With many utility tools being constantly shut down by their creators, it's really important to consider the long-term risks of picking a home for all your notes. Evernote is a $1 billion company with a track record of exceptional security and goals of becoming a "100 year old" company.

Evernote is designed to store a lot of different types of information from a lot of different sources in one place. Using the Web Clipper, native integrations, or a service such as IFTTT (If This Then That) you can use Evernote to store all your ideas, notes (both handwritten and typed), tasks, reading lists, receipts, and more.

Evernote has an extensive range of formatting options and note types. You can create checklists, reminder alerts, audio notes, or add images and attachments. It also has an awesome speech-to-text feature if you prefer to dictate aloud.
