What AI models does the agent use?

The agent has access to Claude, DeepSeek, Gemini, and other top models. It automatically routes to the best model for each task — you never have to think about API keys or token limits.

Yes. Each agent runs in an isolated environment. We don't train on your data, and you can export or delete everything at any time. The underlying engine (GoGogot) is open-source, so you can audit exactly how it works.

What can the agent actually do?

Browse the web, process files (CSV, PDF, images), run scheduled tasks, remember context across sessions, and communicate via Telegram or Slack. Think of it as a capable junior employee, not a chatbot.

How does memory work?

The agent maintains persistent memory across sessions. It remembers your preferences, past conversations, and task context. You can also explicitly tell it to remember or forget things.

Can I self-host the agent?

Absolutely. GoGogot is 100% open-source. Run it on your own hardware for free. cowork.ink is the managed version — we handle servers, model costs, updates, and uptime so you don't have to.

Is there a free trial?

We offer a 7-day money-back guarantee. Spin up an agent, give it real tasks, and if it doesn't save you time, we'll refund you — no questions asked.

What is the best free AI summarizer in 2026?

TLDR This and Summarizer.org are the strongest free options — both work without an account. QuillBot's free tier handles up to 1,200 words, which covers most articles. For PDFs, Jotform's free AI summarizer processes multi-page documents with no signup required.

Can AI summarize a PDF accurately?

Yes. Tools like QuillBot, Wordtune, and SciSummary are built for PDF summarization and deliver strong accuracy. For dense academic PDFs, SciSummary and Scholarcy outperform general tools by preserving methodology and key findings rather than extracting surface sentences.

Can AI summarize YouTube videos?

Yes. NoteGPT and Eightify both summarize YouTube videos by processing the transcript. NoteGPT supports timestamped chapters and follow-up questions; Eightify is faster and focused on key-point extraction. Both have free tiers.

What is the most accurate AI summarizer?

Accuracy depends on input type. For text and articles, QuillBot and Wordtune score highest. For scientific papers, SciSummary is most reliable. For audio and video, Notta claims 98.86% transcription accuracy before summarizing. All AI summarizers can hallucinate — verify key claims against the source.

When should I use a dedicated AI summarizer instead of ChatGPT?

Use a dedicated tool when you need batch processing, browser extensions, or specialized formats like research papers and video transcripts. ChatGPT and Claude are better for flexible, conversational summarization. For team workflows, [cowork.ink](https://cowork.ink) lets you build document summarization agents that run on every file upload automatically.
