Arvin

Arvin AI is a web app for individuals who want an AI copilot for reading, writing, translation, and quick design tasks while browsing.

Key capabilities include:

• Sidebar AI chat across sites using multiple models (including GPT-4o, Claude, and Gemini), plus a prompt library and slash-command style interactions
• Webpage and document summarization, including area-based summaries for articles, landing pages, and other on-page content
• Writing assistance for content creation and rewriting, including professional email drafting and replies (notably in Gmail)
• Translation for text and webpages (25+ languages)
• AI image and design tools, including one-click generators for logos, signatures, icons, business cards, plus background removal/change, image upscaling, and sketch-to-image conversion

Pricing: Free (daily credits available); paid plans exist, but specific tiers and amounts were not provided.

What makes it notable: it combines multi-model chat, in-page summaries/translation, and design plus image editing in a single browser extension experience, with quick access via hotkey and site integrations (Google, docs, LinkedIn, Twitter, Gmail).
