You see a bug on a staging page. With Gyazo you hit the shortcut, a URL lands on your clipboard, and you paste it into chat. Done in two seconds. That speed is the whole appeal, and for a one-off "look at this" it is hard to beat.
The trouble starts after you paste the link. The screenshot sits there, and the conversation about it happens somewhere else: a Slack thread, a DM, a ticket you file later. The image and the discussion drift apart. Three days on, nobody can tell you which of five near-identical shots got fixed and which are still open.
What Gyazo is built to do
Gyazo captures a region or a window and hands you a hosted link fast. You can annotate on the paid tier, organize captures into collections, and search your history. If your job is to grab an image and drop it into a conversation, it does that cleanly and quickly.
What it does not try to be is a place where feedback lives and gets closed out. A Gyazo link is a picture at a URL. The reply, the follow-up question, and the "fixed in build 44" note all happen outside it. That is not a flaw. It is a different job. A quick share and a trackable review are two separate things, and picking the right one depends on what happens after you hit send.
Where a review link changes the shape of the work
Cobalt Capture also runs in a browser tab with no install and no extension, and it also gives you a short link to paste. The difference is what rides along with the link. A review is a list of items, each one a screenshot you have cropped, pinned, and marked up, with a comment you typed or dictated. On Publish it becomes a page anyone can open without logging in, at a /r/<slug> address, plus a reader-only /s/<slug> view for people who only need to read.
The part that matters here: people with the link can comment on any individual item, and the owner can mark each comment resolved. The feedback and the conversation about it stay in the same place. You can see at a glance which items are closed and which are not, without a separate tracker. If you have ever lost track of a Gyazo shot in a Slack scroll, you can close out review comments without a bug tracker instead.
The dimensions that decide it
| Dimension | Gyazo quick shot | Cobalt review link |
|---|---|---|
| Time to first share | About a second, clipboard URL | A few seconds longer: capture, mark up, publish |
| Install | App or extension depending on platform | None, runs in a browser tab |
| Comments on the shot | Happen elsewhere | On each item, in the link |
| Resolution state | Not tracked | Owner marks each comment resolved |
| Export formats | Image | PDF, Word, HTML, and clean markdown |
If your need is genuinely one image and one sentence of chat, the extra structure is overhead you do not want. Grab the shot and move on. Cobalt does not win that race, and pretending otherwise would waste your time.
When the thread is the point
The review link earns its keep the moment more than one person reacts to the same screen, or the same screen comes back for a second round. Client work is the clear case: you send a build, the client marks up three screens, you fix two and reply on the third, and the whole exchange stays on one page. That is the flow behind client feedback without making anyone learn a tool.
It also matters when the receiver is a developer or a coding agent. The same review is available as plain markdown at /r/<slug>/markdown, and an AI assistant that opens the link is served that markdown automatically. Numbered pins and arrows are baked into the exported images, so whoever reads the export sees exactly what you marked. A signed-in owner can also send a review to a GitHub repository as an issue. None of that comes from a plain hosted image.
The honest tradeoffs
Cobalt is not a screen recorder; it captures still frames, not video. It does not draw on the live page, so your markings go on the captured still. It is not a bug tracker with assignees and workflow states; resolved-or-not is as far as the status goes. On a phone the browser cannot capture the screen, so you take a normal screenshot and add it. And there is no multi-reviewer live session.
On pricing, the whole thing is this: unlimited reviews with no password or card, and after 7 days a review goes read-only for you, meaning editing, exports, and agent access stop while the shared link keeps working for everyone you sent it to. Pro removes the cutoff at $5 a month or $50 a year, cancellable any time. Full detail is on the pricing page. For a fuller side-by-side of the two flows, the quick share versus review link comparison walks through more cases.
Pick by what happens after you send. One shot into a chat: a quick-share tool is the right call. Feedback that needs replies, rounds, and a clear done state: start a review link and keep the conversation attached to the thing it is about.
