Remio is well-designed and great for users who want a polished out-of-box research tool. If you want full control over your knowledge base — where it's stored, what AI processes it, how the workflow works — PlugThis lets you build a custom research assistant.
Remio is a Chrome extension and web app that helps users save webpages, organize research, and chat with their saved knowledge using AI. It positions itself as a "second brain" for knowledge workers and researchers.
Pricing: Remio offers a free tier with limited usage, with paid plans for unlimited saves and advanced AI features. Pricing varies; check their site for current rates.
Audience: Researchers, knowledge workers, students, and PKM (personal knowledge management) enthusiasts.

What you get:
Build a Chrome extension called "Knowledge Assistant" for research and knowledge management. The extension should: (1) provide a "Save this page" button in the popup that captures the current page (URL, title, full article content via readability extraction, AI-generated summary), (2) save to a Supabase backend with embeddings generated via OpenAI for semantic search, (3) provide a chat interface in the popup where the user can ask questions answered using their saved knowledge as context (RAG: retrieve top 5 relevant saved pages by embedding similarity, send to GPT-4 with the question), (4) provide a search interface for browsing saved pages by keyword or semantic search, (5) provide an options page for OpenAI API key entry. Permissions: storage, activeTab. Host permissions: <all_urls>, https://api.openai.com/*. Manifest V3 with Supabase backend.
Free tier limited; paid tiers vary

It uses RAG (retrieval-augmented generation): when you ask a question, the extension finds the most relevant saved pages using semantic search (embedding similarity), then sends those pages plus your question to GPT-4 to generate a grounded answer.

No. Your knowledge lives in your own Supabase project, not on PlugThis's servers. The extension is your source code. Even if PlugThis disappears, your data and tools remain.

Possibly — depends on what export Remio offers. If they export to JSON/Markdown, you can write a small import script (PlugThis can build that too).
