Pros
Pro Consolidates all your information
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.
Pro Powerful features for organising your notes
Evernote is designed to make it easy to keep your notes well organized, which aids in quickly finding/browsing old information. You can put notes into a single notebook and use search to access old notes, or if you're so inclined, organize notes extensively with hierarchical notebooks and tags.
Pro Can include images, and snippets from the web or a whole webpage via web clipper
With one click you can clip part or all of any webpage, including text, images, and links. Especially for those who use Google Chrome, this web clipper is a very rich add-on. The “simplified article” mode strips all graphical overhead from the page before adding the information to Evernote. It's also possible to add highlighting, tags, etc. before storing the note.
Pro Has OCR functionality to convert images to searchable text
A really cool and handy Evernote feature is the ability to automatically scan images for text.
Pro "Reminders" are a great way to combine your to-dos and notes
One of the note types is a "reminder," which can act as a to-do list. You can add all the usual formatting to reminders, including audio. Evernote will provide alerts when they are due and house them in a special location within the app.
Pro Easy to use
Evernote is easy to dive into because it doesn’t overwhelm you with advanced functionality from the start. As you get more accustomed to the app, you might want to delve deeper to see what benefits the more advanced features will offer.
Pro Native and offline-capable apps on pretty much every platform
Evernote has apps for Windows 7 and 8, Windows 10, Windows 11, Mac, Android, iOS (both iPhone and iPad), Blackberry, and Windows Phone. It also has a fully functional web app and chrome plug-in. No matter what device or platform you're on, you will pretty much always be able to access Evernote.
Pro Multipurpose
In addition to general note taking and to-do list management, Evernote lets you search through scanned documents, handwritten text, and images; collaborate with others through shared notebooks; record audio notes; and more.
Pro Trustworthy to store data in the long term
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.
Pro Powerful note formatting
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.
Pro Great selection for integrating with other apps
The Evernote app center page is nicely organized and has good quality integration of apps that can improve your productivity.
Pro Focused, uncluttered user interface
Evernote has a very clean and intuitive interface that's simple to understand at a glance.
Pro Evernote is synchronized
Pro Premium allows search in attached files and documents
With a premium account you are able to search through PDFs and Office Docs.
Pro Innovative hacks
To save emails, just forward them to your Evernote email address generated on account creation. It is of course one of many such hacks.
Pro Flexible image manipulation
Permits photos that are taken, to be processed when in automatic mode and saved as a photo, black and white document, colour document, post it note or business card. The automated mode is also good at cropping the document effectively.
Pro Best web clipper
Can clip to the web from desktop or mobile, using simplified format or original formatting. Very quick and flexible, and enables you to highlight, take notes, tag, etc.
Pro Can choose from a few themes
You can pick from a green theme, light, or dark theme. All are very clear and visually appealing.
Pro Effective with pictures or snapshot of boards
Take a picture of your white board/paper board and you have it instantly in evernote everywhere, ready for additional notes and classification
Scannable friend app is rather efficient to keep hand written note as well.
Pro Skitch integration
If you're on iOS and have Skitch installed, you can quickly annotate your notes using Skitch.
Pro Has conflict management and undo
Allows undo/redo when editing (i.e. all changes are finalized upon saving). If conflicts between synchronized versions arise, both copies are saved in Evernote.
Pro Drag & drop files in channels
You can upload a file to any channel over HTTPS simply by dragging and dropping.
Pro Fantastic search functionality
You can deep search messages, files and snippets. Given Slacks integration into many external services, Slack is good enough to act as the central search interface for your entire team.
Pro @mentions
You can ping people to get their attention even if they are not online by @mentioning them. Slack supports desktop notifications.
Pro Very polished user experience
The entire Slack interface is polished and intuitive to use. There are very few bugs or inconsistencies in the UI and it's very fast to use. There is nothing in particular that is new with Slacks implementation of team chat, but the execution of the groups (called channels), search, external service integration and notifications is close to perfect.
Pro Apps for iOS, Android, Windows Phone, Mac OS, Linux, and Windows
Slack has apps for iOS, Android, Windows Phone, Mac OS, Linux, and Windows to give you the full functionality of Slack with some extra features not found on the website on most major platforms.
Pro Supports multiple teams
You can be signed into multiple teams simultaneously and quickly switch between them.
Pro Freemium plan
Free forever, only restriction on searchable message archives, up to 10k of your team’s most recent messages and 10 apps or service integration. Great for trying out first.
Pro Robust integration with a huge number of tools
Slack integrates with tools like Trello, GitHub, Dropbox, Mailchimp, and dozens of others, so you can have a centralized event feed of your project right alongside your chat. This is tremendously useful for keeping context with your discussions.
Pro Emoji reactions to limit excessive posts and notifications
Pro Multiple channels for different groups
Pro Syntax coloring
Pasted code can be colored based on syntax.
Pro Edit messages easily
It allows you to change what you sent by hovering to the message and selecting "Edit message" under the ellipsis (...).
Pro GIFS
easily embed gifs with /giphy
slash command.
Pro IRC connectivity over SSL
Pro Flexible, granular notification settings
Notifications are handled separately for mobile and the web app. You can receive notifications for all messages, just direct messages, or based on filters, and you can have different settings for different channels: you don't have to get notified every time someone pushed to GitHub or every time someone posts to off-topic chat, unless you want to.
Pro Inline link previews (photos, mockups, etc.)
When a link is added, some content in the link is shown such as image - like how Facebook does it when you share a link.
Pro Slackbot extensible chat robot
The "Slackbot" can is an extensible robot that can be set you remind you about tasks, auto respond to certain phrases and a variety of other functionality.
Pro Dev team is invested, responsive, and friendly
Having submitted both feedback and support requests for bot development, I can personally attest that the team takes feedback seriously, and responds quickly to communication. This is vital for any closed-source or hosted project.
Pro Shows local time of each participant
You can click on the profile of a user to see their local time. An especially useful feature when members of your team are working in different timezones.
Pro Self chatting
Creative implementation which is very good for personal journaling or drafting/collecting ideas. Previously, to do this, users needed to create a private channel with themselves. Note that some other team-chat apps may disallow creating group/channel with no 2nd person(s).
Pro Can Create Diagrams with Creately
You can just create flowcharts, org chart, mind maps, UML charts, infographics and many more by typing /creately new <document name>
Pro It can surprise you
There's a checkbox in preferences under advanced options that may surprise you.
Cons
Con Free version limited to 2 devices
The free version has become very limited as a cloud based note taking app as there is now only sharing between two devices allowed.
Con Pay for offline use, search, and other functions
The free version of Evernote is highly limited. You have to pay if you want to access your notes without internet connection, search your notes or documents, or upload large amounts of data. The free version allows you to upload 60 MB of data per month, which is about 20 to 30 iPhone camera pictures.
At a certain point, they started charging you for "advanced" capability, which includes searching your own attachments.
Con Different features and functions per device
Desktop app has table creation. Android app lacks font color changes. Some functions can only be accessed on the desktop app. These include changing your default notebook.
Con Security issues
Evernote had their entire database hacked and compromised including customer user passwords. They responded by locking valid users out of accounts and forcing password changes but are still vague about their own security policies. They do not have a good track record for data security. They also do not offer local personal encryption of entire Notebooks as Microsoft OneNote does.
Con Buggy
A program with more features is always prone to more bugs. Evernote is definitely not the most stable note-taking program available.
Con No official Linux app
Evernote does not offer an official Linux app, although there are some third party alternatives available.
Con Constantly directs you to upgrading your account
The frequent reminders to upgrade your account can quickly become disruptive. You get notifications when using the app, and many of the features that show as available in the app are actually for paid accounts only (which, when you try to use them, will remind you to upgrade).
Con Syncing is slow
Con Prices have doubled since Bending Spoon purchase
I used to pay 7 €/month, now it's 13.
Con Very heavyweight for a to-do list
Evernote is a powerhouse program with many features. It uses a correspondingly large amount of memory to run.
Con Missing some basic functions
Con Not distributed
One cannot run Evernote on own servers. This brings with it the risks normally associated with handing over critical applications to a large corporation.
Con Bending Spoon have relocated to Europe and fired 129 people
Con Poor text formatting abilities
Text formatting in Evernote is buggy and unreliable. Bullets (outlining) are getting stuck or disappearing, tables are very static and prone to breaking and everything beyond the most basic formatting might cause an issue.
Con Basic and lacking handwriting function
Handwriting has basic functions, is attached as a picture
Con Bloated and complex
Evernote is too big, has too many features. Note taking apps need absolutely clean interface to allow unobtrusive note taking and not a struggle to search for which buttons to click. It focuses on the search feature so much that it doesn't encourage or make it immediately easy to organize your notes and thoughts. It's essentially a sophisticated notes dump with good search.
Con New web editor does not support Firefox
As of now, Firefox users must download a separate extension to change their user agent to trick the Evernote site into giving them the beta, or install Chrome.
Con No recurring and snooze reminders
Perhaps because it is not truly a to-do list app, there is currently no support for recurring events or snooze reminders. The company claims to be working on this functionality.
Con Lacks search and replace capability
Con Rather poor user interface
Slow, not user friendly experience, complex, and somehow limited.
Con Lacks right-to-left writing support
When you write in a right-to-left language (Arabic, for example), everything looks fine in the editor but the direction changes to the left again after saving the note.
Con Steep learning curve
Since Evernote has so many features built in, it's hard to know where to find everything until reasonable amount of time has been spent with it.
Con Easy to accidentally hit the wrong button on the mobile apps
The mobile apps have fairly small touch targets, making it easy to miss the button or accidentally press the wrong one.
Con No ability to re-order notes other than sorting
Evernote has no way to re-order notes, nor even to change their display order. Sorting is the only option, and the "official" workaround (for years now) is to prefix note titles with line numbers manually so notes will sort and display as desired.
Con "Native" desktop apps are web apps
While it's great that Slack provides installable apps for Windows, macOS, and Linux, they're just the Slack web app wrapped in Electron shell. This means they don't offer the same level of native UX that a truly native toolkit app would.
Con Expensive when you need to upgrade
At $6.67 per user / month (or $8 if billed monthly) , Slack is significantly more expensive than the competition if you need features such as unlimited integrations (more than 10) or unlimited message storage (more than 10,000). However, the free version of Slack includes unlimited users.
However if you need only unlimited messages you can use storage services like https://slarck.com to upload then browse and search your entire message history, while staying in Slack's free plan. So with a combo of Slack+Slarck this con is not that major.
Con No self-hosting available
If you are worried about third-parties getting access to your data you should consider self-hosting. With self-hosting you are in control over where your data is stored, who has access to it. You will also not be vulnerable to exploits of a third-party provider.
Con Hidden max limit of free users per channel
Slack says that their free accounts support an unlimited number of users, which is true. However they don't mention that there is an undisclosed maximum number of users per channel (8462). For a large open source community, this is something to keep in mind.
Con Proprietary (non-free/libre)
Con Linux client is very RAM intensive
Con Slow and lags sometimes
Con No E2E encryption
Data is sent of SSL only, not E2E encrypted.
Con API doesn't allow custom widgets in chat
Con API is overall very poor
Can't do much with integrations.
Con Awful performance and constant glitches, since it is Chromium-based
You will experience a lot of hangs and glitches and it eats immense (for as basic as UI is) amount of RAM.
