FAQ

BYOK (Bring Your Own Key) means you use your own API key to connect to AI services. Unlike hosted solutions, your data goes directly from your browser to your chosen AI provider (like DeepSeek, OpenAI) without any intermediate server. No third party can access your conversations, and you have full control over your data.

6 built-in presets + custom option: 1) DeepSeek (default, fast in China); 2) MiMo (Xiaomi open-source model); 3) OpenAI (GPT-5.6 sol / terra / luna); 4) Anthropic (Claude Sonnet 5 / Opus 5 / Haiku 4.5); 5) OpenRouter (one API for multiple platforms); 6) Custom (any OpenAI-compatible API). Just select a preset and enter your API key.

Absolutely not. API keys are stored in chrome.storage.local and only sent via HTTPS directly to your configured AI provider when you make a request. Keys are never logged, shared, or sent anywhere else. Deepdeep has no servers and no account system.

Three core differences: 1) BYOK mode — you bring your own API key, no middleman, direct connection to AI providers; 2) Zero data collection — no analytics, no telemetry, no accounts, no tracking; 3) Minimal design — text selection popup + sidebar chat + @tab references, covering all scenarios without bloat.

Three steps: 1) Install Deepdeep extension; 2) Select "DeepSeek" preset in settings, Base URL is auto-filled; 3) Create an API key at platform.deepseek.com/api_keys and paste it into settings. Default model is deepseek-chat.

Select any text on any webpage and a small toolbar pops up automatically. Click "Ask AI" to ask directly, or choose "Explain", "Translate", "Summarize" for quick actions. After AI replies, you can continue asking follow-up questions in the popup. Uses Shadow DOM isolation to avoid affecting the original page.

Open Deepdeep sidebar (Ctrl+Shift+D), type @ in the input box, and a list of currently open tabs appears. Select the tab you want to reference, and Deepdeep automatically extracts its content (up to 8000 chars) as context. Reference multiple tabs for cross-page comparison and analysis.

No. Deepdeep has no servers, no account system, no analytics, and no telemetry. Your API settings and active chats are stored locally in the browser. Conversation content is only transmitted between your browser and your chosen AI provider. See our privacy policy.

Built on Chrome Manifest V3, supporting all Chromium-based browsers including Chrome (114+), Edge, Brave, Arc, etc. Sidebar functionality relies on the Side Panel API, natively supported in Chrome 114+.

The extension itself is completely free. You pay your AI provider based on their pricing. Some providers (like DeepSeek, MiMo) offer free tiers.
