Les meilleures appli Slack pour votre espace de travail en 2026

Slack has more than 2,600 apps in its app directory. Plenty of them are narrowly useful: for example, Slack's Vercel app is great if you're hosting web development projects, but it doesn't have any appeal outside of that.

But most businesses using Slack have the same broad needs: communication, team building, project management, automation, onboarding, and getting work done without lots of context switching. Plus a bit of goofing off, of course. Slack apps can help with all of this. And with embedded AI capabilities, they're increasingly becoming a way to do work rather than just chat about doing work.

I tested dozens of Slack apps that are likely to appeal to a broad demographic of hybrid and remote teams. Here are the best Slack apps I found.

Qu'est-ce qu'une application Slack ?

A Slack app is a helpful add-on that works with Slack to automate tasks and workflows, integrate third-party tools, or help your team have a better experience within your Slack workspace. Think of it as a virtual assistant that lives within your Slack channels, ready to jump into action. 

Some Slack apps are simple, single-purpose integrations, like the ones that link Google Drive to Slack or remind you when your colleagues' birthdays are coming up. Others, especially the newer AI-enabled Slack apps, act more like an actual team member: they can maintain context, work on their own, and follow up on projects without being asked.

Comment ajouter une appli Slack à votre espace de travail

"Voici un guide rapide étape par étape pour ajouter une appli Slack :"

2. Installez l’appli de votre choix en cliquant sur Ajouter à Slack.

   

3. Configurez les paramètres de votre appli dans Slack. Le robot vous guidera à travers tout ce que vous devez faire.

A few of these Slack apps are standalone apps, and they start working right when you install them. But you can't use the ClickUp Slack app without having a ClickUp account, and the same is true for most of the other apps on this list. If you don't see your preferred tools below, you'll probably find them on the Slack marketplace. If you don't, you can create your own Slack connection using Zapier, which connects to 9,000+applications.

Les meilleures appli Slack pour la gestion de projet

You probably aren't going to migrate to an entirely new project management tool based on the strength of its Slack integration. With that in mind, the best Slack app for project management is whichever project management tool your team already uses, so definitely start there. Otherwise, consider going with one of these.

Trello

Trello popularized the Kanban board style of visual project management, so it's no surprise that the Trello app for Slack allows you to create new cards, update existing ones, and receive notifications directly within Slack. You can also add an emoji to save Slack messages to your Trello Inbox, or click any message and select "Create card from Trello" to automatically populate a card based on the details of the message.

Asana

À l’instar de Trello, l’appli Slack d’Asana vous permet de créer facilement des tâches, de les attribuer aux membres de l’équipe et de définir des dates d’échéance directement à partir de vos conversations Slack. Vous pouvez également lier un projet à un canal Slack spécifique, qui publie les mises à jour du projet directement sur ce canal en temps réel, ce qui permet à tout le monde d’être sur la même longueur d’onde sans quitter Slack.

And if you subscribe to one of Asana's paid plans, you can use Asana AI within Slack to get AI-powered project summaries, insights, and recommendations.

ClickUp

The ClickUp Slack app allows you to create tasks, add them to specific projects, and even update task statuses without ever leaving your Slack workspace. You can also convert Slack messages into actionable tasks, or leave comments on tasks directly from Slack. ClickUp's rich link previews are especially helpful, making it easy to understand a project's context with a quick glance. And you can also send items from Slack directly to an AI-powered ClickUp "Super Agent" so they can act on it.

Slack can enhance your productivity—or totally drain it. Rather than adding yet another element of digital overwhelm, these Slack apps are worth installing because they make your existing work easier.

Notion

Plenty of teams use Slack for internal chat and Notion for their knowledge base, docs, and wikis. Rather than constantly jumping between the two, you can use Notion's Slack app to create a Notion database page from a message and receive notifications about edits happening in Notion. You can also paste a Notion link into Slack and get an auto-generated AI summary of the content.

Calendrier Google

The Google Calendar app keeps you on schedule without leaving Slack. You can see your daily agenda right within Slack, and you'll get pinged with reminders when it's meeting time. You can even respond to meeting invites directly from within Slack, without opening a new Google Calendar window.

L’application Google Agenda est particulièrement utile pour les équipes travaillant sur différents fuseaux horaires, car elle simplifie la planification et permet à tout le monde de rester aligné. Il met également automatiquement à jour ton statut Slack à " En réunion " lorsque tu es occupée, afin que tous ceux qui t'envoient un message sachent que tu n'es pas disponible pour le moment.

Google Drive

For teams that rely heavily on Google Drive, the Google Drive Slack app is a must-have. It notifies you about changes to documents, comments, and shared files directly in Slack, so you know right away if someone's left feedback—and you can reply to them from Slack, too. When someone requests access to a Drive file, you'll get an immediate Slack notification that lets you handle the request quickly from within the chat. You can even create new Docs, Slides, and Sheets without leaving Slack.

Si vous utilisez un autre système de gestion de fichiers, comme Box ou Dropbox, ils ont également des appli Slack.

Zapier

Zapier takes Slack productivity to another level by connecting your workspace with 9,000+ other apps and services. With the Zapier Slack app, you can automate workflows between Slack and all the other tools your team uses, including CRMs, email marketing platforms, and project management tools. Whether it's automatically creating Slack messages based on activity in other apps or posting updates from Slack to other platforms, Zapier makes it possible to automate almost any task.

You can even use Zapier MCP to connect Slack (and the rest of your tools) to your AI assistant like Claude or ChatGPT, so whether you live in a Slack window or an AI chat window, you can take actions across your tech stack without switching tabs.

Reclaim.ai

Reclaim, which is owned by Dropbox, automatically syncs your Slack status with your calendar, so colleagues see "In a meeting" or "Focus time" without any manual work on your part. It can also initiate Do Not Disturb mode, or help you quickly schedule time with colleagues using prompts like "find 30 minutes with @Serena this week."

While Slack now has its own built-in functions for things like Focus Mode, Reclaim is far more flexible: you can create recurring "Habits" blocks for things like routines, deep work, and personal time.

L'approuver

The Approveit Slack app automates approval processes directly in Slack, making it easier to handle everything from invoice approvals to time-off requests.

In cases where multiple people need to sign off on a decision, Approveit can notify all stakeholders and then update the requester once everyone has signed off. You can even delegate your approval authority to someone else while you're out of office (to avoid getting hit with a tsunami of unprocessed requests after getting back from vacation). 

AI has made much of this easier. If you're the one making a request, you can upload documents into Slack, and Approveit will extract the data, prefill any necessary forms, and prepare the request for you to review. And if you're a manager or finance team member with questions about past approvals, that data is at your fingertips in Slack in seconds.

Les meilleurs robots Slack pour la communication

Typing messages all day can feel limiting. Sometimes you need to see faces, hear voices, and remind yourself that your succulent plant and half-empty coffee cup aren't your only coworkers. Whether you want to chat on a leisurely video call or save time with async updates, these communication-focused Slack apps can help.

Zoom

The Zoom app for Slack lets you start or join video meetings directly from your Slack workspace. It simplifies the process of scheduling and joining calls, making it easier to move discussions from text to face-to-face conversations. Just type a simple slash command (/zoom), and your meeting can begin.

Once your meeting is over, Zoom's AI Companion kicks in, and you'll automatically get AI-generated meeting summaries in Slack. If you didn't attend the meeting, you can ask questions like "Was my name mentioned?" Optionally, Zoom can also automatically create a private Slack channel for Zoom meetings; internal attendees are automatically added, as are all post-meeting assets, like summaries, recordings, and chat links.

Métier à tisser

Slack now has a native async video solution called Clips, which works well for internal videos that are under five minutes long. But sometimes you need longer video clips—like trainings, demos, or detailed walkthroughs—and you need the option to share them on other platforms. Loom is still the best option for that. The Loom Slack app lets you watch embedded Looms directly within Slack, and you can start recording them there too.

Calendly

If most of your meetings are with external clients or partners, there's a good chance you use Calendly to schedule them. The Calendly Slack app keeps you updated with automatic meeting notifications directly in Slack whenever something is scheduled, rescheduled, or canceled, so you can quickly adapt your schedule to last-minute changes.

When you paste Calendly links into Slack, you'll get rich link previews with important information about your meeting. You can also see all your scheduled Calendly meetings for the day from within Slack on the app's home page.

Geekbot

If you've ever experienced the dreaded "meeting that should have been an email," you know how important it is to proceed with caution when asking for space on your colleagues' calendars. With Geekbot's Slack app, you can use async standups and check-ins to stay fully updated on what your team is doing without disrupting their day.

Instead of committing to a 15-minute daily video chat (which typically involves lots of listening to colleagues' status reports), your team gets automated questions from Geekbot in their Slack DMs. Geekbot consolidates the answers and shares the results; it also gathers sentiment analytics and trends over time. In addition to standups, you can also use Geekbot for retrospectives, polls, and surveys, and there are templates for common use cases like product development and HR processes.

Les meilleurs robots Slack AI

Toggling between multiple AI tools and Slack creates unnecessary friction in your workflow. AI Slack apps bring powerful artificial intelligence features right into your Slack channels, letting you generate content, analyze data, and get smart answers with a quick slash command. They also increasingly pull agentic activities into Slack, so you can delegate work to agents as if they were coworkers—and complete entire projects without leaving the comfort of your chat window.

Perplexity Computer

Perplexity's Slack app used to be a research assistant. Now, it's an embedded version of Perplexity Computer, a general-purpose AI agent. When you tag @Computer in a channel or a DM, it can search the web, pull from your Slack history, and connect to other tools; it then goes a step further and actually completes the task for you. Behind the scenes, Perplexity Computer has a real filesystem, browser, and integrations, runs in an isolated environment, and can design entire workflows and execute them for hours or days.

Claude Tag

Claude's Slack app has made some big strides lately. It's now known as Claude Tag, and it's focused less on being an AI assistant and more on being an actual team member within Slack. For example, when you tag Claude for coding tasks, it'll ask any questions necessary, complete the tasks asynchronously, and report back when they're done. Each channel has its own Claude, with its own memory and context that doesn't jump between channels. And if you enable the "Ambient behavior" option, Claude will also let you know proactively if it thinks you need to know something, and recommend next steps.

Note: Claude has retired its original "legacy" Slack app, which was more of a straightforward AI assistant. You need a Claude Team or Enterprise plan to use the new Claude Tag features. (I tried to use Claude's Slack app with a Claude Pro account and wasn't able to get it to do anything.)

ChatGPT

OpenAI has its own official Slack app too. It functions mainly as a 1:1 sidebar chat: you can open it, ask something, and get answers. Unlike Claude Tag, ChatGPT's Slack app doesn't (yet) offer ambient suggestions or hold persistent context and memory from across your entire channel.

Canva

What if you could iterate on visual content from right within Slack? The Canva Slack app is perfectly suited for those #design and #brainstorming Slack channels where visuals are more powerful than text. You can quickly generate images, create flyers, or design social media posts right from the chat window.

Apart from generating AI visuals on the fly, Canva's Slack integration includes tons of collaboration features: you can receive notifications when your design is updated, reply to Canva comments and @mentions, and even change permissions directly within Slack so others can access your Canva designs.

Les meilleures appli Slack pour l’engagement et le renforcement de l’esprit d’équipe

Digital workspaces require as much team building as in-person ones, if not more. The key is to focus on the small stuff: every tiny interaction that happens across a workday has an impact on that amorphous thing we call "company culture." Slack apps can nurture the kind of interactions you want, helping you turn a collection of remote individuals into a close-knit community.

Karma

Within some organizations, recognition has a way of just… not happening until certain calendar-imposed milestones, like an end-of-quarter event or an annual team retreat. With Karma, it's so easy to give colleagues recognition that it's hard not to do it. All you need to do from within Slack is @mention your colleagues like you normally would, then append "++" to their username along with a comment. They'll get an instant recognition that you valued their contribution, plus Karma points that can be used for things like Amazon Gift Cards.

Polly

The time-honored Slack convention for making basic decisions as a group is to add a few emojis to your post—each representing an option—and instruct your team to click the option they want to "vote" for. This works well for, say, choosing between burgers and sushi, but it's too lightweight for bigger team decisions. Polly takes team engagement a step further by allowing for more complex surveys and polls, complete with analytics and insights. You can use Polly to measure team sentiment, conduct stand-ups or regular check-ins, or even run fun quizzes to break the monotony of the workday.

Donut

Donut pairs team members for virtual coffee breaks, lunches, or mentorship sessions, encouraging casual intros and connections that might not happen in the usual course of work (especially if you're working remotely). Donut can also spark fun watercooler conversations, send celebration messages, and allow your team to give virtual recognition to colleagues. And if you make heavy use of Slack for HR, Donut systematizes those interactions by letting you enroll employees in prebuilt Slack "Journeys" with scheduled touchpoints for processes like onboarding, training, events, and offboarding.

Les meilleures appli Slack pour s’amuser

As Jack Nicholson's character in The Shining typed obsessively as he was teetering on the brink of sanity: "All work and no play makes Jack a dull boy." If that's not the kind of remote culture you're looking for, install some Slack apps for the pure fun of it, from trivia to GIF apps where you can—what else?—embed memes from The Shining.

Tacos & Trivia

How could you not have fun with an app called Tacos & Trivia? You can launch quick two-player games like Rock Paper Scissors, run icebreakers for groups, or challenge your team to weekly movie trivia. Best of all, there's a leaderboard, so you get bragging rights for winning week after week. And yes, there's a real purpose to justify all this revelry as a business expense: it'll help your team feel closer, especially if you're working remotely.

BirthdayBot

Celebrating your team members' birthdays remotely can be hard. BirthdayBot makes it easier: it automatically notifies your team about upcoming birthdays and work anniversaries, then posts celebratory messages in a team channel. It's expanded beyond birthdays—it now offers peer recognition and gift cards, too—but it's still the best, simplest way to make sure everyone on your team gets a virtual card and a stream of messages on their special day.

GIPHY

Everyone loves a good GIF. Let's thank our lucky stars that they're considered appropriate for professional settings, because without them, your workplace chat would be one dreary slab of project updates after another. Thankfully, the GIPHY Slack app brings animated GIFs into your Slack channels. To post one, just use the /giphy slash command and click "Shuffle" until you find the GIF that perfectly captures your mood. When you set up your GIPHY integration, you can choose whether to allow risqué GIFs or not by selecting from a set of movie-style ratings (G, PG, PG-13, R).

Créez votre propre robot Slack

You'll probably find the apps you need in Slack's massive app directory. But sometimes you need something a little more bespoke. That's where the magic of Zapier comes into play, allowing you to build your own customizable Slack bot.

With Zapier, you can create a Slack bot that does exactly what you need, the way you need it done. Imagine a bot that can pull analytics from your sales platform into a Slack channel every morning, or one that automatically organizes project submissions into a shared folder and notifies the team via Slack.

Or, if you're already working in an AI assistant like Claude or ChatGPT, Zapier MCP lets your AI take action in Slack—and across 9,000+ other apps—without you ever leaving the chat window.
