Make LLMs usable for everyone — swap terminal for a simple web chat UI

Many organizations and non-technical users struggle to access and benefit from large language models because the dominant interfaces are developer‑centric CLIs and SDKs that require coding, infrastructure and model‑management expertise. This creates friction for product teams, support agents and knowledge workers who could be part of the 200M potential annual AI‑chat users but prefer simple web or mobile chat experiences. You could build a lightweight web chat UI that swaps the terminal for a conversational front end with one‑click model selection, multi‑model routing, templates for common tasks, single‑sign‑on and embeddable widgets for product teams. The product would lean on efficient, smaller/optimized models (including “flash” variants) for low latency and cost, while offering paid access to higher‑quality models via routing and usage‑based billing. The market looks attractive now because efficient LLMs materially reduce compute cost and latency, expanding a reachable user base and making a low‑cost consumer product viable; the addressable market is roughly $12.0B (200M users × $60 ARPU/year) and the opportunity has a Market Score of 88/100 with Revenue Potential rated 90/100. UI democratization and rising demand for model plurality mean there is growing willingness among non‑technical users to adopt chat UIs that aggregate multiple models. To stand out you will need a strong model‑routing engine, clear curation and quality controls, enterprise controls for privacy/compliance, and an exceptional onboarding UX that proves <$60 ARPU through retention rather than one‑time trials. The challenges are real: competition is medium, integrations and staying current with new model releases are ongoing costs, and monetization requires reaching scale and convincing users to pay; but with tight latency and cost management, plus a focused go‑to‑market for vertical adopters, this idea can be commercially compelling.
