## Keymate.AI

Keymate.AI positions itself as "your AI memory" for knowledge workers in marketing, ops and sales. You add the sources you work with daily — PDFs, Google Docs, YouTube videos, web pages and emails — and organize them by project or campaign. Keymate then builds an embedding-based memory you can search and question in natural language, with answers scoped to just the sources you select so you avoid generic or hallucinated responses.

The product works in two places. There is a standalone Keymate web workspace for uploading, annotating and searching your content, and there is a ChatGPT integration (a GPT and, historically, a plugin) that lets ChatGPT draw on your Keymate memory while you chat. An email-linking feature auto-saves messages into searchable memory, and a Make.com integration lets you run automations over your Keymate data.

Security is a headline part of the pitch: Keymate states it is SOC 2 and HIPAA compliant and stores embeddings in an enterprise-tier vector database on AWS and Azure. Data is encrypted in transit with at least TLS 1.2 and at rest through cloud-provider defaults, and each user's memory is isolated. The team says it has helped more than 250,000 professionals and reports over 10 million AI operations.

**Pricing & Plans:** Freemium. A free Essential tier includes 15 credits per week, Google-powered search and limited memory building with ads. Paid monthly plans are Bronze at $5, Silver at $10 and Gold at $20, scaling credits, memory word limits, PDF upload and the API for custom apps and GPTs. Annual billing is also offered.

- **Personal AI memory / knowledge base:** Upload PDFs, Google Docs, web pages, YouTube links and more, then build a private, searchable memory you can query in plain language.
- **Answers scoped to your sources:** Responses are grounded only in the files you select, so you can search across everything or narrow the scope to a single collection and reduce guesswork.
- **Inside ChatGPT and a web app:** Use Keymate as a standalone workspace or bring your memory into ChatGPT via the GPT/plugin so your chats can reference your own content.
- **Shared team collections:** Create shared libraries so teammates collaborate on the same AI-powered sources and align faster on a common knowledge set.
- **Email linking, automation and API:** Auto-save emails into searchable memory, wire Keymate into Make.com automations, and call the API from custom apps and GPTs.

**Strengths:** Memory is grounded in your own curated sources rather than generic model output.; Works both as a web workspace and inside ChatGPT, so it fits existing chat habits.; Clear enterprise security posture (SOC 2 / HIPAA compliance claims, encrypted storage, isolated memories).; Team-shared collections and email/automation integrations extend it beyond personal note-taking.

**Limitations:** Credit-based limits mean heavy memory use can require higher-priced plans.; Feature availability can differ between the web app and the ChatGPT integration.; Best value depends on committing to one of several tiers rather than a single simple price.

## 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
