SiteGPT's Starter plan is $59 a month ($39 billed annually) for 4,000 messages on its smaller model, after a 7-day trial that needs a card. Sourceteller has no subscription: 7 credits per answer (about 1 cent) and packs that never expire.
Yes. Both answer website visitors from your own content. SiteGPT adds live human takeover; Sourceteller adds cited answers from documents, a phone line on your own number, Telegram and a share link.
For steady, high volume, SiteGPT's flat plans (from $39 a month billed annually) can work out cheaper per message. For low or seasonal volume, Sourceteller's one-off packs (from $5, never expiring) usually cost less because there is no monthly fee.
SiteGPT can show links to the web pages it used, but not to uploaded files. Sourceteller links every answer to its passage, whether it came from a web page, a PDF or a scan.
