Show HN: PLAI.chat – Multi-model AI chat that doesn't store your conversations (opens in new tab)

I built PLAI.chat because I was frustrated with two things: 1) new models ship every week and I was constantly switching between apps to keep up. 2) Every service stores my conversations on their servers.

So, PLAI.chat takes a different approach: your chat history is stored only in your browser's localStorage — never on our servers. API calls go to model providers via OpenRouter, but we don't log, store, or train on any conversations — and they aren't linked to any user identity on our end. We don't store anything. The architecture makes the privacy guarantee verifiable, not just a policy claim.

You can try it right now, no account needed. Go to plai.chat and start chatting for free. For more models or higher limits, sign in with a magic link — no forced registration, no confirmation hoops.

What it does: - 300+ models (GPT, Claude, Gemini, Llama, Mistral, Qwen, and more via OpenRouter) - Free to start, pay-per-use for extended usage — no subscription - Chat history in your browser only — close the tab, it's still there; we never see it - Switch models mid-conversation to compare responses; presets for free/balanced/premium - Supports files, PDFs, images, and image generation

I also built a Slack version — but still waiting on Slack's marketplace approval, which has been... slow.

Stack: Next.js, Cloudflare Workers, Stripe, OpenRouter.

Thanks for your feedback and comments!
