## Hermes-Agent

Hermes-Agent is the officially published agent from Nous Research, distributed free and open source under the MIT license. Rather than a single chat window, it is designed as a long-lived assistant that persists conversations, memories, and self-authored skills between sessions, so solved problems become reusable capabilities instead of one-off prompts. The desktop app and install script support macOS 12+, Windows 10/11, and most Linux distributions.

Its reach is deliberately broad. One agent and one shared memory can connect to Telegram, Discord, Slack, WhatsApp, Signal, email, and the command line, so the same assistant follows you across surfaces. Beyond conversation it can browse and automate the web, use vision, generate images and speech, and reason across multiple models, while isolated subagents handle delegated work with their own terminals and Python RPC scripts to keep the main context light.

Automation and safety are first-class: natural-language scheduling runs recurring reports, backups, and briefings unattended through the gateway, and sandboxing is available across five backends including local, Docker, SSH, Singularity, and Modal with container hardening and namespace isolation. The core agent is free; model providers and optional hosted services are billed separately, and Nous Portal offers usage-based cloud agents in addition to free and low-cost tiers.

**Pricing & Plans:** The Hermes-Agent software is free and open source under the MIT license; model providers and optional hosted services are billed separately. Nous Portal offers a free pay-as-you-go tier plus Plus, Super, and Ultra cloud plans with usage, hosted tools, and cloud hosting, so you can bring your own keys or pay for managed credits.

- **Persistent memory and self-written skills:** Hermes keeps conversations, memories, and skills between sessions, and turns solutions it has already found into reusable capabilities you can call again.
- **Every surface in one agent:** Connect Telegram, Discord, Slack, WhatsApp, Signal, email, and the CLI to a single agent with one shared memory, so context follows you across platforms.
- **Natural-language scheduling:** Describe recurring reports, backups, or daily briefings in plain language and let them run unattended through the gateway.
- **Subagent delegation:** Spawn isolated subagents with their own conversations, terminals, and Python RPC scripts to run zero-context-cost pipelines in parallel.
- **Flexible sandbox backends:** Run untrusted work in local, Docker, SSH, Singularity, or Modal environments with container hardening and namespace isolation.

**Strengths:** Genuinely free and MIT-licensed, with no mandatory subscription to use the core agent; Persistent memory and auto-generated skills make it compound in usefulness over time; Unusually wide platform reach for a single agent, from Telegram to the command line; Multiple sandbox backends and subagent isolation suit serious automation work

**Limitations:** Self-hosting and provider setup demand real technical comfort compared with hosted chat apps; You bring your own model provider keys or pay for Nous Portal credits, so costs vary; Cloud hosting capacity per tier is modest, which can limit heavy always-on workloads

## 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
