Claude

giselle

“Claude powers the intelligence behind Giselle's AI workflows. We leverage the full Claude family — Haiku for fast, cost-effective tasks on our free tier, Sonnet for balanced everyday workflows, and Opus for the most demanding reasoning challenges. Extended Thinking lets our workflows reason through multi-step problems, while multimodal capabilities enable understanding PDFs and images. The API's reliability and Claude's unique ability to follow complex instructions make it perfect for orchestrating sophisticated AI workflows. Thank you for building AI that truly thinks!”

Blink.new

“Reliable SOTA AI models.”

Slashy

“We chose Claude because it is strong at understanding long, messy context and producing thoughtful, natural writing. That makes it especially useful for email workflows that depend on full threads, meeting notes, and CRM history.”

Zed

“We're piloting Anthropic's new Fast Edit mode for Claude 3.5 Sonnet with a small set of Zed users.”

Human Behavior

“Claude powers our agents, including the coding agent that opens PRs”

Cekura

“We use Claude models for parts of automated scenario generation, evaluation and building some of our pre-defined metrics”

Modelence App Builder

“Modelence App Builder is powered by Opus - world's leading coding model”

Skippr AI

“One of our LLM providers, using multiple for different tasks, along with our own agent skills”

Youkti

“Orchestrator synthesis, email scoring, coaching tips, meeting prep, weekly summaries”

THEO Growth

“Claude's advanced language understanding capabilities have been instrumental in shaping THEO's context-aware AI interactions and megaprompts in chains.”

AI Emaily

“Claude writes the replies that actually sound like our users. Best-in-class at tone, instruction-following, and staying safe on untrusted email content. It's why "drafts in your voice" works.”

onlook

“• Best at following nuanced design/editing instructions; fewer retries when transforming real React/Tailwind code. • High context windows make full-repo understanding practical for Onlook’s AI edits. • Reliable tool use and harmlessness out of the box reduces guardrail code we’d otherwise write. • Net: higher quality code changes without needing large amounts of prompt engineering.”

MindPal

“You can select Claude from Anthropic, arguably the smartest models, to power the AI agents you build on MindPal!”

QualGent

“Superb for long-context reasoning and agent supervision.”

Vamah.ai

“One of the models power our agent”

Composio

“The LLM engine that made it possible for the SWE agent to efficienly use tools, decide steps to be taken, and code geneartion.”

FirstQuadrant

“Claude powers some of the most nuanced and context-aware conversations in FirstQuadrant. A foundational model that we deeply rely on.”

RightNow AI

“Claude powers our AI optimization”

LaunchSafe

“The brain behind our security agents. Claude Opus reasons through code like a senior pentester — finding exploit chains, not just pattern matching. Massive context window + reliable API. Nothing else comes close.”

RunLLM

“Claude 3 Opus handles longer context and nuanced conversation better than most. Great for logs, long-form reasoning, and fallback flows. Best long-context memory and thoughtful responses.”

Byterover

“We used SDK for Anthropic's AI models.”

Databox

“Routines run without anyone watching. That means the reasoning has to hold up on its own, no follow-up question to catch a mistake, no chance to rephrase and try again. Claude does the actual analysis behind every run: reading the data, working out what changed and why, and writing a result that has to be right the first time, because for most runs, no one checks it before it lands in someone's inbox.”
