Governed AI platform for companies: an employee Workspace with 200+ models, Projects, scheduled no-code agents and approval gates, plus a Gateway API, under one set of admin controls.

nexos.ai is a Vilnius-based AI platform, founded in 2024, that gives a company one governed place to use more than 200 models. It has two halves that share one account: a Workspace for employees and a Gateway API for developers.

In the Workspace, people chat with any model or let Smart Routing pick one, compare models side by side, run deep research, and work in Projects, where uploaded files are chunked, embedded and indexed so answers are grounded in the team's own material.

No-code agents are built by describing a task in plain language: Agent Builder drafts the instructions and a Flow of steps, connects integrations such as Jira, Confluence, GitHub, Slack, Google Workspace and Microsoft 365, and can put the agent on an hourly, daily, monthly or yearly schedule. Before an agent sends a message, creates a ticket or updates a record, a Human-in-the-Loop approval card can pause it for a person to approve or decline, set per integration. Users can keep a personal Memory across chats and agents, and agents can start from pre-made templates or a prompt library organized by department.

For admins, nexos.ai adds roles and teams, SSO-managed accounts, company-wide guardrails with per-model overrides, model settings with fallbacks and trusted models, and an Observability view that shows every API call with its messages, cost and latency, kept for seven days.

The Gateway API offers the same model catalog to code, with management endpoints for teams, users, agents and budgets. nexos.ai states SOC 2 Type II and ISO 27001 certification and hosts the platform and most models in Europe, with an EU gateway for EU-hosted, zero-retention model access. Plans are sold per seat on 1-month or 12-month terms with a monthly credit allowance, API usage runs on separately prepaid credits, and Enterprise is priced through sales. It fits European companies that want employee AI and developer model access under one set of controls; it is not self-hosted.

Integrations

The Gateway API at api.nexos.ai exposes 200+ models through Chat, Anthropic-native Messages and Responses endpoints plus management APIs for teams, users, agents, budgets and usage, with guides for Claude Code, Codex CLI, CrewAI, LangChain, LangGraph, OpenAI Agents SDK, Vercel AI SDK, n8n and Langfuse. Workspace agents connect to Atlassian, GitHub and GitLab MCP servers, Google and Microsoft 365 apps, Slack, HiBob, Looker and BigQuery, and nexos.ai is reachable from Slack, Microsoft Teams, Telegram and WhatsApp.

In practice

Employees across a company paste sensitive data into a dozen public AI tools. nexos.ai replaces the sprawl with one Workspace where every model runs under company-wide guardrails, roles and teams, and admins can review each call in the Observability logs.

A team lead wants a Monday summary of Jira, Slack and email action items without asking for it. They describe the task to Agent Builder, connect the integrations and set a weekly schedule, with an approval card before the agent posts anything.

An online retailer needs four million product descriptions optimized. A reusable agent grounded in the company's own files in a Project does the per item work the company reports as far cheaper than manual effort.

Integrations & Tool Calling Full

Workspace Integrations reach Google Drive, Mail and Calendar and Microsoft Outlook, OneDrive, SharePoint, Teams and Calendar on the productivity side, Atlassian, GitHub and GitLab through their MCP servers, and Slack, HiBob, Looker, Google Ads and BigQuery. Organization admins activate them and each user connects through the provider's own sign in. The approvals page documents agents taking write actions through these integrations (sending a message, creating a ticket, updating a record), so agents take authenticated action in outside systems.

Workflow Orchestration Partial

A visual Flow in Agent Builder shows the steps an agent will take to complete its task, with optional human in the loop review steps, and agents run multi step work across connected tools on demand or on a schedule. No deterministic nodes, branching or multi agent handoff are documented.

Sourcedocs.nexos.ai/workspace/agents/agent-builderread 2026-09-22

Knowledge Grounding & RAG Full

Files added to a Project are chunked, embedded and stored in the Project's context index, and nexos.ai uses Retrieval-Augmented Generation to pull relevant context from them when answering; Projects can be shared with view or edit access. Agents take files from a Project as their knowledge base to give sourced answers, and that knowledge can be updated or removed at any time. New customer knowledge enters a persistent index without retraining, so the retrieval structure scales past the context window and stays queryable.

Sourcedocs.nexos.ai/workspace/projectsread 2026-09-22

Human Oversight & Guardrails Full

Before any action that changes something in another tool, such as sending a message, creating a ticket or updating a record, Human-in-the-Loop Approvals pause the agent and show an approval card naming the action, the integration and its key details. The person approves (the agent acts and continues) or declines (the action is not taken and the run stops). Approvals appear in the conversation for chat agents and in Activity history for scheduled agents, and are switched on per integration inside each agent's settings.

Sourcedocs.nexos.ai/workspace/agents/human-in-the-loop-hitl-approvalsread 2026-09-22

Security, Identity & Governance Full

Access is managed per user: organization admins invite, update and remove users and assign each a role and team (Users page), accounts can be managed through the customer's identity provider with linked SSO sign in (Account page), and company wide guardrails with per model overrides and exclusions apply across the workspace (changelog). nexos.ai's integrations and EU gateway pages state SOC 2 Type II and ISO 27001 certification, with reports in its Trust Center.

Sourcedocs.nexos.ai/workspace/settings/organization/usersread 2026-09-22

Observability & Auditability Full

Every API request is recorded in Observability: which model was used, latency, cost, token usage and errors, with full request details, and admins can drill into a call to see the exact messages and responses, filtering by time, model, user or team. A Metrics dashboard shows usage, cost and health, and the changelog adds log spans. Scheduled agents keep an Activity history of their runs and approvals, and retention is stated.

Sourcedocs.nexos.ai/workspace/settings/observabilityread 2026-09-22

Memory & State Persistence Partial

User Memory keeps context about each user across chats and agents: the app adds context as the user works, and the user can view saved memories, edit them, delete one or all, or turn Memory off, alongside personalization details and custom instructions the user writes. The scope is stated (per user, in Chat and Agents) and the user can delete their own entries, but no lifetime is stated.

Deployment & Data Residency Partial

Europe hosts the platform and most available models, according to nexos.ai's own pages, and its EU gateway runs Claude, GPT, Gemini and Mistral EU hosted with zero data retention. That is a stated residency commitment, but no named region list, named customer environment option or selection surface is documented.

Sourcenexos.ai/eu-gatewayread 2026-09-22

Prebuilt Agents, Templates & Packs Full

Ready made assets are there to adopt: the changelog's AI Agents entry lets users start from premade templates, the pricing FAQ lists an extensive template library in every plan, and the docs publish a prompt library of assistant instructions organized by department, such as a product strategy evaluator.

Sourcedocs.nexos.ai/workspace/agents/prompt-libraryread 2026-09-22

Triggers & Channel Coverage Full

A schedule can be set on an agent (hourly, daily, monthly or yearly), per the changelog entry Agent Builder and Scheduling, so it runs automatically in the background with no person initiating it. The Agent Builder page describes agents set to run periodically, such as a morning summary of Slack updates, and scheduled runs appear in the agent's Activity history. Agents are also reachable from Slack, Microsoft Teams, Telegram and WhatsApp.

Sourcedocs.nexos.ai/changelog/changelog/latest-updatesread 2026-09-22

Model Flexibility & Routing Full

Users pick any of 200+ models per chat, Project or agent, or let Smart Routing choose, and organization admins add models with their own guardrails, timeouts, ordered fallback models and a trusted-model badge. The Gateway API exposes the same catalog to the customer's code, so model choice sits with the customer.

Sourcedocs.nexos.ai/workspace/settings/organization/modelsread 2026-09-22

APIs, SDKs & MCP Extensibility Full

A Gateway API at api.nexos.ai is documented with a published OpenAPI reference: Chat, Anthropic native Messages, Responses, audio, images, embeddings and storage endpoints, plus management endpoints for teams, users, agents, assistants, company API keys, budget limits and usage, with Python, Go and .NET code examples. Agents can be managed from outside through it.

Sourcedocs.nexos.ai/gateway-apiread 2026-09-22

Testing, Debugging & Optimization Partial

Models can be compared side by side on the same prompt in nexos.ai Chat, and the changelog adds the customer's own assistants to Compare Models to test them against other models on performance and output differences; Agent Builder has a Try Agent window for testing on real scenarios before launch. These let a person inspect and compare an agent's outputs by eye. No scored test cases, pass rate, judge verdict, quality gate or optimization loop is documented.

Sourcedocs.nexos.ai/workspace/chatread 2026-09-22

Browser & Computer Use Partial

Web pages are fetched and analyzed by the Web Scraper, which per the changelog processes URLs found in web search results, uploaded files and agent instructions, so agents continue tasks without a person supplying the link. That is a headless fetch; no hosted browser, desktop session or remote computer control that an agent drives is documented.

Recent platform changes

2026-07-17·MCP / tool calling / APIVerified

nexos.ai introduced an Anthropic-native Messages API endpoint that accepts requests in Anthropic's wire format and forwards them byte-for-byte to the provider. This update ensures that native Anthropic features, such as cache_control markers for prompt caching, are preserved rather than stripped by intermediate translation layers.

Pricing

1-month and 12-month self-serve plans per seat; Enterprise custom through sales

Per seat on 1-month or 12-month plans, each seat with a monthly credit allowance; Gateway API usage on separately prepaid credits; Enterprise terms custom

Trial available

What is public

The plan structure is public: 1-month and 12-month plans for individuals and small to mid-sized teams, and Enterprise on custom terms. The docs state each seat includes up to 3,000 credits a month unless agreed otherwise and API credits cost €1 each; seat rates are not stated in the docs.

Billing mechanics

Seats are bought on 1-month or 12-month plans and managed from the Billing page, where owners add or remove users. Each seat includes a monthly credit allowance spent across all models at each model's rate. Gateway API access is a separate prepaid add-on: credits bought at €1 each, used until the balance reaches zero. Enterprise agreements are customized through sales.

Cost watchouts

Credits are consumed faster by more capable models and longer requests, so heavy use can exhaust a seat's monthly allowance and prompt an upgrade or extra credits. Gateway API usage is billed separately from seats on prepaid credits and stops when the balance reaches zero. Request logs are kept for 7 days.

Variable cost rationale

No public rates exist. The FAQ describes plan based subscriptions rather than pure usage billing, and the Gateway includes cost control features like intelligent caching and spend controls that push against usage growth, but underlying model consumption routed through the Gateway remains workload driven, especially with bring your own keys where provider costs bill separately.

Additional watchouts

Budget both the seats and the API credits if developers will use the Gateway API, since API access is not included in a seat. Watch credit burn on premium models against the per-seat allowance.

Overage / add-ons

Going past plan limits prompts an upgrade or the purchase of extra credits; API usage has no hard cap and stops when prepaid credits run out.

Sales call required

Mixed (some tiers require a call)

Free / trial

Free trials for companies (docs changelog); every plan carries a 14-day money-back guarantee

Key ambiguities

Seat rates are not stated in the docs. A promotional nexos.ai offer page shows euro prices for 1-month and 12-month plans with 1,000 monthly credits, while the docs state up to 3,000 credits per seat; the current rate card sits on the pricing page.

Missing data

Seat price per plan and any Enterprise seat minimum are not stated in the docs.
