What the chat can do

The chat assistant has a built-in tool surface — over 60 capabilities it can reach for, often combined in one turn. So a single message can trigger a search, a calculation, a capture, and a follow-up question.

You don’t need to know the tool names. Ask in natural language.

How it works

When you send a message, Claude reads it, decides which tools (if any) it needs, calls them, observes the results, and writes back. If a job needs more than one tool, the loop iterates — up to 30 turns or 100 tool calls per message before the assistant is forced to wrap up.

What it can reach for

Your Moonjar library

Search and read documents. Find captures by keyword, semantics, or structured fields. Read a specific document by id.
Search and read past conversations. Pull up an earlier chat by topic.
Memories. Save, find, update, and delete memories. (See What are memories?.)
Collections. Create them, add fields, add items, query items, link items between collections, rename, reorder, delete. Just ask: “make me a list of plants with watering schedules.”
Reminders. Add, complete, list, edit.
Capture URLs. “Save this article: …”

The web

Web search — quick lookups.
Deep research — slower, multi-source synthesis. Runs in the background; you get a notification when it’s done.
Image generation and image editing.
Image search — find pictures by description.
Knowledge graph — structured facts.
Translation — between languages.
Books — search by title, author, topic.
News — current events.
Shows and movies — search and trending lists.

Real-world data

Weather — current conditions and forecast for any location.
Nearby places — restaurants, shops, services around a point.
Routes — directions and ETA between two places.
Flight status, search, schedules, airport delays — for travel questions.
Geocoding and timezones — translate addresses to coordinates; resolve a timezone for a place.

Actions Moonjar can take

Create reminders, notifications, automations.
Generate insights — “what should I follow up on this week?”
Suggest actions — quick-tap suggestions in the chat reply.
Show calculations — render arithmetic and unit conversion as cards.
Create artifacts — long outputs the chat keeps so you can re-reference them. See Artifacts.
Device tools — wake your phone or watch when an automation needs the device’s location, health, or notifications.

Bring your own tools

You can add your own outbound MCP servers — third-party tool surfaces (calendar, email, anything that speaks MCP) that show up in chat alongside the built-ins.

Limits

The assistant has a per-turn budget of 100 tool calls and 30 iterations. After that it’s forced to summarise.
Image generation and deep research are the slowest tools — both can take 30+ seconds to return.
Some tools depend on optional configuration (weather needs a weather provider key, books needs a books provider). If a tool isn’t wired up on your account, the assistant says so and works around it.
