Rewind
Lumi solves the #1 frustration with AI: every new thread starts from zero. Whether you use one AI tool or many, Lumi keeps your context alive across sessions and threads. Start a new Claude chat and it already knows your project, your preferences, your history. No re-explaining. No copy-pasting old threads. The core philosophy is store wide, retrieve narrow: Upload documents, PDFs, and notes, Lumi chunks and indexes them automatically so your AI can retrieve exactly the right section when you need it, like a personal RAG without the setup. Save everything once, and Lumi surfaces only the memories relevant to your current prompt. This eliminates redundant context in every message, significantly reduces token usage on long projects without losing a single detail. Works across Claude, ChatGPT via MCP and Gemini CLI via a simple configuration file. Organize memories into vaults and collections. Setup takes 60 seconds via OAuth. Privacy-first: encrypted in transit and at rest, never sold, never used to train AI. Free tier includes 300 memories and 2 vaults.

Lumi AI's answer:
Lumi is the only persistent memory layer that works across Claude, ChatGPT, and Gemini CLI simultaneously. Unlike native memory that's locked to a single tool, Lumi's context travels with you everywhere. The core philosophy: store wide, retrieve narrow means everything is saved but only what's relevant surfaces per prompt, dramatically reducing token usage without losing continuity. Document and PDF upload with automatic RAG indexing means your AI can reference your actual files, not just your typed notes.
Lumi AI's answer:
Most AI memory tools either work with one platform or require complex setup. Lumi connects in 60 seconds via OAuth with no configuration files, works across the three most popular AI tools, and organizes memories in structured vaults and collections rather than a flat list. The semantic search understands meaning, not just keywords. Privacy is built in at the infrastructure level AES-256 encryption, row-level data isolation, and full user-controlled deletion. Free tier requires no credit card.
Lumi AI's answer:
Lumi is built for AI power users, developers, founders, researchers, consultants, and knowledge workers who use Claude, ChatGPT, or Gemini daily for serious work. Specifically people who work on long projects across multiple sessions and tools, and who are frustrated by losing context every time they start a new chat. Technical enough to appreciate MCP integration, but the product is designed so anyone can set it up in under a minute.
Lumi AI's answer:
Lumi was built out of personal frustration. Every AI session started from zero, re-explaining the same project context, the same preferences, the same background. The solution was a persistent memory layer that sits above all AI tools, stores context once, and makes it available everywhere. Lumi launched in April 2026 under Uedge, with a focus on simplicity, privacy, and genuine utility for daily AI workflows.
Lumi AI's answer:
Lumi is built on Next.js and TypeScript for the frontend and API layer, Supabase with PostgreSQL and pgvector for storage and semantic search, OpenAI embeddings for vector generation, OAuth 2.0 with PKCE and RFC 7591 dynamic client registration for secure MCP connections. The architecture follows Model Context Protocol standards for interoperability across AI platforms.
Lumi AI's answer:
Lumi launched in April 2026 and is in early growth stage. Current users include AI power users, developers, and productivity-focused professionals who use multiple AI tools daily. Customer case studies will be published as the user base grows.
