NUA vs ZEVEN (Lucy): A Personal Agent With Its Own App or a Coach Inside ChatGPT

NUA is the ZEVEN alternative for anyone who wants a personal AI agent for athletes that works today, in its own app or on WhatsApp, and also takes care of food and the weather. ZEVEN (with its coach Lucy) plans your cycling from inside assistants like ChatGPT or Claude, and it's in beta. NUA prepares and adapts your training, your food and your routes with your full context, warns you about the weather, sends you reminders and messages you before you ask; it learns from you every day and keeps operating for you even when you're not using it. Free trial, no commitment; price depends on your country (see pricing).

ZEVEN is a company (ZEVEN AG) that has built Lucy, an AI cycling coach. According to its website, it was built by engineers who race and UCI pro cyclists, and its idea is very close to NUA's: an agent that knows you, plans for you and speaks up before you ask. Today Lucy lives inside the assistants you already use (Claude, ChatGPT, Gemini, Grok and Perplexity); its own app is announced as the next step. It's in beta, with a waitlist. Everything we say here about ZEVEN comes from its website, checked in October 2026.

What ZEVEN does well: its strengths

ZEVEN is probably the rival closest to NUA's concept, and that says a lot in its favour. According to its website, Lucy plans backwards from your race or power goal, builds sessions and pushes them to your head unit and calendar, and suggests routes from your door that fit the day's training. It rebuilds the plan when a session moves, tracks your resting heart rate, HRV and sleep, and also supports the mental side (pre-race nerves, low-motivation days). Its examples show a proactive coach that reviews your overnight data and sends the plan before you wake up. And if you already use ChatGPT or Claude every day, having it right there is convenient. The list of integrations it announces is long, although its own website notes they'll come with the app.

ZEVEN's limitations: where NUA does better

The main difference is maturity and channel. ZEVEN is in beta with a waitlist, with no app of its own yet, and sending the plan to WhatsApp or Telegram is listed as "coming soon". NUA already works: it has trained more than 25,000 athletes, it has its own conversational app, and you use it on WhatsApp or Telegram from the first minute. ZEVEN's website also doesn't show features NUA does have: estimating calories and macros from a photo of your plate, warning you about the weather (rain, wind, heat) and adapting your ride, and sending you reminders. And its website only talks about cycling; NUA is cycling first, but also running and triathlon.

Why athletes look for a ZEVEN alternative

People who find ZEVEN are usually after exactly what it promises: an agent, not a plan app. But many don't want to join a waitlist or depend on keeping a general assistant open. They want something that messages them on their phone, in the channel they already use, and that also handles food and the weekend weather.

ZEVEN vs NUA: side-by-side comparison

NUA as a ZEVEN alternative: the personal agent you can use today

NUA and ZEVEN share the same core idea: an agent that operates for you. The difference is that NUA is already up and running and covers everything around your sport at once, in a conversation where you talk to it like you would to a coach. NUA:

• Prepares and adapts your training based on availability, real load, sleep, HRV and how you feel, with strength sessions with videos, and sends it to your device.
• Prepares your food: it estimates calories and macros from a photo of your plate and tells you what to eat for the session.
• Prepares your routes, taking the weather and the session you need to do into account, and warns you if rain, wind or heat is coming.
• Sends you reminders and warns you proactively, before you ask.
• Remembers your context and evolves with you, in the channel you already use: its app, WhatsApp or Telegram.

Start in a minute on WhatsApp, no download needed. When you want more, there's the NUA app (Android on Google Play; iOS very soon).

The difference between ZEVEN and NUA: a beta inside your AI or an agent on your phone

ZEVEN offers a cycling coach that lives inside a general assistant and is still in beta. NUA is a dedicated personal AI agent for athletes, available today in its app and on WhatsApp or Telegram, which on top of training and routes handles your food, the weather and your reminders. Same ambition, different stage of maturity. And NUA is transversal: one single agent for your whole sport, using the same context for everything and messaging you on your phone without you having to open another assistant.

ZEVEN or NUA? When ZEVEN is enough and when to look for an alternative

ZEVEN may be enough if you only ride, you already use ChatGPT or Claude every day, and you'd like to try a beta built by pro cyclists.

You should look for an alternative if you want something that works today, that messages you on your phone without opening another assistant, and that also helps with food, the weather and reminders. If you run or do triathlon as well as ride, NUA is also the better fit.

Conclusion: which is better, ZEVEN or NUA?

It depends on what you need: if you want to try a cycling coach inside your AI assistant and don't mind waiting for a beta, ZEVEN is enough; if you want a personal AI agent for athletes that already works, in its app or on WhatsApp, and also handles your food and the weather, NUA is the better choice. ZEVEN is a serious proposal, very close to what NUA does, and worth keeping an eye on. Today, the difference is that NUA already supports thousands of athletes every day.
