Email and calendar
Reads, summarizes, drafts replies and schedules meetings.
Say it.
The agent does it.
A pocket device with a 4.3″ touchscreen and a microphone. You say the command, and a cloud agent handles your email, calendar and tasks. You approve anything it writes with one tap.
WaitingA clock and a mascot that floats gently. The agent is ready.
Assembled in PolandConcept visuals. We plan a working prototype for January 2027 and the Kickstarter launch for Q1 2027.

Why Crumbit
Yourphonecandoeverything.That’sexactlywhyitdistractsyou.
You take it out for one thing and end up doing three others. Crumbit One does one thing: it takes your voice command and hands it to an agent that works in the background and speaks up when it’s done.
No distractions
No browser, no feed, no app notifications. Just your command and its result.
Built for Europe
Agent features in phone assistants launch in select countries, often without the EU.
It acts, not just records
Many AI gadgets mostly record and summarize. Crumbit works in your email, calendar and documents.
How it works
Three steps from voice to finished task
01 · Listening
You speak
You press the button and dictate a command: “Tell Mark I’m moving the meeting to Thursday.”
02 · Working
The agent works
The agent does the task on a server. You don’t need to take out your phone or keep holding the device.
03 · You approve
You approve
Reading data happens without asking. You confirm anything that writes, such as sending an email, on the device screen.
04 · Music playing
Mascot, clock and voice wave
The screen shows what the agent is doing. No menus and no captions, just states you understand at a glance.
Try it
What one command looks like
Pick a command and watch what happens from voice to approval. Reading data goes ahead without asking, while anything that writes always waits for your tap.
Pick a command
A simulation that illustrates how it works. The data is sample data, and the device is still a prototype.
What the agent can do
One agent for everyday work
At launch it handles email, calendar and tasks. More skills arrive in updates after release.
Daily briefing
Each morning you know what’s on your calendar, what email is waiting and what needs doing.
Voice notes and tasks
You speak, and the agent turns it into notes and tasks with due dates.
Background tasks
The agent works while you do something else and speaks up when it’s done.
Searching your data
You ask about an email, file or conversation, and the agent searches what you connect.
Open service catalog (MCP)
You connect services with one tap in the phone app, using your usual login with the provider. You can add almost any tool, including your own.
Examples of services you can connect. Logos belong to their owners.
Photos and generations
Your phone stays in your pocket.
Say it, put it down, get back to your day. The agent speaks up when it’s done.

Who it’s for
For people who run things on their own
You handle email, calendar, quotes and reminders on the move, between meetings. Crumbit One takes those small jobs before they eat your day.

Comparison
Crumbit One vs Rabbit R1
Rabbit R1 showed that people want a pocket agent, and that a finished product matters more than promises. We’re doing it differently.

What Rabbit R1 taught us
01
We won’t ship an unfinished product
According to The Verge, R1 reached the market before it was ready. We launch the campaign only when the core scenario works reliably on the prototype.
02
Real tasks, not tricks
Reviewers wrote that R1 did nothing a phone couldn’t. Crumbit carries out tasks in your services and shows you the result.
03
Security from day one
Hard-coded API keys were reported in R1. With us, you approve every write on the device, and we build protection to the RED requirements and EN 18031.
Rabbit R1 data is based on public information from the maker and reviews; we will re-check it before the campaign starts.
Our commitment
A device that won’t vanish with its maker
Humane AI Pin stopped working when the company shut down in 2025. That’s why our promises go into the terms of sale.
2 years
Minimum service life
We guarantee at least 2 years of service from purchase, even if the company runs into trouble.
Your server
Then you can run it yourself
After that we release a server you can host yourself, so the device keeps working.
14 days
Return for any reason
Not for you? Send it back. After that the warranty in our terms applies.

Any language, Polish included. The microphone and the agent understand commands regardless of language.
Which services can I connect?
At launch the agent handles email, calendar and tasks. You connect services with one tap in the phone app, using your usual login with the provider, in an open MCP catalog. You can also add your own tools.
