Everything you need to know about 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.
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.
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.
Shift uses a transparent pricing model with two components:
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.
Yes! Shift allows you to use your own API keys for these supported AI services:
Your API keys are securely stored in macOS Keychain and are never transmitted to Shift's servers, ensuring maximum security.
Shift supports multiple AI models:
Yes, you can easily switch between different AI models and their variants using the model selector in the interface.
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.
Chat Mode allows you to have a continuous conversation with the AI. Features include:
Yes, you can add custom system instructions that will be included with every prompt. This helps guide the AI's responses to better match your needs.
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.
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.
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.
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.
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.
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.
We use Apple's secure keychain to safely store data locally on your Mac:
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.
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.
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.
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.
We only store the following data locally in your Mac's keychain:
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.
Our pricing model is simple and transparent:
