World's First AI E-Ink Hub for Smartphone
You don't have to give up your phone.
A snap-on E-Ink hub for your iPhone. One press to capture meetings, interviews, and lectures without unlocking. AI summaries in 100+ languages, on a glanceable, eye-friendly display with its own battery.
The case
Reetle is a separate piece of hardware for the things your phone keeps interrupting. It sits on the back, it records when you press once, and it shows you the three things you said you'd do today. It is not a phone replacement, not a translation device, and not a magic wand. The screen is calm so the work stays loud.

languages, speaker-attributed
Recorded. Not interrupted.
The capture layer your second brain was missing.
Voice in, structured markdown out. Reetle lives on the side of your phone so the friction between thought and capture drops to one press. Your existing notes app does the rest.
physical button, no unlock needed
Thought first. Press once. Filed.
15 hours of lectures. Transcribed. Searchable.
One charge gets you through a week of classes. Capture the whole lecture, get the summary before you walk out, search the archive when the exam shows up.

Marginalia
It sits where my notepad used to. The capture happens once, the summary writes itself, the meeting stays a meeting.
Marginalia. Reviewer to confirm.
Recorded a four-hour interview without my phone overheating. That was the test. It passed.

On the record
What Reetle isn't.
Not a phone replacement.
Reetle adds a screen, a button, and a battery. Your iPhone is still your iPhone.
Not a translation device.
It transcribes 100+ languages and summarises in the one you read. It does not interpret.
AI summaries are not human transcription.
For legal or medical use, treat the transcript as a draft. A human still owns the record.

Editor's notes
Reetle records about 8 hours per phone charge. With the case battery, you get up to 15 hours. The hub draws from its own cell, so an active recording does not drain your phone.
Reetle snaps onto iPhone 14, 15, and 16 (Pro and standard). Earlier iPhones are not supported in Sprint 1; a USB-C adapter for older phones is on the roadmap.
Over 100 languages, including code-switching between two in the same recording. The summary comes back in the language you set, regardless of what was spoken.
Audio is captured on the hub and processed in our EU data centre to produce the transcript and summary. You can delete any recording from the hub or your account at any time. We do not use your audio to train models. Full details on the privacy page.
Day one: EU, UK, Switzerland, Norway. Day two (when stock allows): US and Canada. Tracked shipping with a delivery estimate at checkout.
2 years against manufacturing defects, EU statutory minimum. Reetle hubs are MIL-STD-810H rated; warranty does not cover misuse outside that envelope. Warranty page has the specifics.
Card is authorised at pre-order, charged when the unit ships. If we miss the shipping window we communicated, the authorisation is released and you can cancel at any time before charge.
30 days from delivery, no questions asked. Reetle covers return shipping in the EU; outside the EU we cover one of the two legs. The refund page lays out the full process.
Waitlist signups get the date the day pre-orders open. Pre-order customers get the date in the order confirmation. We don't post a date here because shipping depends on certification, and the cert clears when it clears.
The Reetle hub, a snap-on case for your iPhone model, USB-C charging cable, quick-start card, and a sticker for the laptop you no longer need at the meeting.
