In their own words
Fyxer
Fyxer is an AI assistant for email and meetings that organizes inboxes, highlights priorities, and helps manage follow-ups. It labels messages by priority and brings emails needing a reply forward. It can draft replies in the user’s voice, but the user reviews and sends them; Fyxer says it never sends email on the user’s behalf. Its meeting notetaker captures meetings, summarizes action points, and drafts follow-up emails. Calendar tools suggest meeting times and support scheduling links and invitations. Fyxer Chat searches email threads and meeting notes, answers questions, and drafts emails in the user’s voice. Listed integrations include Gmail, Outlook, Google Calendar, Outlook Calendar, Google Meet, Microsoft Teams, Zoom, and Slack. Fyxer says it is SOC 2 Type II and ISO 27001 certified, GDPR and HIPAA compliant, and does not use user data to train third-party AI models. It says participants are notified before it joins a call and meeting materials are private by default. Listed platforms are API, iOS, and web. The service requires cloud-hosted Microsoft accounts and does not support on-premise Exchange, POP3/IMAP inboxes, or Apple Mail. The maker focuses on external-facing roles with heavy inbox workloads.
Spark +AI
Spark +AI adds an AI assistant to Spark’s email app on Android, iOS, macOS, and Windows. It can search email, attachments, calendar items, and meeting notes, as well as draft or rephrase messages, proofread grammar and clarity, and translate. The assistant can check colleagues’ availability, schedule meetings, draft and send emails, and organize the inbox. It works with Gmail and Google Workspace, Outlook and Office 365 including Exchange Online, iCloud, Yahoo, and standard IMAP accounts; supported attachments are PDF and TXT. Spark lists integrations including Notion, Asana, Slack, Todoist, Zoom, Microsoft Teams, and HubSpot, with Salesforce and Pipedrive marked as coming soon. Spark says email and request history are processed locally, but a few query-related emails are sent to its AI provider; provider copies may be kept for up to 30 days for abuse monitoring. Spark says providers do not train models on user data, and AI can be disabled. Free includes five lifetime Meeting Notes; Plus costs $10 a month per user with 40 monthly notes, and Pro costs $20 a month per user with unlimited notes. AI features also use monthly quota.
