LobeChat vs Synthesia
A side-by-side editorial comparison of LobeChat and Synthesia — release velocity, themes, recent moves, and the top alternatives to consider.
LobeChat vs Synthesia: at a glance
What is LobeChat?
LobeHub canary.7 runs Codex on users' own devices and turns tasks into a kanban board.
LobeChat, now shipping as LobeHub, is an agent workspace built around goals, tasks, devices and projects. canary.7 bundles 75 commits: Codex app-server runs on connected devices behind a Labs flag, a task board with Kanban-column creation, archiving and command-menu search, and sub-agents relayed through the parent's executor. It also migrates the UI to @lobehub/ui 6 and drops antd entirely.
What is Synthesia?
Synthesia is becoming a general AI video editor — avatars are now one feature, not the product.
Synthesia has spent the last six months extending its product surface well beyond AI avatar generation. The Editor now ingests external screen recordings (MP4 → transcribed, scene-split, editable Synthesia video), accepts .pptx with speaker notes as voiceover, and runs an AI Playground that exposes third-party models — Sora 2, Veo 3.1, FLUX.2, Nanobanana Pro — directly inside the canvas. Avatar capability also broadened: action-taking stock avatars with arbitrary backgrounds, speech regeneration, and per-voice speed control. The release cadence has slowed visibly since March, with no public updates in the past two months.

LobeChat
6.3AI-ASSISTANTS
LobeHub canary.7 runs Codex on users' own devices and turns tasks into a kanban board.
◆ Current state
LobeChat, now shipping as LobeHub, is an agent workspace built around goals, tasks, devices and projects. canary.7 bundles 75 commits: Codex app-server runs on connected devices behind a Labs flag, a task board with Kanban-column creation, archiving and command-menu search, and sub-agents relayed through the parent's executor. It also migrates the UI to @lobehub/ui 6 and drops antd entirely.
◆ Where it's heading
Each canary moves more execution off the chat window and onto user devices and background runs: Computer Use in canary.4, shared workspace devices in canary.5, the device-model relay in canary.6, and now third-party coding agents like Codex and OpenCode running on those devices. Tasks are becoming the primary unit of work, with a board, priorities and agent assignees. A new linear_connections table suggests external issue trackers are next to plug into that task layer.
◆ Prediction
v2.2.20 stable will likely roll up canaries 4 through 7, much as v2.2.19 did; a Linear integration surfacing in the task board is the most visible next step the commits point to.
Synthesia
0.0AI-ASSISTANTS
Synthesia is becoming a general AI video editor — avatars are now one feature, not the product.
◆ Current state
Synthesia has spent the last six months extending its product surface well beyond AI avatar generation. The Editor now ingests external screen recordings (MP4 → transcribed, scene-split, editable Synthesia video), accepts .pptx with speaker notes as voiceover, and runs an AI Playground that exposes third-party models — Sora 2, Veo 3.1, FLUX.2, Nanobanana Pro — directly inside the canvas. Avatar capability also broadened: action-taking stock avatars with arbitrary backgrounds, speech regeneration, and per-voice speed control. The release cadence has slowed visibly since March, with no public updates in the past two months.
◆ Where it's heading
The strategic move is from 'create a video by typing a script for an avatar' to 'turn any input (slides, recordings, prompts) into a Synthesia-editable video,' with third-party genAI models embedded in the canvas. Avatars are repositioning as one input among many, not the headline. The pause in release cadence since March is notable for a product that was shipping every two to three weeks through Q4 2025 — could indicate a larger release in flight, a strategic reorientation, or commercial pressure squeezing the public-facing tempo.
◆ Prediction
The next visible release will likely be the next-generation avatar tier (the action-taking stock avatars were called 'one of the most exciting updates of the year' in November, so an upgrade or open-prompt avatar variant is overdue), or a foundational change to the ingestion pipeline that ties the screen-recording and PowerPoint surfaces into a single 'video from anything' flow. If the silence continues past Q2, that's a signal worth watching.
