## 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

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
