AdHarbor is the free all-in-one AI marketing suite: ad copy, social posts, captions, hashtags, emails and ad creatives — generated from a single brief. Unlimited. No credits, no card, no account.
Free with your own Gemini key · No sign-up · Runs entirely in your browser
Predis.ai makes you generate ad copy, captions and creatives in separate flows — and charges credits for each one. AdHarbor does it in one pass.
Product, audience, offer, tone. Thirty seconds. Your Brand Voice — tone, banned words, hooks that worked — is applied automatically.
Ad copy for Meta, Google, TikTok and LinkedIn, social captions, hashtags, an email and a product description — all at once, in your brand voice.
Pick one of 20+ templates in the Creative Studio, drop in your photo or a free stock photo, export a PNG at the exact size each platform wants.
Drop kits into the content calendar, then export captions as CSV, the calendar as an ICS file and creatives as PNGs. Post from your phone in seconds.
Everything a small brand needs to market every day — without a $32–$249/month subscription.
Three Meta variants, three Google headlines + descriptions, three TikTok hooks, two LinkedIn posts — written for the platform, not copied across it.
Open Studio →Four ready-to-post captions in your tone, plus 12 hashtags matched to your niche — no more generic #love #instagood filler.
Open Studio →Three subject lines plus a full email body. Predis.ai does not do email at all — AdHarbor writes it from the same brief, free.
Open Studio →20+ editable templates — sale, launch, quote, product, testimonial and more. Brand kit, your photos, free stock, exact-size PNG export.
Open Creative Studio →Tone, audience, banned words and winning hooks saved in your browser and applied to every generation. Jasper and Copy.ai charge $69–$1,000/month for this.
Set your voice →Plan a week or a month from your saved kits. Export CSV captions, an ICS calendar and a PNG bundle — the honest substitute for auto-posting.
Open Calendar →Predis.ai is the closest all-in-one tool — and the model for this suite. Prices verified live on predis.ai/pricing, 28 Oct 2026. The difference is the meter.

What AdHarbor deliberately does not do: AI video, auto-posting, competitor analysis and predictive scoring. Those need servers, account connections and proprietary spend data — a free static app cannot honestly offer them, so it does not pretend to.
Across Jasper, Copy.ai, AdCreative.ai and Predis.ai, the #1 complaint is not the product — it is the billing: credit caps, card-required trials, charges after cancellation, surprise annual bills. AdHarbor removes the meter entirely.
Yes. There is no paid plan, no account and no card. You bring your own free Gemini API key (free from Google AI Studio, no card required) and AdHarbor generates as much as you want — no credits, no monthly meter.
Predis.ai charges $32 to $249 a month, rations every generation with credits, and requires a card for its 3-day trial. AdHarbor does the same core jobs — ad copy, social posts, captions, hashtags, ad creatives — free and unlimited, and adds email copy and product descriptions in the same brief, which Predis does not cover.
No — auto-posting needs a server and account connections, and AdHarbor is a static app with no server. Instead you plan in the built-in content calendar and export captions as CSV, the calendar as an ICS file, and creatives as PNGs, then post from your phone or scheduler in seconds.
No. AI video and AI image generation need paid GPU services — Gemini image models are paid-only and have no free tier. AdHarbor generates text with your free Gemini key and renders ad creatives on a canvas from templates, your photos and free stock photos, which is genuinely free.
Your key is stored only in your browser's localStorage and is sent directly from your browser to Google's Gemini API. It is never stored on any server — AdHarbor has no server at all — and never leaves your device except to call Google.
It does not do AI video or avatars, auto-posting, competitor analysis, or predictive performance scoring. Those need servers and proprietary data. AdHarbor is honest about that and wins on creation: one brief, a full campaign kit, unlimited.
One brief. A full campaign kit. Free, unlimited, yours.
