Your external
hippocampus.

Seahorse remembers the people, projects and promises that matter, so nothing important slips through the cracks.

Most AI waits to be asked. Seahorse comes to you first.

Your AI, not a rented one

An AI that lives on your machine.

Seahorse runs AI locally on your own computer: private, free, no cloud required. Cloud models like Claude or ChatGPT are optional boosters you can plug in for the harder tasks, never something you depend on.

On your machine

Seahorse's AI runs on your own computer. Your memory, your data, your conversations stay with you. No internet needed for the core experience.

Scales with the task

Instant for everyday recall and quick actions, deeper when you need real reasoning. One Seahorse, the same voice, just at the right depth for the job.

Cloud, only if you want it

Plug in Claude or ChatGPT for extra horsepower on the hard stuff. Optional, never required, and you pay the provider directly. Seahorse never charges you a penny.

Built by Henry Kelly

15+ years in AAA games development across studios like Ubisoft, Rebellion, Gunzilla and Offworld. Seahorse was built because ADHD and autism made modern work feel impossible. So I built the system I always needed.

Free forever. Donate to keep us building.

Seahorse is free for everyone, always. No subscription, no paid tier, no time bombs. If it helps you and you can afford to, a one-off donation goes straight back into building it: more dev time, the harder integrations, faster local AI. Donations are thank-yous, never unlocks. Nothing in the app is ever locked behind one.
