Frequently Asked Questions

Image files and certain tool calls (eg web fetch) can consume a lot of tokens.

To check your session size, use /usage — this toggles a usage summary on each message.

You can compact a session with /compact, or clear it with /new or /reset.

To check usage once without toggling, use /status.

Ask Klaus directly: "How much have I spent?" or "Show me my usage stats."

Klaus can break down your spending by model, show which ones are consuming your credits, and display your remaining balance.

You can also use /credits to quickly check your OpenRouter balance.

You're out of tokens on OpenRouter. Go to the Billing page to buy more tokens or add your own OpenRouter key.

OpenRouter treats all Klaus accounts as a single user, so free-tier rate limits are shared across everyone.

This means free models will be heavily throttled, especially during peak times.

If you want to make heavy use of free models, we recommend setting up your own OpenRouter API key (BYOK) on the Billing page — this gives you your own rate limits.

We're working with OpenRouter to resolve this on our end.

This means the conversation is too long for your current model. Two common causes:

1. You switched to a model with a shorter context window than before.

2. You don't have enough OpenRouter credits to pay for such a long prompt — add more credits on the Billing page.

To fix it, either switch to a model with a longer context window, add more credits, or start a fresh session with /new or /reset.

Email us at support@usebits.com and we'll fix this for you.

You can fix this from klausai.com/klaus — use the model selector dropdown to choose a valid model.

This will update your instance configuration without needing to access the command line.

Starter runs on t4g.small — 2 vCPUs, 2 GB RAM, and 30 GB of encrypted storage.

Plus runs on t4g.medium — 2 vCPUs, 4 GB RAM, and 60 GB of storage.

Pro runs on t4g.xlarge — 4 vCPUs, 16 GB RAM, and 100 GB of storage.

Yes. Go to the Integrations page and set up Tailscale. Once connected, you'll get an SSH command like ssh root@your-hostname.

Yes. You can enable browser automation from the Integrations page. This installs Chromium on your instance and gives Klaus the ability to browse the web, take screenshots, and interact with web pages.

By default, you can use any model which OpenRouter supports, which is almost any AI model.

We recommend Haiku 4.5, Gemini 3 Flash, and Kimi k2.5. If you're stuck, use Opus 4.6.

If you connect your ChatGPT subscription, you can also use OpenAI models (like GPT-5.4) at no extra cost — usage is covered by your subscription.

We provide $15 of tokens one-time, after which you can buy more OpenRouter credits directly on our website at klausai.com/klaus.

See our pricing page.

We support Slack, Telegram, WhatsApp, and iMessage directly. Discord is also very easy to set up.

Go to the Integrations page to connect any of these.

WhatsApp connections are inherently unstable. There are two common issues:

1. **Session expiry:** WhatsApp sessions expire every 30 days — this is a limitation on WhatsApp's end. When it happens, go to the Integrations page and re-pair by scanning the QR code again.

2. **Periodic disconnections:** The WhatsApp Web protocol can drop connections during quiet periods, which may cause missed messages. This is an upstream issue in the WhatsApp provider that we're unable to fix on our side.

For more reliable messaging, we recommend using Slack or Telegram instead.

See the AgentMail integration docs.

Click the "Get Help" button in the chat sidebar — this lets you report issues or request support directly.

If your instance isn't responding, the Get Help button can also trigger the automated troubleshooter to diagnose and fix common problems.

AI can help you fix bugs and build new features from within our Discord in the #talk-to-klaus channel.

To talk to a human, post in the #help channel in Discord or email support@usebits.com.

Klaus runs on a private subnet on AWS. Adding a firewall won't increase security, and you might lock yourself out of your instance.

The things we're working on most urgently are:

Klaus is our hosted deployment of OpenClaw, and our main focus right now.

Bittie is a previous browser agent project that we are no longer spending much time on.

But that part of our website is still alive because we still have users and want to support them.

If you're here to use OpenClaw/Klaus, you can entirely ignore the Bittie section of our UI.

Yes. Go to the Integrations page and click on Google.

If you're already logged in with your own account, click the three dots to disconnect first.

Then when Google prompts you to log in, make sure you log in with your agent's Google account.

When you connect Google, you may see a screen that says "Google hasn't verified this app."

This is normal — it appears because our Google OAuth app is still going through Google's verification process.

To continue, click "Advanced" and then "Go to Klaus (unsafe)." Despite the wording, your data is safe — Klaus only requests the permissions shown on the consent screen, and you can revoke access at any time from your Google Account settings.

Go to the Integrations page and enable the Google Workspace integration.

This lets Klaus access your Google Calendar, Gmail, and Drive.

You'll get an email alert when your credits are running low.

If you have auto-refill enabled, credits top up automatically so Klaus never stops mid-task.

You can enable auto-refill from the Billing page.

Yes. You can enable the GitHub backup integration from the Integrations page.

Klaus will sync files and code to a GitHub repository you specify.

The Browser Relay extension lets Klaus control your Chrome browser directly.

Unlike server-side browser automation (which runs Chromium on your instance), Browser Relay uses your own browser session — so Klaus can access sites you're logged into.

Install the extension from the Chrome Web Store and connect it from the Integrations page.

Yes. You can create a custom Slack app with your own icon and name.

Go to the Integrations page and look for "Custom Slack App".

The Canvas page shows HTML files that Klaus has created for you.

These can be interactive web apps, charts, or visualizations.

Note: Canvas files don't send data back to Klaus — they're view-only.

Files should be placed in ~/.openclaw/canvas/ (not ~/.openclaw/workspace/canvas/).

The troubleshooter is an automated repair system that diagnoses and fixes common issues with your Klaus instance.

It checks gateway health, disk space, memory, and service status — then attempts to fix any problems it finds.

We run it automatically when your instance fails a health check, but you can also trigger it manually from the Klaus Health page.

Go to the Klaus Health page to see past troubleshooter runs and your instance health status.

You can also manually trigger a troubleshoot from there if something seems wrong.

Yes. If you have a ChatGPT Plus or Pro subscription, you can connect it to Klaus so that OpenAI model usage (like GPT-5.4) is covered by your subscription instead of per-token billing.

Go to Settings → Billing, find "ChatGPT Subscription", and click "Connect ChatGPT."

You'll be given a code to enter at OpenAI's verification page. The code is auto-copied to your clipboard.

Once connected, the model selector will show only OpenAI models available through your subscription.

Go to Settings → Billing and click "Disconnect" under the ChatGPT Subscription section.

Klaus will switch back to using OpenRouter credits and show the full model list again.

Go to the Integrations page and find "iMessage." Enter your phone number and verify it via SMS.

Once connected, you can text Klaus from your iPhone and get responses as iMessage messages.

Klaus will show typing indicators while composing a reply and supports emoji reactions.

On the chat page, you can paste an image from your clipboard (Cmd+V) or drag and drop a file onto the chat input.

Klaus will analyze the image and respond based on what it sees. We don't support PDFs, csvs, or other filetypes yet.

Yes. Go to the Sessions page and use the search bar to search across all your chat transcripts.

Matching terms are highlighted in the results so you can quickly find what you're looking for.

Yes. The File Explorer on your instance page lets you browse, view, and edit files directly from the dashboard.

You can also manage agent configuration files from the Agents page.

Scheduled tasks (cron jobs) let Klaus run prompts on a schedule — like daily reports or periodic checks.

Go to the Scheduled Tasks page to create, edit, or delete tasks. You can configure the prompt, model, schedule, and delivery channel (e.g., Slack, Telegram).

Yes. Enable the webhook on your AgentMail integration and incoming emails will be forwarded to your agent automatically.

You can choose which agent handles the responses if you have multiple agents configured.

Yes. On the AgentMail integration card, you can switch to "Bring Your Own Key" mode and enter your own AgentMail API key.

This gives you full control over your email configuration and lets you use your existing AgentMail account.

Yes. The Outlook Email integration connects any IMAP/SMTP email account — including Outlook, Yahoo, and other providers.

Go to the Integrations page to set it up.

Klaus has semantic memory search powered by OpenRouter embeddings.

It can search through past conversation history to recall previous discussions, making it better at maintaining context across sessions.

Yes. Your instance disk is backed up daily via automatic EBS snapshots.
