One Day Investor
A calm, visual way
to watch your wealth grow.
Track every pocket, asset, and trend in one place.
Free. No spreadsheets.
Features
Built for how real portfolios actually work.
Pockets
Group holdings however you actually think about them — by broker, by strategy, by goal. Nest pockets as deep as you need.
Assets
Track every crypto and investment holding across every pocket in one searchable table. Live prices included.
Snapshots
Capture your whole portfolio on a schedule you pick. Every snapshot is a dated record you can revisit and compare.
Analytics
Distribution donut, timeline chart, largest holdings — the whole picture, always one click away.
Connect your exchanges
Link read-only API keys from the exchanges you already use.
Balances sync automatically into your pockets. Keys are read-only — no trading, no withdrawals, ever.
- Binance
- Bybit
- Kraken
- Coinbase
- OKX
- KuCoin
- Bitfinex
- Crypto.com
- Revolut X
Don't see yours? You can still track holdings manually from any exchange, broker, or wallet.
For your AI
Plug your AI into your portfolio.
One Day Investor ships a public, self-describing spec at /agents.json. Generate a token from the dashboard, paste a prompt into any LLM, and it can read your pockets, add assets, and take snapshots — with your say-so.
You are my portfolio assistant for One Day Investor.
Fetch the public manifest:
GET https://odinvestor.net/agents.json
Authenticate each request with:
Authorization: Bearer
The spec lists every endpoint you're allowed to call. Never guess one that isn't in it. Before any write, confirm with me in plain language.
First task: get my assets and describe them. Works with the AI you already use
ChatGPT, Claude, Cursor — anything that speaks HTTP. No vendor lock-in, no proprietary SDK.
You hold the keys
Issue tokens that expire in 1 hour to 30 days. Revoke any of them the moment you stop trusting the agent.
Nothing off-spec
The public manifest lists every allowed endpoint. If it isn't in the spec, your agent literally can't call it.
The idea
New here? Read why I built this.
Two minutes. No sign-up. The philosophy behind One Day Investor.
How it works
Invest one day a month. Here's the whole rhythm.
"One day a month. That's all it takes to watch your capital grow."
Step 1
Create a pocket
Group by how you think: Revolut, Interactive Brokers, Cash, Home. One pocket per service or per thing.
Step 2
Add your assets
Stocks and crypto auto-price themselves. Real estate, cars, and cash you set by hand.
Step 3
Take your first snapshot
One click captures the whole picture — a monthly photograph of your net worth.
Step 4
Come back once a month
We'll email you. Five minutes in the app, then close the tab and live your life.
Step 5
See the curve, not the ticker
Your capital over years — not yesterday's 0.3% dip. The one chart that matters.
Step 6
Build the habit
Twelve snapshots a year. A decade of snapshots is a decade of your financial story.
