Rather than asking you to build keyword filters, it applies AI classification to every message that arrives and places it into one of three buckets: Transactional, Promotional or Spam. The result is a messaging inbox where genuine, useful texts rise to the top and marketing blasts fade into the background. Setup is designed to be quick. After installation, Curatio begins categorizing new messages immediately, and its options let you fine-tune the experience. You can choose to see only two-factor authentication codes, divert all promotional messages into a Junk folder, and rely on sub-categorization that splits transactional texts into Carrier, Orders, and Health & Public Services groups. The app is a native, lightweight Utility available on iPhone and iPad and requires iOS 17.2 or later, with Spanish and English interfaces. It is sold as a one-time purchase rather than a subscription, and the developer lists no data collection. Early App Store reviews highlight how it freed up inboxes by removing advertising clutter. **Pricing & Plans:** One-time paid purchase on the Apple App Store (no subscription). No free tier is advertised. - **Automatic SMS categorization:** Every new SMS is analyzed and classified as Transactional, Promotional or Spam with no keyword rules to configure manually. - **Two-factor code focus mode:** Optionally restrict notifications so the only messages that surface are one-time passcodes you actually need. - **Promotional-to-Junk routing:** Route marketing and unwanted texts into a Junk folder so your primary conversation list stays clean. - **Smart transactional grouping:** Transactional texts are further grouped by Carrier, Orders, and Health & Public Services for quick scanning. - **Lightweight and private:** A tiny footprint app that the developer says collects no personal data, keeping filtering on your device. **Strengths:** Works automatically with no keyword rules to build; Optional 2FA-only mode cuts notification noise; One-time purchase rather than a recurring subscription; Developer states the app collects no data **Limitations:** iOS only, so Android users are excluded; Core value depends on how much SMS spam you receive; Some advanced modes (like allowing only 2FA codes) need manual setup; There is no free tier; the app is a one-time purchase [Profile (Markdown)](https://openaitools.app/tool/curatio.md) ## Inbox Zero Inbox Zero is an AI executive assistant layered on top of Gmail and Outlook, built by developer Elie Steinbock (elie2222) and one of the most-starred open-source email projects on GitHub. Once you connect a Google or Microsoft account, it sorts incoming mail into smart categories such as To Reply, Newsletter, Marketing, Calendar, Cold Email and Notification, so you can triage by intent instead of scrolling chronologically. Every message that needs an answer arrives with a pre-written draft based on your past writing and your calendar availability, which you edit and send from the same view. The tool is unusually broad for an email assistant. It blocks cold outreach before it reaches your inbox, shows you which senders you never open and lets you bulk-unsubscribe and archive them in a few clicks, and produces email analytics about who emails you most and what is clogging your inbox. Because it is open source and self-hostable, developers can inspect the code or run it on their own infrastructure — the company is SOC 2 Type 2 compliant and states your data is never used for AI training. Inbox Zero also ships a dedicated email app for Gmail and Outlook across web, macOS, Windows and iPhone, is designed to be used from Slack, Telegram or Microsoft Teams, and offers AI meeting notes and pre-meeting briefings on higher tiers. The core app is free; the AI features are billed as a per-user subscription add-on. **Pricing & Plans:** Freemium with a 7-day free trial on paid tiers. The email app is free; AI plans are billed per user per month (roughly $20 for Starter, $28 for Plus and $40 for Professional on annual billing, with monthly options costing about 20% more). Enterprise pricing with SSO, SCIM and on-premise deployment is available on request. - **Automatic inbox labelling:** Incoming mail is sorted into categories like To Reply, Newsletter, Cold Email, Calendar and Notification as it arrives, using default rules or categories you define yourself. - **Pre-drafted replies:** Emails that need a response get a draft written in your tone and referencing your real calendar availability and CRM context, ready to review and send. - **Cold email blocking and bulk unsubscribe:** Stop cold outreach from ever reaching the inbox, see which newsletters you never read, then unsubscribe and archive them in bulk. - **Email analytics:** Dashboards reveal who emails you most, which senders dominate your inbox and how your habits change over time so you can act on it. - **Open source and self-hostable:** The full codebase is public under an open licence, so teams can audit, extend or self-host it, with SOC 2 Type 2 compliance and no AI training on your data. **Strengths:** Genuinely open source and self-hostable, unlike most AI email assistants; Free core email app plus optional AI add-on keeps entry cost at zero; Combines triage, drafting, unsubscribe, cold-email blocking and analytics in one tool; Works across Slack, Telegram, Teams, web, desktop and mobile **Limitations:** Best experience requires connecting Google or Microsoft account data; Free tier excludes most AI features, which need a paid per-user plan; Advanced tiers quickly get pricey for large teams [Profile (Markdown)](https://openaitools.app/tool/inbox-zero.md) ## Frequently Asked Questions ### How do Curatio and Inbox Zero compare in monthly traffic?
