## OwlU

OwlU is a desktop email client with an AI agent layered on top, aimed squarely at people who run their business alone. Instead of juggling Gmail, Outlook, Naver Mail, company webmail, and custom-domain inboxes in separate windows, you connect them all and read them in one place. On top of that unified inbox, an agent summarizes long threads, surfaces what the agent actually did inside the mail UI, and keeps a running context summary so you do not have to re-read a 12-message thread to remember where things stand.

The second half of the product is automation. You describe a workflow in natural language — auto-classify and archive newsletters, pull meeting details out of invitations into a calendar, draft replies as saved drafts, save attachments from specific senders to a local folder, generate a daily processing report, or periodically crawl a web page into a spreadsheet — and the agent runs it. Critically, you choose how much autonomy it gets: fully automatic, semi-automatic, or manual, with approval buttons and a visible run history of total runs, success rate, and failures. A third layer maps the people behind your mail, showing who you correspond with most, which organization an address belongs to, and how the relationship flow has moved over recent months.

The company positions the product around trust signals rather than feature count: it advertises Google CASA Tier 2 certification, a verified Google OAuth app, and a notarized Apple installer, which matters when you are handing an agent OAuth access to work mail. Distribution is a downloadable desktop app for macOS and Windows. Pricing is presented as completely free on the homepage, with no public paid tier listed; as with any free agent product, verify current terms and data-handling details on the site before connecting sensitive accounts.

**Pricing & Plans:** Free. OwlU's homepage states the price is 'Completely free' and there is no public pricing or subscription page, so no paid tier is advertised at this time. Confirm current terms on the official site before connecting work accounts.

- **Unified multi-account inbox:** Connect Gmail, Outlook, Naver Mail, company webmail, and personal-domain addresses and read everything from a single window instead of switching between clients.
- **Human-in-the-loop automation:** Let the agent run workflows fully automatically, semi-automatically, or manually, with approval buttons and a visible log of every action it took.
- **Chat-driven workflows:** Describe an automation in plain language — classify newsletters, extract meeting events, save attachments, send a daily report — and the agent creates and runs it.
- **Thread summaries and context:** Long threads get an AI summary on top of the mail UI plus a running history of decisions, so you can pick up a stalled conversation without re-reading it.
- **Relationship and network view:** See who you talk to most, which organization each person belongs to, and how inbound versus outbound volume has shifted over the last few months.

**Strengths:** Genuinely free per the vendor's own homepage, with no paid tier advertised; Desktop-native app for both macOS and Windows, with a notarized Apple installer; Granular control over automation level plus an auditable run count, success rate, and failure log; Advertises Google CASA Tier 2 certification and a verified Google OAuth app, useful trust signals for handing over mailbox access

**Limitations:** No public pricing or plan page, so it is unclear what terms or limits apply if a paid tier appears later; Requires granting OAuth access to one or more live email accounts; Documentation and help content are thin, so onboarding relies mostly on the product itself

## Shortwave

Shortwave was built by a team of ex-Googlers and is often described as the spiritual successor to Google Inbox. Its starting point is a faster, more organized inbox: tabs and bundles separate what matters from newsletters and promotions, emails convert into a prioritized to-do list, delivery schedules keep interruptions off your clock, and keyboard-first navigation keeps your hands off the mouse. Read receipts and link tracking add the context you normally only get from a sales tool.

The AI layer is where the product has moved furthest. Shortwave's agent works like an assistant inside the mailbox: give it a prompt and it will organize messages, draft replies in your own writing style, check availability and create calendar events, or analyze an entire team's mail and attachments to answer a question. AI filters written in plain English replace traditional rule builders, and autocomplete suggests real links, facts and phrases pulled from your own email history.

Team features address a familiar problem — discussing email in a separate chat app. Shared threads update in real time, teammates can leave private comments on a message, assignments create a clear owner, and shared labels build a common searchable archive. The platform reports CASA Tier 2 compliance, privacy features such as an image proxy and tracking-pixel blocking, and integrations with Slack, Notion, Asana, HubSpot and a sister product, Tasklet, for broader workflow automation. Clients are available for iOS, Android, Mac and Windows.

**Pricing & Plans:** Freemium with a free plan and no credit card required to start. Paid personal and business tiers unlock higher AI usage limits and advanced automation, including the Tasklet workflow product; a free trial is available.

- **Agentic AI assistant:** A conversational agent that organizes your inbox, identifies what matters, drafts replies, writes scheduling emails and runs multi-step workflows from a single prompt.
- **Automatic inbox organization:** Plain-language AI filters and scripts that automatically label, archive, star or sweep messages so you reach inbox zero faster.
- **AI search across email and files:** Ask questions in natural language and search across your own messages — or your whole team's emails and attachments — to get answers rather than links.
- **Real-time team collaboration:** Shared threads, private comments, assigned next steps and shared labels give a team one live view of important conversations.
- **Scheduling and follow-up tools:** Calendar checking, event creation, smart snooze suggestions, delivery schedules, link tracking and follow-up reminders all run inside the inbox.

**Strengths:** Genuinely agentic AI rather than a bolt-on summarize button; Collaboration features remove the need to paste screenshots into Slack; Keyboard-first, fast interface with a modern inbox layout; Broad integration set including Slack, Notion, Asana and HubSpot

**Limitations:** It is a full email client, so migrating means bringing your inbox and workflow with you; Advanced automation lives in paid tiers; Some features depend on connecting external tools like Slack, Notion and HubSpot; The feature set is deep enough that new users need time to learn the automation model
