Chat assistants · alternatives
Knowster's friction points are caps and packaging. Free covers 1 website, 100 messages and 10 leads a month, and there is no analytics dashboard on it. Knowster branding stays on Free and Starter, so white-label means Pro at $99 per month. PDF and Word files are not read from Google Drive, and there is no annual billing yet.
ChatGPT is a general assistant for writing, research and analysis; it has a free plan and Plus at $20 per month, but it is not a website chatbot in our data, so it fits internal work rather than visitor support. Jasper is an AI content platform for marketing teams, with brand voice controls, agents and a Business tier. It has no free plan in our data and Pro is $59 per seat per month billed annually. Choose Jasper if your real need is marketing content, and stay with a chatbot product if visitor Q&A is the job.
