Pyka

Autonomous electric airplanes

Pyka’s goal is to provide society with a new form of safe, clean, and cost-effective transportation enabled by autonomous electric aviation. To get there, we’re taking a different approach than most. We're applying our technologies to every industry where autonomous electric aircraft can be useful, starting with the highest value and most dangerous jobs. In doing so, we're building game-changing products manufactured at scale, while perfecting the safety, reliability, and capabilities of our autonomy engine and electric propulsion systems. We design, develop and manufacture an ecosystem of technologies including proprietary flight control software, avionics, high power density motors, motor controllers, batteries, and custom carbon-fiber composite airframes. Today, we supply autonomous electric aircraft for cargo transport and crop protection to real-world customers across four separate continents and have secured industry-first regulatory approvals from the FAA. Our cargo aircraft enables remote connectivity, enhances express delivery networks, and ensures fast and reliable shipping of critical supplies to areas in need. Our crop protection aircraft offers agricultural services providers and farmers an autonomous tool to make aerial application safer, more precise, and less harmful to surrounding environments. Both vehicles are highly economical to operate, easy to deploy, and significantly reduce C02 emissions in their respective industries. What you work on at Pyka makes people’s lives better now and brings the future of electric aviation one step closer each day.

Quantstruct logo

Quantstruct

AI documentation engineer – test & autoimprove stale product docs

Quantstruct automatically creates and improves product documentation, implementation guides, and changelogs for API & SDK products, web-based enterprise software, and internal applications. Quantstruct identifies gaps in your knowledge base based on each product release or unfulfilled customer query. It uses multiple AI agents to search existing knowledge sources, test existing docs for validity and style guidelines, and clicks, scrolls, and uses enterprise software through a web browser to generate docs with embedded screenshots and video recordings. Quanstruct is available as a cloud service to start, targeting technical writers, content writing, professional services, and product teams. Traditional generative AI tools risk hallucinating critical API & SDK fields, even with RAG based approaches. Purely agent-based approaches risk providing unpredictable output that can diverge from desired documentation processes. Finally, no company’s review and publishing workflow is the same. Quantstruct is the easiest way to onboard and customize AI agents to continuously improve your documentation based on your customer needs and product evolution. https://quantstruct.com
