ByteDance built it for itself. Then the rest of the world asked to borrow it.
Most collaboration software wants a slice of your team. Chat here. Docs there. Video somewhere else. Then a project tool, then a wiki, then a form, then a spreadsheet with automations, then a translator, then the calendar. Seven tabs. Six logins. One human losing their mind.
Lark is built for the person who stopped counting tabs and started resenting them. It is one place where the meeting, the recap, the follow-up task, the spreadsheet the recap links to, and the chat thread arguing about the spreadsheet all live together. The word for that is relief.
"You do not adopt Lark. You retire six other things."
Who it is for: mid-market and enterprise teams that are tired of stitching subscriptions together. Multilingual teams love it because translation is native, not a plug-in. Fast-moving product teams love it because Base (its spreadsheet-database hybrid) does what Airtable does, without leaving the app.
Somewhere around 2016, ByteDance had a problem the entire tech industry has: too many people, too many time zones, too many tools, too little sleep. The company built an internal comms platform to fix it. That tool got a name (Feishu, "flying message") and became the operating system for one of the fastest-growing companies on earth.
In April 2019, ByteDance let the international version out of the barn. They called it Lark, based it in Singapore under Lark Technologies Pte. Ltd., and quietly began shipping features at a pace most SaaS companies reserve for their pitch decks.
By April 2020, when the world went remote overnight, Lark went free across Southeast Asia. That was not charity. That was distribution. It worked.
2016 - Built internally at ByteDance
2018 - Becomes the company's official platform
2019 - Public international launch
2020 - Free across Southeast Asia
2025 - Restricted in the U.S. under ByteDance app law
2026 - AI meeting minutes + Base automations expand
The trick with Lark is not any single feature. It is that each feature knows the others exist. A meeting knows its transcript. The transcript knows how to become a task. The task knows which doc it lives inside. The doc knows which chat thread argues about it.
1-to-1, groups, threads, and channels. With translation baked into the message bar so your Jakarta-Tokyo-Berlin thread stops needing a moderator.
HD calls with AI transcription, live captions, and auto-generated minutes. Action items appear before someone has to volunteer.
Real-time collaborative editing with embedded tables, mind maps, and files. The wiki holds it all together without a separate app.
A spreadsheet that thinks it is a database. Custom formulas, views, automations. Airtable-shaped without the Airtable bill.
Shared team time that respects time zones and does not require a plug-in to book across companies.
Native goal setting with alignment visualization, so leadership can see which teams are pulling in which direction.
No-code forms, approval chains, and automations for the small operational tasks that quietly eat every week.
Live translation across 100+ languages inside chat, docs, and meetings. Global teams do not need a lingua franca. Lark is the lingua franca.
$0 - up to 20 users. Unlimited messaging, video meetings, docs. 100 GB storage. This is where most small teams start and stay.
from $12/user/month - more storage, admin controls, guest access, advanced meeting features, and workflow automation for scaling teams.
Custom pricing. Advanced security, compliance, dedicated support, unlimited storage, and the controls large orgs need before saying yes.
Move chat off Slack into Messenger. Move meetings off Zoom into Lark Meetings. Move a shared spreadsheet into Base. That is your week. Do not try to migrate everything at once. Lark rewards patience.
Record a call. The transcript arrives. The action items are already tagged to people. Pin them to a Base row. Now the follow-up is a workflow, not an email chain that dies on Friday.
Turn on real-time translation in a channel. Watch a Manila designer, a Berlin engineer, and a Tokyo PM stop apologizing for their English. Everybody types in their own tongue. Everybody reads in theirs.
Wire OKRs to Base rows. Now the quarterly review is not a slide deck. It is the workspace, opened. Alignment stops being a poster on the wall.
Two birds, one company. Lark and Feishu ("flying message") are technical siblings that never talk. Separate services, separate data centers, separate universes.
Flutter under the hood. Lark is built on Flutter and Dart, which is why it feels identical on your Mac, phone, and browser. One codebase. Fewer excuses.
Dogfooded at scale. Roughly 150,000 ByteDance employees use Lark every day. If it broke, TikTok would notice.
Not for U.S. users. As of January 2025, Lark is restricted in the United States under ByteDance-related app laws. It is very much alive everywhere else.
ByteDance, the same company that owns TikTok. Lark is operated by Lark Technologies Pte. Ltd., based in Singapore.
Yes. Up to 20 users, with unlimited messaging, video meetings, docs, and 100 GB of storage on the Starter plan.
As of January 2025, Lark is not accessible to U.S. users due to restrictions on ByteDance apps.
Feishu is the China-only version. Lark is the international version. They run on separate infrastructure, and data stays in its region.
In practice, teams use it instead of Slack, Zoom, Google Docs, Notion, Airtable, and Asana. Not all at once. But often close.
