Appointments, birthdays, the plumber's number, when the filter needs changing — text her whatever you don't want to carry around in your head, and ask for it whenever you need it back.
Text it once. Ask for it back anytime.
Not hypotheticals. These are the kinds of texts Hazel gets on a random Tuesday.
“Remind me to put the recycling out Thursday night.”
“My granddaughter's recital is the 14th at 4pm.”
“What's the number for my eye doctor?”
“What was that soup recipe I saved last winter?”
“The Wi-Fi password is on the fridge, right?”
“Remind me to call my sister on her birthday, the 22nd.”
“Save this: the plumber's number is 555-0148.”
“What time is my dentist appointment tomorrow?”
“Is it supposed to rain this weekend? I want to work in the garden.”
No app to open. No account to create. Just text Hazel anything you want to remember — and ask for it back anytime.

On day one, Hazel knows nothing. By month three, she knows your family's birthdays, your doctors, your favorite recipes, and every little thing you've asked her to remember. All from casual texts you barely remember sending.
“Text Hazel anything you want to remember. She keeps it, and gives it back exactly when you ask.”
Just a text message. Nothing to download, nothing to configure.
Try it now — text HazelYou never have to check in with Hazel. Any normal text keeps things going. Here's exactly what happens if she doesn't hear from you for a while — nothing more, nothing hidden.
Texting Hazel about anything — a reminder, a question, just talking — resets the clock. There's nothing to remember to do.
After a day and a half of quiet, Hazel checks in herself — a simple, low-key text. A reply is all it takes.
After two days of quiet, Hazel reaches out to someone on your own contact list — starting with whoever's closest, so someone can actually check on you.
Anyone on your list has to agree first. And you can turn the whole thing off anytime — just text MUTE, no explanation needed.
Hazel is not an emergency service. If something is seriously wrong, call 911 or an emergency contact directly. Her messages are never urgent alerts — just a plain ask, like “could you stop by or give them a call?”
An appointment, a birthday, a phone number — say it the way you'd tell a friend.
No forms, no folders. She quietly holds onto it until you need it.
A week later or a year later — she'll have it.
Hazel is reminders, memory, and a quiet safety net, all over SMS. No app, no account. Just text her the way you'd text anyone else.
Just text the number above — (929) 828-4141. Hazel introduces herself right away and you can start asking her to remember things immediately. No forms, no downloads, nothing to set up first.
No. Hazel works over regular text messages. Any phone that can send and receive texts works.
Not at all. Talk to Hazel exactly like you'd talk to a person — you don't need perfect spelling or the right words. Just say what you mean and she'll figure it out.
No, not by default. Your conversation with Hazel belongs to you — she never shares it with anyone automatically. If you ever want a family member to see a simple status, you can turn that on yourself, and text WHO SEES THIS anytime to see exactly who has access and remove them.
No. Hazel is not 911 and not a medical alert system. If there's a real emergency, always call 911 or your emergency contact directly. Her only job is reminders, company, and a quiet check if she hasn't heard from you in a while.
Nothing, right away — any ordinary text to Hazel resets the clock, so there's no daily ritual to keep up with. If she genuinely hasn't heard from you in a day and a half, she'll check in herself. If that goes unanswered for another day, she'll reach out to someone on your own contact list.
You tell her, the same way you'd tell her anything else. Text something like “If you don't hear from me, check in with my daughter Sam — her number is 555-0199,” and she'll save it. You can add or change this anytime.
Yes. Text MUTE anytime and Hazel stops — no explanation needed.
Yes — a real phone number is always available if you'd rather talk to someone than text.
Hazel is free to use. Standard text messaging rates from your phone carrier may apply.
Reply STOP at any time to stop all texts, or HELP if you need assistance.
This thread belongs to you. By default, no one else can read it — not a summary, not a transcript. Nothing.
Not a summary. Not a transcript. Nothing — unless you say so.
If you want family to see a simple status, you can turn that on. It's never automatic — not for anyone, unless you say so.
Text WHO SEES THIS and Hazel lists exactly who can see your status. Revoke anyone with a single text.
Switch back to fully private anytime. It takes effect immediately.
