Oetzi vs Buffer: deciding what to say or publishing it

Pick Buffer if you already know what to post and want the most familiar place to queue it, including from Claude. Pick Oetzi if the hard part is deciding what to say, because Oetzi listens on seven platforms, scores the conversations worth answering, and drafts the post and the reply in your voice. A scheduler publishes what you hand it. The question is who writes the thing being handed over.

What Buffer does well

Buffer is the default for a reason. It is simple, it has been stable for years, and it does not ask you to learn a philosophy before you can queue a post. More interesting lately, Buffer publishes a guide on posting from Claude, which puts it in a small group of tools an agent can actually drive.

None of that is in dispute here. Buffer does not listen and does not claim to.

Deciding what to say against publishing what you hand it

The gap between those two jobs is where most founder marketing dies. The queue is not the problem. The empty queue is.

Oetzi works backwards from the market. Social listening across X, Reddit, LinkedIn, Threads, Bluesky, Hacker News, and Substack Notes finds people asking what to use, complaining about a competitor, or describing the problem you solve, and scores each match 0 to 100 for buying intent with the reason written out. The posting plan sets a cadence per platform and drafts one post per run from that material plus the day's trend scan. A voice doc built from your own posts keeps the drafts sounding like you, and edits and regenerations are free.

Publishing is then a solved problem rather than a product. Oetzi publishes through Postiz to its platforms at no credit cost, and auto publishing for scheduled posts exists and is off by default.

The agent story differs in kind as well. Driving Buffer from Claude means your agent hands over finished text. With Oetzi the agent can run the whole loop: sweep a signal, read scored matches, draft a reply, check share of model, publish. Every capability sits behind an MCP server, a REST API, and a CLI, with read, write, spend, and post scopes, and any paid call returns a quote and runs only with approval and a credit cap.

Pick Buffer if

• You know what you want to post and need a dependable queue, nothing more.
• You want to start free today with no decision to make.
• Your agent or your writer already produces the text and only publishing is missing.

Pick Oetzi if

• Your queue is empty more often than it is full.
• You want posts drafted from what your market actually said this week.
• You want replies to other people's conversations drafted too, held for your approval.
• You want an agent to run listening, drafting, and publishing with spend caps, not just publish.

Questions

Does Oetzi replace Buffer?

For most founders it covers the same ground, because drafting, scheduling, publishing through Postiz, and post metrics are all included and publishing itself costs no credits. If you are happy with your scheduler, keep it and use Oetzi for listening, replies, and deciding what to post. The two jobs are separable, which is why the integration path exists at all.

Can I post to Buffer from Claude?

Buffer publishes a guide on doing exactly that, so yes. What the agent cannot do through a scheduler is find the conversation worth answering, score it, or write the reply in your voice. Oetzi exposes those steps to the same agent through MCP, a REST API, and a CLI, with a quote and a credit cap on every paid call.

What does Oetzi charge for publishing?

Nothing. Publishing through Postiz, auto publishing, post metrics, the scoreboard, the daily trend scan, tracked links, and the outcomes ledger are all free. Credits go to the work that costs us money: one credit for a drafting run of one to three variants, two credits for a sweep across every platform, and two credits for a share of model question across five engines.
