Tell Phoebe your goals.
It runs your portfolio.
Phoebe researches every morning, buys when your prices arrive, puts a stop under every position, locks in profit at each target and sells when the plan says so — inside limits you set, even when your phone is put away.
You set the limits before anything is bought or sold. One switch stops it, any time.
First
You tell Phoebe your goals
In plain English: what you are investing for, what is worth owning, what to avoid, how bold to be. Phoebe reads it every morning and again whenever a price arrives.
Then
You set hard limits
How much it may spend in a day, the most any one position may take, and how often it may buy at all. These are enforced in code — not by judgment.
After that
It runs the portfolio
It researches, buys when your prices arrive, protects each position with a stop, takes profit at targets and sells. No notifications asking permission. No screen to sit in front of.
Selling
It never lets a green trade go red.
The moment Phoebe buys, the position gets a stop below it and three targets above. When price reaches the first target, the stop moves up to what you paid — from then on the worst the trade can do is break even. At the second target the stop rises again. At the third, it sells and the money goes back to work.
Stops only ever move up. Phoebe never lowers one, never sells more than you hold, and never shorts. If the stop is hit instead, it sells the position and writes down why.
- Bought at $398.12. Stop $384, targets $412 · $426 · $440.
- Target 1 reached. Stop moves up to $398.12 — what you paid. From here it cannot close at a loss.
- Target 2 reached. Stop moves up to $412. The gain is locked in.
- Target 3 reached. Sold at $440.06. The cash goes back to work.
Illustration. A stop triggers a market order; in a fast or gapping market the fill can differ from the stop price.
Your limits
Shown again whenever a limit changes. Nothing new is ever agreed to silently.
The limits
It cannot spend more than you said.
Every buy is checked against your limits before it reaches your broker. If any check fails, nothing is bought and the reason is written in your journal.
- Auto-investing still switched on
- Your plan and limits can be read
- No margin, no short selling
- A stock it is allowed to buy
- Market actually open
- Not a repeat of an order already placed
- Within your buy-frequency limit
- Inside your position size cap
- Enough cash available
- Within today's budget and your total cap
Phoebe also holds its own ceilings above yours: a daily budget of at most $10,000 and no more than four buys in a day, whatever you set.
If you change your mind
One switch stops it.
Turning auto-investing off halts every new buy immediately, and nothing you hold is ever liquidated because you flipped a switch. Positions already under a stop keep it. Your plan, limits and journal stay exactly as they were.
Your plan
Written in words, not settings.
Your goals and your strategy are a plain-English document you can read and edit, not a grid of toggles. Phoebe reads it when it weighs a morning's research, when a price arrives, and when a position reaches a target.
Change a limit and it shows you the summary again before anything takes effect.
Coming: talking it through with Phoebe in conversation, and asking it why it chose what it chose.
Your goals and strategy
What I am investing for
Steady growth over the next five years. I would rather miss a run than sit through a crash.
What makes an opportunity attractive
Price at or below a well-established support level, or entering a defined support zone. Multi-timeframe lows that agree with each other.
Conditions that cause a stock to be ignored
An earnings event or other major catalyst is imminent. Adverse company news since the original research.
When to sell
Lock in profit at each target. Once a position is ahead, never let it close below what I paid.
What you see
It tells you what it did, not what it might do.
Phoebe bought
Bought MSFT — filled 2 shares at $398.12. Stop $384, targets $412 · $426 · $440.
Stop raised
MSFT reached its first target. Stop moved up to $398.12, what you paid.
Phoebe sold
Sold MSFT — filled 2 shares at $440.06. Up $83.88 on the position.
Phoebe passed
NVDA reached its zone, but earnings are in 3 days. Nothing bought; the reason is in your journal.
Needs you
Your broker connection expired. Watches and stops stay in place, but nothing can be bought or sold until you reconnect.
Daily summary
Nothing reached your zones today.
Exact numbers, no emoji, nothing promotional. Each kind can be turned off.
Your money
It never leaves your brokerage.
Your account, your name
Phoebe connects to your Robinhood Agentic account, which you open and fund yourself at Robinhood. It never holds your money, and there is no Phoebe account to fund.
It cannot move money out
Phoebe can buy and sell. Transfers, withdrawals and deposits are not something it is able to do at all.
Never your password
You sign in on your broker's own page. Phoebe receives a token, encrypted and stored separately for each person.
Locked to your face
Face ID or your passcode every time the app opens, because it is connected to your brokerage.
Why hand it over
The plan is easy. Tuesday is hard.
Most people who lose money in the market are not bad at picking companies. They are bad at holding on to what they concluded once the screen turns red and their hands get involved.
A plan written on a calm Sunday is a careful thing. It names what is worth owning, what you will pay, and when you will take the profit. The same plan remembered mid-drawdown becomes flexible: the price you would not pay becomes the price you pay, and the gain you meant to take becomes the loss you sit through.
Phoebe's whole design is to keep Sunday's plan intact through Tuesday. It does not get impatient, does not chase a stock that already ran, does not hold a winner until it is a loser, and does not quietly revise your limits to fit what it just did.

The ones worth asking first.
Does it really buy and sell without asking me?
Yes. You agree once, at setup, to the limits you have written — and after that Phoebe buys inside them, puts a stop under every position, and sells at a target or at the stop without stopping to ask. That is the point of it, and the reason the limits matter as much as they do.
What does "never lets a green trade go red" mean?
Every position gets a stop below it and three targets above, set the moment it is bought. When price reaches the first target, the stop moves up to what you paid. From then on the position can close for a gain or for what you paid, but not below it — the stop only ever moves up, never down. In a fast or gapping market a stop fills at the next available price, which can be a little under it; that is market mechanics, and the disclaimer says so plainly.
What stops it from emptying my account?
A budget for each trading day, an optional cap on the total it may have in play, a cap on how much any one position may take, a limit on how often it may buy, and Phoebe's own ceilings above yours. Ten separate checks run before any buy reaches your broker, and a single failure stops it.
Can I stop it?
One switch in Settings halts every new buy immediately. It never liquidates what you hold, positions already under a stop keep it, and nothing about your plan or history changes.
Does it manage the whole portfolio?
Position by position, yes. It buys what fits your plan, protects each holding with a stop, locks in profit at targets, sells, and puts the proceeds back into the next opportunity inside your limits. It only ever sells what it bought for you; anything you hold outside of Phoebe is left alone.
Who holds my money?
Robinhood, in the Agentic account you opened yourself. Phoebe never takes custody of funds and has no ability to transfer or withdraw.
How does it decide what to buy, and when to sell?
Each morning it researches the companies in view and notes any price zone worth waiting for, writing down its reasoning in plain language. When a price reaches one of those zones it looks again with fresh information, then either buys or explains why it did not. Selling is not a judgment call: the stop and the targets are set the moment it buys, from how much that stock typically moves, and they fire on price alone. Every decision is in your journal, including the ones where it did nothing.
Is this financial advice?
No. Phoebe is software. It is not a registered investment adviser, broker-dealer, or financial planner, and nothing it produces is a recommendation. Investing carries a real risk of losing money.
What does it cost, and how do refunds work?
$4.99 a month or $53.99 a year once Phoebe is on the App Store, with no free trial. Apple handles all billing — you cancel in iPhone Settings, and refunds are requested from Apple directly at reportaproblem.apple.com. The TestFlight beta is free.
