One AI gives you one voice. Your competitors are using the same one.
Deepest sends your brief to several top AI models at once and shows you exactly where they disagree. Different models argue for different positioning, write in genuinely different registers, and catch each other's lazy claims. In work that lives or dies on differentiation, the disagreement is the point.

Watch three models argue the positioning
One budgeting app, three top models, three different launch strategies. The split is the strategy meeting you did not have to schedule.
Simulated demo for illustration. Actual responses are more detailed and personalized.
Why one AI is not enough in marketing
A single chatbot gives you one voice, one bias, and one strategist who never pushes back. Your audience has already learned to scroll past it.
Every ChatGPT ad sounds like every ChatGPT ad
A single model has a house style: the same rhythms, the same openers, the same rule-of-three punchlines. Because most teams prompt the same one or two chatbots, single-model copy across the industry converges on the same AI-flavored median. Several models writing from different biases give you genuinely different registers, which is the raw material taste actually needs.
One strategist who always agrees with you
Ask one model whether your positioning works and it will find reasons it does; a brief written with conviction gets echoed back with conviction. Run the same positioning past three models and the flattery cancels out. The objection two of them raise independently is the one your market will raise with budget on the line.
You cannot test three rewordings of one idea
A/B tests need variants that differ in concept, not phrasing. One model asked for three options gives you the same strategy in three outfits, and the winning variant tells you nothing. Models with different biases place different bets: pain against outcome against enemy, not synonym against synonym. That is a test worth paying traffic for.
How marketers use Deepest
Three ways to combine the models, mapped to how marketing work actually gets made.
Compare · where the models agree and disagree
Compare: three creative directions per brief
Ask once and every model answers side by side, with an automatic breakdown of where they agree and where they split. Use it on positioning calls, campaign concepts, and any headline you are about to put budget behind. Agreement across models means the claim is safe, and possibly too safe to differentiate. The disagreement is a map of the real strategic options and what each one costs.

Compare
Three positions, three different metrics. The split is the strategy decision.
Debate · models argue and converge
Debate: the pitch meeting before the pitch meeting
Debate makes the models argue against each other and converge over rounds. Feed it your positioning and watch what survives contact: the objections that emerge preview what your skeptical CMO, your sales team, and your market will say, in that order. The claim left standing after two rounds is the one worth putting money behind.

Synthesis · one combined best answer
Synthesis: one draft from the strongest lines
Once the direction is set, you want the best single execution, not three more options. Synthesis has the models write independently, then combines the sharpest hooks and cleanest arguments into one draft. Launch emails, landing pages, and campaign copy arrive with each model's best lines and nobody's tics.

What marketing work looks like with a model panel
Four places marketers put Deepest to work on day one. Each prompt is copyable as written.
Positioning stress-tests
Run a positioning statement past several models and get independent strategic reads. Each model attacks from a different angle; the disagreement report shows which tradeoff you are actually choosing between.
Try this prompt
We are repositioning our B2B analytics tool from 'dashboards for your data' to 'decisions without meetings.' Argue for and against the move, list the three strongest customer objections, and say what evidence would settle each one.
Copy variants that actually differ
Get ad and landing page variants that place different strategic bets instead of rewording one idea three times. Test concepts against each other, not synonyms.
Try this prompt
Write three launch headlines for [product], each from a different strategy: one leading with the pain, one with the outcome, one against the category's default way of doing things. No overlapping phrasing between them.
Audience and objection analysis
Have the models independently profile who buys, who churns, and what unspoken objection sits behind the survey answer. Where their reads differ is where your assumptions need real research.
Try this prompt
Our churn survey's top answer is 'it stopped feeling useful.' Profile the segment most likely behind that answer, name the real objection underneath it, and draft the retention message that answers it: [paste product description]
Competitive messaging teardowns
Feed in competitor copy and get independent teardowns of the territory each brand claims. Three models mapping the same landscape surface the unclaimed position a single read would miss.

Here are the homepage headlines and subheads of our three main competitors: [paste]. Map the positioning territory each one claims, identify the space nobody owns, and draft the claim we should plant there.

Confidentiality
Built for campaigns that are not public yet
Conversations are encrypted in transit and at rest, are never used to train models, and you can export or permanently delete everything at any time. Prompts go to model providers through enterprise APIs, not consumer chatbots. Unannounced launches, pricing changes, and campaign strategy stay yours; nothing you paste becomes training data or someone else's autocomplete.
Questions marketers ask
Work in a different field? Deepest works the same way for writers, product managers, consultants, and every other profession.
