Using Claude 5.5 models with your Focalyst plan

What Anthropic released

Anthropic has released several new models, but the status of some rumored releases needs clarification. Claude Mythos 5.5 has not been publicly announced, though a hidden reference on Anthropic's website once described it for specific research¹. However, several Claude 5.5 family models are officially available.

Claude Fable 5.1 was released on September 1, 2026, and is described as Anthropic's most capable model for demanding reasoning, in-depth research, and long-running coding projects². Claude Opus 5.5, released on September 22, 2026, performs at the level of Claude Fable 5.1 on most tasks and is recommended for complex agentic coding and knowledge work³. It costs 40% less than Opus 5³. Claude Haiku 5.5, released on October 7, 2026, is part of the Claude 5.5 family and is designed for high-volume, cost-sensitive applications².

All current Claude 5.5 models (Opus, Sonnet, and Haiku), along with Fable 5.1, share a 1M-token context window and 128K output tokens². Claude Mythos 5.1 is currently available only to organizations verified through Anthropic's Cyber Verification Program or Life Sciences Verification Program⁴. Its pricing is $10 per million input tokens and $50 per million output tokens⁴.

What a stronger model can do with your own data

When you connect a capable AI model like Claude Opus 5.5 to your Focalyst data, it can amplify your personal productivity. This is not about outsourcing your thinking, but about using AI to extend your capabilities. We call this AI Leverage: using AI to multiply what you can accomplish rather than merely as a shortcut. It is about giving AI appropriate parts of the workflow while retaining human judgment, direction, verification, creativity, and decision-making.

The AI can read your tasks, habits, focus time, countdowns, and notes, including voice note transcripts and summaries. This includes tasks you add with a time or priority, habits you track daily, focus sessions you log, countdowns for important dates, and all your written notes and recorded voice notes. For example, the AI might identify that you consistently schedule demanding tasks during your usual evening wind-down period, suggesting you adjust your task planning for better balance. It can also review your notes from a specific project and help you brainstorm next steps or identify gaps in your research. If you use Focalyst to track your study blocks, the AI can analyze your focus patterns to recommend optimal times for deep work, based on when you are most effective.

Use it to summarize extensive notes or generate ideas for new learning approaches, based on your recorded thoughts. Remember, AI should be an amplifier of your intelligence, not a substitute for it. Use it to work smarter, not to avoid thinking critically about your work.

How to connect Focalyst to Claude

Focalyst Pro users can connect their Claude account to their Focalyst data through our AI connections feature. This creates a powerful personal operating system where your AI assistant understands your real-time progress and plans, helping you apply AI Leverage to your daily routine. This integration means your AI isn't guessing; it is working with a real-time snapshot of your commitments and progress.

To connect:

1. Ensure you have a Focalyst Pro account.
2. Open Focalyst on your phone or computer and go to the AI connections section, which you can find by following our guide on How do I connect Focalyst to Claude, ChatGPT or Gemini?. The setup process is straightforward and walks you through authorizing the connection.
3. Select Claude and follow the instructions to link your account securely.
4. Once linked, the AI app will gain read access to your tasks, habits, focus time, countdowns, and notes. This comprehensive access allows it to provide more relevant and personalized advice.
5. You can also instruct it to add new tasks, add a habit, log habits, or add countdowns directly within Focalyst. For instance, you could tell it to "add a task to review chapter 3 by Friday" or "log my 'reading' habit for today." This two-way interaction makes it a dynamic assistant for your planning.
6. Remember that the specific Claude models you can use depend on your active plan with Anthropic. Make sure your Anthropic subscription supports the models you intend to use.

Prompts to try with your Focalyst data

Once connected, you can start using Claude with your Focalyst data right away. Here are some specific prompts to help you get started and apply AI Leverage to your daily planning and study. These actions can be done tonight or this week.

• Task Prioritization: "Review my current tasks and suggest the top 3 high-priority items for tomorrow, considering my deadlines and existing tags. Explain your reasoning." This uses your existing tasks to help you plan your day more effectively.
• Habit Analysis: "Analyze my habit data for 'daily meditation' over the last month. Identify any patterns in missed days or successful streaks. Suggest one small adjustment to help me stay consistent." This prompt helps you improve your habits by using your Focalyst habit tracking. If you want to add a new habit, you can learn more on How do I add a habit in Focalyst?.
• Focus Session Planning: "I have a 3-hour study block for my upcoming exam. Based on my study tasks and notes, what's the most effective way to break this into Pomodoro sessions? Include specific topics for each focus block." This helps structure your focused work time.
• Countdown Milestones: "I have an exam countdown for [date]. Based on my current notes and tasks related to this exam, outline key study milestones I should aim to hit each week until the exam." Use this to break down large goals linked to your countdowns.
• Voice Note Expansion: "Expand on the summary of my latest voice note about [topic]. Generate potential follow-up questions or research directions based on the content." This extends your thinking from your recorded voice notes.

Limits to know

While AI Leverage offers powerful capabilities, you need to understand the practical limits and requirements for using Claude with Focalyst. This ensures you can plan effectively and avoid unexpected issues with the integration.

Connecting AI models like Claude to Focalyst requires a Focalyst Pro account. Your access to specific Claude models, like Opus 5.5 or Haiku 5.5, depends on your active plan with Anthropic. Focalyst's AI connections use a credit system: Pro users get 500 credits a month, plus 10 for each day they open Focalyst. These credits cover the processing power for AI interactions, so monitoring your usage can be helpful. The connection works through the AI app itself; it is not built directly into the model, meaning you interact with Claude via its own interface, which then accesses your Focalyst data. Remember that Gemini custom connections are only available on some Google accounts, so check your specific provider's terms if you are considering other AI models.
