This submission is for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built. The author created Thread, a voice-first AI thought companion for capturing ideas that surface before they are fully formed. The user speaks naturally, and Thread records the audio, transcribes it with ElevenLabs Scribe, and stores both the original transcript and AI-generated summary, categories, possible action, and question.
Thread then checks for other related thoughts by converting transcripts into embeddings and searching the posted timeline, using pgvector to find up to five relevant earlier thoughts. A Gemma model then examines whether these relationships could be helpful. The AI does not decide what the user intended but offers possible connections, implications, and questions that could help the user explore those ideas further. The original words remain visible along with the AI interpretation.
