## What is Decispher?

Decispher is the system of record for engineering decisions. It captures decisions, constraints, and rejected alternatives from Slack, GitHub, and Jira, records every AI coding session as a Branch Story, and serves it all back to your agents over MCP. Your AI coding tools get the memory they're missing; your team gets a reviewable record of why the code looks the way it does. In our A/B tests, agents working from Decispher context used 35-65% fewer tokens and stopped re-introducing approaches the team had already rejected. The open-source wedge, Decision Guardian, checks every PR against your recorded decisions: 2,100+ decisions surfaced at PR time so far.

**Best for:** Engineering teams that use AI coding agents (Cursor, Claude Code, Copilot) and are tired of re-explaining the same context to every agent, every task.

- Capture engineering decisions
- Improve AI coding efficiency
- Streamline onboarding for new engineers

## What is ideaFast?

Finding real customer pain points on Reddit usually means reading hundreds of threads.

IdeaFast does that for you.

Point it at a topic or a set of subreddits, and it finds recurring complaints, groups them by problem, scores the pain level, and shows the exact quotes and thread links as evidence.

It doesn't stop at Reddit either, it also looks at Hacker News and the wider web to spot patterns across communities.

Found a problem worth solving? IdeaFast generates startup ideas, business models, and risks so you can evaluate them quickly.

No guessing. No endless scrolling. Just validated problems backed by real people.

Free to explore. Paid plans start at $9/month.

**Best for:** Entrepreneurs and indie hackers looking to validate startup ideas.

- Startup idea validation
- Problem discovery
- Market research
