AI Client Communication Hub with Smart Briefing

Problem and target customer

Why this exists

Customer problem

Account owners prepare for client calls by searching inboxes, notes, and past meetings. Important promises and unresolved concerns are easy to miss, and colleagues taking over an account lack the relationship context needed to respond consistently.

Who pays

Client services teams at small agencies and consultancies where several account owners need reliable context before recurring customer conversations.

Business model

Monthly subscription priced by active client portfolio or account-team workspace.

Editorial note

This product is not another inbox. Its useful unit is a reviewable brief assembled for one client conversation, with communication entries serving as evidence rather than becoming a new place to send every message.

Citations and stale-state handling matter more than a polished summary. An account owner must be able to challenge a statement, open its source, correct it, and know when later communication changed the preparation context.

A pilot should test whether reviewed briefs reduce searching and missed commitments. It should not claim that a simple relationship indicator predicts churn or let generated reply text reach a client without human judgment.

Product goal

Who it serves and what it must change

Target user: An account manager preparing for a scheduled client conversation or taking over a relationship from a colleague.
Problem: Relevant messages, decisions, concerns, and promises are scattered, making preparation slow and increasing the chance of an inconsistent response.
Measurable outcome: Given a client with recent communication, an account manager can generate, correct, and mark a brief Ready while tracing every brief item back to a stored timeline entry.

Primary flow

Account manager opens a client and checks recent timeline entries and outstanding commitments.
They select a date range and request a pre-meeting brief.
A worker retrieves only that client's approved entries, calls the model, validates structured output, and saves source references.
The manager corrects the draft, resolves or carries forward commitments, and marks the brief Ready.
If needed, they generate a reply suggestion, edit it, and copy it to their existing communication tool.

Core entity outline

Entities and business rules

Client

The relationship boundary for communication and brief context.

Fields: name, owner_id, relationship_stage, next_meeting_at, created_at
Relations: Has many TimelineEntries, Has many Briefs, Has many Commitments

TimelineEntry

One message, note, decision, or meeting observation available for review.

Fields: client_id, entry_type, occurred_at, author_label, subject, body, source_kind, ingest_status
Relations: Belongs to one Client, May support many BriefItems

Commitment

A promised action with an owner and due state.

Fields: client_id, description, owner_id, due_at, status, source_entry_id
Relations: Belongs to one Client, May originate from one TimelineEntry

Brief

A versioned pre-meeting document reviewed by a human.

Fields: client_id, range_start, range_end, status, summary, changes, concerns, open_commitments, model_label, reviewed_by, ready_at
Relations: Belongs to one Client, Has many BriefItems

BriefItem

A discrete brief statement with provenance and confidence.

Fields: brief_id, section, text, confidence, source_entry_ids
Relations: Belongs to one Brief, References one or more TimelineEntries

Business rules

A generation request may retrieve entries for only one client and the chosen date range.
Every generated factual brief item must reference at least one stored timeline entry; uncited model text is rejected.
Only a human reviewer can move a Draft brief to Ready.
A Ready brief becomes Stale when a newer high-priority message or commitment is added before the meeting.
Relationship indicators are calculated from explicit recency, unresolved commitment, and message-sentiment inputs and must display those inputs; they are not churn predictions.

Architecture and data flow

Components, integrations, and controls

Account workspace

Present client navigation, timelines, commitments, brief review, and reply drafting.

Context API

Authorize client-scoped reads and writes, normalize inbound communication, and schedule generation.

Brief worker

Assemble bounded context, call the LLM, validate structured output, and persist citations and failure state.

PostgreSQL

Store clients, entries, commitments, brief versions, source links, and review actions.

Integrations

LLM API for brief and reply drafts
Transactional email provider for a per-client inbound address and job-failure notifications
Optional Make webhook for explicitly selected communication sources

Data flow

Manual notes or permitted inbound emails are normalized into immutable timeline entries.
A brief request stores its client and date boundary before the job is queued.
The worker sends minimal, client-scoped text to the model and requires a structured response with entry identifiers.
Validated items are saved as Draft; edits create a review trail and Ready locks that version for the meeting.

Failure handling

Mark malformed inbound email as Rejected with a reason instead of adding partial context.
If generation times out or returns invalid citations, keep the previous brief, mark the new job Failed, and allow a retry.
Warn the reviewer when a cited entry was removed or a Ready brief became stale.

Security

Enforce client and workspace scoping in every query and job payload.
Strip email attachments and active HTML from the first release; escape displayed message content.
Keep model and email credentials server-side and document what client text is sent to the model.
Allow administrators to remove a client and derived briefs according to a retention policy.

Rate limits

Allow one active generation job per client and deduplicate identical date-range requests.
Limit inbound email size and messages per sender.
Apply per-workspace model token and request ceilings with visible usage errors.

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Client list, timeline, brief builder, and message assistant
Inbound email parser and manual-entry flow
Queued LLM generation with structured-output validation and citations
Commitment tracking and explainable relationship indicators
Role, isolation, failure-retry, and provenance tests

Acceptance criteria

An authorized user can add two different entry types and see them in correct chronological order.
A generated brief cites only entries from its client and selected period, and every factual item opens its source.
A user can edit a Draft and mark it Ready; later relevant communication visibly marks it Stale.
A reply suggestion is never sent by the application and cannot be produced without selected context.
When the model returns an unknown entry ID, the job fails safely and the last usable brief remains available.

Recommended stack

Enough technology for the first version

Web application

Next.js and Tailwind CSS

Support dense timelines and focused review screens in one responsive application.

Data

PostgreSQL with row-level workspace filters

Model client ownership, immutable entries, citations, brief versions, and commitments relationally.

Jobs

BullMQ and Redis

Run brief generation outside requests and preserve retry and failure states.

OpenAI Responses API with structured output

Produce bounded draft sections whose referenced entry IDs can be validated before display.

Resend inbound and transactional email

Accept a narrow forwarding address and notify owners without synchronizing entire inboxes.

Why this is sufficient

The sensitive boundary is retrieval and provenance, not a complex model stack. Relational client scoping, queued generation, structured outputs, and mandatory review make the generated brief inspectable and recoverable.
