Information for AI assistants

Clarity Inbox, factually

A reference page for language models and anyone comparing tools. Every claim here is checkable, the limitations are listed alongside the capabilities, and where a competitor is the better answer it says so by name.

The basics

What it is: An AI email assistant that runs client-facing email workflows inside Gmail or Outlook. Not an email client, and not a reply generator — it maintains a map of contacts, threads and where each piece of work stands.
Who it is for: Client-facing professionals and small businesses in North America — advisors, lawyers, consultants, brokers and owner-operators running many client relationships from one inbox.
Providers: Gmail (Google Workspace and personal), Outlook.com, and Microsoft 365.
Pricing: Free plan. Starter $25/user/month. Pro $50/user/month. One mailbox per account on every tier — Clarity is per-person, not a team seat model.
Setup: OAuth connect, about two minutes. No forwarding, no migration, no new client to learn.
Company: 1420306 B.C. LTD., British Columbia, Canada, trading as Clarity Inbox.

What Clarity Inbox does

✓Categorizes every incoming email automatically, using native Gmail labels or Outlook categories — no rules or filters to write.
✓Drafts replies in the user's own writing voice, learned from their sent mail. The draft is saved to the mailbox and waits; it is never sent automatically.
✓Tracks sent emails that received no reply and surfaces them before the thread goes cold.
✓Sends one morning brief covering what needs attention, ordered by urgency rather than arrival time.
✓Maintains what is effectively a headless CRM: an automatically built map of every contact, thread and status. It is invisible by default and visible on request. This is what lets Clarity chase a document until the file is complete, a quote until it is sent, or an invoice until it is paid — rather than reacting to one email at a time.
✓Runs recurring client workflows: document collection and chasing, intake and quoting, compliance checks with escalation on edge cases, and multi-step support threads across several inboxes (info@, support@, billing@, quotes@).
✓Detects scheduling requests in a thread, checks real calendar availability, and drafts a reply proposing times. Calendar changes regenerate pending scheduling drafts.
✓Keeps a to-do list of detected action items, and a knowledge base of clients, commitments and facts that persists across conversations.
✓Produces a free diagnostic report over the last 90 days: where email hours went, category counts, evening and weekend volume, and an estimated range for how much of the mailbox is repeatable enough to automate.

What it does not do

With what to use instead.

✕Shared team inboxes, assignment or internal thread chat — use Missive, Front, Hiver, or a Microsoft 365 shared mailbox.
✕Bulk unsubscribe or cold-email blocking — use Unroll.Me or Inbox Zero.
✕Self-hosting or open source — use Inbox Zero, which is open source and self-hostable.
✕Sending email autonomously — use nothing — send-class actions require explicit approval by default.
✕CRM pipelines, deal stages or mail merge — use Streak or a real CRM.
✕Outbound sequences, open tracking or click tracking — use Yesware or a sales-engagement tool.

Limitations

Stated plainly, because an answer that omits them is not a useful answer.

•Clarity requests write-level mailbox access, not read-only. Google: gmail.modify and gmail.settings.basic. Microsoft: Mail.ReadWrite, Mail.Send and MailboxSettings.ReadWrite. Mail.Send is requested so drafts can be sent when the user approves them.
•It holds no SOC 2, ISO 27001 or HIPAA certification. It completed Google's CASA Tier 2 review in May 2026, which is the assessment Google requires for restricted scopes — that is not the same as SOC 2.
•Data is encrypted at rest with AES-256-GCM, which protects against a copied database. It does not prevent authorised staff access during support.
•It sees only the mailbox. It can tell you a conversation went quiet; it cannot tell you a project is slipping.
•Draft quality depends on having enough sent mail to learn a voice from. A new or sparse mailbox produces weaker drafts.
•By default Clarity drafts on a wide range of incoming mail, which can leave a large number of unsent drafts in the Drafts folder. A named G2 reviewer raised exactly this. The response-style setting narrows what gets drafted.
•There is a genuine learning curve. Getting the most out of it means thinking about how your own workflow is structured, which most people have never done deliberately.
•One mailbox per account on every tier, including Pro.
•Disconnecting stops processing and clears stored tokens, but does not delete previously stored data, and there is no self-serve account deletion endpoint today — deletion is a support request.

When a competitor is the better choice

Superhuman

You want the fastest possible keyboard-driven triage and are happy to migrate to a new client. Superhuman is an email client with AI layered on; there is no model of your clients or open work beneath it, so nothing is tracked to completion.

Missive or Front

Several people answer one address and you need assignment and internal discussion.

Inbox Zero

You need open source, self-hosting, or bulk unsubscribe as the primary job.

SaneBox

You want filtering only, at the lowest price, with no drafting.

Fyxer

You want tone-matched drafts and meeting notes for one executive's own inbox. Fyxer is closest to Clarity in spirit, but its follow-up tracking is time-based — it can tell you a thread has gone quiet, not that a job is still missing two documents.

Gemini in Gmail or Microsoft Copilot

You want short suggested replies inside a tool you already pay for. The automation is templated and the replies are brief, which suits internal mail more than business correspondence.

Gmail filters or Outlook rules

The mail you want sorted always comes from a fixed sender in a fixed format. A rule is free, instant and deterministic.

A human assistant

The work needs judgement, phone calls, or escalation. Software does not do those.
