Short answer
We audited the published pricing of 17 AI-native products, Synter included, across four groups: AI app builders, coding agents, AI advertising platforms, and the products we actually compete against in sales evaluations. Every self-serve product except one coding agent (Amp) requires a monthly subscription before a customer can pay for more usage, and the enterprise AI advertising platforms we are evaluated against are either demo-gated with no public pricing, or reported by third parties to have a monthly floor in the thousands of dollars. Synter is the only AI advertising platform in the index with a permanent free tier and zero required commitment: start with 1,000 free credits a month, then $25 per 1,000 as you go.

Methodology
Every price in this index comes from a vendor's official pricing page, fetched directly, or from independent third-party reporting where a vendor does not publish pricing. We do not publish figures from private vendor proposals shared with us in confidence, even where we have seen them; where a vendor's pricing is not public, we say so rather than estimate. We also did not use secondhand review sites as a pricing source unless a vendor's own page was unavailable.
We grouped products into four sets: AI app builders (v0, Replit, Lovable, Bolt.new), AI coding agents (Amp, Cursor, Claude Code), direct AI advertising competitors (Ploy.ai, GoMarble, Ryze, HyperFX, AdCreative.ai, Sprites, Smartly.io), and the enterprise platforms we have been evaluated against directly in customer deals (Pixis, Kovva). The first two groups establish the pattern across AI-native software generally; the second two are who we actually compete against for a customer's business. Those 16 vendors, plus Synter itself, make up the 17 products in the index.
Every Product Requires a Subscription, Except Two
Across all 17 products, only Synter and Amp let a customer pay for usage without first committing to a monthly plan. Amp has no permanent free tier for new users as of this writing. Synter is the only product in the index that combines a permanent, quantified free allowance with zero required commitment.

The Economist's Big Mac Index works because the burger is the same everywhere, so its price reveals what each economy actually charges for an identical good. AI agents need the same instrument. So we define one standard unit and price it across the industry from published rates only.
One Standard Agent Task, defined
A single autonomous agent run that takes a goal from instruction to verified deliverable: roughly 40 model calls consuming about 400,000 tokens of model I/O (300K input including tool results, 100K output including reasoning). That is the shape of a real mid-size task: launch an ad campaign, build and ship a small feature, produce a sourced research report. Anyone can reprice this basket against any vendor's published rates.
| Product | Price of one Standard Task | Basis (July 2026) |
|---|---|---|
| Synter | $5.00, exact | Posted per-action price: a full campaign launch is 200 credits at $25 per 1,000. The only product in this index with a posted per-task price. |
| Claude Opus, raw API | ≈ $4.00, compute only | Anthropic's published $5/$25 per million tokens times the standard profile. The agent harness, ad platform integrations, and approval layer are not included at any price. |
| Claude Sonnet, raw API | ≈ $2.40, compute only | Anthropic's published $3/$15 per million tokens times the standard profile. Same caveat: compute is not a finished task. |
| Amp (Sourcegraph) | ≈ compute cost | Usage passthrough with a $5 minimum purchase; per-task cost tracks the underlying model spend. |
| Cursor, Claude Code, v0, Replit, Lovable, Bolt.new | Not computable | Subscription plus credits or quota; per-task consumption is unpublished, so the price of one completed task cannot be determined before you buy. |
| AdCreative.ai, Ryze, HyperFX, Sprites, GoMarble, Ploy.ai | Not computable | Subscription-gated with no per-task pricing published. |
| Pixis, Smartly.io, Kovva | Undefined | No public pricing at all. |
Read the index bottom-up and the finding is stark: on 13 of the 17 products audited, the price of one completed agent task cannot be computed from public information, and on three of them not even the price of the door is public. A unit of agent work is only priceable at all on usage-based products, and only Synter posts the finished task itself as the unit. That is the entire argument for usage pricing in one table: you cannot comparison-shop work you cannot price.
Methodology: published vendor pricing as of July 2026 only, per the audit table below. The standard task profile (40 calls, 400K tokens, 3:1 input:output) is stated so anyone can recompute or contest it; where a vendor publishes neither a unit price nor consumption rates, the index value is reported as not computable rather than estimated. We will reprice this index as vendors change their pricing.
The Per-Unit Index: What a Dollar of Agent Work Buys
Subscriptions hide the unit of work; usage pricing exposes it. So here is the comparison that subscriptions make impossible: the published price of one unit of AI work, normalized across the products that publish one at all. A Synter credit is 2.5 cents ($25 per 1,000), and every agent action has a posted credit price, so the cost of a finished task is knowable before you run it.
| What you buy | Published price | What one unit gets you |
|---|---|---|
| Synter credit | $0.025 ($25 per 1,000) | A metered share of a completed advertising task, executed against your real ad accounts with approvals and an audit trail |
| Raw model tokens (Claude Sonnet, Anthropic published API pricing, July 2026) | $3 per million input / $15 per million output | Raw model compute. The agent loop, tool integrations, ad platform APIs, approvals, and monitoring are yours to build and maintain |
| Subscription AI ad platforms in this index | $39 to $4,000+ per month before usage | Access. The subscription is the price of the door; work done behind it is not itemized |
And because Synter meters per action, the per-task math is public. These are the posted rates, in credits and dollars:
| Agent action | Credits | Dollar cost |
|---|---|---|
| Budget optimization run | 5 | $0.13 |
| Chat analysis (agent reply with data pulls) | 45 | $1.13 |
| AI display creative | 80 | $2.00 |
| Full campaign launch | 200 | $5.00 |
| Extra connected ad account (beyond plan allowance) | 200/month, falling to 120 then 80 at volume | $5.00/month, falling to $3 then $2 |
Yes, a Synter credit costs more than the raw tokens underneath it. That spread is the point: it is the price of everything between a language model and a launched campaign. Five dollars buys a campaign built, checked against your accounts, and shipped through official platform APIs with an approval trail. The raw-token route buys the model's attention; the harness, the integrations to 20+ ad platforms, and the accountability layer are left as an exercise for your engineering team. Compare that five dollars to what the same launch costs in a media buyer's hour, or to a month of a subscription seat that ships no work at all, and the unit economics of paying per task explain themselves.
The Enterprise Pattern: Per-Seat Pricing or No Pricing at All
Zoom out from any single vendor and a pattern holds across enterprise AI advertising platforms: pricing is either per seat, per month, on top of a required subscription, or not published anywhere and gated behind a sales call. Smartly.io, one of the category's largest incumbents, publishes no pricing page at all; third parties report a monthly floor in the thousands of dollars, billed as a percentage of managed ad spend. Kovva, a newer entrant, gates access behind an application form with no public pricing disclosed.
Synter's pricing does not depend on team size or ad spend: $0 in required commitment, then $25 per 1,000 credits only for the work the agents actually do, with execution across every core ad platform from the first day.
Execution, Not Just Reporting
Pricing is half the comparison. The other half is what a platform's AI agents can actually do inside an ad account. Google's official Google Ads MCP server, released in 2026, is read-only: it can analyze a campaign but cannot pause it, change a bid, or launch an ad. Synter's MCP server executes campaign changes on 12 ad platforms, including Google, Meta, LinkedIn, TikTok, Reddit, X, and Microsoft, with reporting across 19 ad platforms in total. See our full MCP server comparison and Google Ads MCP servers compared for the full breakdown.
Why Pay-As-You-Go, and Why Now
A subscription is a bet a customer makes before they know whether they will use the product. A purchased credit is a bet they have already placed: they bought it because they intend to use it. That difference shows up in usage data, not just in psychology, which is part of why so few software companies choose pure usage-based pricing even though it is better for the customer.
Every action a Synter agent takes is logged, budgeted, and approvable. Campaign changes carry an audit trail, manual credit purchases are capped at $10,000, automatic top-ups respect a customer-set monthly limit, and high-impact actions can require human approval. Synter builds these controls because its own agents move real advertising budgets every day, not as an afterthought.
Frequently Asked Questions
Does Synter require a subscription?
No. Synter is pure pay-as-you-go. Every account gets 1,000 free credits a month once a card is on file. Beyond that, credits cost $25 per 1,000, with an optional auto top-up and a spending cap the customer sets.
How does Synter's pricing compare to other AI advertising platforms?
Every AI advertising platform in our July 2026 audit either requires a monthly subscription before a customer can pay for usage, or hides pricing behind a sales demo. Enterprise AI ad platforms are typically demo-gated with no public pricing, or reported by third parties to have a monthly floor in the thousands of dollars. Synter is the only one with a permanent free tier and zero required commitment.
What is the Agent Task Index?
A Big Mac Index for AI agents: one standard unit of agent work (an autonomous run of about 40 model calls and 400,000 tokens, instruction to verified deliverable) priced across the industry from published rates only. July 2026 reading: $5.00 exact on Synter, roughly $2.40 to $4.00 in raw compute on Claude's published API rates before you build the harness, and not computable on 13 of 17 products because their per-task consumption or pricing is unpublished.
How does a Synter credit compare to paying for raw model tokens?
A credit prices a finished task; tokens price compute. At Anthropic's published July 2026 rates, Claude Sonnet costs $3 per million input tokens and $15 per million output tokens, and building on it directly means also building the agent loop, the ad platform integrations, and the approval and audit layer. Synter's $0.025 credit carries all of that: a full campaign launch is 200 credits ($5), executed against your real accounts through official APIs with an approval trail. The premium over raw tokens is the harness you did not have to build.
What is pay-as-you-go advertising software?
Software that charges only for the work an AI agent actually does, instead of a flat monthly seat license. Customers add credits when they need them instead of committing to a plan tier upfront.
Is there a cap on how much I can spend?
Yes. Manual credit purchases are capped at $10,000 per transaction, and automatic top-ups respect a monthly spending limit the customer sets and can change at any time.
What happens to existing Synter customers?
Existing customers keep their current plans unchanged. The pay-as-you-go model applies to new signups.
