For years, accessing software meant downloading a dedicated mobile application, setting up an account, and navigating a custom user interface. That pattern is rapidly shifting as a new wave of artificial intelligence agents moves directly into standard messaging apps. Rather than asking users to monitor another inbox or learn a new software suite, these agents operate via iMessage, RCS, WhatsApp, Telegram, Signal, and traditional SMS. Users simply text them instructions, and the systems carry out tasks across calendars, emails, travel bookings, and web services.
The transition from standalone mobile apps to conversational messaging threads represents a fundamental change in how software is deployed. By meeting people where they already spend hours each day, text-based agents lower the friction of delegation. Backed by billions of dollars in venture funding, startups in this category are racing to handle everything from personal scheduling to family logistics, creative work, and enterprise coordination.
Here is a comprehensive breakdown of the leading AI agents currently operating through text messages, organized by their core capabilities and focus areas.
Heavy Hitters and Big Valuations
Several startups in the messaging agent space have captured significant market attention and venture backing over the past year.
- Instinct: Among the most heavily capitalized startups in the consumer AI sector, Instinct reached a $10 billion valuation after securing a $1 billion funding round, following an earlier $350 million raise at a $2.5 billion valuation. In addition to handling travel planning, grocery orders, ticket purchases, and subscription cancellations via text and voice, Instinct assigns users dedicated email addresses for their assistants. This allows the agent to create accounts and contact third-party businesses without cluttering personal inboxes. The company has also expanded into making automated phone calls, though its high level of autonomy has sparked discussions regarding privacy and account security.
- Tab: Emerging from stealth with a valuation of $300 million, Tab focuses on delegating everyday errands through iMessage and WhatsApp. Backed by investors including SV Angel, Valar Ventures, and American Spirit, the service handles tasks ranging from ordering groceries to locating gifts on behalf of users.
- Poke: Poke made headlines after Apple approved it as the first AI agent available on the Apple Messages for Business platform. Originally launched to handle calendar updates, fitness tracking, and smart-home management, parent company The Interaction Company of California was acquired shortly after by AI coding company Cognition in a deal valued in the low nine figures.
General-Purpose Personal Assistants
For users seeking an all-around digital assistant to organize schedules, track reminders, and conduct online research, several platforms offer flexible toolkits through chat apps.
- Caddy: Operating inside iMessage for iOS and RCS for Android, Caddy focuses on converting fragmented communication into structured action items. Available in public beta, it connects to existing calendars and message threads to spot dates, to-do lists, and reminders that need to be captured, eliminating the need to check separate productivity apps.
- Comma: Designed as an open-source tool for both work and personal tasks, Comma operates across desktop browsers and file systems while remaining accessible through Signal, Telegram, and WeChat. The service maintains cross-device memory, generates morning briefings, flags pressing responsibilities, and verifies its own work before presenting completed items for user approval.
- Folk: Accessible through iMessage, WhatsApp, and Telegram, Folk distinguishes itself by running tasks on an isolated cloud computer. This setup allows the assistant to execute code and carry out multi-step actions, such as tracking flights and making dining reservations. Folk offers a free tier alongside an $8.33 monthly Pro plan for unlimited background tasks.
- Martin: Reachable via SMS, phone calls, WhatsApp, email, Slack, and an iOS app, Martin functions as a comprehensive task manager. It sends messages, places phone calls, and provides daily morning summaries, with pricing starting at $21 per month.
- Iris: Powered by Hermes Agent, Iris allows users to hand off tasks in iMessage by connecting their everyday apps. The system retains context over time and proactively follows up on outstanding items rather than waiting for user prompts.
- Rene: Positioned as an all-purpose contact in iMessage, Telegram, and WhatsApp, Rene handles natural-language delegation. It features an integrated browser, writes code, builds slide decks, generates images, and manages online shopping.
- Tomo: While most assistants operate in private direct messages, Tomo can join group chats on iMessage. It assists with group scheduling, goal tracking, web searches, video review, and photo editing, with subscriptions starting at $19.99 per month.
- Pally: Designed to feel like messaging a friend, Pally links to WhatsApp, Gmail, and Google Drive to keep tabs on receipts, files, and upcoming plans. Its free tier includes 15 minutes of voice calls each month, with paid options starting at $25.
Household and Family Coordinators
Managing family schedules, school updates, and domestic logistics has become a major proving ground for conversational agents.
- Fambot: Operating across SMS, web, iOS, and Android, Fambot acts as a family chief of staff. It connects to Gmail, Google Calendar, Outlook, and WhatsApp, delivering an automated evening summary of the next day's events, school packing lists, and activities. Parents can reply directly to adjust schedules. Fambot raised $3.5 million in pre-seed funding and remains free during its beta period, with plans to introduce a subscription model later.
- Ollie: Aimed at organizing school notices, group chats, and family calendars, Ollie delivers relevant updates via text. The company distinguishes itself on the security front by achieving SOC 2 compliance, making it one of the few family-focused AI assistants with that certification. Plans begin with a free tier, moving to $25 per month for 150 messages and $100 per month for 1,000 messages.
- Ohai: Built to help households balance overlapping responsibilities, Ohai accepts text messages, voice memos, and forwarded emails to coordinate chores, meal prep, and calendars across multiple family members. Plans start at $9.99 per month.
- Orbits: Backed by Andreessen Horowitz's Speedrun fund, N49P, and Garage Capital, Orbits coordinates household chores and manages communication with external service providers. Families can text Orbits to request home service quotes, book dinner tables, and reschedule appointments.
Specialized Workflows: Work, Travel, and Content
Other startups are tailoring messaging agents to specific professional and lifestyle use cases.
- Town: Geared toward professional environments, Town provides an assistant known as a Townie that learns individual working habits. It integrates with Slack, email, calendars, and documents to automate recurring office tasks. The company raised a $55 million Series A round led by Andreessen Horowitz and Forerunner.
- Miso: Applying conversational agents to travel logistics, Miso operates inside iMessage to pair AI trip planning with human travel specialists. The platform tracks loyalty points, monitors flight changes, and generates personalized itineraries.
- Stanley: Built for content creators, Stanley connects to Instagram and accepts voice notes over iMessage, Telegram, and the web. It converts those inputs into draft captions, scripts, and content calendar entries to maintain steady publishing schedules.
- Szn: Aimed at businesses needing cross-channel coordination, Szn handles inbound emails, voice notes, and messages in a single thread, executing phone calls and follow-ups. The company reports having served more than 7,500 businesses across 16 countries.
- Skye: Developed by Signull Labs, Skye takes an alternative route with an agentic home screen concept for iPhone. Instead of waiting for text prompts, it analyzes connected services to present contextual cards, audio summaries, and meeting preparations.
Autonomy, Privacy, and Device-Level Execution
As AI agents gain deeper access to personal data, startups are adopting contrasting approaches to identity, privacy, and execution.
Wajo addresses security by isolating its assistant, Fo, with its own dedicated phone number, email address, and payment card. This design allows the agent to book services and interact with merchants without requiring direct access to the user's personal financial credentials. In situations where automated workflows hit a roadblock, Wajo incorporates human operators to step in and finish the task.
At the opposite end of the architecture spectrum is Underdog, a privacy-oriented assistant launched in an invite-only beta. Rather than routing personal data through external cloud servers, Underdog runs its models locally on Mac and Windows computers, with mobile platforms planned for later releases. The team has committed to an ad-free model while keeping user data strictly on local hardware.
What Happens Next
The proliferation of text-based AI assistants highlights a clear industry trend: consumers and professionals prefer delegating tasks through communication channels they already use, rather than switching between siloed applications.
However, significant hurdles remain before these assistants become universal utilities. Privacy and security concerns loom large, particularly as agents gain the ability to send emails, place voice calls, and make financial transactions on behalf of users. Furthermore, high ongoing subscription prices across many services will test consumer willingness to pay for conversational convenience.
As tech giants continue refining their own platform-level intelligence within operating systems, third-party agents will need to prove that their cross-platform reach, custom tool integrations, and specialized workflows provide lasting value inside the messaging inbox.
