[!TLDR] Adding an AI chatbot to a small SaaS costs $0–$49/month for 95% of teams in 2026. The price range is wide because the products are genuinely different: $0 tests the question, $19/month handles up to ~1,000 conversations/month, $49/month handles ~3,500, and anything above $99/month is designed for teams with dedicated support staff. The hidden cost nobody quotes is per-resolution billing — Intercom Fin and Tidio Lyro on some plans charge $0.99 and $0.07 per resolved conversation, which turns a flat budget into a variable invoice fast.
I'm the founder of saavos. I've tested every product in this range on my own site, checked competitor pricing pages this week, and paid real invoices. This is what I found.
The short answer to "how much?"
Here's the current market for small SaaS teams, all prices confirmed from vendor pages on 2026-05-18:
| Platform | Entry paid price | Messages or conversations | Per-resolution fee |
|---|---|---|---|
| saavos | $9/month | 1,000/month | None |
| Chatbase | $32/month (annual) | 500 credits/month | None |
| Tidio | $24.17/month + Lyro add-on from $32.50/month | 100 + 50 Lyro conversations | $0.07–$0.14/resolution on some plans |
| Intercom Fin | $29/seat/month + $0.99/Fin outcome | Per-resolution | $0.99/resolved conversation |
| SiteGPT | $39/month | 4,000/month | None |
Three things stand out.
One: the gap between "looks cheap" and "actually cheap" is per-resolution billing. Tidio and Intercom look competitive on the headline number. At 200 chatbot resolutions a month, Intercom Fin adds $198 in resolution fees on top of seat pricing. That's not a gotcha — it's how the product is designed. But it's not a flat $29.
Two: message volume varies wildly. Chatbase's 500-credit Hobby tier is tight. A single visitor session with 5 back-and-forth exchanges uses 5 credits. At 100 engaged visitors per month, you're near the limit before the month ends.
Three: evaluation paths differ a lot. saavos has a no-card dashboard preview before paid install. Chatbase's no-card preview deletes bots after 14 days of inactivity. SiteGPT has a 7-day trial then it's $39 or nothing.
What $0 actually gets you
The no-card preview question is real. Most small SaaS founders want to test the thing on their actual site before paying anything.
saavos, Chatbase, FastBots, and Tidio all have evaluation paths. But they're not equivalent.
saavos preview: dashboard preview, one bot, Claude Haiku, no expiry. You can embed it on your production site and watch real visitors use it indefinitely. The only limit is volume.
Chatbase free: 50 message credits, one chatbot — but bots delete after 14 days of inactivity. If you set it up and forget about it for two weeks, the bot is gone and you rebuild from scratch. Good for an active evaluation sprint; unreliable as a permanent tool.
Tidio free: 50 live-chat conversations plus 50 Lyro AI conversations as a one-time allotment. After those run out, you're either paying or without AI capabilities.
FastBots free: dashboard preview, no time expiry. Honest no-card preview.
For a small SaaS team that wants to test with real traffic before committing: saavos and FastBots have the most useful no-card previews. Chatbase is fine if you'll test actively in the first two weeks.
What $19–$50/month gets you (the real range for small SaaS)
This is where most small SaaS teams land.
$9/month (saavos Solo): 1,000 messages/month, 1 bot, API access, Claude Sonnet 4.6. For a site with 200–800 monthly visitors at 15% chatbot engagement, you're looking at roughly 90–360 conversations per month — comfortably under the ceiling. If you're a developer, API access at $9 is meaningful: SiteGPT doesn't include API until $79/month.
$32/month (Chatbase Hobby, annual): 500 message credits/month, model selection (GPT-4o, Claude, GPT-5 variants), Notion and YouTube training sources, WhatsApp integration. The 500-credit cap is tight. The model selection and multi-channel support are real differentiators if you need them.
$39/month (SiteGPT Starter): 4,000 messages/month, 1 bot, 1,000 pages of ingestion. The message ceiling is the strongest in this price range — 4x what saavos offers at $9. For moderate-traffic sites (1,000–3,000 monthly visitors), SiteGPT's message headroom changes the math.
$24/month (saavos Builder): 3,500 messages/month, 5 bots, API access, Claude Sonnet 4.6. Right tier for a small SaaS team running multiple products or a marketing site plus a docs bot.
Tidio Growth at $49.17/month + Lyro add-on from $32.50/month: Live chat plus AI in one platform, up to 2,000 live-chat conversations, Lyro AI conversations purchased separately. Total monthly cost for live chat plus meaningful AI: roughly $80–100/month. The right call only if you need live chat alongside AI — otherwise you're paying for a surface you won't use.
The per-resolution math nobody does upfront
Intercom Fin is $0.99 per resolved conversation. Let me run the numbers.
Say a small SaaS has 300 inbound support interactions per month. A well-tuned AI chatbot resolves 60% of those — 180 resolutions. At $0.99, that's $178.20 in resolution fees. Add the $29/seat/month minimum, and you're at roughly $207/month before you add seats for your support people.
That's $2,484/year on support tooling for a team at sub-$5k MRR.
Intercom Fin is a genuine product. The per-resolution model makes economic sense when you're comparing the bot cost against a human agent's salary. At $35/hour for a support agent handling 200 tickets, one avoided hour of agent time covers 35 bot resolutions at $0.99. The math closes for companies with active support teams.
It doesn't close when the comparison is "chatbot vs founder answering Gmail at 11pm." That's the small SaaS scenario. The per-resolution architecture wasn't designed for it.
What I'd pick by team size and traffic
Solo founder, under 500 monthly visitors: Start on the no-card preview. saavos, Chatbase, or FastBots — pick whichever has the training source you need. Don't pay anything until you see real conversations in the logs and can verify the bot is actually deflecting questions.
Small team (2–5 people), 500–3,000 monthly visitors: $19–$39/month is the realistic range. If you're under ~1,000 conversations/month, saavos at $9 covers it. If you need the message ceiling or already have a large knowledge base to train on, SiteGPT's $39 Starter handles more volume for a modest premium.
Small team that needs live chat plus AI in one platform: Tidio, but budget for Growth ($49.17) plus the Lyro add-on ($32.50 minimum). That's $80+/month combined. Only worth it if your support model requires live agents alongside the AI — most early-stage SaaS teams don't.
Developer or API-first integration: saavos at $9 includes API access. SiteGPT API requires $79. Chatbase API access is available on paid plans. If building on top of the platform is a requirement, the API tier matters more than the conversation ceiling.
Multi-language audience: None of the sub-$40 options fully cover this in 2026. SiteGPT supports 95+ languages and is the clearest answer in the $39 tier. saavos is English-only until Q3 2026.
The honest setup cost nobody quotes
Every platform says "set up in 5 minutes." The realistic numbers from my own tests, time-to-live-chatbot-answering-real-questions:
| Platform | Actual setup time |
|---|---|
| saavos | ~8 minutes |
| Chatbase | ~40 minutes |
| SiteGPT | ~20 minutes |
| FastBots | ~25 minutes |
| Tidio (live chat + Lyro) | ~60 minutes |
| Intercom Fin | Demo call required; 3–5 hours minimum |
Setup time is a real cost for a small team. Eight hours evaluating five platforms is a full workday. I'd suggest picking one, giving it a real two-week test with free-tier volume, and only comparing a second option if something is clearly broken.
The Semrush 2026 AI search study found that clarity and direct answers correlate with +32.8% AI citation rates. The same principle applies to chatbot setup: simple, focused training sources outperform an everything-crawl. Three to five tightly-scoped factual pages — pricing, FAQ, key feature pages — outperform a full site crawl on answer quality every time.
What changed since 2025
Two things shifted the math in early 2026.
FastBots raised its entry tier from $16–19/month to $39/month. That move left saavos as the only product in the sub-$25 entry-paid bracket for website FAQ chatbots. Before the price change, there were two options under $20. Now there's one.
Chatbase Hobby stayed at $32/month annual and added model selection including GPT-5 variants and WhatsApp/Instagram integrations. The feature set expanded without a price increase — notable for a product that was already the feature-richest option in this range.
Both changes make the current market simpler to navigate: if price is the primary constraint, saavos at $9. If feature breadth (multi-channel, model selection, Notion training) is the primary constraint, Chatbase at $32.
