Frequently Asked Questions
Everything you need to know about Shift
Getting Started
What is Shift?
Shift is a powerful text enhancement tool that allows you to quickly modify and generate text using AI models. With Shift, you can transform your writing, generate code, and get instant AI assistance across any application
on your Mac.
How do I get started with Shift?
- Download and install Shift on your Mac
- Sign up for an account using your email or Google account
- Subscribe to start using the service
- Grant accessibility permissions when prompted
- Begin using Shift by double-pressing the right shift key
What are the system requirements?
Shift is currently compatible with macOS and requires an active internet connection for AI functionality. A Windows version is coming soon, allowing you to use Shift across both operating systems.
What is a token?
A token is a unit of text that AI models use to process and generate language. Tokens can be words, subwords, or even individual characters, depending on the context. For example, the phrase "AI is amazing!" consists of
four tokens: "AI", "is", "amaz", and "ing!".
Approximately 1 million tokens equate to around 750,000 words, though this varies based on text complexity and formatting.
How much does Shift cost?
Shift uses a transparent pricing model with two components:
- Base subscription: $6.99 per month
- Usage fees: Additional charges based on your actual token usage
Different AI models have different token costs, with more powerful models typically costing more. However, most users don't exceed $5 in monthly usage charges, even with heavy use. You can always monitor your usage and associated
costs in the app's Usage tab, and set spending limits to control your budget.
Can I use my own API keys?
Yes! Shift allows you to use your own API keys for these supported AI services:
- OpenAI (for GPT models)
- Anthropic (for Claude models)
- Google (for Gemini)
Your API keys are securely stored in macOS Keychain and are never transmitted to Shift's servers, ensuring maximum security.
Features & Usage
How does Shift work?

- Gemini (Flash variant)
- GPT (GPT-4o and GPT-4o Mini variants)
- Claude (Sonnet and Haiku variants)
- Llama 3.3 70B Versatile
- DeepSeek R1 Distill Llama 70B
Can I use multiple AI models?
Yes, you can easily switch between different AI models and their variants using the model selector in the interface.
What are Contexts?
Contexts are additional pieces of information you can add to your prompts by double-pressing left Shift. These contexts persist across multiple prompts and help the AI better understand your requirements.
What is Chat Mode?
Chat Mode allows you to have a continuous conversation with the AI. Features include:
- Enable it by clicking the chat icon

Security & Privacy
What are the key points of our Privacy Policy?
Our Privacy Policy is designed with your security in mind. We collect only the essential personal information needed for account registration (such as your name and email). For handling payment information, we rely on Stripe’s secure processing services.
Most of your data — including text, code, and other content — is processed and stored locally on your device. Only minimal data (for example, your API prompts) is transmitted to our Google Firebase servers to be processed
by trusted third-party AI providers. For further details, please read our full Privacy Policy.
Is the source code checked and certified by Apple?
Yes, the app source code is notarized and checked by Apple. As part of Apple’s rigorous security process for macOS applications, our app undergoes a notarization process. During notarization, the app is automatically scanned
by Apple’s security tools to detect any malicious content or vulnerabilities. Once the scan is successful, Apple issues a notarization ticket, which is attached to the app. This ticket verifies that the app meets Apple’s
strict security standards, ensuring its integrity and that it hasn’t been tampered with. This process gives users an added layer of confidence in the app’s security.
How is my data stored and secured?
We place a high priority on your security by keeping most of your data stored locally on your device. Very little data is sent to our cloud servers — and that only for processing API requests. This approach minimizes the risks associated with cloud storage
while ensuring that your sensitive information remains private.
What is that macOS password prompt I occasionally see?
This is Apple's keychain security system at work, not our app directly asking for your password. When you first use certain features of our app, macOS displays this prompt as a security feature to help protect your sensitive
information. The keychain securely stores data locally on your device, not in the cloud.
Is it okay to enter my password when prompted?
Yes, it's completely safe. The password prompt comes directly from macOS, not our app. Your password is never seen, stored, or transmitted by our application. Apple's system uses your password to unlock secure storage for
app-related credentials.
What if I prefer not to enter my password?
If you choose not to enter your password, some features of the app may not work properly. The app will still function, but certain personalized settings or secure features might be limited.
How does the app use Apple's keychain?
We use Apple's secure keychain to safely store data locally on your Mac:
- Your personalization preferences
- Authentication tokens
- API credentials
This ensures that your data remains encrypted and protected on your local device, not in the cloud, rather than storing it in a less secure way.
Will I see the password prompt every time I use the app?
No. In most cases, you'll only be asked once per session or after significant system events like restarts. macOS remembers your choice to allow keychain access.
Can the app access my other passwords stored in keychain?
Absolutely not. Our app can only access its own designated area in your keychain, not any other passwords or credentials you have stored for other applications or websites.
Are the keychain prompts normal for macOS apps?
Yes, these prompts are a standard Apple security feature present in many professional macOS applications. They're actually a sign that the app is following Apple's security best practices by storing sensitive data securely
on your device.
What specific information does Shift store in the keychain?
We only store the following data locally in your Mac's keychain:
- Authentication tokens and credentials
- App-specific API keys
- User session information
This information is stored locally on your device, not in the cloud. We do not store your Apple ID password, credit card information, or any other sensitive personal data in the keychain.
Subscription & Pricing
How does the pricing work?
Our pricing model is simple and transparent:
- Fixed base subscription of $6.99 per month
- Additional usage-based billing for the tokens you consume
- Most heavy users typically don't exceed the $5 base fee in usage charges
- You're only charged for what you actually use
- Different AI models have different token rates
How do I track my usage?
The Usage tab in the settings provides detailed information about:
- Total tokens used
- Cost breakdown by model
- Input and output token counts
- Visual analytics of your usage
Troubleshooting
Why isn't Shift responding?
Common solutions:
- Check your internet connection
- Verify your subscription is active
- Ensure accessibility permissions are granted
- Restart the application
How do I update Shift?
Shift regularly releases updates with new features, security improvements, and bug fixes. You can update in two ways:
