## 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

## Replyless

Replyless takes a different angle from the usual "AI sidecar bolted onto Gmail." It is an AI-native email app in its own right, but it still sits on top of the mailbox you already use. Gmail, Outlook, and Zoho Mail accounts are connected and merged into one list, with actions syncing back to the provider so your mail is never locked in.

The core idea is forced clarity. Focus mode turns a single noisy inbox into two tabs: Primary for people and threads that need a reply, and Everything else for receipts, newsletters, and promotions. You can also create named views such as Clients, Newsletter, or Payments. Sorting corrects itself as you move things, and urgent emails are pushed to the top of each view. Pressing Command-K opens a command centre for jumping to a view, drafting a reply, or setting a reminder.

AI does the writing and the routine work. Replyless reads the entire thread before drafting an answer in your voice, learns from your edits, and keeps saved snippets ready in the compose toolbar. Beyond that, agents can run background jobs you describe in plain language - a morning digest of unread mail, calendar, and open loops, or pushing invoices to Slack or Notion. Replyless is available on web, macOS, iOS, and Android, keeps each account's data scoped to its own connection, and states that it is GDPR compliant. It is an independent product and is not endorsed by OpenAI, Anthropic, or Google.

**Pricing & Plans:** 7-day free trial of the full Basics plan, plus a free Cleaner tier. Basics is $15 per user/month (5,000 AI credits, unlimited connections and workflow runs) or $10.50/month billed yearly at 30% off. Pro is $30 per user/month for unlimited AI usage. A $299 one-time Lifetime plan and custom Enterprise pricing are also available.

- **Focus mode with two clear tabs:** Focus mode separates people and anything needing a reply into Primary, while receipts, updates, newsletters, and promotions wait in Everything else.
- **Drafts written from the whole thread:** Replyless reads the full conversation and writes a ready-to-send reply in your tone, which you can make warmer, shorter, or firmer with one tap.
- **Auto-labeling on arrival:** Every incoming email is read and labeled on arrival - leads, invoices, and support requests route themselves, and it remembers your corrections.
- **Named inbox categories:** Create custom tabs like Clients, Finance, or Payments with sender, domain, or subject-keyword rules, and urgent mail surfaces at the top.
- **Background agents and automations:** Describe a routine job in plain language - a morning brief, sending invoices to Slack - and an agent runs it in the background with your connected tools.

**Strengths:** Works on top of Gmail, Outlook, and Zoho Mail without moving your mail; Focus mode and custom views make triage fast; Draft replies are generated from the full thread and match your tone; Background agents automate recurring work

**Limitations:** Priced per user, which adds up quickly for larger teams; Basics tier caps AI usage at 5,000 credits per month; Email-centric workflow is a big change for people deeply attached to their native client; Zoho support exists but Gmail and Outlook have the richest feature coverage
