SemChat comparison: which SEO tool fits your site?

This SemChat comparison isn’t looking for “the best SEO tool”. It’s looking for the right tool for your need. You have a site, little time, and you want people to find it: that’s not the same choice as an agency tracking thirty clients.

Each tool has its own detailed head-to-head, linked below. Here you get the big picture, so you know which one to open. If you’d rather see what you can do without paying first, our guide to the best free seo tools sorts them by need.

The short answer: one tool per need

1. You want a plain answer without learning a tool: SemChat, Free plan at €0, then €20 a month.
2. You run several sites or countries: Semrush, from €134 a month, 142 country databases.
3. You want a large worldwide link and keyword database: Ahrefs, from €27 a month before tax, without its assistant.
4. You’re an agency tracking rankings every day: SE Ranking, from €109 a month.
5. You want a low-cost data tool: Ubersuggest, from €29 a month.
6. You write a lot of content: Surfer, from €59 a month before tax.
7. You want to publish to WordPress from a chat: ChatSEO, from €29 a month before tax.
8. Your market is France and you like digging into data: Haloscan, from €59 a month before tax.

Monthly entry prices as each official site showed them from France, in euros, on 29 October 2026 (30 October for SemChat). Prices shown to US visitors may differ.

How I compared them

1. Only one tool tested for real: SemChat, on my site plugkit-avis.com, on 29 October 2026. It’s all in my SemChat review.
2. The others on their official pages: pricing, home and help pages, read on 29 October 2026. A feature that isn’t mentioned stays “not mentioned”.
3. Three criteria: entry price, free plan, and how you work (tables or conversation).
4. One reader: someone who wants to be found online, not an SEO consultant.

The full suites: Semrush, Ahrefs, SE Ranking

These three cover many countries and many features. Their prices follow.

Semrush lists 142 country databases and daily rank tracking from its SEO plan at €134 a month. Its Free plan gives 1 project and 10 reports a day. You can chat with it from ChatGPT, Claude or Perplexity through its MCP server, shown from the Starter plan at €190 a month. The details: Semrush vs SemChat.

Ahrefs claims “217+” countries and locations covered. Its Free plan works for your own verified sites. Starter costs €27 a month before tax, billed monthly only; its Ask Ahrefs assistant needs Lite, at €119 a month before tax. The details: Ahrefs vs SemChat.

SE Ranking tracks 2,000 keywords a day from its Core plan, at €109 a month, on a 188-country database. It says it has no permanent free plan, but offers a 14-day trial with no card. The details: SE Ranking vs SemChat.

Low-cost data tools: Ubersuggest, Haloscan

Ubersuggest starts at €29 a month (Individual). Its free plan allows 3 searches a day, and its MCP server also works with a free account. The 7-day trial of the paid plans asks for a card. The details: Ubersuggest vs SemChat.

Haloscan comes from the same company as SemChat, ARCHI301, and supplies its data in France. It has a Free plan, then Starter at €59 a month before tax, API included. Its data covers the French market only, so it doesn’t fit a US site. The details: SemChat vs Haloscan.

Assistants and writing: ChatSEO, Surfer

ChatSEO also works by conversation. It has no free plan, but a 7-day trial with 30 credits. Starter costs €29 a month before tax for 100 messages. It publishes to WordPress and offers an MCP server with 38 tools from the Pro plan, at €49 before tax. The details: ChatSEO vs SemChat.

Surfer is for writing: its editor scores each text against Google’s top 10. It describes itself as “Not a chatbot or a general-purpose AI assistant”. Its pricing page shows no free plan; Discovery costs €59 a month before tax.

Where SemChat fits

SemChat is an assistant: you type your question, it runs its tools and gives you an action plan. On 29 October 2026, one sentence was enough to get 8 indicators, a 5-point diagnosis and 3 actions for the week, in about 3 minutes.

Its four plans have the same features: Free at €0, Starter at €20 a month, Pro 5x at €100, Pro 20x at €200. The details are on the SemChat pricing page. The limit to know: my first audit used up the Free plan’s quota.

Where SemChat isn’t the right pick

• You track many sites or clients: suites like Semrush or SE Ranking are built for that, reports and daily tracking included.
• You want to track your presence in ChatGPT or Gemini today: Semrush, Ahrefs and Surfer offer it; at SemChat it’s announced as planned, with no date (e-mail from Haloscan, 29 October 2026).
• You want to check every number yourself: a data tool like Ubersuggest shows you the raw tables.

For everything else, and especially if you’re starting out, this SemChat comparison leans toward the assistant: one question in plain words, an action plan, and a Free plan to try it.
