Build a message you can actually prove.
A self-serve AI toolkit that runs the same messaging process Cerys uses with clients. It won’t let you write a tagline before the thinking underneath it holds. Type it out, or just talk.
Free · 60–90 min · Claude or ChatGPT · Type it or talk it“…basically we help small businesses grow faster with better software.”
That’s true of almost every company in your category. Who, specifically, goes looking for this, and what’s the moment that sends them looking?
Fair. Let me think about that properly.
Seven stages. Each one has a gate.
Most founders build backwards: a solution, then a customer, then a message stitched on to justify it. The guide runs the order the right way round, and won’t move on until each stage has earned it.
- 01
Business reality check
Who pays you, for what, and why. Before any product talk.
GateOne sentence, no feature language - 02
Customer and pain
A customer specific enough to be a real person, not a demographic.
GateThree real names that fit - 03
Proof stress-test
Every claim sorted into proven, plausible, or not actually different.
GateOne proven claim, with evidence - 04
Market validation
Checked against what competitors actually say in public today.
GateOne claim survives, uncontested - 05
Message architecture
One umbrella message and three supporting ones, built only from what holds.
GateEvery message has a named proof point - 06
Consistency check
Stress-tested against time, channel and audience before it’s called done.
GateFixed vs. flexible, clearly separated - 07
Gaps and next moves
A one-page architecture, plus exactly what to build or decide next.
GateShort enough to act on this week
Not a tagline. A case.
Type your answers, or think out loud with voice mode or a pasted transcript. Spoken answers get held to the same bar as written ones.
Message architecture
One umbrella message and three supporting ones, each tagged by how solid the evidence behind it is.
Gap assessment
The business decisions still open, and the proof points to build next, in priority order.
A clear next call
Which parts of your pitch are yours, which you borrowed from the category, and when to bring in Cerys.

messaging-toolkit-ai-instructions.mdHow to use it
how-to-use-this-toolkit.mdWorks in any AI tool with project-level instructions. Voice mode, dictation and pasted transcripts all count.
- You’ve hit the same gate twice and can’t get past it.
- You’re finalizing messaging before a raise, launch or major partnership.
- It surfaces a business-model or customer gap bigger than a chat can resolve.
- You want a second, human read before you commit.
