What it does for you

The problem

Writing help is split across subscriptions, so text, prompts and data sit in tools the buyer does not own.

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 tool switching while keeping writing data under the buyer's control. For writers, support teams and operators who write inside many apps, convert permitted text, selected models and approved prompts into source-linked drafts, translations and summaries with named-owner approval. The benefit is a testable hypothesis, measured through accepted drafts per writing hour and corrections after approval; do not assume that AI output alone produces business value.

Confirm the buyer's problem and scope, collect permitted text, selected models and approved prompts, then follow this sequence: 1. Invoke assistance from any app with a hotkey. 2. Correct grammar, spelling and formatting. 3. Translate text between languages. 4. Adjust tone for the target context. 5. Draft emails and context-aware replies. 6. Summarize websites, articles and documents. Resolve uncertain cases with qualified reviewers, approve source-linked drafts, translations and summaries, and measure accepted drafts per writing 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. One approved model set and one permitted input format; final tone, factual and publication checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.

Safeguards

Preserve author voice, source attribution, quotation accuracy and usage permissions. Authors approve substantive changes and publication scope. One approved model set and one permitted input format; final tone, factual and publication checks remain editorial. 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 model set and one permitted input format; final tone, factual and publication checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: invoke assistance from any app with a hotkey; correct grammar, spelling and formatting. Support the remaining modules with operator review: translate text between languages; adjust tone for the target context; draft emails and context-aware replies; summarize websites, articles and documents. 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

Buyer-owned documents, authorized email accounts and permitted research sources. Cloud storage, design-file import/export and publishing 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: Source-linked assistant panel, Prompt and model settings, Administrator console. Use a compact overlay for in-app assistance, a side panel for drafts and sources, and an admin view for keys, models, prompts, usage and audit. Let users compare draft versions and see which source text each suggestion came from. Display draft, changes requested and approved states. Provide a client or teammate preview link with comments anchored to the relevant passage. Make the task-specific outcome source-linked drafts, translations and summaries visible beside its evidence, review state and value baseline.
