## Idea

Mail-Ballot Envelope Check for California
California voters scan their mail-ballot return envelope before sending it to spot signature and other rejection risks, then receive cure deadlines if official tracking shows a problem.

## Product concept

For California voters completing a mail ballot, the most common mistakes are often not in the choices themselves, but in the signature, date, envelope assembly, and county procedures. Before mailing, users scan the return envelope and accompanying materials with their phone. The app checks only exterior information locally on the device; it never reads or uploads ballot content. The screen checks each item against the official requirements for the user’s county, including signature placement, date entry, inner and outer envelopes, and any required declaration. When it finds a risk, it marks the spot directly—for example, a missing signature, an invalid date format, or an incorrectly sealed envelope—and explains how to fix it. Once the scan passes, users can save the official tracking number and mailing date. After mailing, the product periodically checks official tracking status. If a signature review, missing material, or other issue appears, it shows the county’s cure deadline, official website, and documents to prepare. The first version covers only exterior mail-ballot verification and status follow-up in California. It does not replace election officials or evaluate any ballot content.

## Why now (backed by facts)

On July 23, the Associated Press reported that nearly 150,000 mail ballots were rejected in California’s June primary; searches for the term then exceeded 20,000, up 900%, before interest had already fallen by July 24. The coverage has brought rejection causes into public discussion, making voters more likely to check signatures, dates, and deadlines before mailing.

## Direction (model inference, not independently verified)

Target user: The core user is a California voter who votes by mail and worries about the paperwork just before sealing the envelope. First-time mail voters, people with limited vision, and voters less comfortable in English may find county instructions especially hard to check quickly. Anxiety peaks just before mailing or after an issue notification arrives. At that point, they need to see the specific omission, deadline, and official link—not reread an entire guide.

Minimal entry point: The camera flow permits photos only of the outside of the return envelope and accompanying instructions; scans are deleted after use. On iOS, Vision’s on-device text recognition and bounding boxes can locate signature, date, and declaration areas. County requirements become auditable, versioned rule packs rather than being buried in an unexplainable model. Automated checks assess only whether fields are filled in, correctly placed, and legible. Envelope sealing and inner-versus-outer envelope checks use guided photos followed by user confirmation. For status follow-up, the product can parse BallotTrax emails forwarded by the user while retaining links to the official portal. Until a formal API is available, it will not scrape login pages or retain voter login credentials.

The strongest case against: The biggest risks are false positives and false negatives. Mistaking a shadow for a missing signature could lead a voter to reopen a sealed envelope. Missing a real issue creates false reassurance. A signature being present does not mean it will match the voter-registration record; election officials still make that determination. County layouts, languages, and cure links can change, so rule packs must be reviewed for each election. Official tracking offers portals and notifications, but has not confirmed a public interface for consumer apps. Status automation must therefore rely on forwarded emails or authorized partnerships. If county-level review and a human fallback are not possible, the product should not promise that a scan has passed.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Create county-specific practical pages such as “What to do if you forgot to sign” and “What to do if your ballot is rejected,” citing only official procedures. During the ballot-mailing period, place localized check pages in voter guides from universities, civic organizations, and community media. Keep shareable links to county official portals on issue screens so family members or volunteers can help. Acquisition should focus on search and partner distribution rather than ongoing retention.

## Competitors & gaps (model inference)

- Where’s My Ballot? (BallotTrax): This is the closest adjacent product and the official default entry point. Powered by BallotTrax, it offers email, text, or voice notifications in every California county. Notifications cover ballot mailing, county receipt, acceptance status, and instructions for resolving issues. It already addresses most post-mailing anxiety, so voters have little reason to install another app that only sends similar alerts. Its public feature descriptions focus on status tracking and do not offer visual verification of the return envelope before mailing. The opening is the moment before drop-off: identify the signature and date fields, and turn county requirements into an actionable check. The product should still treat official tracking as the source of truth. Its real differentiation is preventing mistakes, not replicating notifications.
- County election office instructions, cure forms, and hotlines: County election-office instructions, websites, and cure forms are the final authority on procedural requirements. They provide county-specific rules, cure channels, and contact information, with greater authority than any third-party app. Their limitation is not a lack of facts, but that voters must still find, read, and compare the materials themselves just before sealing the envelope. Paper instructions cannot point to a missing field on the envelope in front of the voter. Websites also usually require voters to identify the issue first. The product can map official requirements to the specific layout and use highlights to complete the check. When recognition is uncertain, it should show the original text and the county link directly. The tradeoff is that templates, languages, and links must be revalidated for every election. Without a county review process, it should not claim to have completed a compliance determination.

## How it makes money (model inference)

Free for voters; charge universities, unions, and community organizations per election cycle for white-label deployment and county-rule maintenance.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
