The Capital One skill allows you to check your credit card balance or make a payment when one is due. This is secure: The skill performs security checks and requires you sign in using your username and password. Then, when you open the skill, you must provide a four-digit code to confirm your identity. Just be wary of who is around when using the skill -- anyone who overhears you say your personal key can access your banking or credit card info just by asking Alexa.

For tracking your food, you can use the Track by Nutritionix skill, which lets you record your food intake using your voice, or ask for caloric values of foods. (Alexa does the latter by default.) Say things like, "Alexa, tell Food Tracker to log a cup of almond milk" or "Alexa, ask Food Tracker how many calories are in two eggs and three slices of bacon."
You'll notice in the lists below that many Alexa skills are called by using trigger words like open, start, play and ask. While select skills require you to use specific terms, others consider them to be interchangeable and will work with some or all of these phrases. Over time you'll begin launching your favorite skills by the words you feel most comfortable using. Initially, though, it can be fun to play around with each.

If you think you’d like a briefing in the future, but not now, just toggle it off. If you want to permanently disable a Flash Briefing skill, you’ll need to head over to the Skills section in the app and then tap Your Skills.  Find the skill you want to disable and then tap Disable Skill. You don’t delete the skill, which makes sense since nothing installs on your Alexa device.
Flash briefings are great for quickly informing your audience, but a fully interactive Alexa skill or Google Assistant action will allow even more freedom. With a well-designed skill, you can provide personalized service and content to your audience at any time — not just once a day or week. With a voice chatbot analytics tool like we provide as Botanalytics, you can also receive helpful usage data to get to know your audience even better. 

Some Alexa Skills connect to smart devices, bringing voice control to a smart home from smart lights to locks, smart thermostats to televisions and more. Alexa becomes a home's second in command: users tell Alexa to tell other devices what to do. There are Alexa Skills for almost any kind of smart home device. These Alexa Smart Home articles can get users started immediately, quick start guides for using Alexa: 8 Alexa skills for your professionally installed and monitored security systems, 5 Alexa skills for security you install yourself, but have professionally monitored, and Alexa Skills that help lock down the security of your smart home.
Like all AI devices that use National Language Processing or NLP, Alexa does not understand all voices easily. But she learns to understand her people over time. She does, however, require people to speak in simple terms, with appropriate pauses, and use specific word orders. There are many times when she will say "I'm sorry, I don't know the answer to that question." More than likely, she doesn't recognize a word order or misunderstood the question.
