While the market has a plethora of software documentation tools, how do you find your way out and pick the one tool that you really need? 

After rigorous research, we have compiled a list of the 15 best software documentation tools. We combed through dozens of websites to get you the top tools and make the process of decision-making a tad bit easier!

Let’s go!

What is Software Documentation? 

Software documentation is an online information resource that provides complete information about your software – its features, functionality, operations, and use cases. It is a highly searchable and meticulously structured document that helps users find all the information they need in just a few clicks. 

The documentation comprises step-by-step instructions demonstrated using written text, flowcharts, diagrams, and videos. It also provides troubleshooting tips to help users solve problems on their own and put your software product to maximum use. 

Remarkable Benefits of Software Documentation

Creating software documentation is a powerful strategy that SaaS businesses should adopt to keep their customers happy and internal teams super-efficient. There are scores of benefits that employing software documentation can shower upon your business. 

Let’s look at the most remarkable ones:

Reduces Support Tickets

Software documentation designed for customers can bring down your support tickets to a large extent. As a highly searchable document, it gives customers instant access to all the help they need every time they are stuck with your software and looking for solutions. 

The sheer convenience of solving problems on their own right when they arise prevents customers from raising tickets for minor issues. This reduces the inflow of tickets reaching your internal support team. 

Facilitates Onboarding of New Developers 

Onboarding new developers and familiarizing them with your software development process is a cumbersome task that requires considerable time and resources. With an internal software document, you can onboard new developers to the team by providing them easy access to all the training material and technical information they need. 

Software documentation guides new developers on all important aspects of your software – how it was developed, the stages it went through, and even the stakeholders involved in the process. This helps them gain a grip on your existing processes quickly. 

Minimize Errors 

When humans are involved in a process, errors are bound to occur. The good news is that software documentation can help you minimize the occurrence of errors, ensuring that the final output is flawless. 

When every team member has access to the same information, they will be following the exact same steps given in the documentation. This not only brings consistency to how a software development process is performed but also increases accountability in teams. 

Deliver In-App Help to Customers 

With software documentation, you can deliver instant in-app help to customers right inside the software. Modern tools for software documentation offer an in-app help widget where you can display help articles and walk customers through how your software works. 

While working with your software, customers can instantly search for suggestions and refer to the instructions. This keeps them on the right path and helps them accomplish their goals faster.

How to Choose the Right Software Documentation Tool 

Choosing the right software documentation tool is an ordeal if you don’t know what to look for. However, when you have clarity on the features you should consider, you will be able to make a well-informed decision. 

Here are some of the top features that your software documentation tool must have: 

• Online editor – An easy-to-use editor helps you write, edit, and publish your software documentation quickly. 
• Ready-to-use templates – Templates are designed to do all the heavy lifting in terms of the document’s structure and design. This means you can fully focus on the writing part. 
• Customization options – The software documentation tool you choose should offer extensive customization options to help you tailor the document to your company’s branding. 
• Contextual help – Your software documentation platform should be equipped with tooltips, lightboxes, and popups. These are essential tools to provide context-relevant guidance to users. 
• In-app help widget – This is a crucial feature that lets you provide instant, anytime, anywhere support right inside the software. 
• Built-in reports – Reports give detailed insights into how your articles are performing and what needs to be improved. Such data-driven insights can be leveraged to optimize your document’s performance. 
• Robust Integrations – Any documentation tool you choose should play nicely with external ticketing, chat, survey, analytics, and other such platforms. Integrations speak volumes about a tool’s capabilities and therefore, they are a must-have.
