What is a21e?
a21e turns natural-language instructions into expert AI outputs. Instead of writing prompts, you describe what you want — a21e selects the best techniques, compiles an optimized prompt, routes it to the right model, and returns production-quality results.- Parses your intent — understands what you’re asking for, the constraints, and the success criteria
- Selects techniques — matches your intent to curated prompt strategies from the prompt library
- Compiles a prompt — assembles a structured prompt with your context, preferences, and memory
- Routes to the best model — picks the optimal LLM for the task (or deliberates across multiple models)
- Returns results — delivers the output with quality scoring and feedback capture
Key capabilities
Intent execution
Submit natural-language intents via API or the Huddle interface. a21e handles prompt engineering automatically.
Multi-model deliberation
For complex decisions, a21e runs multiple models in parallel — each plans, critiques the others, and a consensus emerges.
Persistent memory
a21e remembers your preferences, corrections, and context across sessions. Every interaction makes future results better.
OpenAI-compatible API
Drop-in replacement for the OpenAI chat completions endpoint. Switch one line and get enhanced results.
How it works
1
Get an API key
Sign up at a21e.com and generate an API key from the dashboard.
2
Submit an intent
Send a natural-language instruction to the API. a21e handles the rest.
3
Get results
a21e returns the executed output along with quality metadata, credits used, and the model selected.
Pricing
a21e uses a credit-based model. 1 credit = 1 enhancement (one prompt compilation and execution).- Managed mode — a21e handles LLM calls. Credits cover both prompt engineering and model inference.
- BYOK mode — Bring your own API keys for Anthropic, OpenAI, Google, or xAI. Credits only cover prompt engineering.
