In your hand

Tell Spike everything.

Spike remembers, like a good AI should. But every name, number, and identifier gets tokenized on-device the moment you speak it.“Anna” becomes Person_1 on-device before it touches Spike’s memory, and well before anything reaches the cloud.

Persistent memory. Spike recalls what you told it last week.
Entity stripping. Names, numbers, places swapped for tokens.
On-device first. Stripping happens before Spike sees a thing.
Proxy as backup. The cloud only ever sees the redacted version.
How it works

Three taps to a useful answer.

No onboarding wizard, no API key, no setup.Just the space between having a question and getting an answer.

Step 01
Spike, listening with cupped ear

Open & speak.

Tap the mic. Spike waits, listening. No typing. Talk like you would to anyone in the room.

no typing · just talk
Step 02
Spike, holding a small wooden shield forward, protecting your private data

Spike protects you.

Names, numbers, addresses become tokens on-device. Only the redacted version ever leaves your phone.

on-device first · proxy second
Step 03
Spike, celebrating, arms up

Spike remembers. You stay you.

Tomorrow you pick up where you left off. The real names live on your phone, and nowhere else.

memory ≠ surveillance
Always private

We can’t sell what we never see.

Free tier runs locally. Nothing leaves the phone.Premium routes longer questions through a proxy, but names and numbers are stripped on-device first. The cloud answers a question. It never learns who asked.

A hand-drawn pipeline on torn cream paper. A speech bubble labeled YOUR WORDS reads ‘Email Anna about the $4k invoice’ and points to an iPhone marked ON-DEVICE, where a pair of scissors snips the prompt, with a label reading ‘names + numbers stripped’, beside a small padlock. Stripped tokens Person_1 and $Amount_1 travel out to a watercolor cloud labeled CLOUD · answers only · no identities, which returns an ‘answer’ arrow back to the phone.
Free, on-device. $0 / forever

Nothing leaves the phone.

Not your questions, not Spike’s answers, not what Spike remembers about you.

Apple Foundation Models · ~3B params · Neural Engine

No network use for inference. Audit it on a flight.
Premium, stripped & proxied. $7.99 / month

Names stripped before the network sees a byte.

Spike’s proxy forwards your tokenized question, returns the answer, and keeps no log of either.

For longer questions · larger context

Stateless cloud. We can’t see who asked. Only the redacted version of what was asked.

Meet Spike

A small desert cactus with a surprisingly good answer.

Spike is the friendly part of an AI you can actually trust.Ask about your spreadsheet. Ask about a weird rash. Ask why you keep snoozing your 5:40 alarm.

Spike doesn’t grade you, judge you, or tell anyone about you. The conversation stays on your phone. Spike’s memory of you, too.

“I’m not a doctor, a coach, or a journal app pretending to care. I’m closer to a porch light.” Spike’s promise
Notes from early conversations

What friends say.

New spots open every day. These notes are from the first batch, friends who’d been asking each other this stuff anyway.

Notes from the alpha

What testers built with Spike.

Real quotes from real testers. Names withheld because trust is the whole point.

“Spike helped me write back to a friend I’d ghosted for two months. Took four drafts to land it. Only Spike read the rough ones.”
Early friend
“Spike asks about my morning runs. I told him I was trying once. No app, no leaderboard. Just a friend who remembered.”
Early friend
“Spike knows I get cranky before lunch. When I tried to send a snippy email yesterday, he asked me to wait. Nobody else would have caught it.”
Early friend
“Real alpha quote #1 goes here. Keep the setup → middle → italic privacy-punchline shape.”
Alpha tester
“Real alpha quote #2 goes here. Different value beat than #1 and #3.”
Alpha tester
“Real alpha quote #3 goes here. Italic punchline carries the privacy beat.”

Spike, idle, waiting for you.
