Build a bring-your-own-key workspace that estimates the cost of a request before execution, routes it to a suitable model within the user's budget, and tracks spending in ordinary currency rather than proprietary points. Users set project and monthly limits, receive warnings before expensive requests, and can switch providers without losing their working context. Begin with a narrow desktop workflow for research, drafting, and document analysis rather than attempting to replace every feature of the underlying providers.

AI providers increasingly combine subscriptions, usage allowances, and paid credits, while professionals are incorporating these tools into recurring work. The growing number of models and pricing structures makes independent cost control more valuable.
