MultitaskAI

About MultitaskAI

MultitaskAI is a bring-your-own-key chat client for OpenAI, Anthropic, Google Gemini and other leading models, sold as a lifetime licence rather than a subscription. Because you supply the API keys, conversations go straight from your machine to the provider and you pay provider rates instead of a marked-up seat fee — the pricing page shows worked examples, putting a hundred typical messages at a couple of dollars on GPT-class models and under a dime on a Flash-class one. The name comes from the interface: a split-screen view that runs several conversations at once, so you can put the same question to two models side by side and compare, or keep a long-running thread open while starting something new. Requests queue and complete in the background, so you are not blocked waiting on a slow reasoning model. Per-model settings, keyboard shortcuts, saved prompts, custom agents with their own data, file upload and parsing, vision, Whisper transcription, inline generation, canvas, charts and MCP support fill out the feature set. It runs online or self-hosted, installs as a PWA with offline support, syncs across devices, and ships light and dark modes — a lightweight app rather than an Electron shell. The site claims over a thousand customers. The catch for buyers is that the lifetime licence price does not render without JavaScript, so check the current figure on the pricing page before committing.
