What is InfernoAI?

InfernoAI is an AI chat bot tool. A no sign up, browser based chat client that connects to OpenAI, Anthropic, Gemini and any OpenRouter model using your own API key, with folders, tags, full text search, text to speech and a one time lifetime license.

InfernoAI is a browser based chat frontend that puts OpenAI, Anthropic, Gemini and any other model routed through OpenRouter into a single conversation window. Nothing is installed and no account is created: the app opens in the browser and asks for an API key from OpenRouter, which is the provider that actually serves the models. From there the user picks a model from the OpenRouter catalogue and starts typing, switching between providers as the task requires rather than juggling several vendor tabs. Organization is the part that separates it from a bare API playground. Conversations can be sorted into folders, labelled with tags and located later through full text search, so a long archive stays navigable. Advanced parameters such as max tokens, temperature, top p and top k are exposed for users who tune model behaviour, while a text to speech option reads replies aloud and a DALL-E 3 plugin generates images from inside a chat. Custom model entries are accepted, so a route that is not in the default list can still be wired in. The practical case is a heavy chat user who already pays for model access and objects to a second monthly bill. Because the app is bring your own key, usage is billed by OpenRouter at API rates instead of a fixed subscription, and InfernoAI itself is sold as a one time license. Privacy follows the same logic: chats and API keys are held on the local device, and the stored data can be exported, imported or erased by the user. No ChatGPT Plus or Claude Pro plan is needed to reach those models through OpenRouter. The free version is the full feature set with a single chat open at a time, which is workable for evaluation but awkward for anyone who keeps several threads going. A license removes that cap and, per the site, grants lifetime access including future premium features, with one key activatable on up to five devices. Credits for the models themselves are separate and paid to OpenRouter. Alternatives include first party chat apps with subscriptions and desktop clients that bundle keys, whereas InfernoAI is narrow by intent: a local data chat client whose only recurring cost is the API usage behind it.
