AI does the heavy lifting, people stay in charge

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.

What your team sees

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.

Accounts and administration

Project ownership, connected account versions, reader comments, approval states, usage allowances, revision limits, download history and a rights record for supplied material. Add organization access boundaries, named reviewers, usage caps, data retention controls, export logs and explicit approval for external actions.

Integrations and data access

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.

We build with our own AI software development factory, so most implementations take days to a few weeks of creation time, not months. You see working software at every step, and exact timing depends on availability.

1. 1

   Scoping call

   Day 1

   Thirty minutes on your process, your data and how you want to run it: for your own team, or for your clients. You get a fixed scope and price for the MVP.

2. 2

   MVP

   5 days

   One buyer segment, one recurring use case; first modules: connect popular email clients for sending and managing messages; suggest grammar and style improvements in real time. Manual review in the loop. Built by our AI software factory.

Why we start with an MVP

An MVP, or minimum viable product, is the smallest version that your users can actually work with. It is not a cheap version of the full solution. It is a test, built to answer the questions that decide whether the rest is worth building.

1. Pick the riskiest assumption. Here: will professionals and small teams who write email and newsletters and subscribe to many sources use it to solve "writing email and newsletters and keeping up with subscribed sources is split across separate tools, so messages, drafts, digests and inbox actions are managed in different places"?
2. Build only what tests it. One team, one use case, a few core modules. People do the rest by hand for now.
3. Run a paid pilot. Agree quality and outcome thresholds before the pilot using this measure: Approved drafts per writing hour and digest items read per week.
4. Measure, then decide. Track approved drafts per writing hour and digest items read per week; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase. Then expand, change course or stop, with evidence instead of opinions.

MVP scope for this solution. 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.

After the MVP. Once paid pilots prove usefulness, automate repeatable reviewed steps and add one verified source integration. Expand supported inputs and case volume only after new evaluation cases pass. Build reusable customer configurations and recurring value reports around reviewed drafts, scheduled sends and a consolidated digest. Retain the explicit scope boundary: One connected mailbox provider and one newsletter source format; final sending, tone and editorial checks remain human.

What the build depends on. Mailbox connection and preview, asynchronous generation jobs, editable version history, reviewer access and tested export formats. High-fidelity delivery requires specialist editorial QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One connected mailbox provider and one newsletter source format; final sending, tone and editorial checks remain human.

A planning range to start the conversation, not a quote. You pay per phase, so you can stop after the MVP.

Running costs per month

A rough indication of monthly hosting and AI model costs once it is live, not tested. Real costs depend on usage, file sizes and the models chosen.

Selling it to your own clients: the go-to-market playbook

Pricing to test

Test a USD 300-1,500 fixed pilot for one defined mailbox and source package. Offer a monthly production allowance after repeat demand. Quote complex multi-source or team workflows separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewed drafts, scheduled sends and a consolidated digest. Recurring fees must specify volume, review depth and integration support. For exchanges, test a disclosed coordination or successful-service fee rather than holding customer funds. Reprice only after measuring real delivery labor; platform-build cost is separate from a commercial pilot fee.

Message to test

Reduce the number of separate tools used to write, schedule and read email and newsletters. Demonstrate a concrete reviewed drafts, scheduled sends and a consolidated digest using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Professionals and small teams who write email and newsletters and subscribe to many sources professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.

Lead magnet

A reviewed sample reviewed drafts, scheduled sends and a consolidated digest from a small authorized input set, with a transparent calculation of approved drafts per writing hour and digest items read per week and no promised savings.

The first 30 days

1. Week 1: interview five professionals and small teams who write email and newsletters and subscribe to many sources and inspect a recent example of writing email and newsletters and keeping up with subscribed sources is split across separate tools, so messages, drafts, digests and inbox actions are managed in different places.
2. Week 2: prepare a consented or synthetic demonstration of the three task modules.
3. Week 3: seek one bounded paid pilot with agreed baseline and acceptance criteria.
4. Week 4: measure approved drafts per writing hour and digest items read per week, reviewer effort and repeat-purchase interest. This is a demand-validation plan, not a thirty-day full-product delivery promise.

Paid pilot

Agree quality and outcome thresholds before the pilot using this measure: Approved drafts per writing hour and digest items read per week. Continue only if the buyer accepts the actual output, the intended job outcome improves without unacceptable errors, and measured delivery cost fits willingness to pay. Revise or stop if access is unavailable, qualified review cannot be provided, or apparent savings disappear after corrections and support. Use held-out cases when comparing model quality; use a properly reviewed comparison design before making causal claims. Record missing cases and negative results alongside successful outputs.

Success metrics

Approved drafts per writing hour and digest items read per week; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.

Retention and expansion

Repeat the workflow when the buyer again needs reviewed drafts, scheduled sends and a consolidated digest. Retain permissioned settings and reviewed examples, report realized value honestly, and sell increased volume or adjacent approved workflows only after contribution margin and quality remain acceptable.

Why clients would pick it

A reusable library of approved templates, filters and digest examples, together with reliable delivery for a narrow writing and reading niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for professionals and small teams who write email and newsletters and subscribe to many sources. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

DeepLetter, LaterOn.email, LaterOn, Sofon, Daily Nugts and Inbox Zero are used today as separate rented subscriptions. Compare this product with the buyer's present method on approved drafts per writing hour and digest items read per week. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Generation attempts, mailbox and feed processing, storage, reviewer hours, client revision rounds and licensed source content. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of reviewed drafts, scheduled sends and a consolidated digest. Track cost per accepted output, including correction work, unsuccessful cases and support.

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.
