Frequently Asked Questions
Everything you need to know about SPRAPP.
What is SPRAPP?
SPRAPP is a browser-based platform that lets you chat with multiple AI models (Claude, GPT, Grok, Gemini, and 300+ others) from a single interface. In Council mode, multiple models debate your question through a three-phase deliberation process — fan-out, peer review, and synthesis — to deliver a cross-checked consensus answer.
Is it really free?
Yes. The free tier gives you access to free models from OpenRouter and Google Gemini with no credit card required. You can also bring your own API keys (BYOK) to use any model on the free plan. The optional Lite subscription ($3-9/month) adds premium features.
Do you store my conversations?
No. All conversations are stored locally in your browser's IndexedDB. There is no backend server processing or storing your chats. Your messages go directly from your browser to each AI provider's API. We never see, intercept, or store your conversations.
What is BYOK (Bring Your Own Key)?
BYOK means you use your own API keys from providers like Anthropic, OpenAI, xAI, Google, or OpenRouter. Your keys are stored in your browser's localStorage and sent directly to the provider — we never see or store them. You pay each provider directly at their rates.
How does Council mode work?
Council mode runs a three-phase deliberation: (1) Fan-out — your question is sent to multiple models in parallel; (2) Peer review — each model reviews the other models' answers; (3) Synthesis — a chairman model produces a final consensus answer noting where models agreed and diverged.
What AI models are supported?
Claude (Anthropic), GPT and o-series (OpenAI), Grok (xAI), Gemini (Google), 300+ models via OpenRouter, and any model you run locally with Ollama. The registry is open source — contribute models and providers at github.com/sprapp/registry.
How is my data protected?
SPRAPP uses a zero-server architecture. There is no backend server, no database, and no application server to breach. Your data stays in your browser. API keys never leave your device except to go directly to the AI provider. All connections use HTTPS/TLS encryption.
Can I use local AI models?
Yes. SPRAPP supports Ollama for running local LLMs on your own hardware. No API key is required. Ollama models are auto-detected when running locally, and you can configure a custom endpoint in Settings.
How does geo-tiered pricing work?
The Lite subscription price ranges from $3 to $9 per month (USD equivalent) based on your country's cost of living. Your pricing tier is determined automatically via Cloudflare's country detection. Payments are processed by Stripe and PayPal.
