## Ghostwrite

Ghostwrite targets the part of email nobody enjoys: staring at an empty compose window while trying to phrase a request, an apology, or an awkward ask. Instead of building the message from scratch, you hand over just the essentials — something like "ask the landlord to send a plumber quickly" — and the assistant drafts full prose you can polish.

The product leans on a friendly in-app helper persona, Inky, who is described as learning your style over time so drafts sound more like you the more you use the tool. The workflow is deliberately a three-step loop: give the details, receive the draft, then approve before sending. Nothing is sent on your behalf without your consent, which keeps a human in the loop on tone and factual accuracy.

Ghostwrite is aimed at people who find professional correspondence draining — job seekers, freelancers, people who dislike networking, and anyone dealing with high-stakes or socially awkward messages. It runs in the browser as a web app, so there is nothing to install, and it offers a free entry point with paid tiers for heavier use.

Note: Ghostwrite is an independent product and is not affiliated with, endorsed by, or produced by OpenAI or any other model vendor whose technology it may use.

**Pricing & Plans:** Freemium. A free entry point is offered through the Get Started flow, with paid subscription tiers for more usage. Specific tier limits are not published on the homepage, so check the site for current numbers.

- **Brief-to-draft generation:** Enter only the core facts of what you want to communicate and receive a complete, coherent email draft in return.
- **Personalised tone over time:** The assistant is designed to learn your phrasing and preferences so later drafts read closer to your natural voice.
- **Approve-before-send workflow:** Drafts are never dispatched automatically — you review, edit and add personal touches, then send the message yourself.
- **Built for difficult messages:** Handles the awkward end of correspondence: big asks, negotiations, apologies, cold outreach and follow-ups.
- **Browser-based access:** Runs entirely in the web browser with no installation or desktop client required.

**Strengths:** Turns a one-line brief into a full draft, cutting the blank-page problem; Human approval step means you keep control of tone and accuracy; Drafts reportedly adapt to your style as you keep using it; Simple, low-friction web interface with nothing to install

**Limitations:** No public pricing table on the homepage, so costs must be checked in-app; Output still needs a read-through for specifics, dates and names; Only covers email writing — no inbox management, scheduling or CRM features

## 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
