Peec AI announced support for Muse Spark, the large language model powering Meta's newly launched personal AI agent, Muse. Announced on September 23, 2026 in Berlin, the AI Search visibility platform will now enable marketing teams to track brand visibility, sentiment, and cited sources in Muse Spark, the model powering Meta's new personal AI agent.
Demand for Muse Spark jumped sharply after Meta introduced it on September 8, 2026, describing Muse as "the world's first personal AI agent built for everyone." Meta AI already reaches billions of people across Meta's suite of apps, and with Muse, Meta is extending that presence into agentic AI.
Marketing teams and agencies using Peec AI can now measure brand visibility, sentiment, and cited sources inside Muse, alongside existing coverage of ChatGPT, Google AI Mode, Google AI Overviews, Gemini, Perplexity, Microsoft Copilot, Claude, GPT Search, DeepSeek, Qwen, Naver and Mistral.
"Tracking the Meta Spark LLM in Peec AI is the closest approximation brands have to estimate their performance in Muse, Meta's viral AI assistant," stated Malte Landwehr, CPO & CMO of Peec AI.
The addition reflects a broader shift where AI systems are moving from describing options to choosing and acting on them. As personal agents take on tasks like purchasing and negotiation, the sources and signals that shape those decisions become as important to brand visibility as citations in AI answers.
Muse differs from the chatbots and search engines that are currently on the market. Rather than only answering questions, it takes action on a person's behalf, booking travel, negotiating bills, and completing purchases through Link, Stripe's agent-focused checkout.
That shift matters for brands: being recommended by an answer engine is one thing, being the option a personal agent actually selects and pays for is another. Peec AI surfaces not only whether a brand is chosen, but why, using attribution tracking that identifies which signals and sources influenced an agent's decision.
Teams can benchmark visibility across both answer engines and agentic platforms side by side, from a single dashboard, helping marketing teams understand where they stand, what shapes how they appear and get recommended, and where to act.
The inclusion of Muse Spark positions Peec AI to track a new category of AI influence as personal agents become central to consumer purchasing and decision-making across Meta's ecosystem.
