Don't like to pay?? Try ShareX
Lightweight screenshot tool offering OCR, exports to Office apps and online storage, integration with external commands, supporting 32 languages and minimal space requirement.
The OCR functionality is very useful and the annotation and markup tools are plentiful and easy to use; very small learning curve for a powerful tool.
Doesn't come near the ease and functionalities of what Snagit has. On the plus side, it is free.
Greenshot does not even come near Snagit. Very low usability. NOT intuive and the tools are on such a low level-I can`t even describe.
Flameshot is a free, open-source screenshot tool that is cross-platform compatible, offering customization, editing features, CLI scripting, and direct Imgur uploads for seamless sharing. It provides an intuitive user experience through features like area selection, annotations, and saving options.
Snagit stores the screenshots in their "native" format in its own gallery: the image and the annotations/editions (texts, arrows…). It is very handy when your workflow is to edit the modifications after the fact (ex: correcting the text). Flameshot only allows you to annotate the screenshot just after you took it, once it is exported to a standard image (JPG, PNG…) you cannot edit it any more. Also, Snagit allows to record screencasts. Flameshot feels really light and is free software.
If you're looking to make "8x10 glossy photograph with the circles and arrows and a paragraph on the back of each", it can't be beat. Lightweight, does its job, gets out of the way quick.
Flameshot is not an option until the project owner corrects the kde-frameworks dependency. https://github.com/flameshot-org/flameshot/issues/3119
Shutter is a feature-rich screenshot program for Linux based operating systems. It is free, open-source, and licensed under GPL v3.
At least on Linux is, stable, on official repos of main distros and with a lot of useful features... and is indeed currently active!
With SnagIt you can remove sections from anywhere in the image, close the orphaned parts together to remake the whole, strip out, reduce top,sides,bottom to make a new size, all in the one session. With shutter all you have is crop!
SnagIt is the best. Unfortunately only works with windows and osx. Shutter has the x11 limitation which is unfortunate as I use Wayland. Also I have to use a screenshot tool with anotations and markup mulitple times a day. Shutter unfortunately doesn't come close. Devs please add wayland support and also checkup snaggit for implementation ideas.
The OSS Document Scanner is a free and Open Source app to transform your mobile device into a powerful document scanner.
MakeACopy is an open-source document scanner app for Android that allows you to digitize paper documents with OCR functionality. The app is designed to be privacy-friendly, working completely offline without any cloud connection or tracking.
Ksnip is a Qt based cross-platform screenshot tool that provides many annotation features for your screenshots.
It is not as powerful as snagit, but the most common features it has - for me a perfect fit.
Spectacle is a simple application for capturing desktop screenshots. It can capture images of the entire desktop, a single monitor, the currently active window, the window currently under the mouse, or a rectangular region of the screen.
