Capture it any way you like.
The sorting happens without you.
By voice or by keyboard, however it comes. Ten seconds later, the people, the dates and the things to do are in their place, and you filed nothing.

No folder to pick, no title, no tag. You say or type a sentence, and sinam works out on its own what it is about.

One short capture,
three weeks later.
A single sentence, dictated while walking, and what it becomes without you looking after it.
“Marion had a baby boy on March 12, his name is Elio”
You dictate it in the street, in two seconds. You file nothing.
A card for Marion now exists, with a fact, a named child, and a date that comes back every year.
“lunch with Marion on Friday, she's going back to work”
The same card fills up. No duplicate: sinam knows it is the same person.
The Digest tells you: Elio's birthday in five days. You never set a reminder.
you ask your AI: “what do I know about Marion?”
It answers from your memory, not its own.
Three ways to find things, without searching.
Nothing is ever deleted: what you never reopen fades, like these cards. Hover over them to light them up again.
Your AI reads
your second brain.
From the desktop app, connect sinam to your AI assistant: Claude, or any MCP-compatible assistant. It finds a person, a decision or a project in your memory, without you having to explain everything again.
- It searches your memory by meaning, not by keyword
- It opens your cards: people, places, projects
- It can capture for you, straight into your inbox
At home. Not in a cloud.
- No account to create, no ads, no tracking
- Your memory lives on your devices, and each one keeps a full copy
- They sync over your Wi-Fi, directly, with no server in between
- The engine is open source: everything it does can be checked
On your computer, or with your key.
The local model sorts your captures on your computer. Nothing leaves, and there is nothing to pay.
Your Anthropic key, on a phone alone: the text of a capture goes out just long enough to be sorted, and the result comes back to you. Nothing else leaves, and you pay Anthropic for what you use.
