“My site is stuck on page 2. What should I fix first?”
Claude · anthropic
Your internal links spread the authority too thin. I would start there.
GPT · openai
True, but your titles miss the search intent. Fix the click-through rate first.
Summary from the lead model
Link to your money pages first, then rewrite the titles around the intent.

01The tools
Twelve tools. An expert method behind each one.
-
Expert Chat Multi-model · Your data
A web consultant that adapts to your question. Add more models so they debate and settle on a summary, import your Semrush, Search Console and Haloscan exports, or connect a WordPress site. It then acts on the site (fixes image alt text, creates pages and more) once you confirm.
-
Site audit Deliverable · PDF
Technical, on-page, content, performance, E-E-A-T, accessibility and internal links. Pick the checks you want, including Google Discover readiness and AdSense approval readiness. You get a full audit, prioritized and tailored to your type of site, delivered as a PDF ready to present.
-
Auto-blog Studio · Automatic publishing
Your site publishes on its own. Enter your keywords, approve the optimized titles the AI suggests and pick a schedule. Each article is written, illustrated and published on your WordPress site, even with your browser closed. Part of the Studio plan, with unlimited articles and sites.
-
Article writer SERP analysis + writing
One keyword is enough. The tool studies the three pages that rank, then writes an article designed to cover the topic better than they do, in a natural voice with no AI tells. You get a full editor, HTML and Word export, or direct publishing to WordPress with featured image, in-body images with alt text, SEO meta and draft, published or scheduled status.
-
Image generator Guided prompt · Discover
Build the right prompt (style, framing, light, colors, quality), generate the image with your OpenAI or Google key, switch on the Discover-friendly mode and download it in full quality.
-
Website builder ZIP ready to deploy
A ready-made lead generation site (3 designs, local SEO, contact form), built inside your browser and delivered as a ZIP you can put online with any web host.
-
Lead magnet generator Ebook PDF & Word
Describe a niche. You get a custom outline, then a full ebook of 10 to 100 pages, written in a human voice and laid out with callout boxes. Every ebook is unique. Export to PDF and Word, with a cover made in the image tool.
-
SEO research Real data · DataForSEO
Real search volumes, difficulty, intent, CPC and keyword ideas, pulled with your DataForSEO key in direct calls that never touch our servers. Spot the keywords with the most potential, group them by intent, then start an article or export them in one click. No number is ever made up.
-
Internal linking Interactive graph · Topic clusters
Maps every internal link of your WordPress site as an interactive graph. It finds orphan pages and pillar pages, works out a linking plan and a topic cluster, then creates the missing links and articles in one click. Everything runs on your key and nothing passes through OpenTahr.
-
Indexing URL Inspection · SpeedyIndex
Finds the published pages Google does not index and the reason for each one (crawled but not indexed, duplicate, noindex and so on), then hands each page to Expert Chat for the right fix. You can also submit pages to SpeedyIndex with your own key and pay SpeedyIndex per result. Send one page in a click, all non-indexed pages at once, or a pasted list of URLs from any site. SpeedyIndex speeds up crawling but cannot guarantee indexing. It works through your Search Console and the OpenTahr plugin, so nothing passes through OpenTahr.
-
Link building BYOK · LemmiLink
Build the authority of your pages with relevant backlinks. Choose the URLs you want to push, order campaigns through your LemmiLink account without leaving the workshop and follow their progress. With your own key, you pay LemmiLink directly and nothing passes through OpenTahr.
-
Boost Pop BYOK · PopCash
Every time you publish an article, a PopCash pop-under campaign can start on its own. You get full targeting (country, device, browser, OS, traffic category), a budget per article, presets you can reuse across sites in one click and a dashboard. With your PopCash key, you pay PopCash and the campaign starts from your WordPress server, so nothing passes through OpenTahr. Each new campaign goes through PopCash review first (submitted, then live).
02How it's free
Why it's free, with no catch.
Everything runs on your side
The tools run in your browser. There is no server farm to pay for, so there is nothing to bill you for the core features.
Paid plans stay optional
The free version already covers eleven of the twelve tools, with unlimited articles, images and chat on one site. Pro moves you to 5 sites and removes the OpenTahr credit from exports. Studio makes everything unlimited, sites included, and adds the auto-blog and bulk generation. The core stays free and your keys stay yours.
03How it works
Three steps. Nothing in the way.
Connect your keys
One OpenRouter key gives you every model. It is stored on your device and nowhere else.
Pick a tool
Expert chat, audit, generation, internal linking. Each tool follows an expert method built around the result.
Leave with a deliverable
A PDF, a website, a report. Something you can use or present to a client, more than a block of text.
04Trust by default
Your keys stay with you. Period.
OpenTahr runs in your browser. Your API keys are stored locally and never pass through our servers. We can't see them, lose them or sell them, because we never receive them.

06Questions
Frequently asked questions.
Is OpenTahr really free?
Yes. You use your own API keys, so you only pay for your AI usage, directly to the provider. OpenTahr takes nothing on that usage. Every account is free during the beta. Once paid plans launch, the free plan keeps eleven of the twelve tools (the auto-blog is part of Studio), with unlimited articles, images, chat and SEO research on one site.
What is the difference between the plans?
Free gives you eleven of the twelve tools with unlimited articles, images, chat and SEO research on one site, plus 2 audits and 1 ebook a month, and exports that carry a “Powered by OpenTahr” credit. Pro (€29.99/month, €199/year to save 45% or €599 lifetime) moves you to 5 sites, adds 30 audits and 30 ebooks a month and removes the credit. Studio (€99/month, €799/year to save 33% or €1,499 lifetime) makes everything unlimited, sites included, and adds bulk generation. There is no rank tracking or monitoring, because OpenTahr is built to create and audit rather than to watch.
Are my API keys safe?
They never leave your browser. No key is stored on our servers and every call goes straight from your device to the provider.
Can I publish straight to WordPress?
Yes. Install the free OpenTahr Connector plugin on your site, create a connection key and connect the site in OpenTahr. You can then publish your articles and images (with optimized alt text and SEO fields) in one click, as a draft, live or scheduled. The connection is secure (hashed key, HTTPS, access limited to OpenTahr) and nothing passes through our servers, since every action goes from your browser to your site. The Studio plan adds the auto-blog, which publishes on a schedule.
Which models can I use?
All the major models (Claude, GPT, Gemini, DeepSeek, Mistral, Qwen and more) with a single OpenRouter key, or with your native keys for each provider.
Do I need an account?
Yes, a free account gives you access to your workspace and your tools. The account stores your email and your preferences, never your keys.
Why a tahr?
The tahr climbs where nobody else goes. That is the whole idea, helping your sites climb higher than the competition.
