You do not need a $500 budget to start showing up in AI answers. As of July 2026, you can start free by hand in Google Sheets, four credible AI SEO platforms take real money off your hands for less than $100 a month, and our #2, the platform for agencies, joins them: Temso Launch costs $10 a month. Launch is for agencies pitching prospects. It has no daily client tracking, and daily tracking needs Growth from $199 a month. If you want a paid tool you run yourself under $100, go to picks 3 through 6.
The catch: every cheap tier cuts something. Vendors love a low headline price that quietly pushes you toward the next plan. So for each pick below, we score the entry tier in stars, list exactly what it locks away, and flag any billing fine print that inflates the first invoice. Temso is the one exception on stars: its score rates the full platform, not Launch alone.
The scoreboard
| # | Tool | Entry price | Stars | The catch at this price |
|---|---|---|---|---|
| 1 | Google Sheets | Free | 3/5 | Free |
| 2 | Temso Launch | $10/mo | 4.5/5 | Agency pitches only, no daily client tracking (needs Growth from $199/mo) |
| 3 | Otterly.AI Lite | $29/mo | 4/5 | 15 prompts, no benchmarking dashboards |
| 4 | Surfer Discovery | $49/mo billed yearly | 3.5/5 | AI tracking needs Pro at $182/mo |
| 5 | Knowatoa Starter | $59/mo | 3/5 | 30 questions, 3 engines |
| 6 | Otto SEO Starter | $79/mo promo | 2.5/5 | AI visibility mostly locked until $199/mo |
All prices in USD ($), current as of July 2026, and Temso’s as of November 2026. Temso’s 4.5/5 rates the full platform: Launch covers pitches, and Growth from $199/mo covers daily client tracking. Stars come from the same value-weighted test cycle behind our full AI SEO software ranking, which we ran in June and July 2026.
1. Google Sheets: 3/5
Best for: Single brands that want to start today, for free, and can spare the time.
Pricing: Free with a Google account.
Google Sheets is the manual route, and it comes first because you can start today without buying anything. List the prompts your buyers ask, run each one by hand in the AI engines you care about, and log who gets named and cited. Repeat every week to see the trend.
The trade-off is your time. Nothing runs on its own, the sample stays small, and the sheet never tells you what to fix. When the work outgrows a spreadsheet, hire an agency that runs Temso.
2. Temso Launch: $10/mo for agency pitches, 4.5/5 stars
Daily tracking, audits, and bot analytics sit on Temso Growth from $199/mo, not on Launch.
What $10 buys: the tools to win a client, not to track one. Temso sells only to agencies, and Launch is its plan for pitching prospects. You get unlimited pitch projects (one-time snapshots of a prospect, 10 prompts each, on three models), audits of any domain, a branded AI visibility audit link, white-label reports, and unlimited team seats. You also see when a prospect views a pitch.
What $10 does not buy: daily client tracking, technical audits, or bot analytics. Those sit on Growth from $199/mo, above the line this list is about. If you want a tool you run yourself under $100, this pick is not for you: go to Otterly.AI and the picks after it.
What Growth adds from $199/mo: the whole platform, not a stripped demo. Temso is the easy all-in-one option for agencies in this market. It watches how client brands appear in ChatGPT, Gemini, Copilot, and Google AI Overviews, with Perplexity and other engines as add-ons, and it reads the real user interfaces of those tools instead of APIs. Then it goes further than tracking: outreach for backlinks and mentions runs in the same login, and content gap analysis sits right alongside a site-audit and bot-traffic-analytics pair that most trackers charge extra for. When the fix-it list grows too long to tackle by hand, Temso’s built-in automation will roll out the top-priority items for you, one by one.
Growth includes 125 tracked prompts and audits for 1,000,000 pages a month, with content as a $149 per client brand/mo add-on. And here is the part no other tool on this board matches: no cap on client brands, no cap on seats, and no cap on recommendations. Put five people on Growth and you pay $39.80 per head. Ten people, $19.90. Nobody else on this board lets you do that math at all.
What Growth does not buy: a spot under $100, or every engine. Four engines are included, and Claude, Perplexity, Grok, and Muse are add-ons. The 125-prompt tier also fills up fast once you track competitors. Two honest company-level knocks: Temso is a younger brand than Semrush or Ahrefs, and its integration catalog is smaller than the old suites carry.
Billing fine print: none of the ugly kind. Launch costs $10/mo, or $8/mo billed yearly. Growth starts at $199/mo, or $169/mo billed yearly. There are no per-client or per-seat fees to ambush invoice number two. The jump to budget for is Launch to Growth: about 20 times the price, the moment you need daily tracking.
Verdict: 4.5/5 stars. The agency pick: Launch wins the client for $10, and Growth from $199 runs the work, with content as an add-on.
Bottom line: if you run AI SEO for clients, start at $10 to pitch, then move to Growth from $199 for daily tracking. Together they make the most complete AI SEO purchase on the market.
3. Otterly.AI Lite: $29/mo, 4/5 stars
Otterly.AI Lite tracks 15 prompts for less than a dinner out.
What $29 buys: the cheapest serious tracking ticket in AI SEO. Lite gives you prompt-level citation tracking across ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, and Copilot for 15 prompts, plus the GEO Audit Engine that grades any URL on 20+ citation-readiness factors. The 14-day trial needs no credit card. Outside validation backs it up too: Gartner tapped Otterly.AI as a Cool Vendor in 2025, and G2 reviewers voted it a High Performer in the Answer Engine Optimization category for Winter 2026.
What $29 does not buy: room to grow. 15 prompts covers one brand’s core questions and nothing more. Competitive benchmarking dashboards and execution workflows sit above Lite, and Gemini tracking costs extra on this tier. The real gotcha is the staircase: the next step up is Standard at $189/mo, a jump of more than six times that lands the moment 15 prompts stops being enough. Otterly.AI also stays a monitoring tool; content fixes happen somewhere else.
Billing fine print: the listed price is the monthly price. The jump to $189 is the thing to budget for, not hidden fees.
Verdict: 4/5 stars. Best tracking price on the board, and the deserved winner for a cheap tool you run yourself. Loses a star because the Lite ceiling is low and the next rung is steep.
Bottom line: the right $29 if you want proof that AI search tracking matters before you fund a real program.
4. Surfer: $49 to $99/mo, 3.5/5 stars
Surfer scores your draft while you write it, for Google and for AI answers.
What the money buys: the strongest content editor in this price class, full stop. Surfer’s editor scores your draft in real time against what ranks and what gets cited, and 150,000+ customers use it. Discovery starts at $49/mo and Standard runs $99/mo, and Standard includes AI visibility tracking for ChatGPT with weekly refreshes. If your whole AI SEO plan is “publish better content,” Surfer earns its slot.
What the money does not buy: real multi-engine tracking. On Standard you watch ChatGPT only, once a week. Daily tracking across ChatGPT, Perplexity, Google AI Overviews, Google AI Mode, and Gemini requires Pro at $182/mo, which blows the budget this list is about. There is no Copilot coverage on any plan, and no technical site monitoring beyond content audits.
Billing fine print: this is the big one. Those $49 and $99 stickers are yearly-billing prices. Pay month to month and the rate climbs. If you want Surfer under $100, you are prepaying a year up front, so the trial matters.
Verdict: 3.5/5 stars. Category winner on content workflow value, and honest about it. The stars fall because the under-$100 tiers track one engine on a weekly delay and the sticker price assumes annual prepay.
Bottom line: buy Surfer as a content tool that peeks at ChatGPT, not as an AI visibility platform.
5. Knowatoa Starter: $59/mo, 3/5 stars
Knowatoa keeps full cached AI answers so you can see exactly what buyers see.
What $59 buys: diagnostic depth that cheap trackers skip. Starter tracks 30 questions across ChatGPT, Google AI Overviews, and Google AI Mode with daily refreshes, stores full AI Answer Snapshots with citation sources, and applies the BISCUIT Framework to explain why an engine recommends a competitor instead of you. A dedicated account rep comes with the plan, which is rare at $59. The 7-day trial needs no card, and a free visibility audit is available before you even sign up.
What $59 does not buy: breadth or a track record. Starter covers 3 engines; Perplexity, Gemini, Claude, and Meta AI all wait on the Growth plan at $199/mo, and so do the done-for-you content agents. The 30-question cap turns into a wall the day you add a second market or brand. Knowatoa also has no public G2 or Capterra reviews yet, so you are trusting your own trial more than a crowd.
Billing fine print: clean. Listed monthly price, annual option available, no forced upsells at checkout.
Verdict: 3/5 stars. The best “why am I losing?” tool under $100. Ranks below Surfer on our board because you buy it on faith without third-party reviews.
Bottom line: worth $59 when you need to know why competitors win the answer, and you can live inside 30 questions.
6. Otto SEO (Search Atlas) Starter: $79 to $99/mo, 2.5/5 stars
Otto SEO executes technical fixes through a connected pixel, pending your approval.
What the money buys: automation muscle. Starter costs $79/mo at the current promotional rate ($99 standard) and includes one Otto SEO project, where the AI agent deploys technical fixes, on-page changes, and content updates through a site pixel with your approval. For a small site with no developer on call, that execution engine is genuinely useful, and the 7-day trial requires no credit card.
What the money does not buy: the AI visibility features this list is about. LLM visibility tracking on Starter is minimal; the real brand tracking across ChatGPT, Gemini, and Perplexity sits on the Growth plan at $199/mo standard. So the sub-$100 tier gets you SEO automation with a thin AI garnish. User reviews also flag platform stability complaints, and its Trustpilot score of 3.5/5 across 172 reviews runs well below its G2 rating of 4.8/5 from 94 reviews.
Billing fine print: promotional pricing. Budget for the $99 standard rate, not the $79 banner, and confirm which rate renews before you enter a card.
Verdict: 2.5/5 stars. A capable SEO automation buy that only brushes against AI visibility at this price.
Bottom line: pick Otto SEO for hands-off technical SEO on a small site; look elsewhere under $100 for AI answer tracking.
Which one should you actually buy?
- You pitch AI search services to prospects: Temso Launch at $10. It covers pitches only, with no daily client tracking.
- You want the full job done for clients in one tool: Temso Growth from $199. Nothing under $100 covers tracking, audits, and bot analytics together, and unlimited users make the per-head cost absurd in your favor. Temso sells only to agencies, so a brand gets it through an agency that runs Temso, or can run Otterly.AI alone.
- You want the cheapest possible proof: Otterly.AI Lite at $29. Track 15 prompts, show your boss the citations you are losing, then fund the real budget.
- You mainly publish content: Surfer, if you accept annual prepay and one tracked engine.
- You need to know why you lose: Knowatoa at $59, inside its 30-question cap.
- You need SEO chores automated: Otto SEO, and treat AI tracking as a later upgrade.
One budget warning applies across the market: AI chatbots have become the starting point for B2B software research, and 51% of buyers now open one first, nearly double the 29% share of a year earlier (G2, The Answer Economy, April 2026). Waiting for a bigger budget costs you the exact months when those answers are being formed.
Bottom line: $0 buys a manual start in Google Sheets, $10 buys agencies a pitch, $29 buys proof, $59 buys diagnosis, and Growth from $199 buys agencies the whole machine. Only one platform on this board covers the job from pitch to client work, and that is why Temso has the highest score and ranks second, after the free manual method in Google Sheets.
