Build an AI-assisted engineering decision record tool that auto-captures context from PRs
The Problem
New engineers spend weeks digging through closed PRs and Slack to understand decision rationales, leading to slow onboarding and knowledge loss. Engineering teams at mid-to-large tech companies (500+ devs) face this, with tools like LinearB and Typo used by thousands but focusing on metrics over auto-captured context. Market data shows high adoption of PR-focused devtools, with 35 points and 60 HN comments signaling acute pain.[user query] Current spend on similar platforms ranges $9-25/dev/month.

How do you capture WHY engineering decisions were made, not just what?
Core Insight
Unlike LinearB, Typo, and Waydev which dashboard metrics and blockers, this tool auto-generates structured engineering decision records directly from PR context, enabling instant 'WHY' access without archaeology and filling the gap in decision preservation.
- Target Customer
- Solo founder to engineering manager at Series B+ SaaS companies (100-1000 devs), part of $10B+ devtools market where teams already allocate $15+/dev/month for metrics tools like LinearB.
- Revenue Model
- Freemium for small teams (<10 devs), then tiered per-developer pricing at $12/dev/month (Basic: auto-records), $25/dev/month (Pro: AI summaries + search), undercutting LinearB/Pro plans while premium matching enterprise needs.
Competitive Landscape
Starts at $15 per developer/month for Pro plan; Enterprise custom pricing.
LinearB focuses on engineering metrics like PR review time and size but does not auto-capture decision rationale or generate engineering decision records from PR context. It provides dashboards for performance measurement rather than contextual 'WHY' documentation for new engineers.
Custom enterprise pricing; contact sales (no public tiers listed).
Typo emphasizes delivery clarity, blockers, and workflow visibility from SDLC data but lacks specific auto-generation of decision records explaining WHY decisions were made in PRs. It prioritizes assistive ops over historical context capture for onboarding.
Starts at $9 per user/month; Team plan $15/user/month; Enterprise custom.
Waydev offers lightweight flow metrics and AI conversational insights from Git and project tools but does not automatically create structured decision records from PRs. It focuses on trend visibility and quick setup rather than deep decision archaeology.
Starts at $25 per developer/month; Enterprise custom.
Pluralsight Flow provides flow metrics and trend visibility for engineering teams but misses auto-capturing PR context into decision records. It emphasizes DORA metrics over preserving decision rationale for future engineers.
Willingness to Pay
- $15-$25 per developer/month
Teams using these platforms report reducing delivery surprises and rework, with leaders willing to invest in tools providing PR flow and engineering metrics clarity.
