Read-Only Inbox Triage
A web service that connects a Google or Microsoft mailbox using only gmail.readonly or Mail.Read, so the token cannot send, move or delete mail even if the code has a bug.
摘要
简报自行申报
Read-only AI email triage: connects Gmail/Outlook with read-only scopes, ranks every message and sends a morning digest of the ~5 that need you, never sending, archiving or deleting. Demand is real but thin (6 HN users asked, 1 would pay, per Ravoid) while the category is hot (Fyxer $1M to $17M run-rate in 8 months, self-reported).…

POS 64/10093% modeled margin, but Google CASA (annual $499-$5,400) and Gmail's AI Inbox (paid Workspace, Oct 15 2026) cap the upside.
描述
A web service that connects a Google or Microsoft mailbox using only gmail.readonly or Mail.Read, so the token cannot send, move or delete mail even if the code has a bug. Messages are classified in batches by a small LLM (needs reply, task, read later, receipt, promo) with a priority, a one-line reason, any deadline and who owes whom.…
阅读其余部分
Only labels and reasons are stored, never bodies. Users get a morning digest of what needs them, a backlog digest after time away, and a stalled-threads list; corrections become per-sender rules. Trust is the product: zero write actions, public data-flow write-up and a delete-my-data button.
目标客户
Independent consultant or boutique-firm partner with 150-400 emails/day across work and client mailboxes, handling confidential data, refuses write-scope AI, pays for own tools ($12-$24/mo).
痛点
When I open my inbox each morning or return from time away, I want to see the few messages that need me, hidden deadlines and what was decided without me, so I can act in minutes without giving any tool power to change or send my mail.
为何是这个分数
分数较低的原因： Feasibility HIGH: gmail.readonly is a restricted scope requiring Google verification plus annual third-party CASA ($499-$5,400/yr), several weeks, Gmail limited to test users until cleared.
护城河
Weak to moderate: provable read-only OAuth posture, no bodies at rest, CASA Letter of Validation, per-sender learned rules, Portuguese/LatAm-first localization. Native Gemini/Copilot can erode features; moat is independent, auditable positioning.

Ask HN 47317429 (2 pts, 4 comments) explicitly wants zero write permissions; Show HN 41943931 (12 pts) drew 'I would never trust it with full access'.…

全部风险
Feasibility HIGH: gmail.readonly is a restricted scope requiring Google verification plus annual third-party CASA ($499-$5,400/yr), several weeks, Gmail limited to test users until cleared. Value: thin demand evidence and Gmail AI Inbox shipping to-dos/deadlines natively. Viability: platform bundling and low virality. Usability: low risk.
