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 auto-translation, upload files, manage workflows. Before any irreversible action, it pauses and asks for your confirmation — so automation never runs ahead of you.

Describe Your AI Pipeline, and Copilot Builds It

Instead of assembling a multi-step AI Pipeline field by field, describe what you want in plain language. Copilot reads your project first — languages, the file types you actually have, whether screenshots are tagged — and only offers steps your project can support. Then it asks a few short questions about ambiguity filtering, QA checks, and language-specific rules.

Nothing is created until you approve it. You get a plan of the whole pipeline, every step with its scope and model, and Copilot validates the configuration before saving — so a broken pipeline doesn't surface halfway through a run.

It works on existing pipelines too: add a step, drop one, reorder them, or reuse a pipeline that already does what you described.

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 also reads the AI context stored on your strings, including context written by apps like Cursor — so an explanation added once benefits every conversation afterwards.

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

Teach Copilot Your Team's Skills (Admin)

Out of the box, Copilot knows how to work with projects, strings, and translations. What it can't know is your way of doing them: how you build a glossary, the house style for release notes, the checklist a new locale goes through before launch. A skill captures that knowledge once, so nobody has to re-explain it in every chat.

• Write a skill from scratch, upload a SKILL.md file, or import directly from skills.sh, GitHub, or GitLab
• Same Agent Skills format that coding agents use — bring along the skills your team already maintains
• Assign a skill to one or more agents, and every user in the organization benefits automatically
• Copilot pulls a skill in when the conversation calls for it, or you can invoke one explicitly with a / command in chat
• Only admins can create, edit, or remove skills — everyone else just notices that Copilot got better at your workflows

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

Copilot Beyond the Chat

Copilot isn't only the panel on the right. It's built into the screens where localization assets get created, so you never start from a blank form:

• Glossaries — on the glossary creation screen, click Create with Copilot. It asks a few quick questions about your content and where to pull terms from, then starts extracting terminology right away.
• Style guides — Generate with Copilot runs the same guided, question-and-answer setup, and drops the result into an editor that's already open and ready to edit.

Copilot Skills

Skills are focused instruction sets that load automatically when a request matches them — so Copilot reaches for the right Crowdin operation with the right options instead of guessing. System skills ship with Copilot; nothing to install.

• String Management — adds, edits and removes source strings, picking the call that keeps existing translations and approvals intact.
• AI Pipeline Prompt Design — designs and edits the ordered passes an AI Pipeline makes over your strings, and keeps it from paying twice for the same check.
• AI Pipeline Pre-translation — runs AI Pipeline auto-translation and enriches string context along the way.
• Cross-Project Search — read-only search that locates strings, translations, files and branches by text across every project in your organization.
• Style Guide Creation — drafts a style guide from your real bilingual content — tone, punctuation, dates, button labels — plus the compact AI instructions auto-translation reads.
• Glossary Terms Extraction — mines source content for glossary candidates, sorts them into brand, feature and domain terms, and adds them in reviewed rounds of ten.

Chat Interface

Work Without Waiting

Working with Copilot no longer means sitting and watching it type:

• Send while Copilot is working. Type at any point during a response and Copilot picks your message up as part of the task it's already running, attachments included. A correction lands while it still matters, instead of after the work is finished the wrong way.
• Queue what should wait. Press Ctrl/Cmd+Enter and your message joins a visible queue in the message box, where you can edit, reorder, or remove it before its turn. Line up three tasks, then walk away.
• Completion sound. Turn it on and Copilot lets you know when it has finished a reply while the chat isn't in focus — so you can start something long and go do your own work.

Voice Input

Click the mic button next to Send — or press Ctrl/Cmd+Alt+V — and talk. Your speech becomes text as you go, so you can describe a task the way you'd explain it to a colleague instead of typing it out. It runs on your browser's built-in speech recognition, so nothing extra to install.

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.
• Budget caps: Beyond the per-request limit, the Limits tab in your AI settings lets you set daily and monthly spending caps for the whole organization, a default per-user baseline, and higher overrides for specific users. No surprise bills from a large-scale run.
• Spend visibility: The AI Tokens Usage report shows what every token was spent on — the action that triggered the request, the application behind it, and an estimated cost in USD. Export it as JSON or CSV for any date range.

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.
• Auditable by Default: The Logs tab in your AI settings keeps a history of every AI call routed through the platform for the last 30 days, successful or failed — so you can audit activity and troubleshoot provider errors.
