Why SeerKits
Built for people who care about speed, privacy, and getting work done
Local-first Processing
Most tools run entirely in your browser using WebAssembly and native APIs. Your files stay on your device unless a specific job requires server assistance.
Fast & Free
No queues, no subscriptions for everyday tasks. Start processing immediately with generous free limits for personal and professional use.
Cross-platform
Works on Windows, macOS, Linux, iOS, and Android browsers. Need offline or batch workflows? Continue in the Seer app ecosystem.
Privacy by Design
We do not sell your files or use them for training. Clear upload boundaries, automatic deletion after server jobs, and transparent analytics only.
Your files deserve better than “trust us”
SeerKits is built on a simple principle: process locally whenever possible, be transparent when it is not, and never keep your files longer than necessary. No account is required for web tools, and we never sell your data.
Read our Privacy PromiseLocal by default
When your browser supports the job, processing happens entirely on your device — nothing is uploaded.
Clear upload boundaries
Server-assisted tools show an explicit notice before any upload. You always know where your file goes.
Automatic deletion
Files used for server processing are deleted immediately after the job completes. We do not retain copies.
Go beyond the browser
The Seer app family extends every SeerKits category with larger file limits, batch processing, offline workflows, and pro-grade controls — same privacy-first approach, more headroom.
