanics of communication: From snappy twisters, to objection sparring - try our daily curated games to hone your skills. You don't get better at conversation by reading about it. You get better by practicing — with a coach who's always paying attention. Start your first rep today.
