MultitaskAI is a custom chat interface for users who want to interact with models from OpenAI, Anthropic, and Google Gemini within a single dashboard. Instead of paying for multiple separate subscriptions, users provide their own API keys and pay for the tokens used according to their provider's pricing.
The tool is designed for professionals, researchers, and developers who require more flexibility than a standard chat web page. It supports split-screen multitasking, where multiple models can generate responses simultaneously to help users compare different outputs.
Additional features include tools for parsing uploaded files, creating specialized AI agents with custom instructions, and rendering Mermaid diagrams. For those with strict data requirements, the software supports self-hosting on static hosting platforms.
Buyers should confirm current API pricing with their chosen AI providers, as those costs are separate from the MultitaskAI license.
