Hark Pro is an operating system for your life, built to think ahead, and help you with real, practical things. By combining advanced memory and the ability to use a computer in the cloud, Hark understands the context of your life and can take care of things across the web. No agents or subscriptions required. Hark can log in to OpenTable and make a reservation for you. But it’s also smart enough to reference your calendar for an open time, recall your favorite spots for openings, note your friend’s food allergies in the reservation, and even create a button to reserve an Uber to get there that night. Use Hark to order groceries. Return products. Manage your schedule. Build mini apps. And track complicated projects, integrating Google Docs and Slack messages, mindlessly. Hark is a simple chat app with powerful capabilities - freeing your time to spend away from screens. Proactive thinking Hark looks ahead. Book a movie on Hark, and Hark won’t just buy the ticket and add it to your calendar. It’ll scope the parking situation ahead of time, and offer to reserve you a spot before they fill up. Hark thinks creatively to remove friction across your life. Use the web with Handoff Just type “deliver me pizza” to hand off the task to Hark. It will hunt for the best local pizzarias, go on their websites, read their menus, and order you one for delivery via DoorDash (with your consent and favorite toppings, of course). Hark securely manages your logins to hundreds of sites including Target, Amazon, and LinkedIn so it can handle tasks from start to finish. Hark can also fill out web forms for you, writing multiple services to get quotes on a move or renovation. It can dig through webpages to find dentists who actually take your insurance - and email them for you to ask if it's unclear. It can plan your new wardrobe, then present it on a custom website built just for you. Manage your personal and professional life With Email and Slack integration, Hark can keep track of your most important messages, build your daily schedule, balance your calendar, and summarize dozens of discussions across your workplace into just the things that you need to know. Follow long term tasks with Projects Hark can manage your life in one, long-running chat. But sometimes you want to start with a blank slate. Projects are dedicated threads for longer term work. They focus a single topic, and related files, in one place that you can visit again and again over time. Build your own Panels Never learn to code. Hark can generate tiny bits of software called Panels - ranging from exercise trackers to media players - that live right inside the Hark app. All you do is prompt. You can even ask your Panels questions to dig deeper into their data, unlocking even more from services you already use like Strava, Spotify, and Venmo. Solve it with a button press Notifications give you work. Hark’s Action Buttons provide solutions. Hark’s one-line summaries highlight the most important things you need to do next. Just press a button to “pay” a bill, “RSVP” to an event, or “review” an insurance claim. Do everything else you expect an assistant to do Researching questions. Analyzing PDFs. Yes, even telling you the weather. Hark offers all of the same baseline services offered by other leading AI labs, too. Security and privacy Your data is your own. Hark will never sell your data or serve you ads. We also never see your most private information, like stored passwords or credit card numbers, which are always encrypted in storage and in transit.
