The Origin
keysessions.ai is the product of two perspectives converging on the same problem. Giandomenico C. is a competitive road cyclist with over 30 years on the bike — an athlete who has lived through every era of training methodology, from handwritten logs to power meters and structured periodization. Ivan P. is an AI builder with an instinctive orientation toward data-driven systems — someone who sees training as an engineering problem with measurable inputs and optimizable outputs. Together, they asked a question that neither training apps nor generic AI tools could answer: what would a training platform look like if it was built by someone who actually trains?
The Problem We Saw
Most training tools fall into one of two categories. Static plans that are written before your first pedal stroke and break the moment life intervenes — a missed session, an unexpected rest day, a week of poor sleep. Or manual logging platforms that let you record everything but offer no structure, no adaptation, and no forward planning. The athlete is left to either follow a plan that no longer reflects reality, or become their own coach, analyst, and planner. Neither approach respects the complexity of structured training.
What We Built
keysessions.ai is a training operating system built around a single principle: every completed session should inform the next one. At its core is a deterministic periodization engine — not a language model guessing what looks right, but a structured algorithm that computes load targets, progression curves, and session distribution based on proven training science. It generates complete mesocycles tailored to your profile, your phase, your availability, and your physiological focus. When training goes differently than planned, the system recalculates. Not the next day — the next session.
The Role of AI
The periodization engine handles the logic. The AI handles the interpretation. A dedicated coach with full visibility of your training state delivers contextual briefings, analyzes your sessions, and answers your questions with data-grounded insight. It doesn't plan your training — the engine does. It doesn't make load decisions — the engine does. What the AI does is give you a coach's perspective on the data the engine produces. The separation is architectural and intentional: computational precision where it matters, intelligent interpretation where it adds value.
Who KSN Is For
keysessions.ai is built for advanced cyclists who train with structure and intent. Athletes who know their FTP, understand what TSS means, and want a system that respects their time and their data. Whether you ride road, gravel, mountain, or track — if you approach training with discipline and want a platform that does the same, KSN is built for you. It is not a fitness app. It is not a social platform. It is not a casual activity tracker. It is a training tool for people who take training seriously.
Join Us
keysessions.ai is in open beta, and we're building it in the open — you can follow every step forward on our roadmap. The periodization engine is live: you can generate complete mesocycles today, free. The rest of the platform is being released progressively over the coming weeks, and everything we ship during the beta stays free while the beta lasts. Sign up, put the engine through a real training block, and tell us where it can be sharper. If you want to help shape what lands next, we're in two places: Discord, where product decisions get debated and feedback is collected channel by channel, and Telegram, for riders who'd rather keep the conversation there. Both reach the same people. Use whichever you already have open.
