·64 views

Walrus Sessions 8 is a live hackathon running from September 18 to October 9, 2026, focused on building chatbots that retain context across conversations using the Walrus Memory SDK on mainnet. Participants must create or upgrade a chatbot that stores and recalls user context, deploy it in a real environment, and document the integration with evidence of it working. The competition is open to any use case, including customer support, tutoring, and sales. A total of $2,500 in WAL prizes is on offer, with separate award tracks for the best chatbot, best article, non-Claude/GPT models, and bug bounties requiring no chatbot submission.

New free tool combines multiple buy-now-pay-later plans into one view

A developer has built BNPL Stack Untangler, a free web tool that lets users combine their buy-now-pay-later plans into a single overview. Users enter each plan's provider, item, installment amount, remaining payments and due dates. The tool displays total amounts owed across all plans, upcoming payments by week and month, and a shared calendar of installments. It also highlights weeks when several payments fall due together and shows which plans carry late-fee risk. The creator designed it to work with any provider rather than connecting to individual company APIs, and it requires no account to use.

Are AI Assistants Challenging Google's Dominance in Search?

Google still dominates the search market with roughly 91% of global share, according to Statcounter data from October 2026. Yet many people are now turning to AI tools like ChatGPT, Perplexity, and Gemini for conversational, consolidated answers rather than clicking through multiple links. A Gartner survey reported that 51% of consumers had changed their research habits because of generative AI, often using more specific, conversational queries. The article argues that the shift reflects changing expectations around convenience, follow-up interaction, and personalization rather than simply a new platform choice. It also notes that market share measures only traditional search, not the broader ways people now discover information through social media and AI assistants.

How paid membership tiers model access: plans, products, and what they unlock

A builder of the TribeCrafter community platform describes how paid access works there, starting from what each tier unlocks rather than what it costs. Free, Monthly, and VIP plans are shown granting differing access to feeds, private groups, premium posts, and courses, so content can be moved between tiers without changing the content itself. Communities can sell recurring plans, one-time products granting lifetime or fixed-period access, or both, and access is removed automatically when a membership ends. Payments go directly to each creator's own Stripe account via Stripe Connect, with the platform taking no fees beyond Stripe's processing charge. Each community also runs on isolated infrastructure, including its own database, cache, search index, and storage, so member data is never shared across communities.
