“'OpenAssistantGPT is open source and powered by open source software'; Pro plan includes "Remove 'Powered by OpenAssistantGPT'" implying branding on lower tiers”Quote from the site
New-user source: Viral (Built-in sharing). Similarweb 2026-09: the top channel is direct at 40.4%, followed by organic search (estimated at about 44.7% beyond the measured top-channel share) and referral about 9%, with paid at 0%; there are only 131 keywords, mainly the brand keyword openassistantgpt, and the long-tail terms are scattered. The website is an open-source project, and the chat window on the free/low-price tiers carries a Powered by OpenAssistantGPT badge (only Pro can remove it), so embedding on users' websites becomes a passive source of exposure. Early on, the founder posted on Product Hunt, Hacker News (a Show HN post), DEV.to, and GitHub, all with very small responses (HN 2-3 points, PH 3 votes); the founder did not fill in a channel on TrustMRR.
