All 5 alternatives, ranked

1
Gemini Free tier
Google's assistant with Deep Research reports, Gmail/Docs/Drive integration and YouTube video understanding.

+ Deep Research produces long cited reports from dozens of sources, and it reads your Gmail, Drive and Calendar directly when you allow it.
− Quality swings between Flash and Pro models, and it refuses or hedges on some topics more than competitors.

2
Grammarly Free tier
A writing assistant that checks grammar, tone and clarity everywhere you type and rewrites or drafts text on request.

+ Works in nearly every text field on every platform, so corrections and tone suggestions follow you into Gmail, Slack and Word.
− Suggestions can flatten a distinctive voice and the premium nag prompts in the free tier are constant.

Microsoft Copilot Free tier
Microsoft's assistant, free on the web and Windows, and embedded in Word, Excel, PowerPoint, Outlook and Teams with Microsoft 365 Copilot.

+ Works inside the Office apps you already use, drafting Outlook replies, summarizing Teams meetings and turning Word docs into PowerPoint decks.
− Results inside Excel and PowerPoint are often shallow compared with the standalone chat, which makes the $30 business seat hard to justify.

4
Shortwave Free tier
An AI-first Gmail client whose assistant searches, summarizes, drafts and organizes your email in natural language.

+ Ask questions across your entire mailbox and have the assistant draft replies grounded in past threads.
− Gmail-only, and the bundled-threads inbox model takes getting used to.

Lavender Free tier
A sales email coach that scores your draft in Gmail or Outlook and suggests edits to raise reply rates.

+ The real-time score and prospect research panel sit next to the compose box and make cold emails shorter and more specific.
− Scores reward a formulaic short style, and it is sales-specific rather than a general email assistant.
