Solin Personal AI Assistant Launches Free Tier for Email, Calendar, Tasks

Solin is a personal AI assistant designed to handle busywork across work and home life without constant user direction. The product emphasizes three core capabilities: proactive action (handling tasks in the background), memory (retaining user preferences and context), and tool integration (working within email, calendar, and other existing applications).

In practice, Solin demonstrates its functionality through concrete examples—for instance, when asked "Reschedule my 2pm to Thursday and let them know why," it moves the meeting with Sarah to Thursday at 2pm (checking both calendars for availability), drafts and sends a polite explanation email, and ensures no other calendar conflicts are created. This saves manual work: calendar hunting, email drafting, and follow-up coordination.

The assistant builds memory across conversations, tracking user preferences (e.g., "Prefers short, direct emails"), important dates ("Mom's birthday is October 12th"), recurring tasks ("Rent is due on the 1st of every month"), and rules ("Never send a payment or purchase without asking me to confirm first"). Users see a dashboard where they can view, edit, or remove remembered information.

Solin's pricing is tiered. The free plan ($0/month) provides ~50 messages/day equivalent, the Haiku model, 2 inboxes, 3 integrations, full memory, and the Proactive Engine (1–2 active background pings). Plus ($18.99/month) unlocks a standard monthly usage pool, Claude standard model, 5 inboxes, 200+ integrations, and computer use capabilities. Pro ($34.99/month) offers ~7× the usage pool, model choice, uncapped inboxes and integrations, generous computer use allocation, and Solin Calling (Pro-exclusive phone feature). Enterprise pricing is custom. During launch, Plus and Pro are invite-only; users can join a waitlist to gain early access. The free tier requires no credit card and can be activated immediately.

Solin positions itself as fundamentally different from conversational AI assistants: rather than answering questions reactively, it takes autonomous action in the background and remembers context across interactions. The core value proposition—handling rescheduling, drafting emails, sending explanations—targets the high-friction administrative tasks that interrupt knowledge workers' day. By integrating with existing tools (email, calendar, payments) instead of creating a walled garden, Solin avoids forcing users to change workflows.

The pricing structure reflects a clear segmentation: the free tier ($0/month with ~50 messages/day) is a generous onboarding funnel, while Plus ($18.99/month) and Pro ($34.99/month) unlock substantially more capacity and integrations. Pro's inclusion of computer use and phone calling (Solin Calling) suggests the product is building toward more complex, hands-on automation. The decision to gate Plus and Pro behind a waitlist during launch indicates controlled rollout, likely to manage backend load and refine the experience before broad availability.
