Tools using Claude Sonnet 4.6

  • Poe
    AI-powered chat for effortless writing and coding.
    Open
    They recently changed to a “point based system” where free users get 3000 daily point. Subscribers get 100,000,000 points monthly plus the 3000 daily. Each model has a wide range of costs. Some are cheap and some are more expensive. There is no longer unlimited messages for subscribers. It has since sparked an outrage among the community with many ending their subscriptions and moving away from Poe.
  • Venice
    Private, uncensored AI conversations and image generation.

    Been really using Venice. UI is clean, I like the live counter while waiting for replies or images, it's small but useful. The replies come in fast without the usual filters you see elsewhere. It's more to the point, feels casual and doesn't waste your time. Good pick if you just want something straightforward without the privacy trade offs.

    Hey 👋 — founder of Pinci here. Most AI tools hand you the controls and expect you to figure out the rest, the right model, the right prompt, the right settings. That's fine if you're an AI power user. It's a wall if you're not. Pinci works the opposite way. Each agent is a specialist creative director in one domain: Jules directs product video, Paul directs product photography, Tommy handles brand design. You describe the result you want in plain language. The agent decides how to get there, coordinates the right tools, and hands you a finished, ready-to-publish asset. No prompts. No model-picking. No AI knowledge required. You get 300 free credits on signup, enough to see exactly what I mean on your own product today. I'd love your honest feedback: which agent would you try first, and where does it fall short? 🙏

    New: Topical Authority, own the whole topic, not one lucky post Analyze your existing content for free: https://meev.ai/tools/topical-map-generator Meev now turns your blog into a living topical authority map, so you rank and get cited for a subject, not a single post. Auto-maps your whole blog into themes. Every article you've published gets grouped into topics (a pillar guide plus its supporting posts), so you can see at a glance what you own deeply and what's scattered. Flags your "orphan" posts. Pages that belong to no theme and build zero authority get surfaced, so you know exactly what to strengthen or merge. Two honest scores per theme, not vanity metrics. Built = how completely you've covered the topic. Proven = whether search is actually rewarding it yet. Gives young sites early credit. Proven blends your real Google Search Console wins, so early long-tail rankings count months before they'd otherwise show up. Plans each week around the next gap. Instead of scattered one-off posts, Meev finishes one theme (pillar first, then the missing angles) before moving to the next weakest high-value topic. Reflects real demand, and links itself together. It pulls the actual cluster of searches around your topics, auto-links supporting posts to their pillar, and guards your pages from competing with each other. Counts every page you own, including posts Meev didn't write, and the map maintains itself as your library grows. Wins AI search, not just Google. Connected, complete topic coverage gives ChatGPT, Perplexity, and Google AI Overviews more reason to retrieve and trust you. Try it free: map any site into a topic cluster map in ~30 seconds, no signup, with our free Topical Map Generator. 👀 Coming soon, an AI agent for your SEO & GEO questions. Ask Meev anything about your search and AI-search visibility and get answers grounded in your own connected data (Search Console, rankings, competitors, and your AI-citation history), not generic advice, with the next move teed up for your one-click approval.
