What Casper does

Not a chat with a model. An assistant that finishes the task.

Your assistant does the work

Set a goal. Casper plans it, picks the right models, runs the tools and hands you the finished result.

  • Read the brief
  • Research competitors
  • Draft the deck
  • Render charts
  • Send to Gmail

29 models, one assistant

GPT, Claude, Gemini, Grok, DeepSeek and Perplexity. Casper chooses, you get the answer.

Files, code and documents

Upload anything. Casper reads it, runs code and returns a finished document, table or chart.

df = read_excel("report.xlsx")

# done: summary.pdf, chart.png

Images and video

Frequently asked questions

The short version: limits, models, payment and your data.

ChatGPT is one model. Casper is an assistant on top of 29 models: it picks the best one for each step, runs tools, works with your files and apps, and remembers your context. You describe the task and Casper brings back the result.

Your plan comes with a monthly pool of credits, and every request spends them: a short chat message costs a fraction of a credit, a video costs far more. The plan also decides which models and features are open to you. The exact numbers are on the plans page, and you can top up credits at any time.

Yes. In any chat you can pick a specific model instead of Casper: GPT, Claude, Gemini, Grok, DeepSeek, Perplexity, plus the image and video models. Casper is the default, not a requirement. Which models you get depends on your plan: Free has the basic tier, Plus adds the standard models, Pro unlocks all of them.

Yes. All requests go through our own servers, so you don't need a VPN. Payment works with Russian cards, Telegram Stars and Stripe.

Yes. Gmail, Google Calendar and Drive, GitHub, Notion, Linear, Jira, GitLab, Figma, HubSpot, Yandex Wiki and 16 more are in the catalogue. You can also add any MCP server by URL.

Yes, in one click from your account. You keep access until the end of the paid period.

Your conversations and files stay yours. We don't sell them and don't train models on them.
