OUR LINE OF THOUGHT Did you know that children multiply by 10 our capacity to generate ideas to solve problems? Are you one of those who know or suspect that this is not a coincidence? Have you noticed that the traditional education system not only makes us learn the same thing, but that we think in the same way? What is really crucial is, what will we lose and what will ours lose in those 100+ ideas that are left unformulated every moment as we grow up? What opportunities will continue to be wasted? How many of those ideas will be the EUREKA that will change our lives? And more importantly, how many times will we stop being ourselves by repressing those ideas? The funny thing is that the main difference between a great idea and a conventional one is the route we follow when thinking, the way we connect the information and the type of thinking we use. To begin to uncover this creative and genius potential that we all possess, LATERAL has gone back to the basics, and from the simple game it connects you with the self-knowledge of these innate skills and types of thinking, the basis for creating. LATERAL allows you to be more fluid and have those transformative abilities so valued and scarce in today's academic and professional world. LATERAL knows the way, in more than 4 years of development, to expand your IDEAS and proposes you to curiosity, experiment, discover and self-magnify the creative and solutionist GENIUS that has always been inside you. START FOR FREE AND WITHOUT PRESSURE Try it, it has a FREEMIUM system by number of exercises and not by limit of days because LATERAL first of all respects your own speed of exploration. FUNDAMENTAL VERTEXES We have 3 fundamental vertexes that are connected through a journey of self-discovery on the player's thinking. He will be able to know, with respect to other LATERAL players, what his thoughts are like: divergent, lateral, flexible and expressive. He will also have access to see what thinking skills he stimulates when he is inspired, he will get scores for goal accomplishment and solving ability in the games, and he will be able to keep track of all his creations and observe how they become more and more fluid, effective and distinctive.

About

Critical Friend

Read full description

Critical Friend is a thinking companion for ages 7โ€“14. Powered by AI, it uses the Socratic method to ask the questions that help children think more deeply, about their homework, about the news, about the world around them. A conversation that goes somewhere Every pathway starts with a warm, curious question and builds into a genuine exchange of ideas. Critical Friend never lectures and never gives the answer. Instead, it listens, challenges, and helps your child find their own conclusions. My Thinking documents After a conversation, children can create a My Thinking document โ€” a beautifully designed PDF that captures their thinking journey. Add a title, a cover photo, photos of completed work, and share it straight to a teacher or keep it as a record of learning. It's the kind of thing you'll want to stick on the fridge. Seven pathways to deeper thinking โ€” Homework: talk through completed work and understand it more deeply โ€” News: make sense of the world and develop media literacy โ€” Experience: reflect on a trip, event or moment that mattered โ€” Activity: design a game or activity around something you love โ€” Reading: explore a book chapter by chapter โ€” Image explore: photograph something interesting and follow the ideas wherever they lead โ€” Daily challenge: a fresh thinking prompt every day Built for children, trusted by parents, loved by teachers Critical Friend is designed with child safety at the centre. There are no ads, no social features, and no data sharing. Parents have their own dashboard to review every conversation, manage profiles, and set limits. Flexible pricing Five free conversations per child per month โ€” enough to explore. Upgrade to Premium for unlimited thinking across up to five children, or add a conversation top-up whenever you need it. https://www.criticalfriend.app/terms https://www.criticalfriend.app/privacy-policy
