Five AI and Web Tools to Try in October: Prices and Uses

From the social network /dev/null to agent-assisted workflows in Rill, through short video with Spira Maxima and AI visibility audits via ReSO, several launches and highlights from October clarify their uses. Here’s what they offer, on which platforms, and at what prices when they are paid.

Access and Pricing: Free for /dev/null and Rill, $0.09/s for Spira, $599/month for ReSO

/dev/null is a free social network accessible via web browser and macOS. Rill, a browser for macOS still in beta, is free, but access to AI features requires a subscription to Claude Code. Spira Maxima, a video generation model, operates through a browser and charges $0.09 per second of generated video. ReSO, an AI visibility audit tool, offers a free audit followed by a monthly subscription of $599.

Key Features: Agents in the browser, ready-to-publish vertical video, AI audit, social network for developers

Rill allows users to request Claude Code or Codex directly from any web page: a keyboard shortcut opens a dialog box, the browser identifies the project, and transmits the page as context. The agents can also search for flights, group tabs by theme, or compare up to six tabs, and the tool, designed around AI, remains usable in a traditional manner. /dev/null draws inspiration from developer-specific practices, with posts called "commits," a "log" feed, and likes represented by stars; it adopts a functionality similar to X or Bluesky, allowing users to publish text, images, or polls, reply in threads, quote, follow accounts, and submit commits, provided they have a GitHub account. Spira Maxima creates ready-to-broadcast vertical videos: starting from a script and, if needed, graphic elements, it can add an avatar generated from a photo and a voice recording, then produces videos under 90 seconds tailored for TikTok, Instagram Reels, or YouTube Shorts, incorporating a virtual presenter, illustrative images, subtitles, and a soundtrack. ReSO operates in a sequenced approach: it begins by identifying and organizing questions directed at generative AIs at each stage of a purchase, submits these requests to ChatGPT, Perplexity, and AI Overviews, identifies citations, and performs a comparison with competitors, then conducts a site audit to reveal editorial, technical, and authority-related weaknesses; the tool then provides a prioritized weekly action plan. Talanoa presents emails in the form of conversations, in a style reminiscent of WhatsApp or Slack.

Traction Signals: 10,000 claimed accounts and Product Hunt in October

Five days after its launch, /dev/null claimed 10,000 users according to the timeline published on its site. The project had over 490 upvotes and was among the top three most popular on Product Hunt in October. Rill also generated interest on Product Hunt during the month of October.

Origins and Methods: 48-hour live sprint, browser bet, training, and marketing insights

/dev/null originated from a live sprint: four developers launched the project on October 15, aiming to build the social network in 48 hours with a go-live the next day at noon. Nuno Maduro attributes the buzz to the continuous streaming format, and Claude Code facilitated the realization. According to the creators of Rill, the web browser represents the most suitable interface for agents, and the founder indicates that his inspirations often come during recreational browsing sessions. Spira Maxima was launched on October 5 and, after an initial learning phase, is said to have been fueled by videos with high viral potential. ReSO is based on analyses from its co-founder Swati Paliwal, who has over twenty years of experience in marketing, noting that for about two years, the purchasing journey begins with questions directed at ChatGPT or Google’s AI; she claims that recommendations are limited to three to five brands and some references are absent from ChatGPT or Perplexity; she also asserts that measurement should be the first step for AI visibility.
