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 number of separate tools used to write, schedule and read email and newsletters. For professionals and small teams who write email and newsletters and subscribe to many sources, convert connected mailbox messages, saved templates, subscribed newsletter feeds and topic choices into reviewed drafts, scheduled sends and a consolidated digest. The benefit is a testable hypothesis, measured through approved drafts per writing hour and digest items read per week; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect connected mailbox messages, saved templates, subscribed newsletter feeds and topic choices, then follow this sequence: 1. Connect popular email clients for sending and managing messages. 2. Suggest grammar and style improvements in real time. 3. Adjust message tone between formal and casual. 4. Offer pre-made templates for common occasions. 5. Save favorite templates and drafts for reuse. 6. Schedule emails for chosen send times. 7. Remind users to follow up on important conversations. 8. Track email performance and engagement in a dashboard. 9. Combine multiple newsletters into a single email. 10. Set digest delivery frequency as daily, weekly or monthly. 11. Explore and subscribe to new newsletters. 12. Query specific newsletter content through a chat-like assistant. 13. Adjust font size and type for readability. 14. Work on mobile and desktop. 15. Subscribe to specific people or topics. 16. Aggregate content from podcasts, articles, books, newsletters and videos. 17. Deliver a concise summary of chosen interests. 18. Compare large-scale opinions on a topic on demand. 19. Categorize email by content and sender priority. 20. Archive, delete or move multiple emails at once. 21. Set personalized filters and rules. 22. Capture reader replies to improve content relevance. Resolve uncertain cases with qualified reviewers, approve reviewed drafts, scheduled sends and a consolidated digest, and measure approved drafts per writing hour and digest items read per week against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the writing, scheduling and digest modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One connected mailbox provider and one newsletter source format; final sending, tone and editorial checks remain human. 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 connected mailbox provider and one newsletter source format; final sending, tone and editorial 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 connected mailbox provider and one newsletter source format; final sending, tone and editorial checks remain human. Implement one approved input format, a bounded representative case set and the first two task modules: connect popular email clients for sending and managing messages; suggest grammar and style improvements in real time. Support the third module with operator review: adjust message tone between formal and casual. 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 mailboxes, authorized newsletter feeds and permitted content sources. Cloud storage, email client import/export and delivery destinations. Start with file exchange and validate destination specifications before promising direct sending. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Connected mailbox and source list, Writing and digest workspace, Schedule and delivery. Use a left list for messages, sources and drafts, a large central editing and digest canvas, and a right-hand panel for tone, templates, filters and comments. Let users compare draft versions and digest editions side by side. Display draft, scheduled, sent and approved states. Provide a reader preview link with comments anchored to the relevant item. Make the task-specific outcome reviewed drafts, scheduled sends and a consolidated digest visible beside its evidence, review state and value baseline.
