Why our AI tools stand out
Best-in-class models
We curate open-weight and commercial models (Llama, Whisper, SDXL) and auto-route each task to the model that performs best for your language.
Private by design
Inputs are never used to train any model. Your text, PDF, or image stays on our infrastructure and is deleted within 1 hour.
11 languages supported
Translate, summarize, or rewrite in English, French, Spanish, German, Portuguese, Italian, Chinese, Japanese, Korean, Arabic, and Russian.
No usage cap
Free tier gives unlimited calls. Premium caps only exist for very long inputs (>100 MB audio, >300-page PDF).
AI tools — frequently asked questions
Which AI model do you use?
We auto-route each request to the best-fit model (Llama-3.1, Mistral, Whisper, Stable Diffusion). You don't need to choose — we benchmark regularly and pick the strongest free-tier option.
Is my input used to train models?
Never. FileSwiftly does not resell, store beyond 1 hour, or forward any user input to any training pipeline.
How accurate is the PDF summary?
For typical business/academic PDFs under 100 pages, our summary tool captures the main thesis, key findings, and actionable conclusions with ~85-90% fidelity vs human-written summaries. Longer documents get a hierarchical summary.
Does AI transcription work for my accent?
Yes — our transcription engine (Whisper-large) handles 50+ accents and 90+ languages accurately. Very noisy audio or strong dialects may reduce accuracy; we display a confidence score.
Can I batch-process multiple files with AI?
Yes, up to 25 files per batch in the free tier (tool-dependent). For higher volumes, contact us for a simple API.
