Pay for the platform. Pay only for what you use with AI.
API costs for AI usage are billed separately based on actual usage. You provide your own API keys for complete transparency and control.
Large Language Models are advanced AI systems trained on vast amounts of text to understand and generate human-like language. They power modern AI assistants and can draft documents, analyze text, and respond to complex questions.
Several companies provide LLM services:
Claude models consistently outperform competitors in legal reasoning, nuanced analysis, and following complex instructions. Claude is also designed with strong safety guardrails, reducing hallucinations and improving reliability for professional use.
Services like ChatGPT Plus or Claude Pro are consumer subscriptions ($20/month) designed for casual use. They include:
API access is how professional applications like AutoDrafter connect to AI models. Benefits include:
Tokens are the units AI models use to process text. One token is roughly 4 characters or 0.75 words. A 1,000-word document is approximately 1,300 tokens.
| Model | Input | Output |
|---|---|---|
| Claude Sonnet 4.5 (Balanced) | $3 / million tokens | $15 / million tokens |
| Claude Opus 4.5 (Most Capable) | $15 / million tokens | $75 / million tokens |
Costs vary based on document complexity, context needed, and model selected. Here are representative examples using Claude Sonnet 4.5:
| Document Type | Typical Context | Est. Cost |
|---|---|---|
| Simple correspondence | Minimal | $0.02-$0.05 |
| Discovery requests | Moderate | $0.10-$0.25 |
| Motion to compel | High | $0.15-$0.50 |
| Summary judgment brief | Very high | $0.50-$2.00 |
| Complex appellate brief | Maximum | $1.00-$5.00 |
For complex work requiring Opus 4.5 (the most capable model), multiply by approximately 5x. Even then, costs remain a fraction of the time saved.
Platforms that charge a flat monthly fee must limit your usage to stay profitable. They do this by:
With AutoDrafter, you're not locked into any single AI provider. Your knowledge base, matter memory, document styles, and all customizations are stored independently of the AI models.
Unlike general AI chatbots where customizations vanish when you switch providers:
General AI assistants are powerful but lack critical capabilities for legal work:
Every piece of knowledge you add, every matter you configure, every document you draft makes the system more valuable. This accumulated intelligence is yours permanently.
General LLMs can't provide forced knowledge injection, persistent memory, or court-ready formatting. AutoDrafter fills the gap between raw AI capability and professional legal requirements.
AI API costs drop 20-40% annually while capabilities improve. With BYOK, you benefit immediately from every price reduction. Flat-fee platforms pocket the savings.
With general AI chats, switching models means losing everything. With AutoDrafter, your knowledge base, memory, and styles transfer instantly to any new model.
