Mochii
A browser assistant that combines multi-model chat, document analysis, form help, memory, and custom knowledge-based chatbots.
About Mochii
Mochii brings several language and image models into a browser sidebar, with web and mobile access available too. It can summarize webpages, analyze PDFs and other documents, assist with web forms, generate images, remember preferences, and power custom AI roles or knowledge-based chatbots. The free Personal plan includes 0.15M tokens per month and community support. Paid tiers increase token allowances and add faster responses, more customization, stronger support, and, on Premium and Ultimate, custom model keys. It suits people who want AI tools beside the page they are using. Monthly token limits, Chrome and Edge extension support, and tier-specific features are the main tradeoffs.
