faster customer insight synthesis
PM hire needed for early stage
professional templates
Wearing 5 hats and still needing to write structured specs
Customer call notes sitting in random Google Docs never getting synthesized
Engineering team asking for "real PRDs" but you do not have time to write them
Paying $20/month for ChatGPT that forgets your product every session
Upload interview recordings or transcripts. 1Brain transcribes audio and auto-analyzes pain points with severity and evidence.
See clustered pain points across all interviews. Know which problems are most severe and most frequent so your roadmap is data-driven, not intuition-driven.
Pick a template (PRD, one-pager, tech spec) and generate a structured artifact in minutes. Every claim cites real user evidence.
Export to Jira, Linear, or Markdown. Your engineering team gets specs grounded in evidence, not opinions, so they can build with confidence.
