Crowdin Copilot — Your AI Teammate for Localization

Meet your AI-powered co-worker, built directly into Crowdin. Crowdin Copilot brings AI intelligence into every corner of your localization workflow — from the Editor to project management to org-level automation.

Overview

Crowdin Copilot is an AI assistant that lives where you work. Instead of switching between tabs and copy-pasting context into a chat window, Copilot is embedded natively inside Crowdin — and it already knows exactly what you're looking at, what you're working on, and what your project needs.

With direct access to Crowdin's full API surface, Copilot isn't just a chat window. It's a capable, configurable AI teammate that can read your projects, answer questions, and take action — all while keeping you in control.

Core Capabilities

Two Agents, One Purpose: Safe & Powerful Automation

Crowdin Copilot ships with two built-in agents designed for real-world localization workflows:

• Ask Agent — A read-only companion. Query your project stats, review string statuses, explore translation memory, generate reports — all without risk of unintended changes. Ask will redirect you to Task whenever it detects a write operation.
• Task Agent — Full read + write access to Crowdin. Create tasks, trigger pre-translation, upload files, manage workflows. Before any irreversible action, it pauses and asks for your confirmation — so automation never runs ahead of you.

Deep Editor Integration

When you're working in the Crowdin Editor, Copilot sees exactly what you see:

• The active string and its source text
• All existing translations across languages
• Votes, approvals, and QA flags
• Your current workflow step and task assignment
• The full page of strings in context

Ask "Does this string have consistent translations across all languages?" and Copilot already knows the answer — no copy-pasting required.

Copilot sees your active string, existing translations, and workflow context in real time

Custom Agent Builder (Admin)

Every team has different needs. With Copilot's no-code Agent Builder, admins can create agents tailored to their exact workflow:

• Write a custom system prompt defining the agent's role, tone, and behavior
• Pick exactly which Crowdin tools the agent can access — down to individual operations
• Add tools from any connected external integration
• Clone a system agent as your starting point and customize from there
• Protect translators from accidental changes by creating read-only agents with restricted access

System agents ship out of the box — clone them or build your own from scratch

Fine-grained access control — choose exactly which Crowdin operations each agent can use

External Integrations (Admin)

Extend Copilot beyond Crowdin by connecting external services:

• GitHub and GitLab — access repos, issues, PRs, and code for accurate technical translations
• Linear, Notion, Slack — connect your project management and communication tools
• Sentry, PostHog — bring in error tracking and product analytics context
• Context7 — pull up-to-date library documentation directly into the agent's context
• Add any custom integration your organization uses
• Preview available tools before saving — no guessing what a service exposes
• All integration tools are automatically surfaced in the Agent Builder

Connect external services and instantly surface their tools inside any agent

Human-in-the-Loop by Design

Copilot never acts without accountability. When the Task agent is about to do something significant, it pauses and asks for your confirmation before proceeding — radio buttons, checkboxes, or a free-text reply. Every consequential decision remains yours.

Before any critical action, Copilot pauses and asks for your confirmation

Chat Interface

Context-Aware Session History

• Every conversation is saved with an auto-generated title
• History is scoped to where you are in Crowdin — Editor, Project, Organization, or Profile
• Resume any past conversation exactly where you left off

Session history scoped to your current context — pick up any conversation right where you left off

Real-Time Task Visibility

When Copilot plans a multi-step task, its plan is surfaced live above the input — showing each step with a pending / in-progress / completed indicator. You always know what the agent is doing and what comes next.

Multi-step plans are surfaced as a live queue — full visibility into what the agent is doing

Full Transparency on Every Action

Complex operations are broken down into individual steps, each visible and expandable in the chat. You can see exactly what Copilot did — and why. No black boxes.

Model Selection & Theme Sync

• Switch between AI models mid-conversation — your preference is saved automatically
• Dark mode syncs in real time with your Crowdin theme

Switch models anytime — your choice is remembered for the next conversation

Usage Limits & Context Window

Crowdin Copilot displays a real-time usage and cost indicator next to the chat box.

• Context Window: 200,000 tokens. Context window is ashort-term memory of your current chat. The progress bar shows how much information the AI is currently “holding in mind”. If the percentage gets very high, starting a new chat will reset the context and help the AI focus better on new tasks.
• Limits: We have implemented a $5 per-request safety limit. If a task becomes highly complex and reaches this amount, the Copilot will pause and notify you. You can then send another message to confirm you’d like to continue, ensuring there are no unexpected cost spikes for a single action.

Data Security & Privacy

Your data remains yours. Crowdin Copilot is designed with enterprise-grade security in mind:

• No Training on Your Data: Your project content, translations, and interaction history are never used to train the underlying AI models.
• Enterprise-Grade Privacy: Crowdin ensures that your proprietary strings remain secure and are handled according to zero-data retention policies where supported by the AI provider.
