CAPABILITIES
Everything you need, in one place
Voice-powered, always-on AI that manages your day, answers everything, and works the way you do.
AI CHAT
Ask Callisto anything — from quick facts to complex questions. Just type in the chat box and press Enter or click the send button. Callisto remembers everything you've discussed across sessions, so it always has context on who you are and what you need.
WEB + APP
VOICE CONTROL
Go completely hands-free from anywhere on your computer. Press Ctrl + Shift + C in any app, tab, or window — Chrome, Word, YouTube, anywhere — and Callisto instantly starts listening, no matter what you're doing. Speak your command, and it responds. On web, use the mic icon in the chat bar. Say things like "What's the weather today?", "Play something upbeat", or "Remind me at 6pm" — Callisto hears you and responds with voice and text.
WEB + APP
PERSISTENT MEMORY
Callisto learns your name, preferences, daily habits, and relationships — and never forgets them. Just tell it once: "My name is Hammad" or "I prefer dark mode and jazz music." From then on, every conversation is personalised to you, automatically, across all devices.
WEB + APP
GOOGLE CALENDAR
Connect your Google account to sync your schedule. Ask things like "What do I have on Thursday?" or say "Add a dentist appointment at 3pm Friday." Callisto reads, creates, and edits events using natural conversation — no need to open Google Calendar at all.
WEB + APP
LIVE NEWS
Get up-to-the-minute headlines from BBC, Reuters, Sky News, and more. Say "What's happening in the news today?" or "Give me the latest sports headlines." Callisto pulls real-time feeds and summarises them clearly — no browsing required, no ads, just the news.
WEB + APP
WEATHER
Ask "What's the weather like today?" or "Will it rain in London this weekend?" Callisto uses your location automatically or lets you specify any city. You get current conditions, hourly forecasts, UV index, and feels-like temperature — all in a natural reply.
WEB + APP
IMAGE RECOGNITION
Callisto can see anything on your screen. Press Ctrl + Shift + X in the desktop app to trigger Magic Vision — Callisto captures what's on your screen and analyses it instantly. Ask "What does this graph mean?", "Read the text in this screenshot", or "Explain what's on my screen." On web, click the paperclip icon to upload any image — homework, receipts, charts, or photos — and ask anything about it.
WEB + APP
MUSIC CONTROL
Link your Spotify account and control your music entirely by voice or text. Say "Play something chill", "Skip this song", "Pause", or "Play Drake's latest album." Callisto handles playback, search, and queue management without ever touching the Spotify app.
WEB + APP
STOCKS & FINANCE
Ask "What's Apple's stock price?", "How is the TSX performing today?", or "Give me a summary of Tesla's financials." Callisto pulls live market data, company news, and price history — no account needed. Great for staying on top of your investments during the day.
WEB + APP
WIKIPEDIA CARDS
Ask about any person, place, animal, or historical event and Callisto shows a rich visual card — image, summary, and a Wikipedia link. Try "Tell me about the Roman Empire" or "Who is Nikola Tesla?" The card appears instantly on the side panel without interrupting your conversation.
WEB + APP
DOCUMENT CREATION
Generate professional documents in seconds. Say "Write me a cover letter for a marketing job" or "Create a business proposal for a coffee shop." On the desktop app, documents are saved directly to your computer as Word files. On web, they appear in the chat ready to copy or download. Pair it with Magic Edit (see below) to refine any text anywhere after it's written.
WEB + APP
MAGIC EDIT
Edit text in any app, website, or document without copy-pasting. Highlight any sentence or paragraph in Chrome, Word, Notepad, Google Docs — anywhere on your computer — then press Ctrl + Shift + E. Callisto reads what you've selected and asks what you'd like to do with it. Say "Make this more professional", "Shorten this to two sentences", or "Fix the grammar" — and it rewrites the text directly in place, right inside whatever app you're using.
APP ONLY
REMINDERS
Never forget anything. Say "Remind me to call mum at 7pm" or "Set a reminder for my meeting tomorrow at 10." Reminders appear in the calendar panel on the right side of the screen and trigger a notification at the right time. You can also view and delete them from the panel anytime.
WEB + APP
TASKS & MORNING BRIEFING
Tasks belong to a day rather than a clock time. Say "Add a task to finish my chemistry homework" or "Put the supplier invoices on my list for tomorrow." The next time you open Callisto that day it greets you, tells you the weather, reads your tasks back — "You have 2 tasks today: finish the chemistry homework and call the supplier" — then the day's headlines. Tick tasks off in the panel; anything you don't finish carries over.
WEB + APP
CAST TO TV
Send what you're watching to the television. Say "Play this on the TV" and Callisto finds your Chromecast on the network and casts to it — no phone, no remote, no hunting for the right input.
APP ONLY
CONTACTS & CALLS
Save people to Callisto's contact list by saying "Save John's number as 647-555-0192." Then call or message them anytime: "Call John on WhatsApp" or "Send a WhatsApp message to Sarah saying I'm on my way." Works through your default apps on the desktop version.
APP ONLY
HOMEWORK HELPER
Struggling with a problem? Just ask. "Explain photosynthesis step by step", "Solve 3x² + 5x − 2 = 0", or "Help me write an essay intro about the French Revolution." You can also snap a photo of your textbook and ask Callisto to explain exactly what's on the page.
WEB + APP
SECURE & PRIVATE
Sign in securely with Google or email. Everything is encrypted in transit, and tokens for accounts you connect stay on your own device. Callisto never posts anything for you without your confirmation, and we never sell your conversations or personal data. You can disconnect any account at any time and ask us to delete your data — see our Privacy Policy.
WEB + APP
HAND ENGAGEMENT
Control Callisto without touching your keyboard or mouse. Click Engage Hand Movement in the app to activate the camera. Your left hand controls the Callisto Cursor — index finger moves it across the screen, pinch (index + thumb together) to click. Your right hand activates voice listening — hold up a peace sign ✌️ to start speaking. A real-time neon skeleton overlay shows your hand being tracked.
APP ONLY
3D STUDIO
Describe anything and Callisto builds a real, fully coloured 3D model you can spin, tilt and zoom. Say "Make me a 3D model of an Iron Man Mark 42 suit." Click any part — like the helmet — to change its colour, size or shape, or just say "make it black and silver". Use your right hand to rotate and zoom and your left hand to select, then download the model as a .glb file. Close the studio while it builds and Callisto lets you know when it's ready.
APP ONLY
AI VIDEO
Turn a sentence or a photo into a short video. Attach a picture of your car and say "Make a video of this car racing a cheetah", or describe a scene from scratch. Your video plays in the Video Studio the moment it's ready — keep working while it renders, then download it or post it straight to your socials.
APP ONLY
POST TO YOUR SOCIALS
Connect your YouTube, Instagram and TikTok business accounts and publish by voice. Attach a video or photo and say "Upload this to my YouTube channel as unlisted" or "Post that on Instagram." Callisto shows you exactly what will be posted — title, caption and visibility — and nothing goes live until you press Publish.
APP ONLY
ARTIFACTS
Every image, 3D model and video you create this week, collected in one gallery in the sidebar. Filter by type, preview videos on hover, reopen models in the 3D Studio, and download or delete anything in a click. The gallery refreshes every Monday so it stays focused on what you're working on now.
APP ONLY
EXPERT ANSWERS
Ask about accounting, finance, tax, business, law, science — any subject — and get a clear, well-structured answer right in the chat: a direct answer first, then headings, steps, tables and worked examples. Try "How do I record depreciation?" or "Explain EBITDA vs net profit." Callisto only makes a document when you ask for one.
WEB + APP
VOICES & ACCENTS
Choose how Callisto sounds. Pick a male or female voice with a British, American or Australian accent in your account settings, and every spoken reply uses it — on your desktop and anywhere you use Callisto.
WEB + APP
SMART SHOPPING
Say "Find me wireless headphones on eBay" and see real products with photos, prices and links, right in Callisto. You can also jump straight to results on Amazon, AliExpress and Temu — no more switching between tabs to compare.
