Stop re-explaining what you decided three weeks ago.

Roadmap calls get made in one thread and forgotten in the next. 3ngram holds the decisions, the commitments, and the stakeholder context that shaped them.

why it matters ·the shape of the problem

The onboarding v3 spec already answered the device-verification question. The activation metric was locked in Claude. The magic-link flow was accepted in Linear. 3ngram keeps those decisions connected so the next review starts from what is true, not what everyone remembers.

Product work is a chain of decisions. The onboarding v3 spec says to skip device verification on first sign-in and revisit it in v4. Claude helped lock the activation metric. Linear accepted ENG-1942 into scope. Cursor is where the next engineer asks why.

3ngram keeps those moments from becoming four separate versions of history. When the device-check debate reopens, the original thread is already there. Product leads stop re-explaining what they decided three weeks ago and start from the decisions, metrics, and accepted scope already on record.

friction points ·what breaks, and what 3ngram does instead
01

Old debates restart as new questions

A new engineer asks why first sign-in skips device verification. The answer is in the onboarding v3 spec, but the thread is three weeks old and the team is about to debate it again.

3ngram: 3ngram links the original decision back into the current work. The team sees the Google Docs decision, the rationale, and the v4 revisit note before the discussion drifts.

02

AI planning loses the metric

Claude helped draft the experiment plan, but the activation metric lives in that session. By the next review, the team remembers the experiment and not the measurement.

3ngram: The plan and metric travel together. Product leads can ask for the onboarding v3 context and get the experiment, activation metric, and source session in one place.

03

Scope gets detached from the tracker

Linear says ENG-1942 is in v3 scope, the spec says why, and the AI thread says how the team got there. None of those tools alone tells the whole story.

3ngram: 3ngram keeps the accepted scope tied to the decision history. The magic-link flow, the spec trade-off, and the next version follow-up stay connected.

faq ·the questions we hear most
Does 3ngram work with Linear and Google Docs?
Source sync for Linear and Google Docs is coming soon. Today, decisions made about those tools in your AI sessions land in the same shared work state — your assistant captures them over MCP as you work — so accepted scope and product rationale stay attached.
Can I use this for cross-functional visibility?
Teams is coming. Today you can run 3ngram as personal accounts that each capture their own decisions. When Teams ships, shared memory makes 'I didn't know we decided that' moments disappear across the org.
Can I choose what becomes product memory?
Yes. The product is built around explicit capture and typed memory — your assistant calls remember as you work — so you keep the decisions, commitments, and rationale that should survive the session.

Stop Re-Explaining Product Decisions

3ngram keeps the onboarding v3 story intact across Google Docs, Cursor, Claude, and Linear, so every review starts with the decisions already made.
