## Overlayer (Devoteam Knowledge Services)

Overlayer began as a lightweight Google Workspace companion for leveraging internal company knowledge with AI, and the same extension is now distributed by the consultancy Devoteam under the name Devoteam Knowledge Services. Because the Chrome Web Store entry, extension ID and publisher record are unchanged, anyone who installed Overlayer keeps getting updates under the new branding. The extension is aimed at teams that already live inside Google Workspace and want to avoid bolting on yet another search or wiki tool.

The product folds several knowledge-work tasks into a single side panel: AI-powered search across the company's drives and connected sources, automatic tagging of documents as they are created, identification of in-house subject-matter experts, and an approval workflow so that sensitive or reviewed material follows the right process. It is installed with no setup, requires little configuration, and is designed specifically for Google Workspace rather than generic web pages.

The extension reports 8,000 users and a perfect 5.0 rating from a small handful of reviews, with version 4.7.4 as the most recent update. It is published by Devoteam, a European technology consultancy headquartered in Levallois-Perret, France, which gives it the backing of an established services organization rather than an anonymous solo developer.

**Pricing & Plans:** The Chrome extension is free to install and use within your Google Workspace tenant; enterprise rollout, governance and support terms are handled through Devoteam. The Chrome Web Store listing does not publish a per-seat price, so check with Devoteam for organizational licensing.

- **AI search over internal knowledge:** Ask natural-language questions and get answers pulled from your company's drives and connected knowledge sources, without leaving Google Workspace.
- **Automatic tagging:** Documents are tagged as they are created so content stays findable and consistently categorized across the organization.
- **Approval workflows:** Route sensitive or reviewed documents through a built-in approval process to keep published knowledge trustworthy.
- **Expert identification:** Surfaces the in-house colleagues who know a topic best, turning search results into a route to the right person.
- **Zero-setup Google Workspace design:** Installs in seconds and is built exclusively for Docs, Drive, Gmail and the wider Google suite.

**Strengths:** Runs entirely inside Google Workspace, so there is no new tool for employees to learn; Combines AI search, tagging, expert finding and approvals in one extension; Backed by Devoteam, an established European consultancy with a verified developer profile; Very small footprint and effectively no setup time

**Limitations:** Pricing and enterprise terms are not published on the store listing; Only relevant if your organization is standardized on Google Workspace; Review volume is tiny, so independent quality signals are limited

## GitBook

GitBook has evolved from a simple Git-based writing tool into a full documentation platform built around accuracy. Teams design and publish docs in a block-based editor, keep them in sync with source control, and use AI to make sure readers and agents always get the right answer. Its headline promise is that the docs platform should flag outdated content and then help fix it, rather than only making content machine-readable.

The workflow combines familiar docs-as-code habits with modern AI. You can connect a GitHub or GitLab repository and treat documentation like software, branching, reviewing, and merging changes. On top of that, GitBook Agent can write, edit, and update pages, while AI Insights tracks where readers and agents get stuck so you know what to improve next. AI Assistant turns your docs into an interactive support surface that answers questions in context.

For AI consumption, every published GitBook site automatically generates an MCP server and ships with LLM optimizations, so coding assistants and other agents can read and trust your documentation. With SOC 2, ISO 27001, and GDPR compliance, SAML SSO, and authenticated access options, GitBook targets both startups and enterprise documentation teams that need security and control alongside speed.

**Pricing & Plans:** GitBook is freemium. A Free plan covers individuals. Essential starts at $65 per site/month and Ultimate at $249 per site/month (billed annually), with additional team members at $12 per user/month. Monthly billing runs $79 and $299 per site/month with users at $15. Enterprise pricing is custom, and AI credits can be purchased in bundles.

- **Block-based editor:** Write with a block-based visual editor, reusable content blocks, and custom components that keep large docs consistent.
- **Git Sync and docs-as-code:** Sync a GitHub or GitLab repo and branch, review, and merge documentation changes like pull requests.
- **AI Assistant:** Readers can ask your docs questions directly and get contextual answers pulled from your content.
- **Stale content detection:** GitBook scans for content that no longer matches your product and flags it for review before wrong answers spread.
- **AI insights and analytics:** See where users and agents get stuck, which answers were given, and which pages to fix first.
- **AI-ready publishing:** Every published site becomes an MCP server, connects via WebMCP, and includes LLM optimizations for AI agents.

**Strengths:** Free plan and 14-day trials make it easy to evaluate; Docs-as-code workflow with real Git branching and review; AI features directly target stale and inaccurate content; Strong enterprise security and compliance credentials

**Limitations:** Per-site plus per-user pricing can add up for larger teams; Some advanced AI features are gated to the Ultimate tier; Building a custom theme still assumes some technical comfort
