It's on page 11 of a file nobody can find. - 01 ### Folders no search can reach Contracts live in shared drives and inboxes, filed once and never found again. The knowledge is there; getting it back is not. - 02 ### An afternoon per question “What did we agree to?” means opening files one by one until something looks right. The answer costs hours and still arrives unchecked. - 03 ### Confident AI that cites nothing General assistants answer fluently about documents they have never read. Sounding right is not the same as being right, and nothing links the claim to a page. 02 How it works ## No citation, no claim. Every sentence resolves to a document and a page you can open. Turn on “Answer only from your documents” and nerix must quote a passage for every claim, or tell you it can't answer instead of filling the gap from what a model happens to remember. - 1 ### Bring what you already have Drop in a folder of contracts, reports or scans. Every file is read, summarised and filed against the client, supplier or colleague it belongs to. - 2 ### Ask in the language you think in In your own language, across the whole library at once. Search by exact words and by meaning, side by side. - 3 ### Get the page, or a straight no Each sentence carries the number of its source; open it and the passage is highlighted. When your files don't hold the answer, it says so. With “Answer only from your documents” on Example workspace What does our NDA with Helios Ventures say about IP? Your documents don't cover an NDA with Helios Ventures, so I won't guess. Upload the agreement, or ask me to search the web. I'll ask before anything leaves your organisation. Most AI tools can't say “I don't know”. This one is built to. 03 The tools ## One account. A family of AI tools that read the same library. Every tool works from what you have already filed, so each one answers from your own documents and shows where it found things. - Live ### Chat Ask anything across your files and the web. Every sentence numbered to its source.

Every file gets a short summary, a visible index status, and a place in a folder tree built around your clients, staff and suppliers. It also gets a passport with its type, area, own date and status, and links to the documents it is connected to. app.nerix.ai · Northgate Partners Example workspace Documents 6 - Master Services Agreement, Acme Industrial Acme-MSA-2026-signed.pdf · 2.3 MB Ready Net-45 payment terms, liability capped at 12 months of fees, 90-day termination for convenience. - Statement of Work, Q3 platform migration Acme-SOW-Q3-migration.docx · 180 KB Ready Four milestones with acceptance criteria; 20% held against final acceptance. - Rate card 2026 Acme-rate-card-2026.xlsx · 46 KB Ready Blended day rates by role, volume discounts from 500 booked days. - Framework agreement, logistics services Nordline-framework-logistics.pdf · 3 MB Ready Inland freight across three regions; late-delivery penalties; disputes go to arbitration. - RFP response, Delta Retail (final) Delta-RFP-response-final.pdf · 5.6 MB Processing No summary yet. Searchable by words now, by meaning soon - Delivery note, Steelline (scan) steelline-delivery-note-scan.jpg · 3.3 MB Failed No summary yet. Could not be read. Upload it again. **Fig. 2** The library in the example workspace. Each row shows the file type, the size, the summary the AI wrote, and whether the file is searchable yet. A file that failed says so; it is never hidden. ### Two searches, side by side. Not blended, on purpose. Keyword search finds the exact words, even in a file that is still being indexed. Meaning search finds the idea, even when the words differ. Blend them into one list and you cannot tell why a result ranked where it did. Keep them apart and you can trust both. Query termination notice Example workspace Keyword The literal words, highlighted 48 ms - Master Services Agreement, Acme Industrial …a 90-day termination -for-convenience clause applies after year one… - Standard clause library Pre-approved wording for liability, indemnity, termination and data protection… Meaning The closest passages, scored 210 ms - Master Services Agreement, Acme Industrial 87% match Auto-renews unless either party gives 60 days' notice before the anniversary date. - Framework agreement, logistics services 81% match Either party may exit at the end of a season with thirty days' written notice. **Fig. 3** The same query in both panes of the example workspace. The words found on the left, the passages closest in meaning on the right. The two lists are not merged into one. - 01 #### Exact when you need exact A clause number, a name or a figure is found by its letters. No guessing. - 02 #### Close when the words differ “Termination notice” also finds “either party may exit with thirty days' written notice”. - 03 #### You see which one found it Every hit says which search produced it, so a ranking is never a mystery. 05 The Sheet ## Drafts with a history you can rewind. What the assistant writes does not vanish into a chat. Documents, proposals, code, HTML pages, spreadsheets and diagrams land in the Sheet. Every edit is a version, and restoring an old one never erases a newer one. The history only grows. Export when it is ready. - ### Documents, offers and handbooks Procedures, policies and plans written from your own files, chapter by chapter when they are long. - ### Code and HTML Shown rendered or as source. HTML previews run sandboxed. - ### Spreadsheets, charts and diagrams Flow charts, org charts and charts of your own numbers, checked before you see them. Draft Example workspace ### Proposal, Orbit Freight renewal This proposal renews the supply agreement for a further twelve months at the blended rates in Appendix A. Service levels carry over unchanged, including the shared SLA on inland delivery. Versions - 3 Restored from version 1 nerix Current - 2 Edited by hand You Restore - 1 First draft nerix Restore Restore adds a version. Nothing is overwritten. Export PDF DOCX Exports are counted in your credit history and in the audit log. **Fig. 4** A draft in the Sheet of the example workspace, with its version history on the right. Version 3 was made by restoring an earlier text: the restore added a version and removed none. For teams ## Meetings, tasks, checks, a help desk and team chat, in the same place. The same workspace your documents and answers live in. And if your business needs more, we build it. - [Meetings Agenda, live notes, minutes and action items, filed as tasks.](https://nerix.ai/product/meetings) - [Tasks and projects Tasks, cases and projects as a list, a board, a table or a calendar.](https://nerix.ai/product/work) - [Help desk A help desk with queues, macros, a portal and response targets.](https://nerix.ai/product/desk) - [Team chat Team chat in spaces and topics, where a message can become a task.](https://nerix.ai/product/spaces) - [Checks Audit readiness from about 90 frameworks, checks on a plan, issues that become tasks and business reviews.](https://nerix.ai/product/audits) - [Built for you We add features, connectors and workflows to your workspace.](https://nerix.ai/product/custom) [See every product](https://nerix.ai/product) 06 Agents ## Not one model. A team with a plan. A coordinator breaks your question down and hands the parts to specialists. Each specialist has a declared list of tools and a model tier matched to its job. You can see who did what, and what it cost. Which of our contracts renew this year, and what is the exposure? Example workspace Coordinator Splits the question into five steps and picks who takes each. 1 → 5 - Specialists Tier - 01 Librarian Finds the contracts and the pages that matter. Economy - 02 Analyst Works out the dates, amounts and totals. Standard - 03 Reviewer Judges the risk in each clause. Strongest tier. Premium - 04 Researcher Looks outside the library, only after you allow it. Economy - 05 Drafter Writes the summary and the next steps. Standard Turn record Every step names the agent, the model that answered and the credits spent. **Fig. 5** One question handled by the coordinator and five specialists in the example workspace. The reviewer, the one that judges risk, runs on the strongest tier. Each step is listed in the turn record with its credits. - 01 ### Delegation is declared An agent can only call the agents on its own list. - 02 ### The right model for each job Cheap models do the finding. The strong one does the judging. - 03 ### Nothing is hidden The record shows each step, so the bill is never a surprise. 07 Control ## Your policy, enforced by the server. Not by a checkbox. Write a rule once and it applies to every conversation. Skills are named procedures the assistant reaches for when a question matches. Any tool that would send data outside your organisation asks first, by default. Example workspace ### Rules Standing instructions for everyone in the organisation. An enforced rule is applied by the server, so a member cannot turn it off. Organisation rule Enforced Quote the clause exactly as written, then explain it in one sentence. Members cannot switch this off. ### Skills A named procedure you write once. It runs when a question contains one of its trigger words. Skill Contract risk review Trigger words - risk - review - exposure ### Tool permissions Each tool is set to allow, ask or deny. Anything that leaves your organisation starts on ask. Tool - library:read_document Allow Stays inside - research:web_search Ask first Leaves the organisation - authoring:generate_document Allow Stays inside **Fig. 6** Three controls from the example workspace: an organisation rule that members cannot switch off, a skill with its trigger words, and the permission for each tool. 08 Models ## Every leading model. One account. The caveats printed. nerix sends each question to a model that fits it, and every answer names the model that wrote it. Where a maker processes data, and whether it may keep it, is shown at the same weight as what it is good at. - ### Mistral AI 10 models Chat Search Scans Runs in: European Union - Provider does not train on data - Provider may keep data Hosted in the European Union. The default for document answers. - ### nerix server 2 models Search Ranking Runs in: Our own server, France - Provider does not train on data - Provider keeps nothing Runs on nerix's own server in France: search and ranking never leave it. - ### Anthropic 7 models Chat Runs in: United States - Provider does not train on data - Provider may keep data - ### Google 9 models Chat Images Search Runs in: Worldwide - Provider does not train on data - Provider may keep data - ### DeepSeek 3 models Chat Runs in: China - Provider may train on data - Provider may keep data Processes requests in China.

Your app calls one hub instead of each AI company, with one key per server and one balance for everything. - ### Signed both ways Each request is signed with your server's own key, and each answer is signed by the hub. Nothing in between can change either, and an old request cannot be replayed. - ### Every model, one format The common chat format with a small nerix object added. Change the model name, not your code. Fallbacks happen only when you list them. - ### One balance for every app Credits, not invoices from six companies. Usage per customer and per feature, and each answer says what it cost. - ### Your keys stay yours Provider keys live in the hub's vault, never in your apps. Your server keeps its own private key; the hub stores only the public half. example.ts // one client per process: it holds your server's key import { RespireSoftAI } from '@respiresoft/nerix' const ai = new RespireSoftAI() const answer = await ai.chat.create({ model: 'mistral/mistral-large-latest' , // or an alias: 'fast' messages: [{ role: 'user' , content: 'Summarise this contract' }], nerix: { tenant: 't42' , feature: 'summaries' }, }) answer.nerix.resolved // the model that actually answered answer.nerix.cost // { credits: 2, ... } **Fig. 8** A real call through the Node SDK: the answer says which model replied and what it cost.

Facts you can check instead. - 1 We never train models on your documents, and neither does Mistral, the EU provider a new workspace uses. Any other provider shows its own terms before you switch it on. - 2 The audit log is append only. Not even an owner can edit or delete an entry. - 3 Your credit balance is the sum of an append-only ledger. Nothing in it is ever edited or removed. - 4 DeepSeek's caution about processing in China is printed inside the product, on the model picker itself. - 5 Delete a workspace and it is erased for good once its 30-day grace period ends. - 6 With “Answer only from your documents” on, the server refuses answers without a source. The refusal is a feature. When customers vouch for us in public, they will be here, named and with their permission. Until then: claims you can check.

Is nerix an AI? + Yes. nerix.ai is an AI system: the answers are written by AI models. That is why every answer shows its sources and names the model that wrote it, so you can check it. What happens when my documents don't contain the answer? + With “Answer only from your documents” on, nerix must quote a passage for every claim, and says it can't answer rather than filling the gap from a model's memory. A confident guess about a contract is worse than no answer. How do the numbered sources work? + Each sentence carries the number of its source: a document and a page, such as “page 11 of 34”, with the quoted passage. Open the number to see the passage on its page. Is my data used to train AI models? + We never use your documents to train models, and neither does Mistral, the EU provider a new workspace uses. What each other model maker may do with requests is shown on the models page and in the product before you switch it on, at the same weight as what the model is good at. Where is my data stored? + In the European Union, for every workspace: the service runs on servers in France, and files and backups are kept in the Netherlands. Other regions are not available yet; when one is, this answer will say so. Which AI models can I use? + A new workspace is EU only: its documents and questions go only to Mistral, hosted in the EU, and to models on our own server. An owner or admin can also switch on Anthropic, Google or DeepSeek; speech (Soniox, Cartesia, ElevenLabs) and pictures need a provider outside the EU, so they work once one is switched on. Each maker's cautions are printed in the product, including that DeepSeek processes data in China. Which languages does it work in? + Ask, search and get answers in the language you work in, with the same page-level sources. A library that mixes languages is normal, and each file is read in its own language. What does a question cost? + It depends on the model you choose, and the app shows the price before you send. The exact cost is settled afterwards from what the model really used. Storing a document and making it searchable is free; its short summary costs a few credits, and reading a scanned page or exporting a file costs more. Every entry is in your credit history. What if I run out of credits? + AI work stops: the spending cap is on from the start, so nothing is charged beyond your plan, and you get a warning at 80%. To keep going, an owner turns the cap off and adds a credit pack, from €10 for 100,000 credits, or you move to a larger plan. How do I start? + Open the app and create an account. The free plan is one seat and 3,000 credits a month. It stops at that limit, so it never costs anything. ## Ask your documents something hard. Create an account, add a contract, and ask the question that usually costs an afternoon. Start free Talk to us
