In-depth Report

Copresent is a Chrome extension designed for Google Slides that turns any phone into a slide remote control and supports up to 10 people to collaborate on presentations through a link. Its core difference lies in the zero-threshold guest appearance - guests do not need to install any software or register an account, they can just open the browser to participate in page turning and note viewing. It received 123 votes and 22 comments on the first day it was launched on Product Hunt in July 2026. It is currently rapidly gaining attention in education, sales and team reporting scenarios.

Copresent is developed by a team based in Sydney, Australia, and officially launched on Product Hunt in mid-July 2026. The product is positioned as a lightweight collaboration tool in the Google Slides ecosystem. It solves the most common pain points: the speaker is tied to the computer, and the embarrassing scene of frequently saying "Thank you for the next slide" during multi-person presentations. According to information from the Chrome Web Store, the current version of this extension is 1.6.1, which was updated on July 9, 2026. It is only 388KiB in size and is an extremely lightweight tool. Developer email hello@copresent.app, official website copresent.app. This product is not a financing-driven AI startup project, but more like an efficiency tool for specific usage scenarios - there is no complex business model, no money-burning customer acquisition strategy, and the product itself is the value carrier.

Copresent provides three levels of functionality around the core concept of “making presentations more free”: Mobile phone remote control. Hosts only need to install the extension once in Chrome, open Google Slides and click the Copresent button to generate a unique link. Open this link on your mobile phone and you will get a mobile remote control interface: slide left and right to turn pages, and the mobile screen will simultaneously display the current slide and speaker notes. The whole process takes less than 30 seconds and requires no Bluetooth pairing, QR code scanning, or app installation. Multi-person collaborative control. This is the core differentiating function of Copresent. Share the same link with others and up to 10 people can control the same presentation at the same time. Every participant can turn pages and see notes, whether on a mobile phone or computer. This means that during team roadshows, members can each control their own chapters, without the need to switch back and forth for screen sharing, and say goodbye to rhythm-interrupting verbal handovers such as "Trouble with the next one." Privacy by design. Each presentation generates an independent and unique link, and the host can generate a new link at any time to invalidate the old link. Slides always stay in Google Slides and Copresent does not store or upload presentation files. This is important for corporate clients and student projects that require confidentiality. In actual use, the common feedback from users is that "multiple people can control the field by sharing the link", "turning pages directly without installing the app" and "floating notes is very practical". A user on Product Hunt mentioned in a comment that it only took a minute from installation to controlling it with a mobile phone, and the "no account link" was the most satisfying part.

Copresent's current core functionality is completely free. There is no tiered pricing and no free version restrictions. This is a smart but risky choice for a product that has just been launched: the smart thing is that it can quickly win over users and accumulate reputation, but the risk is that it takes time to find a sustainable path to monetization. The current product does not display any paid plans or trial period prompts, and the target user group can use all functions at zero cost.

Due to the short launch time of the product, public user reviews are mainly concentrated in Product Hunt and some Chinese technology reports. Reviews from Product Hunt are generally positive, emphasizing "extremely fast setup", "smooth multi-person collaboration" and "good page-turning experience on mobile phones". In a discussion in Reddit's education section, one user recommended Copresent as a "solution that stays within Google Slides," but also pointed out that managed school computers may block Chrome extensions, which is a real problem for education scenarios - if a student's Chromebook is restricted by IT policy from installing extensions, Copresent is only useful for the teacher side. The Chinese community’s focus is more on “zero threshold”. Sheepnav, a domestic efficiency tool evaluation website, gave a positive review, emphasizing that the product "does not require downloading the app or registering an account, just open the browser to start the presentation." Some comments pointed out that it can currently only be used for Google Slides and is not suitable for PowerPoint and Keynote users.

From an industry perspective, Copresent is entering an area that seems crowded but actually still has gaps. There is no shortage of slide remote control tools on the market, such as Pear Deck, Slides Companion, and various Bluetooth page turners, but these products are either too feature-heavy (Pear Deck is more focused on classroom interaction rather than remote control), require hardware (traditional page turners require additional purchase and carrying), or rely on specific conferencing platforms (Google Meet's collaborative presentation requires editing permissions and does not support mobile phones). The unique positioning of Copresent is that it does not create and beautify presentations, only the "control layer". In the Google Slides ecosystem, it is equivalent to a shared remote control - different people can take turns operating the same document without switching devices. This minimalist positioning gives it a clearer differentiation. In 2026, when AI presentation tools are developing rapidly, many products are developing automatic slide generation, AI layout, and intelligent summary of content. Instead, Copresent has chosen a more traditional but solid path: to achieve the ultimate in presentation control. This choice seems scarce in the current market environment.

The main limitation of Copresent right now is platform binding. It only supports Google Slides, and the host must be running the Chrome browser and have the extension installed. For heavy PowerPoint and Keynote users, this product currently offers no value. From a security perspective, although the design of shared links is convenient, there is also a certain risk - the person who gets the link can control the demonstration. Although the host can generate new links to revoke old links at any time, link management requires additional attention in the context of large events. In terms of permissions, the Chrome extension requests access to Google Docs pages and the Copresent API, as well as identity and storage permissions. Security-sensitive organizations will need to review current privacy policies and permission statements before approving use. Network dependency is also a real issue. All instructions are transmitted through the Internet, and delays or disconnections may occur in environments with unstable networks (such as underground conference rooms, large exhibition sites). Finally, the product is still very early. There is currently no large user base to verify its stability and long-term reliability, and there is no clear after-sales support channel.

Copresent is best suited for four types of users: Educators. Teachers can leave the podium during class, use their mobile phones to control courseware, and move around the classroom at the same time, paying attention to students' reactions at any time. Teaching assistants or students can also control courseware through links, which is suitable for group presentation. Sales and Account Team. During client proposals or quarterly reports, different members can each control their own parts without having to plug in and unplug computers or pass around page turners. Student groups. In scenarios such as graduation defense, project presentations, and entrepreneurial road shows, multiple members can take turns controlling the field through their respective devices. Online event host. In a webinar or online meeting, multiple presenters can take turns controlling the same presentation from their own devices without having to switch back and forth between screen shares. These users need to pay attention before using it: confirm that the host computer allows the installation of Chrome extensions, test it in advance under actual device and network conditions, and the link will only be shared with those who participated in the demonstration and will be invalidated after the end. If the team primarily uses PowerPoint or Keynote, or the presentation environment is completely off-line, Copresent is not a good fit.

Copresent is a Google Slides collaboration tool with precise positioning and restrained design. It did not chase the AI craze, but delved into the specific scenario of "demonstration control" and solved a common and long-lasting pain point in the lightest way. For serious Google Slides users, it's free, non-intrusive, and works out of the box, making it worth a try. But its platform bindings and early stage also mean that it's far from a general-purpose presentation solution.
