Compound your own thinking.

Strategy takes shape across many conversations. 3ngram keeps the reasoning, so each session builds on the last argument instead of restarting it.

why it matters ·the shape of the problem

Pricing strategy took shape across Claude, ChatGPT, co-founder pushback, and a Google Docs decision. 3ngram lets founders build on yesterday's reasoning instead of relitigating the same per-seat versus usage debate.

A founder’s context window is the company. Strategy starts in Claude, gets challenged in ChatGPT, turns into a Google Doc, and comes back weeks later when the question still matters. The AI can keep up for a session. It cannot keep up for a quarter.

3ngram is the memory layer for operators who cannot afford to relitigate their own thinking. The arguments you have already had with your AI count. Yesterday’s pricing rationale, today’s co-founder pushback, and the final v0.4 decision all become one thread the next session can build on.

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

The reasoning is older than the current session

Claude argued against per-seat pricing 42 days ago. Today you open a new session and have to reconstruct the whole prosumer argument before anything useful happens.

3ngram: 3ngram hands the model the prior thread before you ask. The new session starts with the usage-with-a-floor rationale already in context.

02

Co-founder pushback gets separated from the model

ChatGPT helped revisit the landed cost model after your co-founder pushed back on usage pricing. That correction matters, but it lives in a different session from the original argument.

3ngram: 3ngram connects the pushback to the decision history. The next pricing pass includes both the original thesis and the pressure test.

03

Strategy docs lose the debate behind them

The pricing v0.4 doc shows three options and one decision, but not the argument that got you there. Six months from now, the doc is all that survives.

3ngram: 3ngram keeps the Claude thread, ChatGPT model, and Google Docs decision together, so the document is backed by the reasoning that produced it.

faq ·the questions we hear most
Can my whole team use this?
Teams is coming. Today you can run 3ngram as personal accounts that each capture their own context, and everything you build now carries forward. When Teams ships, shared memory extends the same record across the founding team.
How fast can I get started?
A few minutes. Sign up, connect your first MCP client, and start building memory. Add more MCP clients as you go; source sync integrations are coming soon.
Is my data safe?
Yes. See the security page for the full pledge: what we read, what we store, and what we will never train on.

Make Your AI Compound With Your Thinking

3ngram keeps founder strategy threads connected across Claude, ChatGPT, and Google Docs, so the next session starts from the last real decision.
