Not another AI Notetaker. We close the loop. Loopion captures actions, posts them to Teams/Zoom, and carries them forward until they're done.

As answered by people managing Loopion and Sembly.
Loopion's answer
Loopion is built for businesses who are serious about execution and propelling their organization to growth through accountability of thier teams.
It is designed for organisations that already know how to create plans and actions but need a better way to make sure those commitments actually turn into results.
Loopion is particularly powerful for:
As organisations grow, accountability becomes harder. More meetings mean more actions, more owners, more deadlines and more opportunities for important commitments to disappear.
Loopion gives leaders visibility without turning them into professional chasers.
Know what was agreed. Know who owns it. Know what is overdue. Know what still needs to happen.
Because businesses don't grow by creating more actions. They grow by executing the right ones.
Sembly's answer:
Sembly is designed for professionals who run client relationships through meetings and need to create deliverables from those conversations.
The primary audience includes:
Loopion's answer
Loopion came from a problem seen by its CEO repeatedly over more than a decade of operating inside large organizations and billion-pound enterprises.
The businesses were not short of meetings.
They were not short of ideas.
They were not even short of actions.
They were short of consistent execution.
A meeting could end with complete agreement about what needed to happen, yet days later managers were chasing updates, people were trying to remember what they had committed to and valuable actions were quietly disappearing into meeting notes.
AI notetakers solved part of the problem.
They could tell you what happened.
But they still left the business responsible for making sure what happened next actually got done.
That gap became Loopion.
Capture the meeting. Extract the commitments. Establish ownership. Remember the history. Bring unfinished actions back. Keep doing it until they are complete.
Loopion was not built from a tech expert perspective, it was built from an operator's perspective of what real life in businesses looks like and based around one simple principle:
*Accountability drives execution. Execution drives results. Results drive growth. *
Meetings create actions. Loopion closes the loop.
Sembly's answer:
Sembly AI was founded in early 2019 by executives who have successfully grown companies from small startups to large operating entities that were subsequently sold to bluechip companies. The founders have a combined 40 years of hands-on experience supporting large transformation efforts in Fortune 500 organizations.
Loopion's answer
Loopion combines modern generative AI, large language models and speech intelligence to turn meetings into accountable execution.
Its technology powers:
The technology is sophisticated, but the objective is deliberately simple:
Turn conversations into actions. Actions into execution. And execution into results.
Sembly's answer:
The primary technologies used for building our product are proprietary.
Loopion's answer
Loopion is newly launched and is currently building its founding customer base.
We are working with early adopters across a mix of large and smaller organizations who want to fundamentally improve accountability and execution across their organizations.
Customer names and case studies will be published as deployments progress and organisations approve public disclosure.
We would rather earn the case studies than invent the logos.
Sembly's answer:
Sembly's customers include MIGSO-PCUBED, one of the world's largest project management consulting firms, along with PMI, Dr.Reddy’s, and Payroc.
More broadly, Sembly serves:
10,000+ professional teams worldwide use Sembly to run client engagements.
Loopion's answer
Businesses don't have an action-creation problem. They have an execution problem.
Every day, businesses hold meetings, make decisions, assign actions and set deadlines. The failure happens afterwards: actions disappear into notes, people forget what they owned, managers start chasing, and execution slows down. Its not lack of enthusiasm or dedication that stunts a businesses growth or slows down acheiving objectives, its the lack of tracking and ensuring execution actually happens. The question isnt why choose Loopion, its how much will it cost you and your business if you dont ensure consistant execution in your organization happens everyday?
Loopion closes the accountability loop.
Loopion uses two-pass AI action extraction to identify commitments, validate them and turn them into clear actions with owners and deadlines. But unlike traditional AI notetakers, that is where Loopion starts — not where it stops.
Outstanding actions are automatically carried forward and resurfaced inside future Microsoft Teams and Zoom meetings until they are completed. No more forgotten actions, only re-enforced execution.
Then there is Ask Loopion.
Ask Loopion remembers every meeting in a recurring series, not just the meeting you are looking at today. Ask what was decided four weeks ago, two months ago, who committed to something, when a decision changed or what is still outstanding — and Loopion brings the context back instantly.
ALSO THERE IS NO PER SEAT PRICING, INVITE THE WHOLE TEAM FOR THE SAME COST. JUST PAY FOR THE MINUTES YOU USE
Other meeting tools document what happened. Loopion drives what happens next.
Sembly's answer:
While Most AI meeting tools stop at note-taking, Sembly automates the entire post-meeting workflow.
1. Meetings that turn into deliverables Sembly produces proposals, project briefs, status reports, gap analyses, board summaries, and investment memos. Professional teams receive complete client-ready documents after every call.
2. Heavy focus on Professional Services Sembly is built specifically for consultancies, agencies, IT outsourcing firms, PMOs, and venture funds whose work centers on client meetings and deliverables.
3. Intelligence across the entire meeting history Sembly's Multi-Meeting AI Chat works across your full meeting history, surfacing patterns, recurring themes, and observations that no single meeting reveals.
4. Connection with existing stack Sembly connects to Claude, ChatGPT, and other AI assistants through the Model Context Protocol.
Loopion's answer
Because meeting notes don't grow businesses. Execution does.
There are plenty of AI tools that can record a meeting, generate a transcript and send you a summary.
*The question isnt why choose Loopion, its how much money are you willing to continue to spend on poor execution that does not push your teams to lead your organization where you want it to go? *
Loopion was built to solve the much bigger problem:
Did the things you agreed actually get done?
Loopion turns conversations into accountable execution. Actions are extracted using two-pass AI, assigned to the right people and then kept alive after the meeting.
If an action remains outstanding, Loopion can carry it into the next meeting and surface it again directly inside Microsoft Teams or Zoom.
No hiding. No "I forgot." No "I thought somebody else was doing it."
And unlike tools that treat every meeting as an isolated event, Ask Loopion remembers the entire meeting series. Your team can ask about decisions, commitments and conversations from weeks or months earlier without searching through transcripts or relying on human memory.
Execution drives results. Results drive growth. Accountability drives execution.
If you only want another extremely clever or sharp AI notetaker, you have plenty of choices.
If you want your meetings to drive execution, choose Loopion.

Sembly's answer:
1. Sembly vs. meeting AI Most meeting solutions transcribe meetings and extract action items. Sembly does that and produces the proposals, project briefs, and status reports that teams write after every client call.
2. Sembly vs manual document creation Most Professional Services teams still write proposals, briefs, and reports manually. Sembly can generate professional documents from the meeting content within minutes, saving time and effort.
3. Sembly vs AI assistants Teams that paste transcripts into ChatGPT do it manually, one meeting at a time. Sembly integrates directly with meeting platforms, captures every call, and generates notes, tasks, and deliverables. For teams that want both, Sembly connects to Claude and ChatGPT through the Model Context Protocol.
4. Sembly vs proposal software Proposal tools help teams format and send documents. However, they still require someone to write the content. Sembly generates the proposal content directly from the discovery call, so teams review and send rather than write the first draft themselves.
