7 Best Sidekicks Alternatives in 2026
Sidekicks (sidekicks.chat) is a no-app, no-signup AI companion you reach by texting one phone number. You text “Hello” and start chatting in seconds — swappable personas (a productivity helper, a nutrition coach, a wellness buddy, and companion characters), reminders, to-do lists, photo-to-checklist scanning, and group-chat support. It’s deliberately simple, with a free tier and a $19.99/month Pro plan.
That simplicity is the whole point — and the limit. Sidekicks has no email, no real calendar integration, and no third-party app connections. It’s a personal companion that talks to you; it can’t act on your behalf toward anyone else. If you want a text assistant that actually runs your inbox, calendar, and tools, here are seven Sidekicks alternatives.
1. Carly
Sidekicks is a companion; Carly is a coworker. Carly is an AI agent platform you email or text like a colleague. Each agent has its own name and email address, so it can be client-facing — emailing customers, scheduling meetings, and updating your tools — not just chatting back.
Where Carly pulls ahead of Sidekicks:
- Real email. Carly reads, drafts, sends, and organizes across Gmail and Outlook. Sidekicks has no email at all.
- Real calendar. Carly books and reschedules on your connected Google or Outlook calendar. Sidekicks only sets its own text reminders.
- 200+ integrations — Drive, Slack, CRMs, and more. Sidekicks has none.
- Zapier-style automation workflows across your tools, versus a self-contained chat bot.
Best for: Anyone who wants the same “just text it” ease but with an assistant that does real work.
2. Poke
Text-message AI assistant from The Interaction Company that connects Gmail or Outlook and handles email, calendar, and “recipes” over iMessage, SMS, Telegram, or WhatsApp.
What makes it different from Sidekicks: Poke connects your inbox and calendar and acts on them — Sidekicks can’t. Poke still won’t email outside your contacts. See Poke alternatives.
Best for: People who want a text assistant that handles real email and calendar.
3. Martin
iOS-first AI assistant (trymartin.com) that manages email, calendar, and reminders through voice and text.
What makes it different from Sidekicks: Martin is a true personal assistant connected to your accounts, not a standalone chat companion. See Martin alternatives.
Best for: iPhone users who want a voice-first personal assistant.
4. Tomo
Text-first personal AI (tomo.ai) focused on goals, habits, and accountability, with auto-generated trackers.
What makes it different from Sidekicks: Both are personal and self-contained, but Tomo specializes in habit coaching with persistent memory. Neither does client-facing work like Carly. See Tomo alternatives.
Best for: People who want a habit and accountability coach over text.
5. Allora
Text-message reminder assistant (textallora.com) popular with ADHD users — natural-language reminders, voice-memo capture, and link/video summaries, with Google and Apple Calendar awareness.
What makes it different from Sidekicks: Allora at least syncs with your calendar for scheduling, where Sidekicks only sets internal reminders — but it has no email either. See Allora alternatives.
Best for: People who want simple, calendar-aware reminders by text.
6. Ohai
Consumer “life assistant” (ohai.ai) for busy households — scheduling, reminders, and family logistics over chat.
What makes it different from Sidekicks: Ohai connects to a household’s calendar and logistics rather than acting as a personal companion. See Ohai alternatives.
Best for: Parents and households managing family logistics.
7. Lindy
AI executive assistant that triages your inbox, drafts replies, schedules meetings, and sends proactive alerts over iMessage.
What makes it different from Sidekicks: Lindy works your actual inbox and calendar; Sidekicks doesn’t touch either. See Lindy alternatives.
Best for: People who want a proactive inbox assistant.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
