Startup DaVoice sues Perplexity AI over stolen wake word technology. Voice-AI startup DaVoice has sued Perplexity AI in federal court, alleging the company stole its wake word technology, including source code and training data, after the two companies collaborated. Perplexity calls the claim baseless and says their agreement protected its right to build competing tech. A Swiss voice-AI startup says Perplexity took its wake word code, its training data and its architecture, then kept building without it. Perplexity says the contract let it do exactly that. DaVoice, the voice-AI startup that does business under the legal name SyteMLLabs, filed a heavily redacted complaint on September 24 in the U.S. District Court for the Northern District of California, accusing Perplexity AI of stealing trade secrets tied to wake word technology, the software that lets a device sit there listening for a phrase like "Hey Siri" without streaming every sound it hears to the cloud. The case is DaVoice v. Perplexity AI Inc., No. 3:26-cv-10909, and DaVoice is represented by Davida Brook and Ian Crosby of Susman Godfrey, according to Courthouse News Service. The two companies had worked together. That's the part that makes this messier than a typical copycat claim. DaVoice, co-founded by Ofer Fryman and Helge Voss, says it entered into confidential agreements with Perplexity to license its wake word system, technology the startup says runs at above 90% accuracy and undercuts rivals on price. According to the complaint, Perplexity absorbed DaVoice's proprietary source code, inference logic, network architecture, training approach and training data during that collaboration, then allegedly built its own version using what DaVoice calls the false and misleading promise of a lasting, lucrative partnership. Perplexity isn't backing down. Jesse Dwyer, the company's chief communications officer, called the suit "a baseless attempt to claim ownership of standard wake-word technology," and said the agreement DaVoice signed expressly protects Perplexity's right to develop its own "similar, equal or competitive products or services." In other words: Perplexity's defense isn't that it didn't build a competing product. It's that the contract said it could. Wake word detection sounds like a small piece of engineering, but it's the gatekeeper for every voice assistant that exists. Get it wrong and the device either ignores you or listens to everything, which is its own privacy problem. Get it right and you've built the front door to whatever the assistant does next. Perplexity has spent 2026 pushing hard into that territory, expanding its Comet browser's voice features and its assistant mode, and a startup with real automotive and IoT customers, DaVoice has worked with Volkswagen and IoT company Samsara, is exactly the kind of technology a fast-moving AI company might want to shortcut rather than build from scratch. Anthropic's full threat report reveals Xiaomi wasn't acting alone: six other Chinese AI labs, including Alibaba, DeepSeek and Moonshot, ran similar campaigns to extract Claude's outputs, with Moonshot caught secretly routing live user queries through Claude without disclosure. - chinese AI labs copying Claude without attribution - how Anthropic caught multiple companies stealing Claude That's the pattern showing up across the industry this year. Smaller, specialized firms build a hard piece of infrastructure, hand it to a bigger platform under an NDA or a pilot deal, and then find themselves competing against something that looks a lot like their own work. Whether that's illegal depends entirely on what the paperwork actually says, and paperwork is exactly what this case will turn on. DaVoice's complaint is redacted precisely because the underlying agreements, and what they do or don't permit, are the whole fight. Frankly, both sides can't be right about what that contract says, and a judge in San Francisco is going to have to read it line by line to find out. If Perplexity's version holds, this becomes a cautionary tale for startups who license their core technology to a much larger partner without locking down what happens after the relationship sours. If DaVoice's version holds, it becomes a cautionary tale for platforms that treat a vendor's source code as raw material once the ink is dry. Perplexity hasn't filed a formal answer to the complaint yet. The case now sits in the Northern District of California, where trade secret disputes involving AI companies have become a fairly regular occurrence this year, and where the next filing will likely be Perplexity's motion to dismiss or its own answer laying out exactly what that licensing agreement permitted.

Advanced micro devices (AMD) stock gains on Perplexity AI collaboration. Key highlights. Table of Contents * Shares of AMD advanced 2% Friday following the reveal of innovative AI capabilities developed with Perplexity. * The collaboration integrates Perplexity's Portable Computer into Windows machines equipped with AMD Ryzen AI Max processors. * PC owners can execute AI operations locally on their devices, preserving Perplexity Computer credits for other uses. * This development extends AMD's agentic PC initiative that gained momentum in 2025. * Analysts maintain a Strong Buy consensus on AMD with a mean price target of $648.07. Shares of AMD experienced a 2% uptick Friday after the semiconductor manufacturer revealed a collaborative AI tool development with Perplexity. The positive market response reflected investor enthusiasm for AMD's continued expansion in AI-enhanced computing devices. At the heart of this announcement is Perplexity's Portable Computer technology. The tool is now compatible with Windows computers powered by AMD's Ryzen AI Max processors, which includes the Ryzen AI Halo developer platform. This integration enables PC users to execute artificial intelligence operations directly on their hardware. Users can establish automated recurring tasks without consuming Perplexity Computer credits for processing. This latest development represents the culmination of AMD's multi-year vision. The company introduced its initial AI-capable PCs in 2023, featuring an integrated neural processing unit within an x86 architecture chip. The following year, 2025, saw AMD accelerate its commitment to agentic computing. These advanced systems enable AI agents to operate locally on the device instead of depending exclusively on cloud infrastructure. AMD leadership weighs in on innovation. AMD executive Jack Huynh addressed the partnership announcement mid-week. Huynh serves as senior vice president and general manager of AMD's Computing and Graphics Group. "We're entering a new era of computing, where personal AI transforms the PC from a tool into an intelligent partner," Huynh said. He emphasized that computers are evolving into systems capable of understanding, reasoning, and acting in collaboration with users. According to Huynh, the Ryzen AI Max processor family enables AI models and intelligent agents to execute directly on personal computers. This architecture provides users the autonomy to work locally while maintaining access to more powerful cloud-based processing when circumstances require it. The processor design merges CPU and GPU capabilities with an expansive unified memory architecture. This configuration enables local AI model execution to run concurrently with standard applications without performance degradation. Perplexity contributes its model infrastructure and agent technology to the partnership. The companies jointly assert that this collaboration transforms agentic PCs from a specialized concept into a viable solution for mainstream consumers. Analyst sentiment on AMD stock. The strategic timing of this product launch carries significance. While cloud-based infrastructure currently dominates AI processing, AMD is positioning itself for a shift toward local task execution as user preferences evolve. This forward-looking strategy explains Friday's market enthusiasm. Should local AI adoption accelerate as AMD anticipates, the company stands to gain substantial advantages from its early-mover position in this segment. Financial analysts maintained an optimistic outlook on AMD stock even before this announcement. The consensus rating stands at Strong Buy, supported by 30 Buy recommendations and six Hold ratings compiled over the previous three-month period. The average analyst price target for AMD stock reaches $648.07. Notably, zero Sell ratings exist among the tracked analyst community. The Perplexity collaboration provides additional validation for investors monitoring AMD's artificial intelligence PC roadmap.

Swiss startup accuses Perplexity AI of stealing passive listening tech. Perplexity called the lawsuit a "baseless" reach for ownership of standard wake-word technology, which is used to recognize spoken activation phrases in devices like Amazon's Echo. (CN) - A Swiss startup accused Perplexity AI, the operator of an artificial intelligence-powered search engine, of stealing its trade secrets under the guise of developing a long-term business relationship. SyteMLLabs, which does business under the name DaVoice, filed a heavily redacted complaint Thursday in San Francisco federal court. DaVoice, the company says, has developed proprietary technology that allows a device to continuously listen for a specific word or phrase that activates it, with over 90% accuracy at below-market prices. When the "wake" word is detected, the device wakes up and begins processing subsequent commands. A wake-word system, the company said, serves as a critical gatekeeper for the use of AI assistants, which require exceptional accuracy in recognizing the target word or phrase, a low rate of false wakes and an ability to conserve device energy. DaVoice claims it entered into a series of confidential agreements with Perplexity last year to license its technology to the AI company, only for Perplexity to misappropriate DaVoice's trade secrets, including proprietary source code, inference logic, network architecture, training approaches and training data, to build its wake-word system. "Perplexity used the false and misleading promise of a potentially long-term and lucrative business partnership to lure DaVoice into executing the mutual confidentiality and nondisclosure agreement and master subscription agreement - the contracts subject to which DaVoice disclosed its trade secrets to Perplexity," DaVoice said. "It then breached those contracts by, among other things, using the technical expertise and know-how that DaVoice provided to Perplexity to accelerate Perplexity's development of its own wake-word implementation." The Swiss company accuses Perplexity of stealing trade secrets under both federal and California law, breach of contract and fraudulent inducement, among other claims. DaVoice seeks compensatory damages for lost profits, reasonable royalty damages and exemplary damages for willful and malicious misappropriation of its trade secrets. DaVoice is represented by attorneys from Susman Godfrey LLP. "This is a baseless attempt to claim ownership of standard wake-word technology," Jesse Dwyer, Perplexity's chief communication officer, said in an email. "Recognizing a spoken activation phrase is not unique to DaVoice, and the agreement DaVoice signed expressly protects our right to develop our own 'similar, equal or competitive products or services.'" "That is exactly what we did, and we look forward to prevailing in court," Dwyer added. San Francisco-based Perplexity, which reportedly received funding from Amazon founder and executive chairman Jeff Bezos and Nvidia, is no stranger to litigation. The company has been sued by the New York Times over scraping and repackaging the newspaper's articles, as well as Rupert Murdoch's Dow Jones and New York Post and separately by Encyclopaedia Britannica and Merriam-Webster. Last month, Perplexity prevailed before the Ninth Circuit, lifting a lower court order that had blocked its shopping assistant tool - which can compare products, prices and reviews on behalf of users - from accessing the Amazon website.
