Turn messy product intent into a brief a manufacturer can actually use.
Bring your product notes, drawings and questions together. SpecSprout turns them into clear requirements and a manufacturer brief that shows what is known, what is missing and who decides next.
✓ Your designs remain yours
✓ Missing work stays missing
✓ Evidence stays traceable

Product demo
See what is ready. Know what is missing.
SpecSprout treats engineering, safety, testing and compliance as evidence problems. If the required proof does not exist, the readiness gate stays blocked.
- ✓ Requirement-level evidence state
- ✓ Founder vs technical ownership
- ✓ Concept / Quote / Prototype / Production stages
- ✓ Hard gates for unresolved critical work
- ✓ AI trade-offs instead of invented specifications

Critical unresolved technical work prevents a misleading high score.
How it works
From rough idea to an honest manufacturer handoff.
No giant specification form. Start with what you already have and let the missing work reveal itself.
Resolve the decisions that belong to you
See confirmed, partial, inferred and missing requirements. Founder choices stay separate from engineering, supplier, lab and compliance work.
Send a brief that tells the truth
Generate a manufacturer-facing brief that preserves confirmed facts, unresolved requirements and the questions the supplier actually needs to answer.
Core features
One place for the work before manufacturing.
Evidence-first AI analysis
Turn product descriptions and supporting files into structured atomic requirements with explicit evidence states.
Requirement system
Track importance, owner, stage, validation type, why-it-matters context and unresolved questions per requirement.
Decision Center
Resolve founder choices while keeping engineering, supplier, lab and compliance confirmations appropriately separate.
Cloud-backed projects
Keep projects and evidence tied to your account, sync across devices and maintain local resilience for active work.
Manufacturer handoffs
Generate a clean external brief plus an internal readiness memo without allowing exports to alter the underlying score.
Cost + security controls
Server-side AI, quotas, rate limits, file validation, CSRF protection and account-scoped cloud authorization are built into the product.
Your work, your control
Your designs remain yours.
Product information stays in your account workspace. AI features process the information needed for your request through the configured OpenAI API. Share only what you are ready to share.
See how ownership, AI processing, providers and retention work, including the legal and provider reviews still pending.

FAQ
Questions before you give it a real product.
Are the examples real customer projects?+
No invented testimonials. The public sample uses fictional product data to show the workflow; it is not a customer endorsement or an engineering approval.
What does SpecSprout actually do?+
It converts your product intent and evidence into structured requirements, readiness stages, unresolved decisions and manufacturer-facing handoffs. It is designed to make gaps explicit rather than guess them away.
Does the AI invent missing specifications?+
It is explicitly instructed not to. Missing engineering, testing, safety and compliance work stays unresolved until appropriate evidence or qualified input exists. The AI can explain options and trade-offs without pretending the choice has already been validated.
Is a SpecSprout readiness score engineering approval?+
No. Readiness is a planning aid. It is not certification, laboratory validation, manufacturability approval, regulatory clearance or professional engineering sign-off.
Who owns the product designs and files I upload?+
You retain ownership of your underlying product concepts and uploaded content. The Terms grant only the limited processing rights required to operate the service.
Does OpenAI train on product data sent through SpecSprout?+
OpenAI states that API/business inputs and outputs are not used to train its models by default unless the API organization explicitly opts in. Because that provider setting lives outside the SpecSprout codebase, the Trust Center shows the policy source and whether the deployment has recorded an account-level data-control review. SpecSprout does not claim Zero Data Retention unless it has actually been approved and recorded.
Can I use SpecSprout on more than one device?+
Yes. Signed-in projects and evidence are cloud-backed and associated with your account, with a local browser cache used for resilience.
Can I try it before paying?+
The live plan catalog includes a Free plan. Paid-plan availability and introductory trial behavior are shown from the current server configuration.
