What to show: the right-hand “Thought Stack” panel — 6–8 stacked research cards, each with a thin amber outline and a small lightbulb icon. Top card “Thought 1: Your Product Idea,” with “Thought 2: Objective + Scope” expanded to reveal a “Decision we need to make” heading and a couple of bullets, the rest collapsed below.

What you get

Eight cards. One organized brief.

The agent auto-creates and fills in all eight Thought cards with you — not a chat you’ll never re-read, but a workspace you can edit, revisit and export.

01

Your Product Idea

Your North Star — who it’s for, your core differentiator, your constraints.

02

Objective + Scope

The decision you’re making, what’s in and out of scope, and what success looks like.

03

Competitor List

A researched table of rivals with links, pricing and who they sell to.

04

Feature Matrix

Side-by-side features vs. you — gaps and strengths surfaced at a glance.

05

Positioning Swipe File

Competitor taglines and claims, with patterns spotted (“3 of 5 say AI-powered”).

06

Insights

The synthesis — patterns, real differentiators, and the gaps worth owning.

07

Decisions & Next Steps

A concrete positioning statement plus a short, doable action plan.

08

Evidence Locker

A running, cited list of every source the agent used along the way.

How it works

Four steps. The agent does the heavy lifting.

It’s a guided, step-by-step workflow — one decision at a time, from “I don’t know my market” to a brief you can act on.

1

Tell it your idea

In plain words: who it’s for and what makes you different. No jargon, no blank page.

AI does the digging

The agent searches the web — competitor sites, pricing, reviews, funding — so you don’t have to.

Agent fills your workspace

Eight structured cards get drafted for you. You steer and edit; it never rushes ahead.

A Community built and supported project.

  • A bootstrap project, built in public.
  • You pay pass-through LLM usage fees (usually pennies) plus a small management fee to cover hosting and ongoing development.
  • We ship fast and listen closely — join us on Reddit to influence the roadmap.
Simple pricing

A brief costs less than a coffee.

No subscription, no seats. You only pay for what the agent actually does — and we’ve made it almost embarrassingly cheap.

Typical brief
<$5

Most founders finish a complete competitive brief for under $5. Some come in closer to $2.

Pay-as-you-go · no subscription

Start with a $10 deposit. That’s usually two briefs.

Top up your account once, then run as many briefs as the balance covers. We’ll show your remaining balance as you go — and we’ll never charge you a subscription.

  • $$10 gets you startedCovers your first brief with change left over.
  • ✓Only pay for what you useYour balance only ticks down when the agent actually works for you.
  • ↻Re-open anytime, freeYour brief stays in your workspace — no extra charge to view or edit it later.
How it worksThe AI charges by the token — a small unit it uses to read and write. You pay the model’s exact rate plus a small management fee, which is all ThoughtStack keeps. That’s the whole pricing model.

Why founders use it

Less staring at a blank doc. More deciding.

The agent does the research

It proactively searches competitor sites, pricing pages, reviews and funding news — and drafts every card. You’re never on a blank page.

Built for first-time founders

Plain language, no jargon. “Who you’re selling to,” not “ICP.” It explains as it goes.

A workspace, not a chat

You finish with an organized brief you can edit, revisit and export — not a transcript you’ll never re-read.

Everything is cited

The Evidence Locker keeps a clean, linked list of every source as it works, so you can trust — and double-check — each claim.

Guided, one step at a time

It walks you through a single decision at a time and won’t rush ahead. You always know where you are.

Eight cards, structured for you

From your North Star to Decisions & Next Steps — the brief is organized the way founders actually think.

Questions, answered

The stuff first-time founders ask.

Nope. That’s the point. The agent explains each step in plain language and builds the matrix for you — you just confirm and tweak. No jargon, no prior experience needed.
The agent searches the live web — competitor sites, pricing pages, G2 and Capterra reviews, and funding news. Every fact it adds is linked in your Evidence Locker so you can check the source yourself.
It’s built to stick to what it can cite. Claims are tied to sources in the Evidence Locker, and you steer the whole way — so you can verify anything before you rely on it.
Always. It’s your workspace, not a locked report. Edit any card, add your own notes, remove what’s off-base, and revisit it whenever the market shifts.
A focused first pass takes minutes, not a weekend. You can go deeper card by card whenever you want — the brief is reusable, so it grows with you.
Yes — you can start a brief without signing up and see real output before committing to anything.
