LuisAI

Edit · View history

LuisAI is a real, forced-login chat product backed by a single underlying language model, presented to users as four distinct personas that differ only in their system prompt and per-model rate limits, not the model itself.

Personas

• LuisAI Pro -- thorough and precise, willing to go deep on technical detail and edge cases
• LuisAI Lite -- friendly and concise, favoring plain explanations over deep technical detail
• LuisAI Instant -- answers in one or two sentences with no preamble
• LuisAI Code -- a coding and systems specialist that defaults to code blocks over prose

Each persona has its own request rate limit and a per-message quota cost, with longer messages costing progressively more quota up to a capped multiplier so a single huge paste cannot exhaust an entire day's allowance.

Features

• Forced accounts -- there is no anonymous usage; every session requires signing up or logging in
• Tiered daily quotas -- Free and Pro tiers get different daily message allowances and session storage limits, with Pro also multiplying every model's rate limit
• Real-time streaming replies -- responses stream to the client as they're generated rather than arriving all at once
• Session history -- conversations are saved per account and can be resumed, listed, or deleted
• Image generation -- client-side image generation is available directly in chat via a third-party in-browser generation API, without routing image requests through LuisAI's own backend

Architecture

Like LuisSearch, LuisCloud, and LuisForge, LuisAI runs as a Python stdlib backend with SQLite for accounts and sessions, fronted by a Cloudflare-hosted static frontend that proxies API traffic to the real backend running behind a cloudflared tunnel.
