Overview

Nerra gives ChatGPT and the rest of your AI tools the same up-to-date picture of your company knowledge. Connect Slack, Google Drive, Gmail, Notion, Jira and your meeting notes once. Nerra reads them, picks out what matters (decisions, customers, owners, current plans) and keeps it current as things change. For example, your support AI agent can’t answer a customer's question, so it escalates it to a teammate. Once they reply, Nerra saves as knowledge, and next time your AI agents knows it. Nerra brings the right company context into your ChatGPT conversation, whatever the topic. Ask about a customer and you get their recent emails, meetings and deal status. Ask about a feature and you get the decisions, the discussion behind them and who's responsible. You can also ask ChatGPT to save something new. Nerra saves it along with who said it and when. After that, every AI tool connected to Nerra knows it. What you get: Your agents work from validated and current knowledge, so fewer answers rely on outdated docs One memory for every AI tool your team uses The current version of each fact, plus how it changed and why Answers about your company with a quote and a source link Saved notes your team can see, check and correct Built for teams that use several AI tools and agents and keep copying the same context from one to another.

Tools

answer_library

ChatGPT
Citation-grounded answer about the connected company, synthesized from its sources you are allowed to see. Use only for questions about this company's internal knowledge — not for general knowledge, other companies, or generic writing tasks.

get_company_context

ChatGPT
Distilled ACL-scoped overview of the company. Call when starting cold or for broad/meta questions. Filter by knowledge_class, confirmed_only, and area (defaults to your domains; cannot widen access). Items include knowledge_class, confirmed, and sensitivity.

get_entity_neighborhood

ChatGPT
Read the items linked to one item in the company's knowledge graph, limited to items you are allowed to see.

get_library_fact

ChatGPT
Read one fact from the company's knowledge library by its id, with its evidence, when you are allowed to see it.

knowledge_overview

ChatGPT
Use first for orientation or meta questions about what the Knowledge Library contains. Returns only the layers and categories you are allowed to see, with counts and last-updated metadata. Use structured_query for analytical field filters and query_library for fuzzy or conceptual search.

list_library_documents

ChatGPT
Enumerate ACL-visible Library documents, optionally filtered by source and folder. Returns the full visible count independently of the bounded result page.

list_library_folders

ChatGPT
Enumerate Library folders and sources from the complete ACL-visible document inventory. Use this for access/inventory questions instead of extrapolating from a query_library search sample.

query_facts

ChatGPT
Primary source of truth: curated, structured company knowledge (features, decisions, people, integrations, norms). Call this FIRST for questions about the company or product. Filter by knowledge_class, confirmed_only, and area (defaults to your domains; cannot widen access). Items include knowledge_class, confirmed, and sensitivity.

query_library

ChatGPT
Raw source excerpts (transcripts, documents, messages) from the connected company. Supporting evidence and quotes only — never the primary answer. Not for general knowledge or other companies.

save_knowledge

ChatGPT
Save a note to the Knowledge Library when the user explicitly requests it. Save the user's own words, verbatim (whitespace-trimmed), without summarising or adding conclusions, context or inferred details. Choose the closest theme_key for the note from the company's base themes: - team: People, roles, and organizational information. - customers: Customers, contacts, accounts, and relationships. - product: Products, features, roadmap, and product decisions. - sales: Deals, pipeline, pricing, and go-to-market activity. - support: Customer issues, requests, and service knowledge. - processes: Workflows, policies, procedures, and operating norms. - terms: Company terminology, definitions, and acronyms. - tools: Software, systems, integrations, and how they are used. - finance: Revenue, costs, billing, budgets, and financial operations. - notes: Free-form notes. If no theme fits, omit theme_key.

structured_query

ChatGPT
Use for analytical questions that require exact field predicates, ranges, null checks, or deterministic ordering over structured entities. Use knowledge_overview to orient first, and query_library instead for fuzzy or conceptual search. Person results include every ACL-visible canonical profile payload field, including departure dates when recorded.
