Introduction
A Wiki is a collaborative knowledge-sharing platform that allows teams to create, organise, update, and access information collectively. Unlike static documents or scattered files, wikis centralise institutional knowledge in a structured, searchable, and continuously evolving format. They serve as a single source of truth for processes, policies, technical documentation, onboarding guides, FAQs, and institutional memory.
In today’s fast-moving, distributed work environments, wikis are essential. They reduce dependency on individuals, prevent knowledge loss, improve cross-team alignment, and significantly cut down time wasted searching for information. From startups documenting early processes to large enterprises managing complex operational knowledge, wikis enable scalable collaboration.
Common real-world use cases include:
- Employee onboarding and training manuals
- Product and engineering documentation
- Internal policies and SOPs
- Customer-facing help content
- Research, notes, and project knowledge hubs
When choosing a wiki tool, buyers should evaluate ease of editing, content structure, permissions, search quality, integrations, scalability, and security controls. The right wiki blends simplicity with governance, allowing content to grow without becoming chaotic.
Best for:
Wikis are ideal for product teams, engineering teams, HR, IT, support teams, educators, startups, SMBs, and enterprises that rely on shared knowledge and frequent documentation updates.
Not ideal for:
Teams needing only short-term notes, real-time chat, or file-only storage may find simpler note-taking tools or document repositories more suitable than a full wiki system.
