FAQ

FAQ

Common questions and practical answers.

The AI Agent publishes to major social networks via the Late API. It supports Facebook, Instagram, LinkedIn, and TikTok when the corresponding accounts are enabled. You can add or remove platforms in the Default Settings. The system adapts copy length and visuals to each platform's constraints. Publishing is done through authenticated API calls, ensuring reliable dispatch.

Yes. Gemini can tailor copy length to each platform, and you can specify tone preferences as part of the configuration. If a network requires shorter text, the agent trims accordingly or expands with a follow-up variant. You can adjust these settings before running the workflow. The fallback content is used if Gemini cannot parse properly.

Typically a run completes within a few minutes, depending on asset size and network constraints. Copy generation and image design occur in parallel to save time. Uploading to Late and publishing are batched to minimize API calls. The exact duration scales with media size and platform count.

Fallback content is included to ensure the workflow continues. If Gemini output is unusable, the system reuses previous templates or prompts to generate valid alternatives. You can review and re-run specific sections without restarting the entire AI Agent. Notifications still trigger for transparency.

Assets are uploaded to Late via its upload API and stored according to the platform mappings. The workflow keeps track of asset IDs and post IDs for auditing. Redundant uploads are avoided by using the multipart flow for large files. Access controls follow your credentials setup.

Yes. You can run a test publish with a limited subset of platforms or use a dry-run mode to validate copy, visuals, and mappings. The agent logs the results and provides a preview of each platform’s post. This minimizes risk before live publishing.

Costs depend on the services used (Gemini, Seedream, Late API) and your plan. The AI Agent itself orchestrates calls to these services; you pay per API usage. Some platforms offer free tiers, and there are charges per post that vary with media size and number of platforms. You can estimate costs from your provider plans.
