Perplexity searches the whole web every time. Pith remembers the specific sources you chose to read.
Perplexity is an excellent AI answer engine: ask anything and it runs a fresh search across the public web, then writes a cited answer in seconds. That makes it superb for discovery and ad-hoc research. Pith does something different. It is the persistent, cited memory of the specific sources you decided to save, organised into concept pages — a wiki where every claim links back to the bookmark it came from. Perplexity reaches outward into everything published; Pith reaches inward into everything you have actually read. For a consultant, that distinction is the whole point: you do not want an answer from the open web, you want an answer from the material you and your team have vetted.
Side by side
| Attribute | Pith | Perplexity |
|---|---|---|
| Knowledge source | Your curated library — only the sources you chose to save and read | The live public web, searched fresh on every query |
| Persistence | A growing library that accumulates across months of reading | Per-query; nothing is retained as your personal corpus |
| Citations | Every claim links to your own saved bookmark and its original source | Citations to public web pages it found during that search |
| Curation & trust | You picked the sources, so you trust the inputs by construction | Picks sources automatically; quality depends on what ranks that moment |
| Per-client knowledge | Separate shared knowledge spaces per client engagement | No notion of client-scoped, shared reading |
| Audio briefings | Audio and text briefings from your saved material before a meeting | No persistent briefing built from your own library |
| Output | Persistent concept wiki pages you can revisit, edit, and share | Answers in a chat thread (saveable, but not a structured wiki of your reading) |
| Real-time / breaking topics | Only as current as what you have saved | Strong — live web search surfaces breaking and very recent material |
| Open-web discovery | Not its job — it knows only what you saved | Excellent — built to explore topics from scratch |
| Works together | Discover with Perplexity, save the good sources into Pith to remember them | Great front-end for finding sources worth saving |
| MCP / assistant access | Queryable from Claude and ChatGPT via MCP against your own library | Has its own API/assistant, but over the public web, not your corpus |
| Data residency | Frankfurt, Germany (GDPR); your data is not used for training | US-based provider |
| Pricing | Flat per-seat | Per-seat subscription (Pro / Enterprise tiers) |
| Best for | Recalling and briefing from the reading you and your team have done | Answering open questions and discovering new material fast |
When Pith wins
You want answers only from sources you chose to trust
Before a board presentation you need a defensible position, not whatever ranks on the open web today. Pith answers from the reports, articles, and analyses you deliberately saved — and every claim links back to that exact bookmark. You can stand behind the inputs because you selected them.
You want your reading to accumulate instead of evaporating
Every article you read for a project should make you smarter on the next one. With Perplexity each query starts from zero. With Pith, six months of saved reading becomes a searchable concept wiki that keeps compounding — your own institutional memory rather than a fresh search each time.
Per-client briefings from your saved material
You keep a separate knowledge space per client. The morning of a meeting, Pith hands you an audio or text briefing built only from what your team saved for that engagement — cited, scoped, and consistent with everything you have already told the client. An open-web search engine cannot produce that, because it does not hold your client-specific reading.
Where Perplexity wins
Where Perplexity wins
If you are exploring a topic you have not read yet, chasing a breaking development, or need the very latest published numbers, Perplexity is the better tool — it searches the live public web and will surface things that are nowhere in your library. Pith only knows what you saved, so it is blind to material you have not encountered. The honest division of labour: use Perplexity to discover, use Pith to remember. Many consultants run both — Perplexity to find the good sources, Pith to retain and brief from them.
FAQ
Can Pith replace Perplexity?
Not really, and it is not meant to. Perplexity is an open-web answer engine for discovery and real-time questions; Pith is a persistent, cited memory of the sources you specifically saved. They solve different problems. Most users keep both: Perplexity to find material, Pith to remember and brief from it.
Does Pith search the web like Perplexity?
No. Pith deliberately answers only from your saved sources — the bookmarks you chose to keep. It does not run a fresh public-web search on every query. That is the point: you get answers grounded in material you trust, not in whatever the open web returns that moment.
Are Pith's answers cited?
Yes. Every claim on a Pith wiki page links back to the bookmark it came from, and through it to the original source. Perplexity also cites, but to public web pages it found during that search; Pith cites the specific reading you saved.
What does 'persistent memory' actually mean here?
Your saved reading is organised into concept wiki pages that stay and grow over time. Read ten articles on a topic over a quarter and they consolidate into one cited page you can revisit. Perplexity answers per query and does not build a lasting corpus of your reading.
Can I get audio briefings like a research summary?
Yes. Pith generates audio and text briefings from your saved material — useful right before a client meeting. These are built from your own library, not from a fresh web search.
Does Pith keep client knowledge separate?
Yes. You can maintain a shared knowledge space per client, so briefings and wiki pages stay scoped to the right engagement. Perplexity has no equivalent client-scoped, shared reading model.
Where is my data stored?
In Frankfurt, Germany, under GDPR, and your data is not used to train models. Perplexity is a US-based provider, which matters for many DACH consulting engagements with data-residency requirements.
Can I query Pith from Claude or ChatGPT?
Yes, via MCP. Your assistant can answer from your Pith library — your saved, cited reading — rather than from a generic public-web search.
Should I use both Pith and Perplexity?
That is the recommended setup. Use Perplexity for open-web discovery and breaking questions, then save the sources worth keeping into Pith so your reading accumulates into a cited, briefable memory you and your team can return to.
