Open Source & Free Forever

AI that actually
works for you.

Not another chatbot. An AI assistant that manages your email, organizes your calendar, plans your trips, remembers what matters to you, and handles the busywork — so you can focus on what counts. No subscriptions. No complexity. Just results.

Runs on anything — from a $5 Raspberry Pi to your Mac, PC, or the cloud

Most AI just talks. This one works.

You've tried chatbots. They answer questions but don't do anything. Crayfish is different — it takes action on your behalf, 24/7.

Typical AI
  • Tells you about emails
  • Suggests calendar tools
  • Requires constant prompting
  • Lives in a browser tab
  • Fixed capabilities, take it or leave it
  • Monthly subscription fees
  • Forgets everything between conversations
  • Treats you like a stranger every time
Crayfish
  • Sends and manages your emails
  • Schedules meetings for you
  • Proactively keeps you on track
  • Works in the background, always on
  • Learns new skills — travel, family, productivity, and more
  • Free and open source forever
  • Remembers what you tell it — always
  • Gets to know you personally over time

What can your AI do?

Talk to it naturally. It handles the rest.

Email

"Send Mom a message that I'll call her tomorrow."

"Do I have any urgent emails?"

"What did the team say about Friday?"

Calendar

"What's my schedule tomorrow?"

"Book lunch with Alex on Friday at noon."

"Move my 3pm to next week."

Memory

"Remember, I'm allergic to shellfish."

It recalls facts about you automatically.

No repeating yourself. Ever.

Knows You

Learns your name, job, and preferences naturally.

The more you talk, the more personal it gets.

Like an assistant who actually pays attention.

Reminders

Proactive check-ins throughout your day.

"Meeting in 15 minutes."

"3 emails need your attention."

Voice

Send a voice message on Telegram.

Your AI transcribes it and responds.

No typing needed.

Web

"What's the weather today?"

"Find me a pasta recipe."

"What's in the news?"

Anywhere

Message from your phone via Telegram.

Your AI is always available.

From anywhere in the world.

Set up in minutes, not hours

No coding. No configuration files. No "just SSH into your server."

1

Pick any device

A $5 Pi Zero, a $35 Raspberry Pi, that old laptop, your Mac or PC — whatever you've got. Your AI runs on hardware you already own.

2

Run one command

curl -fsSL https://crayfish-ai.com/install.sh | bash

Copy, paste, done. The installer handles everything.

3

Follow the wizard

Open your browser, fill in a few fields — your name, connect your email. That's it. Ready to go.

Built for everyone

Not just developers. Real people with real lives.

Busy parents

Juggling work, kids, and appointments. Let your AI keep track so you don't have to.

Small business owners

Drowning in emails with no time to hire help. Your AI handles the inbox overload.

Students

AI tools shouldn't require subscriptions you can't afford. This one is free.

Faith & community

Daily devotionals, prayer times, Shabbat planning — your AI respects your rhythm.

If you've ever felt like these tools weren't made for "people like you" — that you'd need a tech background or deep pockets — we built this for you.

Your hardware. Your AI.

Run it on whatever you have. No cloud required.
