A Google or Microsoft account. No credit card required for the free plan. ### Can I use Crew without connecting any services? Crew requires a Google or Microsoft account to sign up. When you sign up, basic services (email, calendar, drive) are automatically connected. You can disable specific tools in Settings if you don't want Crew to access certain services. ### Which messenger should I connect first? Choose the messenger you use most frequently. If you're not sure: * **WhatsApp** for everyday personal use * **Slack** for work use * **Discord** for community-oriented users * **Telegram** for tech-savvy users (you get your own bot) ## Chat & Usage ### How long does Crew remember our conversation? Within a single conversation thread, Crew remembers everything. For information across conversations, use the **Memory** feature — tell Crew to "remember" important details. ### Can I use Crew in my language? Yes! Crew supports 14 interface languages and can converse in virtually any language. Change the interface language in Settings → Language. For conversations, just type in your preferred language and Crew will respond accordingly. ### Is there a message length limit? There's no strict limit, but extremely long messages use more credits. For best results, be concise and specific. ### Can I undo a sent message? No, once a message is sent, it can't be undone. If Crew sends an email or performs an action you didn't want, ask it to follow up with a correction. ## Tools & Features ### Why can't Crew access a specific tool? Check these things: 1. **Is the tool enabled?** Go to Tools and make sure the toggle is on 2. **Is the service connected?** Tools like Gmail require a Google connection 3. **Is it available on your plan?** Some tools have plan restrictions (see [Plans & Pricing](/billing-and-plans/plans-and-pricing.md)) ### Can Crew send emails without my approval? Yes, if the Gmail/Outlook tool is enabled and you ask Crew to send an email, it will send it. If you want to review first, ask Crew to "draft" the email instead of "send" it. ### Are my files safe? Yes. Files uploaded to Crew are stored in encrypted cloud storage. They are only accessible through your account and are never used to train AI models. ### Can Crew access my entire email inbox? Crew can search and read your emails, but it only does so when you ask (or when proactive modules are configured to do so). It doesn't passively scan your entire inbox. ## Messengers ### Can I connect the same messenger from multiple devices? Yes! Once connected, you can message Crew from any device where you use that messenger — phone, tablet, desktop. ### Can other people see my Crew conversations on the messenger? No. All messenger conversations with Crew are private 1-on-1 chats (DMs). No one else can see them. ### My messenger connection stopped working. What do I do? 1. Go to **Messengers** in the web app 2. Check the connection status 3. If it shows an error, try **Disconnect** and then **Reconnect** 4. For Telegram: Make sure your bot token is still valid (check with @BotFather) ### Can I use Crew in a group chat? Currently, Crew works as a 1-on-1 private assistant. It doesn't participate in group chats or public channels. ## Billing & Credits ### What happens if I run out of credits mid-conversation? Crew automatically switches to a lighter AI model (Crew 0.5) so you can continue chatting. Responses will be simpler but functional. ### Do unused credits roll over to next month? Regular monthly credits **do not** roll over — they reset each billing cycle. However, **bonus credits** (from credit pack purchases and referrals) carry over indefinitely. ### Can I get a refund? Contact support for billing issues. Refund policies follow standard SaaS practices. ### Why did a simple question cost so many credits? Credit cost depends on the full context sent to the AI, not just your message. Long conversation histories, multiple tool calls, and detailed system prompts all contribute. Start a new conversation for unrelated topics to reduce context size. ## Privacy & Security ### Is my data used to train AI models? No. Your conversations, files, and connected service data are never used to train AI models. ### How is my data encrypted? * OAuth tokens: AES-256-GCM encryption at rest * All connections: HTTPS/TLS in transit * File storage: Encrypted cloud storage ### Can Crew access my data when I'm not using it? Only if you've enabled **Proactive Intelligence** modules. These modules periodically check your email and calendar to send you insights. You can disable all proactive features in Settings. ### Can I delete my account and all data? Yes. Go to Settings → Billing and follow the account deletion process. All your data, conversations, files, and connections will be permanently deleted. ## Troubleshooting ### Crew's response seems wrong or outdated Crew's knowledge has a cutoff date. For current information, it uses web search. If you need the latest data, ask Crew to search the web explicitly. ### The response was cut off For very complex tasks, Crew may hit output limits. Try breaking the task into smaller steps or ask Crew to continue. ### A tool call failed Occasionally, external services (email, calendar, web search) may be temporarily unavailable. Try again in a few moments. If the issue persists, check your service connections in Settings. ### I'm getting unexpected responses Try starting a **new conversation** (press N). Long conversation histories can sometimes confuse the AI with outdated context.
