AI agents don't fail because the AI isn't smart enough. They fail because nobody defined the job. AI Agent Builder Architect turns your rough idea into the precise, structured instructions a real AI agent needs: its mission, its tools, its skills, its boundaries, its voice. Describe the job once. Get an agent blueprint in minutes. Copy, deploy, delegate. WHY THIS EXISTS You've seen it happen. You ask for an agent that "handles my leads" and get something that technically responds but actually does nothing well. The problem isn't the model - it's that nobody told it what the job really is. AI Agent Builder Architect is the architecture layer that comes BEFORE the agent builder. It interviews you like a systems designer would: what's the job, which tools does it need, what should it sound like, where are the edge cases. Then it writes the agent specification you'd never have written yourself. HOW IT WORKS 1. Pick the job - personal assistant, lead generator, support triage, research, content, and more. 2. Pick its tools - 50+ integrations to choose from. 3. Describe what it should do in plain language. No jargon required. 4. Give it a voice - ten distinct tones, each with a live preview of how your agent will actually sound. 5. Review its skills - small, focused abilities the AI suggests, chained into a complete workflow. Keep, edit, or regenerate. 6. Answer a few quick clarifying questions about the details that make or break an agent. 7. The architect does the rest - a polished, complete, deployment-grade agent blueprint, ready to paste into your AI agent builder. WORKS WHERE YOU BUILD The blueprint is yours. Paste it into your favorite AI agent builder, and the app will point you to a recommended one to deploy in minutes. KEEP BUILDING, NOT JUST STARTING After the first blueprint, this becomes your agent workspace. Every agent you design is saved with its own AI chat, where each reply is another ready-to-use refinement - new skills, tighter instructions, sharper behavior. Build one agent or a whole team of them. WHO IT'S FOR 1. Founders delegating their busywork to agents instead of hiring for it 2. Marketers who want a lead-qualifying agent running by Friday 3. Support teams triaging tickets automatically 4. Freelancers and consultants shipping agents for clients 5. Anyone who's tried building an AI agent and got a chatbot instead THE PROMISE Describe the job once. Get an agent that actually understands it. There's already an AI agent that could take real work off your plate. AI Agent Builder Architect is how it finally gets built - properly.

About

LLMAPI

Read full description

Every free LLM. One app. LLMAPI is a chat client and an API router. It knows which models the big providers give away, how much quota each one has left, and which one is smartest for what you just asked — and it picks for you, on the device, in the moment. AUTO-ROUTING THAT ACTUALLY ROUTES Ask a question. LLMAPI scores every model you can reach right now — by capability, by remaining quota, by how fast it has been answering — and sends your prompt to the best one. If that provider is rate-limited, it fails over to the next one mid-request. Every answer shows what served it: provider, model, latency, and how many failovers it took. Nothing is hidden behind a spinner. Prefer to drive? Priority mode lets you drag the model chain into your own order, or pull models out of routing entirely. WORKS WITH ZERO SETUP No account. No sign-up. No credit card. Four providers serve anonymous free tiers, so the app answers your first message seconds after you open it, before you configure anything. BRING YOUR OWN FREE KEYS Every provider in the list has a genuinely free tier: Google AI Studio, Groq, Cerebras, NVIDIA NIM, Mistral, OpenRouter, Cloudflare Workers AI, Cohere, Ollama Cloud, HuggingFace, GitHub Models and more. Paste a key and LLMAPI validates it live before saving, watches its health, and round-robins across multiple keys for one provider. Keys are stored in the iOS Keychain. They go to that provider and nowhere else — not to us, not through any server of ours. You can also point it at your own local or hosted endpoint — llama.cpp, LM Studio, vLLM, any /v1 base URL. YOUR PHONE AS AN API SERVER (PREMIUM) Turn on the LAN server and your iPhone serves a standard chat-completions API to everything else on your Wi-Fi. Point any chat-completions SDK, the Anthropic SDK, curl, or any agent framework at your phone's address; it auto-routes across every free tier you can reach, exactly like the chat tab. - POST /v1/chat/completions, streaming and non-streaming - POST /v1/messages, Anthropic-compatible - GET /v1/models - Bearer-key authenticated, generated on device - Scan the QR code for a connection page with copy-paste snippets It runs only while the app is open and switched on. A Low Power Screen dims the display to near-black so an OLED draws almost nothing while serving, and a battery guard stops the server at 10% unless you are plugged in. A CATALOG YOU CAN TRUST Hundreds of models across 28 providers, with real rate limits, context windows, tool and vision support. The catalog is fetched from our service and its Ed25519 signature is verified on your device before any model loads. A tampered catalog is rejected. PRIVACY, PLAINLY - Chat history lives in a database on this phone. It is never uploaded. - Provider keys live in the Keychain. They go to the provider, and nowhere else. - There is no analytics SDK in this app. None. - No account to create, so no profile to build. - Your prompts go to the AI provider that answers them, under that provider's terms. That is the only place they go. FREE VS PREMIUM Free, forever: auto-routing, failover, quota tracking, chat history, and the anonymous free-tier models. No trial, no countdown. Premium adds: every model in the catalog rather than the keyless few, the LAN API server, and the live catalog feed — new free models and quota changes reach you the day we ship them instead of thirty days later. Premium Annual is an auto-renewing subscription. Premium Lifetime is a single payment. A NOTE ON AI OUTPUT LLMAPI relays answers from third-party models, including open community models that apply little or no filtering. Output can be wrong, biased, or offensive, and it is not reviewed by us before you see it. Long-press any answer to report it. Do not rely on it for medical, legal, or financial decisions.
