Jules — your AI marine officer
Jules is AnchorQueen's AI marine officer. Ask a question and a veteran
crew member answers — by text or by voice.
The chat
A simple two-column conversation. Your messages on one side, Jules's
replies streaming back on the other, with avatars and timestamps.
A row of officer pills at the top lets you pick which officer you are
talking to. Each has their own background and area of expertise — a
meteorologist, a navigator, a passage planner. Tap a different officer to
switch context for the next question.
Beside Jules's avatar in the header sits a short status line that
reflects her current mood — calm, working, or a weather alert such as a
storm warning. It shows on one line and may end in an ellipsis when long;
tap it to expand the full message, and tap again to collapse.
Chat history
Jules keeps every conversation as a separate thread — just like ChatGPT,
Gemini, or Claude. Tap the history button (the clock-with-arrow icon)
at the top-left of the chat to slide open the chat-history drawer. It is
separate from the app's Left Menu — opening the history drawer closes the
Left Menu, and vice versa, so the two never overlap.

When you reopen the Jules tab, you land back on your most recent
conversation. If you are signed in, your chat history syncs across your
devices automatically.
Technical & Streaming Architecture
Jules is powered by a sophisticated multi-agent orchestration framework (CrewAI) integrated natively into our high-performance client engines.
CrewAI Multi-Agent Hierarchy
When you ask Jules a question, an Inference Router automatically evaluates your query and assigns it to the most capable officer persona:
* Meteorologist: Specialist in micro-weather forecasting, tide metrics, and wave analytics.
* Navigator: Focuses on spatial calculations, zone detection, and coastal seamarks.
Passage Planner: Connects with the A-APF routing engine to optimize passages.
Server-Sent Events & Chip Streaming Protocol
Tokens are streamed to the iOS/Android client in real-time. Suggestion chips are injected dynamically at the end of the streaming session using a specialized separator protocol:
Stream: "I recommend dropping anchor on the east side of the bay where the holding is solid."
Marker: "---CHIPS---[{"text":"Show on map","action":"zoom_in"},{"text":"Check weather","action":"meteo"}]---ENDCHIPS---"
To prevent raw JSON markers from showing on screen, the client uses a high-performance two-layer SSEStreamClient parser:
---CHIPS--- marker. It stops drawing text immediately upon detection, buffering the remaining bytes splitting-chunk-safe via an internal _safeEmitLength state machine, and decodes the suggestion chips in the background to render them instantly above the input field.Inference Routing & Engine Fallbacks
The client-side InferenceRouter dynamically routes requests based on connection capabilities:
* On-Device Inference: Uses MLXEngineAdapter and AppleFoundationEngine (via Swift MLX on compatible Apple Silicon chips) to answer basic navigation and offline dictionary terms without a network connection.
* Cloud Fallback: Automatically switches to the CloudGeminiEngine when complex weather or regional queries are asked, presenting a temporary Engine fallback banner.
Guidance & Best Practices: How to Interact with Jules
Jules is designed to be an active co-captain rather than a passive chatbot. Follow these best practices to get the most out of your conversation.
1. Give Jules a Long-Term Memory
Before planning a voyage, make sure your profile is updated under the Captain tab (with your boat name, draft, beam, air draft, and cruising speed). Jules accesses these parameters in every conversation:
Draft Checks: Asking "Is it deep enough in Setur Kalamış Marina?"* automatically resolves Turkish chart contours and compares them with your boat's draft.
Bridge Clearances: Asking "Can I pass under the channel bridge?"* triggers an immediate verification against your air draft.
2. Using Hands-Free Voice Commands
When sailing or helm-bound, typing is impractical. Jules supports high-fidelity local voice-to-text:
* Recording: Hold down the Microphone icon in the input bar. A wave-pulse indicator appears, confirming active recording.
Speaking: Speak naturally (e.g., "What is the swell forecast for the anchorage tonight?"*).
* Sending: Release the microphone button. The audio is immediately transcribed and processed.
3. Interactive Suggestion Chips
At the end of a query, Jules often streams in action chips above the chat bar:
* Map Control: If Jules describes a point of interest (e.g. a marina or danger reef), tap the Show on map chip. The chat drawer will slide closed, and the map camera will automatically zoom and fly to that exact coordinate.
* Context Switch: Tapping chips like Check weather automatically opens the Meteo tab, preserving your current coordinate context.
4. Selecting Your Officer Persona
Tap the pills at the top of the chat to target your query:
* Navigator: Use when asking about seamarks, maritime zones, territorial limits, or coordinate lookups.
Passage Planner: Use to request A-APF routes between marinas.
* Meteorologist: Use for micro-climate analysis, wave period trends, and storm track forecasting.

What Jules can do for you
Jules doesn't just answer questions — she acts on the chart for you.
Talk to her in plain language; you never need to read out coordinates.
When you say "here" or "near me" she uses your live GPS position, and
if there's no fix she uses the centre of the chart you're looking at.
The sections below show what to ask. Everything here works in everyday
language — these are just examples.
Weather & forecasts
Jules pulls live marine weather and multi-day forecasts for your
position or anywhere you name.
> "What's the weather right now?"
> "Give me the 24-hour forecast here."
> "What's the 3-day outlook for Mykonos?"
"Show me the week ahead — is there a good window to cross?"
She reports wind and gusts, waves, pressure, and conditions, and for
multi-day questions summarises each day's peak wind, wave height, and
rain chance.
Routes & navigation
Jules plans depth-aware routes that keep you in safe water, saves
them with a "Jules" badge, and can extend them.
> "Plan a route from here to Mykonos."
> "Take me to Delos, then on to Mykonos."
> "Add a waypoint at the headland to that route."
"List my saved routes."
Routes she plans appear in your Saved Routes alongside your own, clearly
marked so you can review, follow, or delete them.
Anchoring
> "Is this a good place to anchor?"
> "What's the seabed like here?"
> "How deep is it where I'm pointing?"
"How crowded will this bay be in a few hours?"
Jules reads the seabed type and gives a holding score, checks charted
depth, and predicts anchorage crowding.
Places, harbours & ports of entry
> "What's this place called?"
> "Find marinas near me."
> "Where can I clear customs nearby?"
"Any lighthouses or buoys around here?"
She names the bay, island, or town you're looking at, lists nearby
harbours and marinas with their facilities, shelter and approach data,
finds customs and immigration offices (ports of entry), and locates
charted seamarks — buoys, beacons, and lighthouses.
When you ask Jules to find a named place ("Take me to Setur Kalamış
Marina"), she searches exactly the same sources your own chart search
does — online places, the worldwide marina database, charted features,
and your saved marks — so she finds marinas and landmarks a plain map
lookup would miss. Each place Jules looks up is added to your Recent
searches in the chart search panel, tagged with her ✦ badge so you can
tell her lookups apart from your own (and filter to just hers).
Where am I?
> "Whose waters am I in?"
"Am I inside territorial waters here?"
Jules tells you the maritime jurisdiction — the territorial sea, EEZ,
and sovereign state — at your position or any point on the chart.
Live traffic & your chart
> "Any boats anchored near me?"
> "What's the live traffic around me?"
> "Show me Mykonos harbour." (Jules moves the chart for you)
> "Zoom in."
"Look at my chart and tell me what you see."
Jules reads nearby vessels (AIS) and other anchored boats, can pan and
zoom the chart to show you a place, and can even look at the chart
you're viewing to answer questions about what's on screen.
Drop marks
> "Drop a mark here called 'Lunch stop'."
"Mark this as a good anchorage."
Marks Jules drops are saved on the chart with your notes, tagged so you
always know which were hers.
Talk or type
Type in the input bar, or hold the microphone and speak — release to
send. Jules replies in your language, and her replies stream in as she
writes them.
Jules remembers you
Jules carries context across sessions and devices. Tell her your boat's
name, draft, and home waters once and she'll remember — so "is it deep
enough for me here?" already knows your draft. She also adapts to you:
she replies in your language and matches the persona to your profile.
Free, PRO & MAX
Jules is included with your captain account and free to use every day.
Free captains get a generous daily allowance of Jules conversations.
Heavy planning days — plotting passages, comparing anchorages, running
through forecasts — can reach that limit, and Jules will let you know
when you do. As you near the limit a "running low" banner appears
above the input bar, showing how much of today's allowance you've used
(for example 8.2k / 5k used) with a small gauge. When the day's
allowance is spent, Jules dozes off — her
octopus avatar closes its eyes with drifting Zzz in the chat header and
on the tab bar — and wakes again at the next daily reset (or right away if
you upgrade).
AnchorQueen PRO and MAX raise the daily allowance substantially, so
you can plan, ask, and explore all day without interruption. Upgrade any
time from the Store; your higher allowance applies to Jules
immediately.
Suggestion chips
Above the input bar, chips like "Is this anchorage safe?" or *"What's the
weather?"* offer one-tap starting points that pick up your live position,
weather, and boat state.
Banners
Three banners appear when relevant:
