Make room for learning.

A plan that fits you

Choose beginner, intermediate or advanced, a plan length from 7 to 90 days or let AI decide, and your daily time commitment.

Keep everything with the lesson

Learn. Make a note.
Keep going.

Save an article, write down a question, or ask AI for resources on the day’s topic. Your notes and links stay beside the lesson they belong to.

  • See your progress. Mark days complete and follow your study streak.
  • Change the plan. Edit, add, reorder or regenerate days as your needs change.
  • Make it yours. Choose Light, Dark or match your system.

Your choice of AI

On your device. On your terms.

Start with Apple Intelligence, or connect your own OpenAI account. You choose how your study content is generated.

Apple Intelligence

Generate plans and lessons on-device, without an OpenAI account. Requires a compatible device with Apple Intelligence enabled.

Your own OpenAI key

Pick a model available to your account. Study topics and day descriptions go directly to OpenAI; your notes are not sent. Your key is kept in the system Keychain. Internet access and separate API charges apply.

Plans, lessons, notes and resources are stored locally. No account to create in Study Mood, no ads. Version 1.1 does not sync content between devices.

A little more room to think

At home on iPad and Mac.

A native three-column layout keeps plans, study days and resources in view. Pick the device where you like to learn; each device keeps its own library.

Frequently asked questions

What is free, and what does Pro include?

You can create study plans for free. The free allowance includes five lesson generations and five resource searches. Study Mood Pro unlocks unlimited lessons and resource suggestions with a monthly or yearly subscription. These limits apply with either AI provider; OpenAI API usage is billed separately to your own OpenAI account.

Do I need an OpenAI account?

No, if your device supports Apple Intelligence and it is enabled. Study Mood uses on-device Apple Intelligence by default. On a device without it, or if you prefer OpenAI models, add your own OpenAI API key in Settings. OpenAI usage requires an internet connection and may incur separate API charges.

Which devices are supported?

Study Mood is available for iPhone and iPad running iOS or iPadOS 26.0 or later, and Mac running macOS 26.0 or later. On-device generation requires a compatible device with Apple Intelligence enabled. Otherwise, use your own OpenAI API key.

Can I change a generated plan?

Yes. Rename the plan, change its start date, edit, add or reorder days, and regenerate an individual day. Choose Light, Dark or system appearance in Settings.

Does Study Mood sync between devices?

No. In version 1.1.0, plans, lessons, notes and resources are stored locally on the device that created them. Study Mood currently does not provide iCloud sync.

What is sent to OpenAI?

When you enable OpenAI, the app sends your study topic, the relevant day’s title and description, and instructions for generating the content directly to OpenAI. Your notes are not sent. Your API key is stored in the system Keychain and used to authenticate requests to OpenAI; it is never sent to Nestor Studio’s servers.

Does it work offline?

Saved plans, lessons and notes are available offline. Apple Intelligence generation runs on-device. OpenAI generation and opening online learning resources require an internet connection. AI-generated content can contain mistakes, so check important facts against trusted sources.

How do daily reminders work?

Choose a reminder time and allow notifications. Study Mood schedules reminders locally on your device. Today shows the current study days across your plans, plus a Catch up section for days you have missed.
