GrantAi Personal · Your personal memory companion
The AI that's yours.
It remembers you. Word for word, on your phone.
Speak it, type it, or share it in. Ask for it later, in your own words. Get the original back, with its date.
No account to create • Private on your device
One save. One recall.
Say it once. Ask for it however you like.
You get the original back, not a paraphrase, with the date it was said.
“Dad wants the Ken Burns Vietnam box set. Don’t tell him, I want to surprise him.”
“What was the gift idea for my father?”
You said: “Dad wants the Ken Burns Vietnam box set. Don’t tell him, I want to surprise him.”
Recalled from 18 days ago
Speak it, type it, snap it, or share it in from another app. The recall works the same way for all of them.

Illustrative scenes. The screen shown is the real app.
Privacy, precisely
What stays on your phone, and what does not.
Stored on your phone
Every memory lives in an encrypted database inside the app on your phone. We keep no copy of your memories and there is no account holding one. Backups go to your own iCloud or Google account.
Sent for an answer
When you ask a question, the app sends that question, the memories it matched and the recent messages of that conversation through our relay to Google Gemini, over an encrypted connection, so it can compose the reply. If you have turned on location, or add a document or photo, those go with it. For current events, part of a question may be used as a Google Search query. Nothing is stored along the way.
Zero retention, in plain words
Google processes that request under no-retention terms: it is not stored after the answer is written, and it is not used to train models. Our relay forwards it and keeps only usage counts. Your memory database stays where it is.
Security details
The on-phone database is SQLCipher, AES-256 encrypted, keyed on the device. Requests to the AI model travel over TLS. Every memory is sealed with a SHA-256 hash and a timestamp when it is saved, which is how a recall can show exactly when something was said.
How it compares
Memory you keep, not memory you are lent.
Both ChatGPT and Claude now remember. The difference is what is kept, and where.
| Feature | GrantAi | ChatGPT Plus | Claude Pro |
|---|---|---|---|
| What is kept | Your exact words | A saved-memory list plus a synthesized summary of past chats | A synthesized summary of past chats, by topic |
| Where it is stored | Encrypted on your phone | OpenAI's servers | Anthropic's servers |
| Shows when it was said | Every recall carries its date | Not shown in recall | Not shown in recall |
| Searching your memories offline | Yes | No | No |
| Stores your memories in the cloud | Never | By design | By design |
Competitor rows describe each product’s own published documentation as of September 18, 2026: OpenAI, Memory FAQ and Anthropic, How does Claude’s memory work. Both keep a model-written summary on their servers; neither documents a per-recall date, and neither searches memory without a connection. We will update this table when their documentation changes.

FAQ
Common questions
What does it cost?
GrantAi Personal is a subscription, billed through the App Store or Google Play. Plans and prices are on the pricing page. See pricing →
What happens if I lose or replace my phone?
Your memories are part of your phone's normal backup: iCloud backup on iPhone, Google backup on Android. Set up a new phone from that backup and they come with it. GrantAi keeps no copy of your memories, so a phone that was never backed up cannot be recovered by us.
Can I export my memories?
Not yet as a file. You can search and read every memory in the app and share any answer out. Memories are never locked inside a cloud account, because there is no cloud account.
Do my memories work offline?
Searching and reading your memories works offline; they are on the phone. Asking GrantAi to write an answer needs a connection, because the answer is composed by the AI model.
Does anyone train on my conversations?
No. We never store your memories. The question and the few memories it matches pass through our relay to Google Gemini to compose the answer, under no-retention terms: the request is not stored and not used for training. The Privacy Policy lists exactly what is sent.
Does it work on Mac and Windows?
GrantAi Personal is on iPhone and Android today. Mac and Windows are coming. Each device keeps its own memories; there is no sync between devices yet.
What about enterprise or team use?
GrantAi Personal is for individuals. For teams, on-premise deployment and compliance features, see the enterprise offering. Enterprise →
Is there a free version for developers?
Yes. The developer edition is a memory server for Claude Code, Cursor and any MCP client. No account, no key, one command. Developers →
