Bring your own AI key

You choose the AI. We show the sources.

In most apps, the AI is the one they picked, written their way. Here you decide which provider and which model.

How data travels when you make an AI request

From Your phone Your key stays in the iOS keychain

Sent directly

To The AI provider you chose Gemini, OpenAI, OpenRouter, Anthropic

Our serversNone

  1. Choose who reads

    Gemini, OpenAI, OpenRouter or Anthropic: pick a provider and model, and switch any time. You can also sign in with an OpenRouter account and try a free model first.

  2. See the basis

    Every point has a source chip that takes you back to the paragraph it came from.

  3. See the usage

    You can see how many tokens each request used; models in the built-in list that have a listed price also get a cost estimate, while models with an uncertain price (for example, Gemini’s default model) do not. Costs are billed to your own provider account.

  4. Know where data goes

    Content goes straight from your phone to the provider you chose. Before the first use of each provider, the app tells you what will be sent and to whom.

The instructions given to the AI are fixed by the app: state facts and cite sources. If an answer reads like investment advice, the app asks for a rewrite once; if it still does, the whole answer is hidden. A point whose numbers do not match the original is hidden as well.

Works without a key: Today, Watchlist, Theses, Scorecard and the structured filing reader need no AI.

Free models vary in quality and have daily limits, and the upstream providers offering them may keep or train on what you send. On the Gemini free tier, Google uses content to improve its products. If that matters to you, use a paid model.

Up front

What it can’t do, stated first.

Having no servers of our own keeps your data on your phone. These limits are the cost.

  • Filings are one day delayed

    Filings come from the exchanges' end-of-day OpenAPI snapshot, which holds the previous day's announcements.

  • No real-time quotes

    Prices are end-of-day closes.

  • History starts on install day

    Monthly revenue trends and period-over-period comparisons build up on your phone from the day you install.

  • Alerts are not guaranteed

    There is no push server. New-filing alerts rely on the system occasionally waking the app, so they may be late or missed.

  • AI can be wrong

    Tap a source to check figures and claims; the original prevails.

  • No investment advice

    No buy or sell suggestions, ratings, price levels or timing, and no stock picks.

Privacy

No account. No tracking. No servers of ours.

Your watchlist, theses and trades live only on your phone, or in your own iCloud if you turn on Pro sync, which we cannot see. Your AI key stays in the iOS keychain. It is never synced or written to any log.
