A familiar waterfront. An unexpected stop. A question that changes the whole trip. Nautilus brings a guide’s curiosity to the places you explore.
Android beta 0.3.1 · Windows experimental beta 0.1.0
Your own Gemini connection powers optional AI features.
History. Nature. People. Places. You.
ONE PLACE.
MORE TO DISCOVER.
Choose an experience to see how Nautilus approaches it. These illustrated examples explain the product; they do not make a live AI request or track your location.
Choose a place, ask a question, and look at it through a historical or contemporary guide perspective.
“What shaped the waterfront we see today?”
In the Android beta: type or speak a question. Gemini answers need your configured key and Internet access. Search-grounded research is a separate opt-in.
The original concept artwork brings the experience together across screens. It illustrates the product direction. Android personal beta and Windows experimental beta downloads are available below.
Original supplied concept artwork. Some illustrated capabilities are planned rather than implemented.
Local discovery tools and an optional AI connection are in the current Android build. The full platform vision remains in development.
Download the standalone Android installer directly. No app-store account or earlier Nautilus installation is required.
A separate experimental Windows x64 beta is available below. No iOS or macOS installer is available; Chromebook compatibility has not been verified.
Clearer connection and quota status, manual retry, answer-specific source links, replay and Android voice controls.
Direct beta download. No payment is collected on this page.
The standalone Windows edition opens in its own application window. Plan a tour, explore saved places and keep memories on your computer. Connect your own Gemini account when you want live answers.
Chromebook: some models support Android apps, but this APK is not a verified Chromebook release. The Windows application is a separate download.
Personal-guide desktop beta with tour editing, saved memories, voice controls and an optional Gemini connection. Windows device acceptance remains pending.
Download Windows EXE ↓Download ZIP with setup guide ↗Unsigned experimental build. Windows may warn or block the file. Requires WebView2; get the runtime from Microsoft if needed.
Windows x64 compilation, executable structure, embedded files, interface review and automated connection/error tests. Launching on Windows, live Gemini, file exports, camera, microphone, speech and location still need real-device verification. Laptop location may be too imprecise for arrival triggers.
Local samples, tours and memories work without Gemini. The key stays in memory for the current session. Live AI needs Internet and your own Google access. There is no automatic Android sync.

Allow installation from the browser or file app only when Android asks. Prefer an update to preserve local data. If installation fails, keep your working app and report the exact message.
Explore local samples first, or connect your own Gemini key in Profile. Test basic chat separately from optional Search. Google access, quotas and charges depend on your account.
Confirm real stop coordinates, allow location, and keep the app in the foreground. Try a short walking route before relying on trip playback. This is an interpretive guide, not navigation equipment.
Two ways to support Nautilus through the owner’s Venmo business account. Payment links and the scannable QR will appear when the business profile and app price are configured.
Payments are not active. No payment unlock or automatic verification is connected.
App pricing and purchase terms will be shown here before payments open. The current direct download is a personal beta.
Yes. Download the experimental Windows x64 EXE above. It opens its own desktop window using Microsoft WebView2. Windows device verification is pending; this is an unsigned beta. It does not require an Android emulator.
Some Chromebooks support Android apps, but device support and APK installation vary. Nautilus is not yet verified on a Chromebook and is not listed here as a separate Chromebook release.
Saved/local material and saved narration can be used without Gemini. AI questions and live research need connectivity. Nautilus does not provide full offline maps or a complete offline AI service.
The current Android beta uses a static illustrated guide. Speech recognition, AI text generation and Android text-to-speech are separate stages. Continuous Gemini Live audio/video and an animated avatar are not implemented.
Saved text, tours, stop pins and resized photos are stored locally. The app’s connection key is stored using Android’s encrypted key storage. AI requests go to Google; Search and location context require their respective settings and permissions. There is no cloud sync. Text export excludes photos and exact stop coordinates and is not a full backup. Uninstalling removes local app data.
Road-trip interaction is for passengers. Nautilus does not replace navigation, a lookout, required crew, or emergency judgment. GPS narration in this beta runs only in the foreground; locking the phone or leaving the app pauses the trip.
No. Nautilus does not include a shared AI subscription or unlimited requests. You configure your own Gemini account. Available models, quotas, Search access and any charges are determined by Google and your account settings.
The release adds clearer status labels, manual retry with cooldown protection, answer-specific source information, replay without another AI request, and Android voice choices. The package identifies itself as version 0.3.1, version code 7. Its supplied notes state that its certificate matches 0.3.0; phone updating still needs confirmation.
