AI app for it and development · no coding needed
Long-context reasoning assistant console
Reduce the time spent re-reading and re-explaining long material while keeping a source-linked record of every answer.
Made for: Teams that must reason over very large document sets and keep a reviewable record of how answers were reached

What it does for you
The problem
Long documents and multi-turn questions are spread across rented chat tools, so context is lost, sources are hard to trace and the workflow cannot be owned or audited.
What it gives you
Source-linked answer set with named-owner approval

Questions
Do I need to know how to code?
No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.
What does it cost?
The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.
How long does it take?
The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.
Can I change it to fit my business?
Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.
More detailsHow the AI works, safeguards and what to build first
Reduce the time spent re-reading and re-explaining long material while keeping a source-linked record of every answer. For teams that must reason over very large document sets and keep a reviewable record of how answers were reached, convert permitted documents, conversation history, tool results and review notes into a source-linked answer set with named-owner approval. The benefit is a testable hypothesis, measured through accepted answers per reviewer hour and corrections after approval; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect permitted documents, conversation history, tool results and review notes, then follow this sequence: 1. Hold a back-and-forth conversation with the model. 2. Process very large amounts of text at once so long documents can be understood. 3. Work through difficult questions that need step-by-step thinking. 4. Remember earlier parts of the conversation when replying later. 5. Use external tools or web sources to gather information while answering. Resolve uncertain cases with qualified reviewers, approve a source-linked answer set with named-owner approval, and measure accepted answers per reviewer hour and corrections after approval against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. Long-context limits, tool access and model behavior remain bounded; final factual and professional checks remain human. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve source attribution, quotation accuracy and usage permissions. Named owners approve substantive changes and publication scope. One approved document format and one bounded question set; final factual and professional checks remain human. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
What to build first
Pilot scope: One approved document format and one bounded question set; final factual and professional checks remain human. Implement one approved input format, a bounded representative case set and the first two task modules: hold a back-and-forth conversation with the model; process very large amounts of text at once so long documents can be understood. Support the remaining modules with operator review: work through difficult questions that need step-by-step thinking; remember earlier parts of the conversation when replying later; use external tools or web sources to gather information while answering. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.
What it can connect to
Customer-owned document stores, authorized web sources and permitted research databases. Cloud storage, identity providers and export destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Document intake and permissions, Conversation and reasoning workspace, Source-linked answer review and export. Use a thumbnail gallery for projects, a large central conversation canvas, and a right-hand panel for sources, tool results, constraints and comments. Let users compare answer versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant passage. Make the task-specific outcome source-linked answer set with named-owner approval visible beside its evidence, review state and value baseline.
