What is OpenAdKit?

OpenAdKit is the open source AI marketing tool that replaces a $49–$499/month stack of paid AI marketing tools (Jasper · AdCreative · Anyword · Pencil · Copy.ai · Marpipe) with one app that runs entirely in your browser.

You bring your own AI key — free-tier (Groq · Gemini · Cerebras · OpenRouter) or paid (Claude · GPT · Mistral · DeepSeek) — and get every paid-tool feature for $0/month, forever.

18 AI generators · 11 data-driven optimizers · 9 AI providers · multi-client brand brains · vision (image) input on Claude/GPT/Gemini · platform-grouped sidebar · 10-minute launch wizard · multi-client batch mode · auto-update from GitHub.

Use it for: writing Google Ads RSA copy, generating Meta / Facebook / Instagram / TikTok / LinkedIn / YouTube / X ads, building Reel hooks, scoring creatives before launch, fixing low-CTR ads, planning campaigns end-to-end, running an agency across many clients, or teaching yourself paid media via the built-in framework trainer (PAS · AIDA · BAB · 4 U's · Schwartz awareness ladder).

How to use OpenAdKit — step-by-step

Your first 10 minutes from install to your first AI-generated ad. Follow these five sections in order; total time is about 10 minutes.

Step 1 · Get OpenAdKit running (30 seconds — 5 minutes)

Pick one of the two install paths:

• Path A — Hosted (recommended for non-developers). Click the Deploy with Vercel or Deploy to Cloudflare button in the Install in 60 seconds section above. Sign in to Vercel/Cloudflare with GitHub, confirm, get your own URL in 30 seconds. Open the URL in your browser. Done.
• Path B — Local install. Download the repo as a ZIP (green "Code" button → "Download ZIP") and extract it. On Windows double-click OpenAdKit.bat; on Mac/Linux double-click OpenAdKit.command. First run installs dependencies (one-time, ~2 minutes), drops a desktop shortcut, and opens the app in your default browser. From the second launch onwards it's a single double-click → browser opens to the app.

You'll know it worked when the OpenAdKit setup wizard loads in your browser (see screenshot #1 above).

Step 2 · Pick an AI provider + paste a key (2 minutes)

This is the only paid thing in OpenAdKit, and it can be $0 if you pick a free tier.

1. The setup wizard shows all 9 supported AI providers grouped by Free (Groq, Gemini, Cerebras, OpenRouter) and Paid (Anthropic Claude, OpenAI GPT, DeepSeek, Mistral, Together AI).
2. Recommended for first-timers:
   • Groq (free, fastest) — sign up at console.groq.com, copy your API key (starts with gsk_…), paste in OpenAdKit.
   • Gemini (free, great quality) — get a key at aistudio.google.com, paste it.
   • Claude (best quality, paid) — get a key at console.anthropic.com, starts with sk-ant-….
3. Click Verify — OpenAdKit makes one tiny test call to confirm the key works.
4. Pick a model from the dropdown (defaults are sensible). Click Continue.

💡 You can add multiple provider keys and switch between them anytime in Settings — useful when you hit a free-tier rate limit, just one-click swap to another provider.

Which AI gives the most free credits? (built into the app at /providers)

Not sure which provider to pick? OpenAdKit ships a "Which AI should I use?" page that compares every provider's free tier, real cost per generation, and image support side by side — and adds a measured column from your own usage.

Best free option for volume: Groq — 14,400 requests/day with no credit card. Watch out for Gemini: its free limits are counted per model, and gemini-3.6-flash allows only about 20 requests/day — the Flash-Lite models are far more generous. These are measured and published figures, not estimates.

On "which AI writes better ads": we don't claim to know, and neither should anyone else. There is no ground truth for ad copy, so a quality ranking would be invented. What the app does instead is measure retry rate — how often a provider's first reply failed schema validation and had to be re-asked. That is observable, it doubles your token cost when it happens, and it is computed from your own generation history.

Step 3 · Add your first brand (3 minutes)

This is OpenAdKit's killer feature. You paste one URL, the AI extracts a complete brand profile in 30 seconds.

1. The setup wizard's last step asks for a website URL. Paste the URL of any brand you want to generate ads for — could be your own brand, a client's, or a competitor's you're studying.
2. Click Extract. OpenAdKit:
   • Reads the homepage (and 2–3 key subpages like /about, /pricing)
   • Pulls Open Graph data, JSON-LD schema, and social links automatically
   • Asks the AI to fill 30+ brand fields: business name, industry, niche, USP, tone, audience pain points, audience desires, key benefits, brand voice, words to use, words to avoid, competitors, and more
3. Review the populated Brand Brain. Edit anything that looks off. Hit Save.

💡 Agencies: repeat Step 3 for each client. Switch the "active client" from the top-bar dropdown anytime; every generator and optimizer automatically uses the active client's Brand Brain to keep the voice consistent.

Step 4 · Generate your first ad (1 minute)

1. From the dashboard (cockpit), pick a generator. For your first time, try Meta · Facebook + Instagram Ads — it's fast, visual, and gives three angle-distinct variants per click.
2. Fill the form:
   • Objective — what's the campaign goal (sales, leads, awareness)?
   • Format — Feed / Reels / Stories / Carousel
   • Product / offer — what are you advertising? (Pre-filled from your Brand Brain.)
   • Promotion — any offer like "20% off" or "free trial"
3. Click Generate. Watch the AI stream the output in real time.
4. You get 3 variants anchored to different psychological angles (pain, desire, social proof), each with:
   • Primary text (front-loaded for Meta's 125-char mobile preview)
   • Headline (≤27 chars mobile / ≤40 desktop)
   • Description
   • CTA button suggestion
   • Character count validation per field (the schema retry layer catches AI mistakes)
   • For video formats: hook 0–3s, value 3–15s, CTA 5s with b-roll suggestions and on-screen text

💡 Hit ⌘+↵ (Mac) or Ctrl+↵ (Windows) anywhere in the generator to regenerate without touching the mouse.

Step 5 · Score, optimize, and ship (3–5 minutes)

You've generated copy. Now use the optimizers to make sure it's actually good.

1. Copy one of your variants. Open Optimize → Creative Score from the sidebar.
2. Paste the ad copy. Pick the platform you wrote it for. Click Score.
3. You get a brutal 5-lever score (hook strength, specificity, urgency, brand fit, conversion potential), a tier verdict (scale / iterate / rewrite / kill), a predicted CTR band, and 3 named fixes — each fix names the exact phrase to change and the replacement.
4. Apply the fixes. Re-score. Repeat until your tier reads "scale" or "iterate".
5. Optionally run other optimizers before launch:
   • CTR Optimizer — lever-by-lever rewrites to lift click-through
   • Budget Waste — audit where ad spend is leaking before it does
   • Audience Targeting — turn brand brain + budget into a cold/warm/hot tier plan
   • Quality Score (Google) — surface relevance issues before they tank your QS
6. Export the campaign as Markdown or JSON for client handoff via the History page.

💡 Use Launch Guide in the sidebar for step-by-step screenshots walking you through Facebook Ads Manager or Google Ads from campaign creation to publish — useful if you're new to paid media.
