1. Step 1: Write your promptDescribe the topic, tone, format, and length you want the AI to produce.
2. Step 2: Submit for generationThe router tries configured cloud providers in order, falling back to the next available option on failure.
3. Step 3: Review and edit outputCopy the generated text, note which provider and model were used, and refine before publishing.
4. Step 4: Paste your textAdd your text into the main field. Long drafts are fine for typical article lengths.
5. Step 5: Run AI WriterSubmit the form so processing happens server-side in one pass.

The AI writer sends your prompt through a provider router that attempts OpenAI first, then Anthropic and Gemini (Google) as configured fallbacks. If no cloud API keys are available or all providers fail health checks, a local template provider generates structured placeholder copy so the tool remains usable. Requests are rate-limited to 60 per IP and 30 per tool per minute. Output defaults to 1,024 max tokens unless overridden.

Skip the hype—here is what actually helps when you open AI Writer.

• ✓Reliable multi-provider routing — Automatic failover across OpenAI, Anthropic, and Gemini reduces downtime when a single API is unavailable.
• ✓Works without API keys — The local template provider produces draft output when cloud keys are not configured, so you can test the workflow immediately.
• ✓Beat the blank page — A draft you can edit is faster than inventing structure from zero every time.
• ✓You keep editorial control — Nothing publishes itself—review facts, tone, and claims before anything goes live.
• ✓Try tone without rewriting by hand — Generate a second pass when formal copy needs a looser voice—or the reverse.
• ✓Unblock teammates waiting on words — Design and product can move with a first draft while you polish the final.
• ✓Fast enough for real deadlines — Most runs finish in seconds so the tool does not become the bottleneck.

Key features

• ✓Provider failover chain — Routes through OpenAI, Anthropic, and Gemini with automatic fallback and cooldown handling.
• ✓Local template fallback — Generates structured draft text via local-template-v1 when no cloud AI keys are present.
• ✓Transparent metadata — Returns provider ID, model name, fallback status, and token usage when available.
• ✓Rate-limited access — Protected by per-IP (60/min) and per-tool (30/min) limits to ensure fair usage.
