Later helps you lay out a visual feed you still have to write. Sydium writes every caption in your voice and publishes across nine platforms on its own.
Later is one of the best Instagram grid planners ever built. We built Sydium for creators who outgrew the Instagram-only era and want AI that creates content, not just schedules it.
Later was the first scheduler to take Instagram grid planning seriously, going back to 2014. The grid preview and visual-first workflow are still the most polished in the category. For Instagram-heavy brands, that is real product depth.
Sydium was built for a different creator: someone whose audience is already spread across 5+ platforms (LinkedIn, TikTok, YouTube, Threads, X) and whose actual bottleneck is producing captions in their voice, not arranging the grid. Later's AI is a thin layer of caption suggestions on top of a planning tool.
Later removed its free plan in 2023. Starter is $25/month for one social set, capped at 30 posts per profile per month. If you post more than once a day to one account, that cap pushes you up the pricing ladder fast.
| Metric | Later | Sydium |
|---|---|---|
| Entry paid plan | $25/mo (Starter, 1 social set) | $28/mo (Pro, annual) |
| Free plan | No (removed 2023) | Yes (200 AI credits/mo) |
| Brand voice trained on your posts | No | Yes |
| Posts per profile cap | 30/mo (Starter) | No per-post cap on paid plans |
| Visual grid preview (Instagram) | Yes (industry leading) | Yes |

Later is genuinely strong in five specific areas. If any of these is the center of your workflow, Later is the right pick.

Yes, with an Instagram grid preview on the calendar. Later's grid is more polished after a decade of refinement. If grid planning is 80% of your workflow, Later is still the better tool for that specific job. The difference: Sydium fills the grid for you with AI-generated content.
Starter: 30 posts per profile per month. Growth: 150 posts per profile per month. Advanced and Agency: unlimited. Sydium has no per-post limits on any paid plan.
No. Later removed its free plan in 2023. You get a 14-day trial, then the cheapest option is Starter at $25/month. Sydium has a free tier with 200 AI credits per month.
Sydium Agency is $79/month (annual) with up to 20 clients, white-label reports, a client-facing portal, and approval workflows. Later's Agency plan is $200/month for 15 social sets with no white-label and no client portal. For multi-platform agencies, the gap is significant.
Yes. Later for Instagram grid planning specifically, Sydium for everything else - AI content, multi-platform publishing, analytics, unified inbox. Both tools can connect to the same Instagram account.
