The Promise

Cheaper for you. Lighter on everything else.

Smart routing isn't only about your bill. It's about using the smallest model that can do the job — and being honest about which one ran.

  1. 01
    Sustainability
    Smallest capable model, always.

    Routing to the right-sized model means fewer GPU cycles, lower carbon, and watts that don't get burned on a one-line summary.

  2. 02
    Privacy & data ownership
    Never used to train foundation models.

    Prompts and responses are not contributed to OpenAI, Anthropic, or Google training sets. You own the conversation, and you can export or delete it at any time.

  3. 03
    Transparency
    Every receipt shows which model and why.

    See the model, the cost, and the savings on every reply. Read our transparency report and privacy policy.

The Math

How your savings are calculated.

No magic, no marketing math. Every receipt compares what we actually paid to route your prompt against what the same tokens would have cost on a frontier model.

Formula
routed_cost = (in_tokens × in_rate) + (out_tokens × out_rate)
baseline_cost = (in_tokens × opus_in) + (out_tokens × opus_out)
savings = baseline_cost − routed_cost
  1. 01
    Step 01
    We classify your prompt

    A lightweight classifier reads the task — drafting, summarizing, reasoning, code — before any frontier model is touched.

  2. 02
    Step 02
    We route to the cheapest capable model

    Each task has a shortlist of models that pass our quality bar. We pick the cheapest one — across OpenAI, Anthropic, Google, and open-source.

  3. 03
    Step 03
    We price the answer two ways

    Routed cost = (input + output tokens) × the routed model's published per-token rate. Baseline cost = the same tokens at GPT-5 / Claude Opus rates — what a naïve 'always-frontier' setup would have charged.

  4. 04
    Step 04
    Your savings = baseline − routed

    Every reply ships with a receipt: model picked, tokens in/out, what you paid, and what you saved vs. the frontier baseline. Numbers are token-accurate, not estimates.
