What TeachFX does

TeachFX is an AI-powered classroom discourse analytics platform that records K-12 lesson audio and converts it into private, non-evaluative feedback for teachers on instructional practices such as talk-time ratios, open-ended questions, wait time, academic vocabulary, and specific praise. The core product is a mobile and web app in which a teacher records a lesson; proprietary machine-learning models perform speaker diarization, transcribe the audio, and detect seven high-leverage teaching practices, producing a structured class report within minutes. The product surface has expanded beyond the single-teacher workflow to include a Lesson Transcript with word-level navigation, a PLC Studio for collaborative teacher communities, and a Zoom integration that extends capture into virtual classrooms.

The underlying technology combines speech/audio processing with natural language processing in a proprietary multimodal diarization system that fuses audio and text signals to identify who is talking — research that has been published at AIED 2025 and SEGA 2025. The platform is FERPA, COPPA, and NIST 800-171 compliant and explicitly designed so teachers own their data; aggregated school-level metrics are surfaced without exposing individual teacher performance.

TeachFX monetizes through annual, quote-based subscription licenses sold at the school or district level, with pilots available for subsets of teachers before district-wide commitments. The company sells directly to K-12 superintendents and instructional leaders, primarily in US public school districts (Atlanta Public Schools, Salt Lake City, Iron County, Lincoln County, South Fayette Township, Charleston County, East Aurora UFSD, Hemet Unified, Anaheim Union, among others), with an installed base of 8,500+ teachers as of September 2024 and cumulative funding of approximately $13.7M including a $10M round in September 2024.

Emerging players

• Eduaide.ai: Eduaide is an AI teaching assistant that helps K-12 teachers generate lessons, assessments, and instructional content. It targets the same teacher productivity and instructional improvement pain points as TeachFX but focuses on pre-class planning rather than in-class discourse analysis.
• Schoolytics: Schoolytics provides classroom and student data analytics for schools using Google Classroom and other LMS platforms. It serves the same K-12 data-driven instruction use case as TeachFX, though it focuses on assignment and engagement data rather than audio discourse analysis.
• Mursion: Mursion provides AI- and VR-simulated classroom environments where teachers practice instructional techniques with virtual students. It targets the same teacher professional development use case as TeachFX, focused on improving instructional practice and student engagement.
• MagicSchool AI: MagicSchool AI is a fast-growing AI tool suite for K-12 teachers (lesson planning, differentiation, assessment generation). It is an adjacent AI-for-teachers platform that competes for the same teacher attention and district AI budgets, though it does not analyze live classroom discourse.

Direct peers

• Edthena: Edthena is an AI-powered video coaching platform for teachers that lets educators upload lesson videos and receive timestamped feedback from coaches. Like TeachFX, it serves K-12 districts and focuses on scalable teacher observation and instructional improvement workflows.
• Swivl: Swivl provides classroom audio and video capture hardware/software that enables teachers to record lessons for self-reflection, coaching, and feedback. It is the most direct comparable to TeachFX's audio capture and discourse analysis approach, targeting the same K-12 teacher observation and professional development use case.

Broad incumbents

• Curriculum Associates (iReady): Curriculum Associates' iReady is a widely adopted K-12 adaptive assessment and instructional analytics platform, including the acquired Motion Math studio. It competes for district-level instructional improvement budgets alongside TeachFX at much larger scale.
• GoGuardian Teacher: GoGuardian is a well-funded K-12 classroom management and student safety platform owned by Lightspeed Systems. While its core is screen monitoring, it overlaps with TeachFX in giving teachers visibility into student engagement and discourse in digital classrooms.
• Newsela: Newsela is an established K-12 instructional content platform used widely in US districts for differentiated reading and engagement. While its core is content delivery, it competes for the same district-level student engagement and equity-of-voice budgets as TeachFX.
• Panorama Education: Panorama Education is a leading K-12 data analytics and student success platform used by thousands of US districts. It overlaps with TeachFX at the district-level instructional analytics layer but does not capture or analyze in-class audio data.
