What real task does your product handle with GPT-6 Astra?
Maker
Lastbox helps people reduce unwanted US postal mail. It gives their AI a permission-aware workflow for USPS Informed Delivery setup, reviewing accessible mail evidence, choosing appropriate opt-outs, and keeping an honest record. GPT-6 Astra in Codex helped build and refine this version: readable prompt delivery, ChatGPT/Claude handoffs, focused setup questions, and recovery when browser, email, or scheduled access is unavailable. Lastbox currently distributes instructions; it does not run a hosted Astra agent or access mail itself. Users choose their AI provider and approve its connections and actions.

Hi Product Hunt — Phil here from Pixel Potion.
I want less paper printed, delivered, and thrown away. Lastbox gives the AI you already use a practical plan for reducing unwanted US postal mail.
Choose the help you want, copy the free prompt, and open it in ChatGPT or Claude. It guides USPS Informed Delivery setup, reviews the mail evidence your AI can access, and helps work through appropriate opt-outs. You decide whether to allow browser use, mail-related email, submissions, and weekly follow-ups.
A big part of the build was handling the awkward parts: an AI chat without browser tools, the wrong email account, or a task that can’t actually run next week. The prompt asks your AI to explain those gaps and help with setup before falling back to manual work.
I used GPT-6 Astra in Codex to refine that setup flow, build the prompt handoff, and work through permissions and recovery cases. Lastbox predates this challenge; Astra helped advance this version.
Lastbox provides the instructions; your AI provider handles the access you grant. Informed Delivery requires an eligible address, and opt-out services have their own coverage, costs, and processing times. There’s no promise that every piece stops.
The larger mission is simple: “Junk mail shouldn’t have a future.” We’re rethinking the mailbox. More soon.
I’d love to hear where the workflow is clear, where access gets in the way, and which kinds of unwanted mail are hardest to handle.
