for engineering teams ·one memory layer

Carry context across code, chat, and the agent.

Every incident, architecture call, and hard-won lesson lives in someone's head or a buried thread. 3ngram keeps them where your assistant can actually use them.

why it matters ·the shape of the problem

Cursor, Claude Code, GitHub, and Linear all hold different parts of the checkout-service story. 3ngram gives engineering teams cross-session memory so the next agent knows why retries moved to SQS before it rewrites them back to cron.

The AI in your editor can ship code faster than you can review it. What it cannot do on its own is remember that the checkout service moved retries to SQS because cron caused spiky cold starts, or that PR #482 shipped with rollback behind retries-v2.

3ngram is the persistence layer your tools forgot to build. Decisions get logged with the branch, PR, and production follow-up they belong to. When the next agent opens the repo, it carries context across code, chat, and the agent instead of starting from a blank session.

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

Agents repeat rejected architecture

The team moved retries to SQS because cron caused spiky cold starts. A week later, a fresh Claude session tries to simplify the flow by putting cron back.

3ngram: 3ngram surfaces the original ADR before the agent edits against it. The decision, rationale, and service context travel with the next coding session.

02

Rollback context lives outside the branch

PR #482 merged with rollback behind the LaunchDarkly key retries-v2. The next session sees the code, but not the operational escape hatch.

3ngram: GitHub context, PR notes, and captured decisions sit in the same shared work state. The agent can reference both the implementation and the rollback plan.

03

Production follow-ups lose their reason

On-call tightened alert thresholds from 0.5% to 0.2%, but that change becomes another line in the repo unless someone remembers the incident.

3ngram: 3ngram keeps the follow-up attached to the service and the decision history, so future work on checkout-svc starts with the production lesson included.

faq ·the questions we hear most
Is there a free tier?
Yes. The Free plan requires no credit card. It includes the MCP server, web dashboard, and unlimited memories and search under a fair-use usage budget. Upgrade to Pro for a higher budget and priority support, with AI answers and daily digests coming soon.
Does 3ngram replace CLAUDE.md files?
It complements them. CLAUDE.md is useful for static project instructions. 3ngram adds living memory that your AI reads and writes: ADRs, rationale, rollback notes, and follow-ups captured as the work happens.
Which coding tools does 3ngram work with?
Any MCP-compatible client: Claude Code, Claude Desktop, Cursor, ChatGPT, Codex, and more. Same memory across all of them.

Give Your Engineering Agents the Context They Keep Losing

3ngram keeps ADRs, PR notes, and production follow-ups available across Cursor, Claude Code, GitHub, and Linear.
