What is Blue?
Blue is a macOS‑native AI assistant that lets you use ChatGPT‑like models directly inside any Mac app, without copying text into a browser. It appears with a keyboard shortcut (Option + Space) and analyzes whatever is on your screen, so you can summarize, translate, rewrite, or analyze content in context, whether you are coding, writing reports, or browsing documents.
Key features include AppVision, which understands the visual layout and content of the window you are working in, and automatic model selection between GPT‑4 and GPT‑3.5 Turbo for a balance of speed and reasoning. Blue is tightly integrated with macOS accessibility layers, so it can read and act on text from third‑party apps, spreadsheets, PDFs, messaging windows, and more.
Blue targets professional and privacy‑conscious users who want AI help inside their existing workflows without leaving sensitive data in cloud‑only chat assistants. It is positioned for developers, writers, analysts, and office workers who value staying in their apps while having a powerful AI sidekick that respects GDPR and keeps data on‑device.
Blue pricing
Pricing model: Freemium
Blue offers a free trial with no credit card required, letting users test the app before committing. The paid plans include a Bring Your API plan at 5 USD per month, which lets you use Blue as a client for your own OpenAI API key, a Starter plan at 10 USD per month aimed at individual professionals who use AI regularly, and a Pro plan at 20 USD per month for power users who rely on AI daily. The Starter and Pro tiers include a monthly quota of around 250K tokens, which typically covers 10–15 daily messages; if the GPT‑4 quota is exhausted, Blue falls back to GPT‑3.5 only while still working normally.

Frequently asked questions about Blue
What is Blue and how does it work?
Blue is a macOS‑native AI assistant that lets you use ChatGPT‑style models directly inside any Mac app by pressing Option + Space. It uses AppVision to see whatever is on your screen, so you can ask it to summarize, translate, rewrite, or analyze content without leaving the app or copying text manually.
Which AI models can I use with Blue?
Blue gives access to models such as GPT‑4 and GPT‑3.5 Turbo, automatically switching between them to balance reasoning quality and speed. The app selects the appropriate model based on your query and the amount of context you select on screen.
Is my data stored in the cloud or on my Mac?
Blue keeps your messages, files, and other data stored on your Mac, encrypted with AES‑256 using your Apple ID. It only sends data from the currently active app when you ask a question and does not store a copy of that data after it is processed.
How does Blue protect my privacy?
Blue is GDPR‑compliant, does not use your data to train underlying AI models, and avoids third‑party tracking scripts. All message data and PII are stored on your device, traffic is encrypted with TLS 1.2+, and for EU users data processing stays within the European Union.
Can I use my own OpenAI API key with Blue?
Yes, Blue offers a Bring Your API plan at 5 USD per month, which lets you connect Blue to your own OpenAI API key and use it as a client for your existing quota instead of Blue’s bundled models.
What does AppVision do exactly?
AppVision is Blue’s technology that reads and understands the content and layout of the window you are working in. It captures not only text but also spatial information such as alignment and visual cues, allowing Blue to give more accurate and context‑aware answers without you having to describe the screen.
Which versions of macOS does Blue support?
Blue is designed for macOS 12.6 Monterey and later versions. It leverages native macOS accessibility frameworks, so older macOS releases are not supported.
Is Blue available for Windows or other platforms?
Blue is currently only available for macOS. A Windows version is in development but not yet released, so Windows and Linux users cannot use Blue at this time.
How are Blue’s monthly tokens and GPT‑4 quota structured?
The Starter and Pro plans provide a monthly quota of roughly 250K tokens, which is usually enough for around 10–15 daily messages depending on length. If your GPT‑4 quota is exhausted, Blue continues to work using GPT‑3.5 Turbo only instead of blocking your usage.
Is there a free trial and how long does it last?
Yes, Blue includes a free trial that does not require a credit card. The trial lets you test all core features and AI models before choosing a paid plan, though the exact trial duration is set by the current campaign and may vary over time.
