The Thinking Messenger.

Messaging reimagined with AI: fast, private, and built for people who think ahead.

Chats, your team’s work, your assistant, and your money in one place, with an AI that sees the work, not just the chat window.

Linsa on iPhone: the Chats tab with conversations and drafts.

Why we built it

Your work is in five apps. Your AI is in a sixth.

A team runs on one product for talking, another for tasks, a third for notes, a separate assistant, and a separate wallet. Each has its own logic, its own permissions, and its own bill.

Fragmentation

Switching tools means copying context by hand: the same thread pasted into a task, then into a note.

AI on the outside

Assistants live beside the workplace, so the connection to your actual work is something you build yourself.

Closed platforms

You either accept the compromises of one vendor or migrate everything you have built every few years.

Linsa puts the layers in one product, keeps one context between them, and leaves the platform open.

Lin

Lin. An assistant that already knows what you’re working on.

Lin is built into Linsa, not bolted onto it. It reads your conversations, notes and Spaces, strictly inside your own permissions.

  1. You ask in plain language.
  2. Lin reads a day of messages and pulls out what has to be done.
  3. The task lands in the chat, already assigned.
Lin reads a day of messages, extracts action items and creates a task with an assignee.

Lin in its own chat

A continuous conversation with Lin, powered by Claude Sonnet, that creates notes and tasks right inside the chat as widgets.

Lin over any chat

Swipe up inside a conversation and Lin opens on top of it. It sees the history, answers questions about it and summarizes.

Reads your context

Lin sees the current chat, your notes and your Spaces within your permissions, and searches by intent, not by exact wording.

Memory

A context block you edit by hand or just by asking. Lin keeps what you explicitly ask it to keep, and nothing else.

Vision

Send Lin a photo and it reads what’s in it, from a screenshot of a thread to a page of handwritten notes.

Voice

Call Lin. Real-time voice with a parallel text stream, and action widgets landing in the chat as you talk.

Semantic search, summarization, drafts, translation and tone adaptation are things Lin does, not separate features you switch between. You phrase a request in plain language and get an answer that combines several sources in one action.

Summarize
Summarize a conversation, a call or a document: forward it to Lin, or use the overlay.
Turn talk into work
Create a task or a note from the conversation; the result appears as a widget in the chat.
Write it better
Generate a draft, translate a message, adapt the tone.

Response style and length are yours to set.

Lin is only the first one.

Agents

Agents. Build your own agent. Put it where the work happens.

Any user can create an agent for any task: a name, an avatar, instructions in plain system-prompt form, configurable memory, and the set of tools you choose.

Perfect. I will take the changelog.

Message #release

Agents are members, not bots. They stand in the list under their own name and answer when the team calls them.

The builder

Name, avatar, handle, system prompt, tools. Test it in preview before anyone sees it.

In group chats

Add an agent to a group as a participant. It sees the conversation from the moment it joined.

In Spaces

Inside a Space it sees channels, tasks and notes by permission, comments on issues and closes them.

Triggers and schedule

Fire on a mention, on a chat event, or on a schedule. Stay quiet the rest of the time.

Knowledge

Attach files, notes, Spaces and web pages. The agent searches across all of them at once.

Skills and plugins

Skills are instructions and assets. Plugins execute: a script, an external API, an MCP server.

Ready-made templates you can copy and change: HR, Support, Taskmaster, Analyst, Developer.

Inside a Space: an onboarding agent, a secretary agent, an analyst agent.

  • Explicit permission confirmation
  • Audit log of agent actions
  • Versioning
  • Sessions you can archive and restart

Spaces

Where the team’s work actually lives.

A Space holds the team’s group chats and channels, its agents, tasks, notes and files. Each module is visible according to the permissions the owner grants.

A Linsa Space on the desktop: channels on the left, a thread with the team’s agent in the middle
Channels, threads and the team’s agents in one place. Lin answers in the channel like anyone else on the team.

Functionally, a single Space replaces the combination of a messenger, a project tracker and a knowledge base, with the assistant and the payment layer already inside.

The same Space, seen as a board. Same members, same permissions, same conversation one click away.

Channels and threads

Public and private channels, group chats, and topics inside every one of them.

Tasks and kanban

Statuses, priorities, labels, subtasks, dependencies, assignees, sprints and time tracking.

Views

Kanban, list, calendar, roadmap, and any filter you save as a view of your own.

Notes

A team wiki: page hierarchy, checklists, tables, code blocks, links and version history.

Files

Storage inside the Space, with previews, versioning, a directory tree and search.

Calendar

Events, meetings across time zones, task deadlines, two-way sync with external calendars.

Whiteboard

Freehand drawing, sticky notes, shapes, image import, live collaboration, export to PNG.

Dashboards

Reports on activity, task statuses, agent usage and AI spend, on a schedule.

Owner · Admin · Member · Guest, custom roles with per-channel and per-feature permissions; invite by link, email or phone; external guests with limited access.

Messaging

Everything you expect from a messenger. Then the rest.

Text with formatting, reactions, quotes, forwarding, editing, pinning. Voice and video messages, media and files, group calls and channels.

Familiar on the surface. Underneath, Lin transcribes the voice message and turns the call into a card in the thread.

  • Reply, quote, forward with or without attribution
  • Pin, schedule, self-destruct
  • Drafts per chat

  • Search

Groups and channels

  • Create a group, join by link, QR invitation card
  • Roles from member to owner
  • Topics inside a group
  • Public and private channels with posts, reactions and comments

Calls

  • One-to-one voice and video
  • Group calls with screen sharing, grid and speaker view
  • Raise hand, background effects and AI noise removal
  • Recording with automatic transcription and live captions

Media

  • Fullscreen viewer with pinch-zoom
  • Video with subtitles
  • Voice messages with waveform and transcription by Lin
  • Round video messages
  • Files of any type with previews
  • Media / Files / Links / Voice tabs inside every chat

Every conversation aggregates what passed through it: Media, Files, Links and Voice, each on its own tab.

Wallet

Send money where you’re already talking.

A built-in multi-currency wallet with the native LIN token: balance, major tokens, full transaction history, and transfers that happen inside the conversation.

LIN is the currency of the Marketplace: it settles purchases and pays the authors of agents.

Marketplace

Someone already built the agent you need.

One catalog of ready-made agents, Space tools, widgets and templates. You add them the way you add apps.

Authors publish and get paid in LIN, and the main share of every sale goes to the author. When you add an agent, you confirm exactly what it is allowed to reach.

A slice of the catalog

Companies deploying on their own infrastructure get a private marketplace for internal agents and tools.

Home

Arrange the app around your day.

Home is the main screen, alongside Chats and Profile, and it holds the way into everything else: calls, Spaces, Marketplace, notes, Wallet. You choose what sits where.

Widgets for Lin, tasks, notes, calendar, wallet, recent chats and Spaces. Save presets for work and personal. Put one or two extra tabs in the bottom bar as shortcuts to anything on Home.

Two extra tabs, wherever you want them.

Everything you just saw stays yours.

Local-first

Your data lives on your device.

Linsa is built local-first: your data sits on your devices, and servers exist to synchronize between them and hold an encrypted copy.

Leaving the platform or losing access to a server doesn’t mean losing your data.

Your devicesEdge, close to youGlobal core

Offline. Syncs when you’re back.

Offline is not a mode. Write, edit and read with no connection. When the network returns, everything syncs: nothing duplicated, nothing out of order.

Nothing gets overwritten. Two people editing the same task merge cleanly; the same field resolves by a clear rule, not by whose signal was better.

A human and an agent in one document. Edits merge at the level of text fragments, so an agent can fill in a section while you rewrite a paragraph.

Permissions live in the data. The engine records who changed what, and an agent sees exactly what it’s allowed to see, and nothing more.

  • Device key stored only on this device
  • Face ID / Touch ID for sign-in and confirmations
  • 12‑word recovery phrase
  • Optional encrypted regions inside a chat
  • Audit logs for account and agent actions

Edge servers close to users and a global core that reconciles regions. We run them ourselves, so we control where data physically sits.

For companies

Run it on your own infrastructure.

Teams working with sensitive data can deploy Linsa inside their own perimeter, with isolated AI infrastructure and their own keys.

On-prem. Installers for Docker, Kubernetes and Linux; backup and restore; monitoring; high availability; migration tools. Cloud AI models can be replaced with local ones.

Single sign-on. SAML, OIDC and Active Directory.

Compliance. Data retention policy, DLP, extended audit logs, data localization; ISO 27001, SOC 2 Type II, GDPR and HIPAA on the compliance track.

Administration. Centralized billing, license management, a private corporate marketplace, custom SLA, white-label branding.

Availability

iOS today. macOS and Web next.

Linsa is available on iPhone through TestFlight. The macOS client is a native app in private testing, and Web, Desktop and Android follow once iOS is stable.
