How usage works
Measured in what things actually cost.
Windows, not tokens
Each plan includes usage over a rolling window plus a weekly ceiling, measured in real cost rather than opaque message counts. Routine days never come close.
Auto stretches your allowance
Messages routed by Auto count less against your usage than hand-picking a heavyweight for everything. The router saves us money, so it saves you allowance.
Your connections never count
Anything you run on your own models or accounts is between you and your provider. The app even shows you what you saved.
Questions, answered plainly.
What is Heuricity?
Heuricity is a chat app that gives you every frontier AI model in one subscription. A router picks the right model for each message and shows you why, and you can bring your own models too.
How is this cheaper than subscribing to one AI app?
Single-model subscriptions send everything, including trivial questions, to one expensive model family. Heuricity routes each message to the model that will genuinely nail it, which is often a fast, inexpensive one. Cheaper routing is passed on as lower prices. Most single-model subscriptions cost more than all of Heuricity.
Which models are included?
The included catalog carries current frontier models from the Claude, GPT, Gemini and Grok families, alongside fast models for everyday work. The catalog grows as new models ship. Connections add anything else, from Mistral and DeepSeek to hundreds of models via OpenRouter.
Can I use my own models?
Yes. Connect a model running on your own machine or your own cloud, or connect an account you already have with a provider. Connected models appear in the same menu and work with the router, and usage on them is never counted against your plan.
What happens when I hit a usage window?
Plans include generous usage measured over a rolling window plus a weekly ceiling. If you reach the wall, the app says so plainly and gives you real outs: keep going on your own connections, top up, or wait for the window to roll. Nothing fails silently.
Do you train AI on my conversations?
No. We never train language models on your content. With your consent we use routing records, things like which model was picked and whether you regenerated, to tune our routing. The privacy page explains exactly who can see what.
Is there a free way to try it?
Yes. New accounts get one month of Pro free, no credit card required.
Can I cancel any time?
Yes. Plans are monthly and cancelling takes effect at the end of the billing period. Deleting your account really deletes your data.
