NerraNerra: The Shared Memory Layer Your AI Stack Has Been Missing
Your team runs Claude for drafts, a Jira agent for engineering, a custom responder for support — and each one starts from zero. It doesn't know what the others decided, doesn't know the policy that changed last Tuesday, and will confidently retrieve the rule that was superseded two months ago. Nerra is a company context engine built to fix this: a live memory layer constructed automatically from your existing tools — Slack, Jira, CRM, email — and served to every agent over MCP. Knowledge is typed by kind (confirmed decision, inferred pattern, superseded fact), agents write learnings back with human approval, and nothing starts from zero again.

Key Takeaways
- 1Auto-builds shared context from your real data — Slack, Jira, CRM, email — no wiki to maintain, no manual upkeep
- 2Serves the same context layer to Claude, ChatGPT, Cursor, and custom agents via the MCP protocol
- 3Knowledge is typed: decisions, inferred patterns, and superseded facts are tracked separately — not just stored

- 5Self-hosted option available with an advertised ~15-minute install — keeps all data on your own servers for data residency requirements
The Problem: Every Agent Starts From Zero
Picture Thursday: your team updates the refund policy. Monday: a support agent confidently returns the old Notion page — unchanged, ranked highest by recency, wrong. The pattern scales to any workflow where more than one AI agent touches the same domain. Claude drafts a strategy in one session, a Jira automation ships work in another, a critical decision lands in Slack, and by next week every agent is back to square one. The knowledge is somewhere — in logs, in docs, in messages — but nothing connects it to the next agent that needs it. The result is hallucination from outdated documents, repeated context-setting overhead, and agents that can't build on each other's work. Nerra's argument is that this is not a prompting problem or a model capability problem — it is a missing infrastructure problem. There is no shared company memory that both humans and agents can read from and write to as it changes.
How the Context Engine Works
Setup starts by connecting Nerra to the tools your team already uses: Slack, Jira, a CRM, email, support platforms. Nerra ingests this data and builds a Knowledge Library — not a document dump, but a structured layer that understands what each piece of knowledge represents. The layer is then exposed to every AI agent you run via the MCP (Model Context Protocol), which means Claude, ChatGPT, Cursor, and any custom agents query the same source rather than each maintaining private memory. When an agent completes work, it can write results back into the Knowledge Library with source attribution. Those write-backs go into an approval queue requiring human sign-off before they are promoted to the shared layer — so the context compounds through real work, not just through documents that sit unread. Nerra's own get-started page frames self-hosted setup at roughly 15 minutes, which is short enough to test against a live Slack workspace before committing to any process change.
Why Stale Context Is Worse Than No Context
Most context systems treat information as a blob of text with a timestamp. Nerra classifies each piece of knowledge by what kind of thing it is: a decision someone confirmed, a pattern inferred from data, or a fact that was once true and has since been superseded — with a record of what superseded it, when, and why. For an AI agent, this distinction is not cosmetic. Returning a policy that changed three months ago is not just a retrieval failure — it is an active wrong answer that looks correct. By tracking state transitions rather than just storage timestamps, Nerra can surface "this was the rule, it changed, here is the decision that changed it" rather than surfacing the old rule with high confidence. That provenance chain is what separates a context engine from a smarter search box, and it is the architecture that makes agent coordination across policy-heavy workflows actually reliable.
Self-Hosted or Cloud: One Product, Both Models
Nerra ships both a hosted cloud version and a self-hosted option described as the same product at the same price — which removes what is usually a forced tradeoff between managed convenience and data control. For organizations with data residency requirements — teams that have made architectural commitments about where company data lives — this option removes the typical barrier to adopting a SaaS context layer. No formal compliance certifications are publicly advertised; the primary lever is that data never leaves your perimeter on the self-hosted path. The cloud version is the default starting point for teams without those constraints and requires no infrastructure management. Both paths start for free.
Who Gets the Most from Nerra
Nerra is built for organizations already running multiple AI tools that are hitting the ceiling of what isolated agents can accomplish. If your team uses Claude for drafts, a Jira automation agent, and a custom support responder, and these three have no shared context about what the company has decided, you are the target user. The value of a shared context layer is proportional to the number of agents reading from it — small teams running a single assistant are not the right fit yet. The self-hosted option makes Nerra credible for compliance-conscious industries where cloud-based AI tooling is otherwise blocked. Check Nerra's current connector list against your specific stack before committing — the published integrations cover the most common tools (Slack, Jira, CRM, email, support), but niche vertical tools may not be connected yet.
Ratings
No migration, no wiki to fill in, no setup overhead — connects to tools already in use and builds context automatically
Starts for free with no advertised feature cap; typed knowledge, write-back, and self-hosted at the same price as cloud is a strong package — pricing at scale is not public, worth confirming before full rollout
Typed knowledge classification with state transitions (decisions / inferred patterns / superseded facts + provenance chains) is a genuinely novel approach to shared AI context
Typed knowledge with state transitions, MCP serving, write-back approval, and self-hosted in one package leads the category on depth; published connector list (five categories) is the only meaningful breadth gap
Responsive early-stage team; documentation is present and growing
Best For
Engineering and product teams already running multiple AI agents across Slack, Jira, CRM, and support channels who need those agents to share context rather than each starting from zero. Strong fit for organizations with data residency requirements that need a self-hosted option.
Not Ideal For
Teams running a single AI assistant or just starting with AI tooling — the shared context layer pays off only when multiple agents are in production. Also not suited to teams whose stack relies heavily on tools Nerra doesn't yet connect to.
Pros
- + Typed knowledge classification tracks decisions, patterns, and superseded facts separately — agents get context that is still true, not just recent
- + MCP protocol support means any compliant agent (Claude, ChatGPT, Cursor, custom) reads from the same layer without custom per-tool integrations
- + Agent write-back with human approval and scoped read/save rights per agent type — a support agent cannot overwrite strategic decisions; company knowledge compounds through real work
- + Self-hosted option is the same product at the same price — resolves the cloud vs. data residency tradeoff without a feature penalty
- + No migration required — connects to tools already in use rather than requiring documentation to be rebuilt from scratch
- + Conflict surfacing and gap identification built in — the system flags when context is contradictory or missing, not just when it's stale
Cons
- − Published integrations cover the common stack (Slack, Jira, CRM, email, support) — if your team's critical tools sit outside this set, check connector availability before committing
- − Pricing details are not publicly displayed — the free start is clear but cost at scale requires a direct conversation to understand
- − Write-back value compounds only when teams close the approval loop — organizations without a culture of reviewing and promoting agent learnings will leave the compounding benefit on the table
Verdict
Nerra addresses the infrastructure gap that emerges the moment an organization moves past a single AI tool: agents that can't share context with each other, that return outdated decisions as current facts, and that require the same setup work every session because nothing persists between them. The typed knowledge layer — distinguishing decisions from patterns from superseded facts, with provenance chains for each — is the most technically distinctive approach in this emerging category. That is architecture that solves a different and harder problem than document search. The self-hosted option at the same price as cloud removes the barrier for data-residency-conscious teams. Pricing at scale is not public yet, which is reasonable for a product at this stage — the right sequence is validate fit first, then have the pricing conversation. The free start means the evaluation path is: connect your tools, let the Knowledge Library build from your existing data, and run an agent query against your own history. If you are coordinating three or more AI agents across your business, Nerra is worth starting now before the context debt compounds further. Visit nerra.ai to start for free.
Frequently Asked Questions
How is Nerra different from giving every agent the same system prompt?⌄
A system prompt is static — it captures what you knew at the time you wrote it. Nerra's context layer is live: it updates as decisions are made, tracks when facts are superseded, and lets agents write back what they learn. You do not need to manually update a prompt every time policy changes; the layer updates itself from your connected tools and flags the change with a provenance record.
Why not just use a shared Notion, Claude Projects, or a RAG connector?⌄
Shared wikis and RAG connectors return the document that matches best by recency or similarity — they do not know whether that document is still correct. If a policy changed and the update never made it to the wiki, your agent returns the old policy with high confidence. Nerra tracks knowledge state: when something is superseded, it records what superseded it, when, and why. Claude Projects and direct connectors give agents access to documents; Nerra gives them access to decisions — including the ones that made previous documents wrong.
Is there genuinely a free tier, or is "start for free" a trial?⌄
Both Cloud and Self-Hosted are listed as "start for free, same product, same price" — there is no trial timer or feature cap advertised anywhere on the Nerra site. Pricing at scale is not publicly displayed, so the cost conversation happens once you've validated fit. The free start is real; the unknown is what comes after.
What tools does Nerra currently connect to?⌄
The published connector list covers: CRM, Slack, Jira, support platforms, and email. On the agent side, the MCP protocol means Claude, ChatGPT, Cursor, and any custom MCP-compliant agent can read from the context layer without custom per-tool integrations. Check nerra.ai for the current connector list as integrations are actively added.
How does write-back approval work in practice?⌄
When an agent completes work and writes a result back into the shared context layer, it enters an approval queue rather than immediately joining shared memory. A team member reviews the write-back and approves or rejects it. Approved items enter the Knowledge Library with source attribution. This keeps the compounding loop honest — agents can contribute, but humans stay in control of what becomes company truth.
Does self-hosted mean fewer features or higher cost?⌄
According to Nerra, the self-hosted version is the same product at the same price as the cloud version. The distinction is infrastructure responsibility: cloud is managed, self-hosted runs on your own servers. No public compliance certifications (SOC 2, GDPR, etc.) are advertised — the primary data control lever for compliance-conscious teams is the self-hosted data residency guarantee ("your data never leaves your perimeter"). Teams with formal audit requirements should verify certification status directly.
