SeaText on Tilda Free vs Paid Plans: Feature Matrix and Upgrade Guide
SeaText does not function on Tilda's Free plan because the Free plan blocks custom JavaScript in the <head> tag. Any paid Tilda plan (Personal or Business) allows the SeaText script to load, unlocking all...
If you are on Tilda's Free plan, SeaText simply cannot run. The Free plan does not let you paste JavaScript into the global HEAD field, which is the only way SeaText activates its autonomous agents. The moment you upgrade to any paid Tilda plan — Personal or Business — the HEAD field becomes editable, the SeaText snippet loads, and every agent (conversion optimization, 125-language translation, bot-click refunds, Google Ads keyword rewrites, ChatGPT visibility, and more) works at full capacity. There is no feature difference between Personal and Business for SeaText; the only gate is the ability to add the script.
| Criterion | Tilda Free | Tilda Personal / Business (any paid plan) |
|---|---|---|
| SeaText script injection | Blocked — no access to Site Settings → Edit code inside HEAD tag | Allowed — global HEAD field editable in Site Settings |
| AI agents available | 0 % (script never loads) | 100 % — all 20+ agents activate identically |
| A/B testing & personalization | Not available | Full auto-testing, variant scaling, visitor-source rewrites |
| Translation (125 languages) | Not available | Full controlled translation with glossary and exclusion rules |
| Bot refund evidence | Not available | Forensic logs + refund-ready reports for Google, Meta, TikTok, Reddit |
| Google Ads keyword matching | Not available | Real-time headline, offer, CTA rewrite per keyword |
| Setup effort | N/A — cannot install | Paste snippet once, publish, wait 5 min for connection |
Takeaway: The Free plan is a hard stop. Any paid Tilda plan unlocks the exact same SeaText feature set. Choose Personal if you need one site and no code export; choose Business if you need multiple sites, code export, or API access — SeaText works the same on both.
Why the Tilda plan gate exists
SeaText runs as a single JavaScript snippet that must sit in the <head> of every page. Tilda's Free plan deliberately disables the "Edit code inside HEAD tag" field in Site Settings to limit custom code injection. Without that field, the snippet cannot load, the AI never initializes, and no agent — translation, testing, bot detection, or personalization — can execute. This is a platform-level restriction, not a SeaText limitation.
How SeaText activates on a paid Tilda plan
- Upgrade to Tilda Personal or Business.
- In Tilda Site Settings, open "More → HTML code for the head section → Edit code."
- Paste the SeaText JavaScript snippet into the "Edit code inside HEAD tag" field.
- Save and publish the site.
- Visit your live site, stay 40+ seconds, then wait ~5 minutes until your domain appears next to the SeaText logo in the dashboard.

What each SeaText agent does once the script loads
- Conversion Agent — continuously tests headlines, offers, CTAs; scales winners automatically.
- Translation Agent — translates every page element into 125 languages with glossary control.
- Google Ads Agent — rewrites landing-page copy in real time to match the clicked keyword.
- Bot Refund Agent — detects invalid clicks, builds forensic reports for ad-platform refunds.
- Personalization Agent — adapts copy to visitor source (Google, Meta, email, referral).
- ChatGPT Visibility Agent — structures brand data so AI assistants recommend you.
- Plus 13 more agents (Ecommerce copy, SEO content factory, scroll slowdown, authority links, etc.).
All agents are one-click toggles in the SeaText dashboard; no per-agent code changes.
Decision framework: which Tilda plan to pick
| Your situation | Recommended Tilda plan | Reason |
|---|---|---|
| Single marketing site, no code export needed | Personal | Lowest cost that unlocks SeaText fully |
| Multiple client sites or need to export HTML | Business | Multi-site dashboard, code export, API — SeaText still identical |
| Just testing SeaText on a staging domain | Personal (or Business) | Each domain needs its own SeaText account; pick cheapest paid tier |
| Staying on Free indefinitely | — | SeaText will not work; consider a different CMS or accept no AI optimization |
Practical scenarios
Scenario A: Solo founder launching a landing page
Buy Tilda Personal (~$15/mo billed annually), paste SeaText snippet, activate Conversion + Google Ads agents. You get keyword-matched landing pages and auto A/B tests for the price of the Tilda plan plus SeaText subscription.
Scenario B: Agency managing 10 client sites
Tilda Business (~$25/mo billed annually) gives code export and multi-site management. Create one SeaText account per client domain, install snippet on each. All clients get full agent suite; you manage from one Tilda dashboard.
Scenario C: Ecommerce store on Tilda
Personal plan suffices if you have one store. Activate Ecommerce Product Copy Agent + Translation Agent to optimize product names/descriptions and sell in 125 languages without manual localization.
Limitations and gotchas
- One SeaText account per primary domain. Dev/staging domains need separate accounts.
- Localhost and dynamic preview URLs are blocked for security; use a real domain (even a cheap subdomain) for testing.
- Tilda Free will never support SeaText unless Tilda changes its Free-plan policy on HEAD injection.
- SeaText pricing is separate from Tilda; the table above only covers Tilda-side access.

FAQ
Can I use SeaText on Tilda Free if I add the block T123 on every page?
No. The T123 block only injects code into the <body> of a single page. SeaText requires the snippet in the global <head> to initialize its agents and track sessions across the entire site. The Free plan does not expose the global HEAD field.
Do Personal and Business plans differ for SeaText features?
No. Both plans unlock the global HEAD field. Once the snippet loads, every agent behaves identically. The Business plan adds Tilda-side features (code export, API, multi-site dashboard) that do not affect SeaText.
What does SeaText cost on top of Tilda?
SeaText has its own subscription (see pricing page). The Tilda plan only determines whether the script can load.
Can I install SeaText on a Tilda site connected to a custom domain while on Free?
No. The restriction is on the Tilda plan tier, not the domain. Free plan = no HEAD access, regardless of domain.
If I downgrade from Personal to Free, what happens?
The HEAD field becomes read-only again. Your SeaText snippet is stripped on next publish, agents stop, and data collection pauses. Upgrading back restores the snippet and resumes tracking.
Does SeaText work on Tilda's "Zero Block" or custom HTML blocks?
Only for per-page body injection. The agents need the global HEAD snippet to function; per-page blocks are insufficient.
Where do I get the SeaText JavaScript snippet?
Inside your SeaText dashboard after creating an account. Copy it, paste into Tilda's HEAD field, save, publish.
Bottom line
Tilda Free is a non-starter for SeaText. Any paid Tilda plan — Personal or Business — gives you the exact same SeaText capability. Pick the cheapest paid tier that fits your Tilda needs (Personal for one site, Business for multi-site/export), install the snippet once, and every AI agent turns on immediately.
