The rationale layer

Every tool logs the what. None of them log the why.

Tacit Paradigm captures the reasoning behind decisions in the apps your team already uses: Stripe, Jira, Gmail, and Notion. It stays permanent, searchable, and available to people and AI agents.

Hi Alex, appreciate the detailed quote. That said, the +18% lift is going to be a tough sell with our new finance team. Is there any flexibility here?

Hi Talia, counter-proposal: 12% on the new baseline plus a 6-month onboarding discount, which brings your effective YoY spend up only ~6%…

Why 12% + a 6-month discount instead of the flat 18%?

Past renewals where you softened the headline lift averaged a 14% higher acceptance rate.

Q3 Roadmap · Payments

Sprint 14 commitments

Cut self-serve refund MVP from this quarter; deferring to Q4.

Promote 3DS reliability from "stretch" to P0.

Maintain refund-engine SLA at 99.95% through end of quarter.

✦ Tacit Paradigm · capture rationale AI

You cut a P0 commitment from the roadmap. Why?

Roadmap cuts on payments docs in the last 6 months were almost always tied to upstream incidents.

How it works

Capture, store, serve.

Capture

A Chrome extension and macOS app prompt inline where decisions happen. Silent on routine actions, it only asks when something is genuinely new.

Store

Every rationale becomes a node in a searchable decision graph. The reasoning stays even after the person who made the call leaves.

Serve

Past rationales surface back when they matter: to people in a dashboard, and to AI agents over MCP.

Integrations

For AI teams

Your decisions, agent-readable.

The rationale graph speaks Model Context Protocol. Point Claude Code, Cursor, or any MCP client at it and your agents act with the context of every decision your team has explained. Each capture is also a labelled (question, answer, context) pair, a fine-tuning dataset by construction.

Local inferenceScreen content never leaves the laptop.
