Answers you can trust
It shows its sources, and admits when it doesn't know.
Checks before it claims
Factual questions search the web first, so sparky doesn't answer from memory when it could look it up.
An honest "I don't know"
When sparky can't tell, it says so instead of guessing. The same goes for a blank capture or a video it can't read.
Bring your stuff
Ask about the things you already have.
Save notes and documents for sparky to search, attach files to a chat, or link the apps you use and ask about them in plain words.

Questions
Good to know.
Is it free?
Yes, free to use with a fair daily limit. sparky routes your questions across free cloud models, and you can add your own provider keys to run chats on your own account.
Which phones does it run on?
Android phones. sparky is an Android app, and there is no iPhone version. The power-button assistant and circle to search use Android's assistant setting, which sparky walks you through on first launch.
How do I install and update it?
Tap Download for Android on this page. Your phone may ask you to allow installs from your browser the first time. After that, new versions download inside sparky and install in a tap.
Where is my data?
Chats and files live in your sparky account on our server, in private storage, encrypted at rest with a key of its own for each user. Only your account can see them. To write answers, your messages are sent to third-party model providers. You can delete any chat or file, or your whole account, in the app.
Does it need my location?
No. For weather and local answers sparky works out a rough location (city, state, country) only when you ask something local, without the Android location permission or GPS. You can switch it off in Settings, Privacy, or set your own city.
Can I use my own API keys?
Yes. Add a key from Groq, OpenRouter, NVIDIA or Ollama and your chats run on it. You can test a key in one tap and see requests, tokens and models used. Only you can see that usage.
