Perplexity is built for cited answers from web research, but Reddit users report sharp cuts to Pro research limits and frustration with service changes. If you’re leaving, pick based on what you need next: Skywork AI for cited-source research, Gemini for a storage-and-AI bundle, or Grok for live X and web search citations. ChatGPT, Kimi and Claude are also options, but their strengths differ. Prices below are starting prices from the published plan summaries; check each provider’s current limits before subscribing.
01Why people leave Perplexity
Research limits fell sharply
One Reddit commenter says Perplexity’s research allowance dropped from 600 a day to a few a month. Treat that as a user report, not a universal limit.
Annual plan changes upset users
A Reddit user says their service changed after an annual renewal and says they had expected unlimited searches. Their account describes one subscriber’s experience.
Some users see little progress
A Reddit thread says features do not seem to be improving. The available excerpt does not identify which features or establish how broadly users share that view.
02The alternatives, ranked by fit
- Cited research and exports
Skywork AISkywork AISkywork AI is the closest fit here if you’re leaving because research answers need sources. Its listed strengths include research with cited sources, several content formats and office-file exports. The starting price is $12.50, with a free plan listed. That gives you a research-focused alternative without assuming it matches Perplexity’s workflow feature for feature.
Trade-off: Check the credit math and renewal terms before paying.

$12.50/mofree plan - Low-cost AI bundle
GeminiGeminiGemini starts at $4.99 and has a free plan, making it the lowest listed entry price among these picks. It suits casual multimodal chat users and people who value an AI-and-storage bundle. One commenter on Reddit recommends it as a Perplexity replacement, but that is a personal recommendation, not a guarantee of equivalent research limits.
Trade-off: The published summary flags Reddit coding complaints as a concern for pro work.
6.1/10from
$4.99/mofree plan - Free text chat
ChatGPTChatGPTChatGPT is worth considering if your Perplexity use is mostly text chat rather than cited web research. The published summary lists a free plan and describes its free tier as generous, with unlimited text chat. Paid plans start at $8. It also lists pooled Business-seat usage and tiered Pro reasoning as reasons to consider it.
Trade-off: Published plans do not say exactly what you get for the money.
6.8/10from
$8/mofree plan - Live X and web search
GrokGrokGrok is a closer match if you want live X and web search citations. The published summary also lists voice and multi-agent workflows for power users. It has a free plan and starts at $8, so it is a relatively low-cost option to compare before renewing Perplexity, especially if X is already part of your workflow.
Trade-off: The summary flags reported usage-cap changes and vague overage pricing.
5.6/10from
$8/mofree plan - Long-document research
KimiKimiKimi makes sense if your research involves long documents and you also want agent-based office tasks. Its listed strengths include coding and research together, which may suit users who want more than a search-and-answer tool. Kimi has a free plan and starts at $15, putting it near Perplexity’s listed starting price.
Trade-off: Paid tiers and reported slowdowns weaken the value case.
6.2/10from
$15/mofree plan - Writing and document work
ClaudeClaudeClaude is a reasonable switch if you relied on Perplexity to support writing or work through documents, rather than mainly to find cited web answers. The published summary lists writing, PDFs, images, data and coding help among its strengths. There is a free plan, and paid access starts at $17.
Trade-off: Check usage limits before paying for more.
