10 AI Glasses Scenarios I Tested With Just a Terminal

WAIC 2026 wrapped up in Shanghai last week. Every booth had hardware — AI glasses, brain-wave sleep devices, conversational labs. Specs everywhere: weight, brightness, battery.

But nobody answered the question I actually came with: what can these glasses do for me, today?

I went looking and found something interesting. The application layer that "agent glasses" promise — it's already buildable. Not next year, not after a firmware update. Right now, with a CLI tool and a phone camera standing in for the hardware.

The setup

# Install the Bailian CLI (requires Node.js >= 18)
npm install -g bailian-cli

# Authenticate
bl auth login
Enter fullscreen mode Exit fullscreen mode

Grab a free API key from the Model Studio console — the free tier covers everything below. Setup takes about five minutes.

Two commands do all the heavy lifting:

Command What it does When to use
bl vision Upload an image + a question, get a visual analysis Food, contracts, plants, gym equipment
bl chat Send text (optionally with a file or persona), get a response Planning, analysis, recommendations, chat

Health: Eat, train, track

1. Food calorie recognition

Point your camera at a plate:

bl vision --image lunch.jpg --prompt "Identify the food, estimate calories and key macronutrients (protein, carbs, fat)"
Enter fullscreen mode Exit fullscreen mode

I shot a plate of shredded pork with fish sauce over rice. Got ~650 kcal, protein/carb/fat ratios. Not lab-precise — but good enough to log a meal without manually searching a food database.

2. AI fitness coach

bl vision --image treadmill.jpg --prompt "Identify this equipment and generate a fat-loss plan: 3 sessions/week, 500 kcal per session"
Enter fullscreen mode Exit fullscreen mode

Recognized the treadmill, produced a structured weekly plan — exercise type, duration, intensity, target heart-rate zone. Beats wandering between machines at the gym.

3. Body metrics analysis

bl chat --file health-7days.json --prompt "Analyze 7-day health data trends (heart rate, steps, sleep, blood oxygen, stress). Flag anomalies and suggest improvements."
Enter fullscreen mode Exit fullscreen mode

Uploaded a week of smartwatch data. It caught a deep-sleep dip on days 3 and 5, correlated it with elevated stress scores, suggested an earlier wind-down. Whether that's medically actionable is a different question — but as a pattern-spotting tool, genuinely useful.

4. Smart diet manager

bl vision --image dinner-plate.jpg --prompt "Identify each dish, calculate total calories and macro ratios"
bl chat --message "Based on a fat-loss goal, suggest dietary adjustments for this meal"
Enter fullscreen mode Exit fullscreen mode

Vision identifies the food, chat adjusts the plan. Turns "I should eat better" into a concrete, per-meal instruction.

Family: The third eye at home

5. Parenting assistant

bl vision --image baby-blocks.jpg --prompt "Describe the child's activity and assess developmental stage"
bl chat --message "Log today's feeding, nap, and play observations. Generate a weekly growth summary."
Enter fullscreen mode Exit fullscreen mode

Photographed my one-year-old stacking blocks. The model identified it as fine motor skill development and logged the milestone. Not a pediatrician — but as a memory aid for sleep-deprived parents, it beats scribbling in a notebook.

6. Gift selection assistant

bl vision --image kids-room.jpg --prompt "Analyze this scene for gift-giving clues: interests, ages, existing items"
bl chat --message "Based on the scene analysis, recommend 3 gift options with reasoning and price range"
Enter fullscreen mode Exit fullscreen mode

Shot my kid's room. It spotted a half-finished Lego castle and a nearly empty skincare bottle. Inferred: a Lego expansion set for the kid, skincare restock for my wife, a family board game as a wildcard. More thoughtful than my default ("just get a gift card").

Business: Scan, assess, decide

7. Contract risk scanner

bl vision --image lease-contract.jpg --prompt "OCR this contract page and extract the full text"
bl chat --message "Review this contract clause by clause. Flag any risky terms (excessive penalties, unusual terms, hidden fees). Assign risk levels and suggest mitigations."
Enter fullscreen mode Exit fullscreen mode

Scanned a residential lease. It flagged a termination penalty clause as "high risk" (two months' rent — above local norms). My lawyer later confirmed it was worth negotiating.

8. Hotel search & booking

bl chat --message "Trip: May 20-22, 2 nights, near Shanghai Bund, budget hotel, total budget 1000 RMB. Find and recommend suitable hotels."
Enter fullscreen mode Exit fullscreen mode

Three options with price, location, rating, amenities — plus a comparison table and a booking recommendation. No camera needed. What I'd normally spend 20 minutes on across three booking sites.

Companion: From tool to partner

9. Visual Q&A

bl vision --image plant.jpg --prompt "What plant is this? What's its name (scientific and common)? How do I care for it?"
Enter fullscreen mode Exit fullscreen mode

Held up a succulent I'd been slowly killing for months. It identified it as an Echeveria, told me I was overwatering, and gave a care card: bright indirect light, water when soil is fully dry, every 2-3 weeks. The plant is now thriving.

10. Companion robot

bl chat --persona "You are XiaoZhi, a warm and cheerful companion robot. You pick up on emotional cues and proactively suggest activities or games." --message "I'm so happy today! Let's hang out!"
Enter fullscreen mode Exit fullscreen mode

A chatbot with a persona. Not groundbreaking on its own — but in the context of agent glasses with a visual feed and calendar, the potential is a persistent, context-aware companion that knows what you're looking at and what you're doing.

What actually changed

Task Before After
Log a meal's calories Search food database, estimate portions Snap a photo, get instant estimate
Start a gym routine Google, cobble together a plan Photograph equipment, state goal, get a structured plan
Review a contract Read every line, miss the buried clause Scan the page, get flagged risks with levels
Pick a gift Wander a store, guess Photograph the room, get targeted recommendations
Identify a plant Reverse image search, then find a care guide One command: name + care instructions
Book a hotel within budget Open 3 tabs, filter, compare State constraints, get a comparison table

The pattern: input gets simpler (a photo or a sentence), output gets more structured (tables, plans, ranked recommendations). The AI doesn't make the decision for you — it does the tedious processing so you can decide faster.

Who is this for?

  • Early adopters who bought AI glasses and are underwhelmed. The hardware is here; the application layer is what's missing.
  • Developers building for the agent glasses ecosystem. Qwen opened the door to third-party Skills. The CLI is the fastest way to prototype what a Skill could do.
  • Anyone who doesn't have glasses yet but wants a preview. Every scenario runs with a phone camera and a terminal.
  • Anyone whose daily routine includes repetitive information tasks. If you do it manually every week, there's probably a bl command for it.

WAIC 2026 made one thing clear: the AI hardware race is on. But hardware without applications is just expensive plastic. The real question isn't "which glasses are lightest" — it's "what can the glasses do for me that my phone can't?"

These 10 use cases don't answer that fully. But they show the application layer is already buildable today. The glasses just make the input frictionless — the intelligence is already there, waiting to be invoked.


What use case would you build first? Have you tried any CLI-based AI tools in your daily routine? Drop a comment — I'm curious what people come up with.
