What is Fyxer AI?

Fyxer AI is an AI‑powered assistant that connects to your Gmail or Outlook inbox to sort emails, filter out spam and draft replies that match your tone. It learns your writing style, join meetings to take notes and prepare follow‑up messages, and can schedule meetings across teams and time zones.

Why look for Fyxer AI alternatives?

Fyxer AI presents several limitations that could lead users to consider alternatives. It often produces replies that lack personalization and may not reflect your tone of voice. Additionally, issues reported by users regarding its reliability further encourage the exploration of other options.

1. Untyped

Untyped is an AI assistant that connects to Gmail or Outlook and generates draft replies for incoming emails. It analyzes your past emails to learn your writing style and creates responses that match your tone. It prepares drafts automatically when new messages arrive, allowing you to review and send them quickly. Untyped also supports inbox organization through labeling, categorization, and workflow features.

Pros

  • 5 minute setup to work directly in Gmail & Outlook with simple pricing at 15 usd per month.
  • Trains itself automatically on your entire email history and keeps learning afterwards.
  • Scores exceptional on drafting replies exactly in your tone of voice.
  • Very flexible to manually add data and with possibilities to connect external datasources.

Cons

  • No possibility to transcribe meetings.
  • Is not compatible with IMAP so it can only be of use when you use either Gmail or Outlook / Microsoft 365.

When to choose Untyped over Fyxer AI?

Choose Untyped when you want a system that integrates directly with your email history for personalized replies. Unlike Fyxer AI, Untyped learns continuously from your communications, ensuring that responses are tailored to your style. This makes it a preferable option for users who prioritize accuracy and customization.

2. Gemini

Gemini in Gmail is Google’s built-in AI assistant for email creation and management. It supports drafting messages, rewriting text, summarizing long threads, creating structured responses, and generating content based on prompts. It operates within Gmail and leverages Google Workspace data to produce context-relevant output.

Pros

  • Seemless integration with Gmail, making it easy to integrate.
  • Can also be used to summarize received emails.

Cons

  • Is not trained on your history accurately and scores relatively low at drafting replies according to actual previous conversations. Drafts generic replies instead.
  • It's hard to get AI to respond in your own tone of voice.
  • Requires you to use Gmail natively.

When to choose Gemini over Fyxer AI?

Opt for Gemini if you prefer an AI assistant natively integrated within Gmail for ease of use. However, be aware that Gemini's outputs tend to be generic and lack personalized responses that accurately capture your previous conversations. In contrast to Fyxer AI's additional functionalities, Gemini may still not meet the high expectations for context-aware replies.

3. Copilot

Copilot in Outlook is an AI assistant integrated into Microsoft 365. It helps with drafting emails, summarizing threads, generating replies, organizing information from your inbox, and handling routine communication tasks. It works directly inside Outlook and uses data from Microsoft 365 to provide context-aware suggestions.

Pros

  • Seemless integration with Outlook.
  • Brings other features like AI summarizations.

Cons

  • It's a reactive assistant rather than an autonomous agent that decides itself whether or not it will draft a reply.
  • Doesn't directly use your email history when drafting replies, rather using generic models.
  • Requires you to use Outlook natively.

When to choose Copilot over Fyxer AI?

Use Copilot if you're looking for an AI assistant within Microsoft 365 that helps manage routine communication tasks. It's important to note, however, that Copilot lacks personalization as it relies on generic training rather than your email history to draft replies. This can limit its effectiveness compared to more tailored solutions like Untyped.

4. Superhuman

Superhuman is a productivity suite built around an AI‑native email app that helps teams move through their inboxes faster while staying perfectly coordinated. They triage incoming messages with a split inbox to surface what matters, draft replies that sound like you and can even send on your behalf, and remind you to follow up on time. They let you share and comment on live email threads with teammates, automate repetitive responses with Snippets an use instant replies.

Pros

  • Superhuman has got a calendar integration.
  • With Superhuman, you can connect social media channels for insights.

Cons

  • It's yet another new complicated tool: Superhuman doesn't work in Gmail or Outlook and forces you to learn a new interface that breaks current workflows.
  • There is no flexibility to train the AI tools within Superhuman on additional information.
  • Starts at 40 usd per month if you need basic features like AI drafting, without a free trial.

When to choose Superhuman over Fyxer AI?

Superhuman is a good choice if you want a productivity-focused AI suite that enhances email management. Unlike Fyxer, it allows for swift triage and response drafting, although it may not integrate with existing workflows. Consider switching if you prioritize a tool that streamlines your overall email experience.

5. Shortwave

Shortwave is an AI‑powered email client designed to automate your inbox and workflow. They use advanced AI to organize and prioritize emails, filter and label messages using plain‑English scripts,. They offer AI search that can analyze your team’s emails and attachments for answers, smart autocomplete suggestions, and scheduling tools that check availability and create calendar events.

Pros

  • Clean, intuïtive custom interface.
  • Affordable pricing.

Cons

  • AI replies lack personalization and don't match your tone of voice.
  • It's yet another new complicated tool: Shortwave doesn't work in Gmail or Outlook and forces you to learn a new interface that breaks current workflows.
  • Works only in combination with Gmail.

When to choose Shortwave over Fyxer AI?

Select Shortwave if you value advanced organization and automation of your email inbox with an intuitive interface. While it might not connect to external data sources, its design focuses on enhancing workflow efficiency. This may be beneficial compared to Fyxer AI, which lacks such innovative features.

Conclusion about making the switch

Switching from Fyxer AI to Untyped is advantageous due to its advanced personalization capabilities and continuous learning from your email history. Unlike Fyxer, which struggles with customization and reliability, Untyped offers a more tailored communication experience. For users seeking effective, context-aware responses, Untyped emerges as the superior choice.
