Attie is a standalone AI assistant built on the AT Protocol and powered by Anthropic's Claude, released by Bluesky's former CEO Jay Graber — who stepped down specifically to build it. The app lets users design custom social feeds using natural language, without writing a single line of code. You can ask Attie to surface posts about specific topics, filter out content you hate, or create algorithm-driven feeds for any niche interest. Because Bluesky runs on the open AT Protocol, Attie has immediate access to your social graph, interests, and interaction history across the entire ecosystem — not just Bluesky but any ATProto app. This gives it a contextual richness that proprietary AI assistants like Grok (X) or Meta AI can never achieve on their platforms. It's invite-only with a waitlist, but the longer-term plan is to let users vibe-code their own social apps. The early reception was fascinating: Attie became the most-blocked account on Bluesky after Bluesky's own announcements bot — suggesting meaningful user anxiety about AI intrusion in the open social graph even when the tool is explicitly opt-in.

Spira AI deploys AI influencer agents that live inside your brand — monitoring trends in real time, generating on-brand content, and publishing across social channels while you focus on higher-leverage work. Each agent has its own defined voice, persistent memory, and personality profile, behaving more like a dedicated social media hire than a content generation tool. The platform runs agents on real devices rather than API-only execution, which means accounts behave more like organic human users — important for platform algorithm treatment and engagement rates. Spira catches breaking trends, adapts content to each channel's format norms, and executes 24/7 without the burnout cycle of human social teams. The team behind Spira includes veterans from Meta and Robinhood who previously built networks of 100K+ autonomous AI personas. They're applying those multi-agent systems and agentic network-building chops to brand marketing. The promise: consistent brand presence and trend-reactive content at a fraction of the cost of a full social media team. The risk: authenticity concerns and platform ToS grey areas around automated account behavior.
Reviewer scorecard
“The AT Protocol's open data model is the unlock here — Attie can see your entire social context across apps, which is something a walled-garden AI assistant fundamentally cannot do. This is the right architecture for personal AI at the social layer.”
“Running agents on real devices rather than pure API calls is a smart technical choice that avoids bot-detection and platform shadowbanning. The persistent voice and memory architecture means content actually stays on-brand rather than drifting across sessions — a real problem with generic AI content tools.”
“The most-blocked-account stat tells you everything — even Bluesky's ideologically aligned user base is spooked by AI having read access to their social graph. Invite-only with no clear monetization path suggests this is a feature, not a company.”
“Automated posting at this level is a ToS violation waiting to happen on most major platforms, and the 'real devices' angle doesn't change that. Beyond legal risk, AI-native influencer content tends to be algorithmically promoted but audience-rejected once people recognize the pattern. Brand trust takes years to build and seconds to lose.”
“This is the first demo of what AI-mediated social looks like on an open protocol. If it works, the implication is that any user can have a completely personalized feed without relying on corporate algorithmic decisions. That's a genuine paradigm shift from Twitter/Instagram's engagement-optimized black boxes.”
“The distinction between 'human content' and 'AI content' is dissolving fast — within 18 months, every brand will have some form of AI social agent. Spira is building the infrastructure layer for that shift. The question isn't whether AI agents will run brand social, it's who builds the best ones first.”
“As a creator, controlling your own feed algorithm without needing to understand engagement optimization is huge. Being able to say 'show me posts from small illustrators, no sponsored content, heavy on process videos' and just getting that — this is the tool I've wanted since RSS died.”
“For indie brands and solo creators who can't afford a full social team, this is genuinely compelling. The trend-aware content generation means you're not just scheduling posts — you're participating in real conversations. The voice memory feature is what makes it feel like a real brand presence rather than a bot.”
