Newsletter Voice
Ask Seba to learn how your newsletter sounds and it returns a reusable voice profile — opening formula, section flow, data rules and signoff — from your past issues or a tuned archetype. You paste it back when you draft. Billed per run.
A reusable voice profile, not a one-off rewrite
Learns from your real issues
Paste 2-3 past newsletters and Seba finds the patterns that repeat across them — not one-offs — so the profile reflects how you actually write.
Or starts from an archetype
No back issues yet? Pick one of six newsletter archetypes and Seba tunes its defaults to your voice, flagging to revisit after about five issues.
Sits on top of your general voice
It adds newsletter-specific rules only — opening, sections, data philosophy, formatting, signoff — without duplicating your general voice profile.
Just paste your issues
No tool to configure. Drop your past newsletters in Telegram and the profile comes back as a file you keep, billed per run.
What the voice profile captures
The structure an editor would reverse-engineer from your archive, in one pass.
- Opening formula — what the first 3 sentences do, length before the first break, credibility move, value promise
- Section flow — 5-8 sections, what each one does and its rough length
- Data and evidence — numbers per issue, source attribution, example-to-abstraction ratio
- Formatting rules — headers, lists, bold / italic and visual markers you use vs avoid
- Closing and signoff — forward-looking vs summary, signoff only if consistent across issues
- Length target — your word-count range, with a separate target for long guides
- What this newsletter never does — 3-5 behaviours pulled from your absence patterns
- Archetype defaults — when built from a template, tuned to your voice and flagged for revisit

Frequently asked questions
What does Seba deliver?+
A reusable newsletter voice profile — an 800-1,200 word file covering opening formula, section flow, data philosophy, formatting, closing, length and what your newsletter never does.
Does Seba write or send my newsletter?+
No. This skill builds the voice profile only. You keep the file and paste it back later when you want to draft an issue — Seba never sends or schedules anything to your subscribers.
Do I need past issues?+
It works best with 2-3, where Seba learns patterns that repeat across them. If you have none, pick one of six archetypes and Seba tunes its defaults to your voice instead.
Is this the same as my general voice setup?+
No. Newsletter voice sits on top of your general voice and adds email-specific rules only. If a general voice profile is in the chat, Seba builds on it; if not, a quick sketch works.
What format is the profile?+
A plain code-block file you can keep and reuse. It is structured by section so you can edit any part and paste it straight back into a future drafting session.
How much does it cost?+
You spend credits per run, and Seba shows the exact cost before it starts. Start free with welcome credits; credits never expire.
