ChatGPT is great at work. This isn't work.
If you've ever typed something personal into a work tool and felt a bit strange about it, this page is for you.
One huge difference
Rhythm is a personal AI for thinking things through, built for private reflection. ChatGPT and Claude are general purpose assistants built to complete tasks for anyone. They're genuinely good at that. The conversations that change how you feel need something different: a voice you've set yourself, memory that carries, and a space that isn't also where you write your emails.
Different tools, built for different conversations
We're not here to tell you ChatGPT is bad. It's just focused on something else.
| Dimension | Rhythm | General AI assistants |
|---|---|---|
| Built for | Your inner life | Your to-do list |
| Voice | You set how it sounds, how much it says, and how hard it pushes back | One general purpose assistant tone or a couple of preset options for you to choose between |
| Memory | Built to hold your context: the people, the patterns, the thing you said three weeks ago | Built for task continuity |
| Optimizes for | Hearing yourself more clearly | Finishing the task |
| Where it lives | Its own app, on purpose | The same window as your job |
| Business model | A subscription. No ads, no data sales. | Varies |
An assistant answers. Rhythm remembers.
Tell Rhythm about the hard conversation with your sister. Three weeks later it still knows who she is, what happened, and what you were worried about.
That's the difference between a chat and a thread. You never start from zero, which is what lets reflection actually go somewhere: patterns surface, and Rhythm can point at them because it was there the first four times.
It's not built to agree with you
Most AI is trained to be agreeable, and it shows. Ask whether you overreacted and you'll usually get told you didn't.
Rhythm goes as blunt as you want it to. If you set it to push back, it pushes back, because feeling better sometimes means hearing the thing you'd rather not. Agreeable is easy. Useful is the point.
Some thoughts don't belong in a work tool
Your work AI history sits next to your meeting notes and your performance review. That's fine for drafting emails, where your employer owns the app.
Rhythm is its own space: stored so no human can read it, lockable with Face ID, and deletable from a button in settings. Nothing you write is sold or shared, and when Rhythm asks a model for a reply, your name and account don't go with it. More on how that works
You don't have to build it yourself
Plenty of people have already tried to turn a general assistant into this, with custom instructions and saved context and a project folder. It works for a while. Then it drifts, and you're maintaining a system instead of using one.
Rhythm starts where that ended. See how the five settings work

Frequently asked questions
How is Rhythm different from ChatGPT?
Rhythm is a personal AI for thinking things through, built for private reflection. ChatGPT is a general purpose assistant built to complete tasks. In practice: you set how Rhythm talks to you across five settings, it remembers what you've told it between conversations, and it lives separately from the tool you use for work.
What about Claude or other AI assistants?
Same distinction. They're general purpose assistants aimed at tasks and available to everyone in the same voice. Rhythm is one space, tuned by one person, that remembers that person.
Can I use both?
Most Rhythm users do. Work tools for work, Rhythm for the rest.
Is Rhythm just ChatGPT with a different interface?
No. Rhythm runs on models from OpenAI and Anthropic, the same way most AI products run on models they didn't build. What Rhythm adds is the tuning, the memory, the privacy architecture, and the rules for how it behaves when a conversation gets heavy.
