TeachFX uses audio-based AI to transcribe and analyze classroom recordings, automatically segmenting speech by speaker type (teacher, student, group, silence) and surfacing instructional patterns such as open-ended question frequency, academic vocabulary usage, and specific praise counts. The platform operates as a SaaS application accessible via web and mobile, with no specialized hardware required — audio is captured from any standard device microphone. Individual teacher data remains private by default, while administrators and instructional coaches access anonymized, aggregated school- and district-level dashboards for trend analysis. TeachFX integrates a goal-setting and milestone system to drive communities of practice within schools and districts.
