AI Stock Navigator helps you explore official disclosures and illustrative scenarios for Japanese and US companies. Features and coverage depend on the installed version. Version 1.1 adds Japanese/English switching and an expanded stock catalog.

In version 1.1 or later, open Info → Display language and choose English or 日本語. Your choice is saved on this device.
Stock searches and analysis
Search by company name, Japanese security code or US ticker. Catalog search is free. Search results do not guarantee that financial disclosures are available for analysis. The expanded catalog is a dated snapshot, not an exhaustive list of every security; ETFs and OTC securities are excluded. Canadian-listed stocks are not included. If source data is unavailable, the app cannot generate an analysis for that issuer.
Scenario graphs
Enter a reference price in JPY for Japanese stocks or USD for US stocks. Bear, base and bull lines are illustrative assumptions from that manual reference. The app does not supply current or historical stock-price data. Scenarios are not validated predictions, probabilities or target prices.
When analysis is unavailable
Check connectivity, the app version and the displayed error. Daily allowances, shared operating limits, missing disclosures, maintenance or a service interruption can prevent new generation. Saved responses are historical and are not automatically updated.
Free and Premium
Free includes ads and one new stock analysis per Japan calendar day. Premium removes ads, enables favorites and allows up to ten new stock analyses per Japan calendar day. The shared service-wide limit during the trial is ten new AI generations per day and 300 per month. Analysis text and a scenario each require a generation when no saved response is available; language variants may require separate generation. Premium does not bypass the shared limit. See the in-app disclosures before subscribing.
