Dorin.ai is an AI-powered browser assistant available as extensions for Chrome, Edge, and Firefox, as well as a Web App. It brings chat, webpage summarization, AI search, writing, translation, email replies, PDF/image Q&A, image generation, and more into the browser sidebar and input fields. Its main positioning is to improve efficiency in everyday browsing, office email, and social media interactions.
According to the product copy, Dorin integrates text models such as ChatGPT/GPT, Claude, Gemini, and DeepSeek, and lists GPT-5, GPT-4o, Claude 4 Sonnet/Opus, Gemini 2.5, DeepSeek V3, and others. On the image side, it also mentions Stable Diffusion, Flux, DALL-E, Midjourney, and more. In terms of features, Read can summarize webpages, images, PDFs, and screenshots; Search can provide answers based on multiple sources; Write supports custom formats, tones, lengths, and languages; and Translate supports 50+ languages while preserving webpage layout.
Dorin gives fairly detailed descriptions of its Gmail and Outlook features: it can generate structured emails, context-aware replies, adjust tones such as formal/casual/professional, automatically fill in key information like names and dates, and summarize long emails. It also integrates with LinkedIn, Twitter, Facebook, Instagram, and YouTube for generating comments, replies, and video summaries. The BYOK plan supports connecting API keys from OpenRouter, ChatGPT, Gemini, Claude, Stable Diffusion, DeepSeek, Flux, and others, making it suitable for users who already have model usage quotas.
The product offers a 3-day free trial. The Student plan is $12.5/month, or $15 when billed monthly, and includes 10 content generations per day, simple web research, and advanced models. Pro is $30/month, or $40 when billed monthly, and offers unlimited content generation, deep web research, and Premium models. BYOK is $99/year, uses your own API keys, and includes team collaboration, centralized billing, custom templates, a dedicated customer manager, and more. Payment methods are not disclosed in the main copy.
Its strengths are that it covers high-frequency workflows and, once the extension is installed, can be invoked directly within webpages, email, social media, and documents, with a low learning curve. Multi-model support and BYOK also improve flexibility. The downside is insufficient disclosure around data privacy: it does not explain how email, webpage, or PDF content is stored, whether it is used for training, or whether it is transferred to third parties. Some features, such as meeting scheduling, phishing detection, and attachment insights, also lack implementation details. It is suitable for students, researchers, marketers, developers, analysts, and knowledge workers who frequently handle emails or web content.
The main copy does not provide information on access from mainland China, network stability, or payment methods, so china_access can only be rated as unknown. Given its reliance on overseas models such as ChatGPT, Claude, and Gemini, real-world usability may be affected by network conditions and model API availability. Comparable browser AI assistants include Monica, Sider, Merlin, MaxAI.me, and Microsoft Copilot.
