Elevating Developer Experiences Through AI-Driven Documentation

Why Developer Experience Drives Business Strategy

At Newline™ by Fifth Third, developer experience isn’t an add-on, it’s the foundation of innovation. Every great product starts with a developer who can move fast, experiment freely and trust their tools. That trust begins with clarity, and clarity begins with strong developer documentation.

Done right, great documentation accelerates onboarding, reduces friction and builds confidence. That’s why we treat it as a core product, not an afterthought. For many clients, documentation is the first impression of Newline, and that’s why we ensure it reflects our commitment to clarity, transparency and precision.

What Developers Expect

We’ve studied what developers need when they open documentation:

• Clarity- Up-to-date content that gets to the point
• Ease of navigation- A structure that makes sense for engineers, product managers and business teams
• Real examples- Code-first samples that actually run
• Consistency- A unified tone and format across every page

How We’re Raising the Bar

We treat documentation like a product – with ownership, feedback loops and a roadmap. This means we offer:

• Docs as a product- Not an afterthought, but a core feature with ongoing enhancements and releases
• Built-in feedback- We listen and iterate based on developer input
• Always fresh content- Automated updates keep docs aligned with every release
• Developer-first tools- Fast search, copy-ready examples and interactive components
• Fintech standard: Clean, intuitive, and built for scale – more fintech, less legacy banking

Bringing AI Into the Experience

Documentation shouldn’t be static. That’s why we’re weaving AI into the heart of our developer experience with several new enhancements:

Conversational Search – Ask naturally, get answers instantly

Ask questions in plain English, like "What is a VRN?", and get:

• Clear answers
• Code snippets to copy
• Links to the right docs

SmartDocs – Always up-to-date, always in sync

Our docs now stay in sync with product updates and are structured for AI tools via LLM.xt. It means we can offer:

• Always-current content
• Consistent answers across search and assistants
• Less manual hunting for the latest information

Ask AI – Your favorite assistant, now inside the docs

Prefer using your own assistant? Use the Ask AI dropdown to send context-aware questions to tools like Microsoft Copilot^® or ChatGPT—without leaving the docs.

At Newline, we build like a fintech, not a traditional bank. We believe great developer experiences start with great documentation and we’re just getting started. Fueled by the power of AI, we’re building tools that help developers move faster and build smarter. Let’s build what’s next, together.
